Challenges to The Walt Disney Company

Challenges to The Walt Disney Company The Walt Disney Company Strategic Issues First Strategic Issue Walt Disney has experienced various strategic issues, and their strategic approaches have led to success. Its strategic management has identified the fact that their competitors could take advantage of the strategic weaknesses and pull the company behind in terms of market position. Although the issues are limited in such a successful company, they deserve maximum attention, as it is possible for them to act as threats towards the future welfare of the entire business. From a quick SWOT analysis, Disneys strengths are diversity and the surplus cash it attains from its business operations. Its weaknesses include the two strategic issues it is recently facing, its opportunities are expansion possibilities, and its threats include stiff competition. One of these strategic issues that Walt Disney has been facing is the loss of a good number of subscribers in the ESPN. Recently, the Entertainment and Sports Programming Network of Disney is holding fewer consumers as compared to the past years when the company began. The major reason leading to this shift of customers to other internet programs that offer similar services is the fact that watching sports with Disney has turned out to be more expensive as compared to watching the same sports in other internet platforms. Its historical market position, which was high at that time, had been attained through appealing to customers regarding prices. When it is specifically about sports, there are different ty pes of customers. Both adults and youths across the globe have high interests in sports. However, the youths appear to have more time to invest in the sports as compared to the time adults invest. Therefore, the larger portion of customers consists of young people, who in most cases are jobless or flexible in terms their jobs. It is a fact that with their flexibility regarding careers, the youth does not earn a lot of money, meaning they will always take advantage of companies that deliver services at the least cost possible. When Disney was affordable, it appealed to the two categories of customers successfully by ensuring that it is the most affordable platform in the world. However, when the internet-based competitors found a way of broadcasting sports at lower prices and others free, Disney did not pay attention to the matching of these standards. For this reason, it lost the youths mostly to other companies. Losing its portion of youths to the competitors is a great issue, whic h, were it not for other strengths that exist in the business, would have caused the downfall of Disney as an international company. Second Strategic Issue The second strategic challenge that Disney is facing in the presence of its competitors is vitality in the market. Disney is dealing with entertainment, which is all about the preferences and tastes of customers. This dealing is capable of easily leading to its downfall if the companys management does not focus on the strategic approaches of satisfying the customers thirst in terms of what they have a passion for but does not exist in the market. In case the product exists already, it is the duty of the company to modify it and make it more interesting to the customers without altering the likes but scraping the dislikes. With this sensitivity, Disney has faced criticism every time it has a new release in the market as much as it faces motivating response. Bearing in mind that the two types of responses are from customers that the company takes as a duty to please, making changes to attract a larger portion of motivating customers than critics has been an all-time operational goal th at may or may never be achieved. It becomes worse when during its evaluation, Disney realizes a loss of positive claims having turned to critics. This is always a clear message from the public that the company has made an unpleasant release and if they take it for a trend, their market position will be at stake. This is how hard it is for Disney to maintain a good market position having concentrated on the customers taste and preferences alone. Other factors such as the cost of services make the situation worse than it already is. These two strategic issues only need to be attended to with the right approach in order to make the companys future bright (Rukstad Collis, 2009). Alternative Causes of Action Reduced Quality To address the above strategic issues and realize the best course of action, it is important that attention is afforded to the nature of the issues. This can be achieved through a value chain analysis that helps to indicate the companys operational strategy and goals. The loss of Entertainment Sports Program Network subscribers must have been brought about by a faulty strategy in the organizations way of setting its standards. To solve this, the company can buy the cheaper systems adopted by competitors. When other internet service providers decided to engage in innovative ways of lowering their prices, the company did not embrace this idea, as it looked out for maintenance of quality. As a matter of fact, the internet services providers decided to adopt new and cheaper facilities that enhanced this reduction of prices to reach out to the customers whom in their opinion, watching sports had become expensive. While doing this, the first and most essential side effect they were likely to experience is the reduction of quality. Reduced Prices The company can as well alter their operations in a way to slightly reduce their prices and maintain quality at the same time. As much these services were to be availed to customers at a reduced cost, they were also to be displayed at lower qualities as compared to those displayed by Disney. In this case, the market of the ESPN was split into two. There is the lower quality of services available for those that prioritize the amount of money spent on entertainment, and the other sector of the market generates high quality of services for people who do not mind spending a fortune for the sake of quality. With this division, it means that Disney is not ready to compromise its quality of output in order to lower prices and accommodate more customers. This is how it ended up with a limited number of customers as compared to its competitors providing services through various internet platforms. Reducing prices with maintained quality will help to maintain the current customers and to bring back those that it lost to competitors. Stable Products Thirdly, the fact that Disney deals with mainly entertaining products is the main cause of the fact that it is faced with a strategic issue of dealing with customers tastes and preferences. In its market, Disney has a chance of securing its competitive advantage through dealing with motivational and educative films more than the entertaining movies. An educative product is easier to deal with in the sense that it will have nothing to do with the judgment of the customers, and the success will all depend on the effort of the company towards gathering as much knowledge in its products as possible. This way, it is possible to predict the responses of customers to its new releases. Additionally, these types of products will maintain the types of customers that the company is appealing to, bearing in mind that the youths would embrace guidance and the adults too will help respond positively to pieces of advice offered concerning their business and social lives. Just to make the point clea r, it is for a fact that Disney has invested partly in these sectors, but the entertainment has taken a better part of its products. This has not only subjected it to the risk of customers responses based on their personal tastes and interests but also on the parental force against time wastage. Their cartoon products, for instance, are found to be excessively attractive to the children to the extent that they fail to attend to other demands such as academic works. This creates a force between the cartoon products and parents as they push the children to balance all aspects of life. On the contrary, parents also utilize the products in making promises and rewarding children whenever they want them to engage in or maintain good conduct. An example is a case where the children are motivated to work harder and perform better in class in order to be allowed to watch cartoon during their holidays. All it needs to do is buy facilities that will accommodate this type of production. This wo uld make their output stable, predictable and more profiting. All the above alternatives can be implemented in Disney to stimulate its line of business (Rukstad Collis, 2009). Recommendations Evaluation The alternative of making strategic alterations to reduce the expenses of producing their products in order to lower the prices of their services is a possible approach for the ESPN issue. This will allow them to avail the same quality of services to customers at an affordable price. This means that they will be appealing to both the customers that value quality more than cost and those that are out there negotiating for lower prices. In this situation, they will have attained competition perfection in the sense that competitors that offer services at lower prices as Disney does will not be providing as high quality as that of Disney. On this note, Disney can be boosted by other secondary factors such as making sure that there is a constant flow of game displays throughout the season. This means that they will be displaying sports events even when the companies with the poor quality of facilities will be facing breakdowns for one reason or another. Disney will be the home for custome rs who are not ready for interrupted sessions while watching matches. However, if Disney decides to follow suit as its competitors and produce low-quality products, it will be faced with the con of losing customers who value quality. These qualities of attraction will not only help Disney to retain its current customers but also bring back the youth it has lost as potential customers. This way, the current position of the company in the market will be maintained, and the opportunity to expand will have been utilized to make Disneys future more promising. As its only con, Disney will experience an added cost of operating. This is why, on a personal level, I would recommend the alternative of making strategic alterations to reduce the expenses of producing their products in order to lower the prices of their services as an approach for the ESPN issue. If the cartoons and other entertainment films do not appear to be interesting to customers as the company expects it, there will be a d ecline of the income, as the customers will not purchase the product. The worst con of it is the fact that previews that are displayed before the release of the product may lead to customers shying away from the product early enough. The advantageous purpose of these previews is to help the company predict the performance of the product in the market before it is released. The response of customers may help to detect the problem awaiting the release of a new product, but it will not help in offering a solution for the problem. Therefore, although the company will avoid tampering with its good historic reputation, it will not have evaded losses as the product has already been produced, making this alternative not good enough. This is an indication that there is not short cut towards evading this instability other than engaging in more products that will promote positional security in the market. Hence, to curb the second strategic issue, I would recommend that Disney takes advantage of its stability in the market to seize the opportunity of expansion through dealing with the products that it has not dealt with before. Feasibility On the other hand, if Disney decides to embrace the cheap facilities like competitors have one to tamper with quality only for the sake of prices, they will end up losing customers that value quality, which is the major con of this alternative. Secondly, they will have performed below their operational standards of consistently maintaining the high quality of its products. The only advantage of this alternative is the fact that it will earn back its lost customers who value cheap products. The fact that the disadvantages exceed the advantages, in this case, makes this alternative not feasible. The alternative of displaying previews does not help to find solutions for the instability of products. This means that the act will not have delivered the major expectation, thus, making it not feasible. Implementation Disney should make plans to reduce the cost of running and lower the prices of their high-quality goods. This will help the company to reach out to the customers who do not watch Disney sports because of the high prices. Secondly, it should begin to take steps towards embracing other types of products in the market in order to attain stability. Since one of the strengths of Disney Company is that it always has a substantial flow of capital, this means it has the capability to indulge in the line of other products as heftily as it has done with entertainment. Therefore, all that Disneys management requires is to make decisions based on the expansion strategies that concentrate on this mission as an operational goal. Offering other genres of films and movies will allow the company to attain stability in terms of its market position. Attracting the entire market with motivational and educative products is easier than the entertainment form of attraction. References Rukstad, M. G. Collis, D. (2009).

The Cfd Analysis Of Winglets Engineering Essay

The Cfd Analysis Of Winglets Engineering Essay In this interim report, I am going to talk about the topic of my project, aims of the project, tasks performed, project timeline, discussions and conclusions. The topic of my project is CFD ANALYSIS OF WINGLETS. When I decided to choose this project I had no idea about the winglets. Therefore, I have read a lot of about winglets. I needed to learn enough about them such as what they are, where they are used, how winglets work, why they are used in many aircrafts, how many types of winglets are there, which is the most used, winglets benefitsà ¢Ã¢â€š ¬Ã‚ ¦etc. These questions will be answered later. On section 2 aims and deliverables, I talk about what I could do in my project to be a brilliant project and what I have to do to achieve it. On section 3, I will attempt to explain what the winglets are, for that I post several images. Different types of winglets and their internal structure will be studied on the second and third point. On the next point, I talk about winglets dimensions and winglet airfoil. For that, an image is shown with a classic winglet design and three winglets airfoil are shown too. On point 3.5, winglets technology is explained. Finally, blended winglets (are the most popular winglets, as you can check later) features and benefits are explained. This is the section 3, analysis of tasks. A Gantt chart will be shown to check project timeline and progress to date. My interim report finishes with discussion and conclusions. 2. AIMS AND DELIVERABLES With my project, I will demonstrate winglets are tools that improve the aircrafts performance. For that, I will attempt to demonstrate winglets reduce the aerodynamic drag so fuel consumption goes down. I will analyze a wing with and without winglet and the creation of a vortex near at the wingtip could be checked. My knowledge  and skills are not very deep in fluent and gambit so I need to improve them. Thus, this improvement will also be an important objective. Three winglets airfoil will be analyzed in Gambit and Fluent and their results will be discussed with my supervisor. These winglets airfoil are shown on section 3.4.2. 3. ANALYSIS OF TASKS 3.1 WINGLET DEFINITION Winglets are vertical extensions of wingtips that improve an aircrafts fuel efficiency and cruising range. Designed as small airfoils, winglets reduced the aerodynamic drag associated with vortices that develop at the wingtips as the airplane moves through the air. By reducing wingtip drag, fuel consumption goes down and range is extended. Aircraft of all types and sizes are flying with winglets. From single-seat hang gliders and ultralights to global jumbo jets. Some aircraft are designed and manufactured with sleek upturned winglets that blend smoothly into the outer wing sections. The concept of winglets originated with a British aerodynamist in the late 1800s, but the idea remained on the drawing board until rekindled in the early 1970s by Dr. Richard Whitcomb when the price of aviation fuel increased. Fig.3.1.1: Vortex wingtip with and without winglet. Winglets reduce wingtip vortices, the twin tornados formed by the difference between the pressure on the upper surface of an airplanes wing and that on the lower surface. High pressure on the lower surface creates a natural airflow that makes its way to the wingtip and curls around it. Since the 1970s, when the price of aviation fuel began spiralling upward, airlines and aircraft manufactures have looked at many ways to improve the operating efficiency of their aircraft. Winglets have become one of the industrys most visible fuel saving technologies and their use continues to expand. Their main functions are: improved wing efficiency translates to more payload, reduced fuel consumption (about 4% in many flights when the distance to crossing is more than 1800 Km.), and a longer cruising range that can allow an air carrier to expand routes and destinations. The figures, reproduced below, are showing two images about winglets. Fig.3.1.2: The figure reproduced above shows winglets. Fig.3.1.3: Winglets in cars. With winglets aerodynamic drag goes down, so these components are often used in car industry. Winglets are used in cars of high range or even in formula 1. 3.2 TYPES OF WINGLETS In general any wingtips that not end the wing simply horizontally are considered as some kind of a winglet. Even though in strictly technical terms Wingtip Fences are not real extensions of the wing, and Raked Wingtips do not have a vertical part, they are still widely considered as winglet variants. We can distinguish three types of winglets: wingtip fences, blended winglets and raked wingtips. The differents types of winglets are explained showing  various  images  and commenting on  the  aircraft  in  which  they are  used. 3.2.1 WINGTIP FENCE They are a special variant of winglets that extend both upward and downward from the tip of the wing. Preferred by European plane-maker Airbus, it is featured on their full product range (except the A330/340 family and the future A350). The Airbus A300 was actually the first jet airliner to feature this kind of solution by default, but it was a very small version of the tool. Provided that most of the Airbus planes (including all A320 family jets) feature such wingtip fences, this may be the most seen and most produced winglet type. Even the new Airbus A380 double-decker features wingtip fences. Fig.3.2.1.1: Airbus Winglets as seen from the outsider. Fig.3.2.2.2: Airbus Winglets as seen from onboard. 3.2.2 BLENDED WINGLETS They are knowing as the real Winglets. They are the most popular winglet type, leveraged by Airbus, Boeing, Embraer and Bombardier but also by Russian Tupolev and Iljushin. Blended winglets were first introduced on the McDonnel Douglas MD-11 aircraft in 1990 with launch customer Finnair (it also features a smaller winglet at the bottom side of the wing). In contrast to Airbus who applies the wingtip fences by default on most of their aircraft (and the winglets on the A330/340 family),  blended winglets are considered by Boeing for example as an optional extra feature on their products, except for the Boeing 747-400. For some of the older Boeing jets (737 and 757) such blended winglets have been offered as an aftermarket retrofit, these are the newer, tall designs and do not connect to the tip of the wing with a sharp angle, but with a curve instead. These winglets are popular among airlines that fly these aircraft on medium/long haul routes as most of the real fuel savings material ize while cruising. Longer flights  mean longer cruising, thus larger fuel savings. And they also server as marketing surface for airline logos or web addresses usually. 141 ship sets have been pre-sold  already as the forecasted fuel avings  range  around  4%-6% for medium/long-range flights.  Airbus earlier tested similar blended winglets designed by Winglet Technology for the  A320  series, but determined that their benefits did not warrant further development and they stayed with the wingtip fences instead.  Aviation Partners Boeing  claims that winglets on 737s and 757s have saved a collective 1.2 billion gal. of fuel since they were introduced and 11.5 million tonnes of CO2 while reducing those types noise footprint by 6.5%.  It has sold winglets to 140 airlines and 95% of all 737NGs are fitted with them. Fig.3.2.2.1: Blended Winglets on Several Aircraft Types. 3.2.3 RAKED WINGTIPS They are the most recent winglet variants (they are probably better classified as special wings),  where the tip of the wing has a higher degree of sweep than the rest of the wing. They are widely referred to as winglets, but they are better described as  integrated wingtip extensions as they are (horizontal) additions to the existing wing, rather than the previously described (near) vertical solutions. The stated purpose of this additional feature is to improve  fuel economy, climb performance and to shorten take off field length. It does this in much the same way  as traditional winglets do. In testing by Boeing and NASA, raked wingtips have been shown to reduce drag by as much as 5.5%, as opposed to improvements of 3.5% to 4.5% from conventional winglets. Airliners to use raked wingtips: Boeing 747-8, Boeing 767-400ER, Boeing 777 (-200LR; -300ER; and freighter versions) plus the new Boeing 787 Dreamliner and the Airbus A350.  The 747-8, the 787 and the A350 will have spe cial, new kind of wings, which do not have a separate winglet, but have raked,  and  blended wingtips integrated without a sharp angle between the wing and the winglet. Fig.3.2.3.1: Raked Wingtips on the new Boeing 787 and Airbus A350. 3.2.4 WING VORTEX ELIMINATOR This is a special type of winglet. A type exists of winglet that is capable of neutralizing the vortex, this winglet is named Wing Vortex Eliminator, and consists of a pipe that canalizes the air mass that happens for the top of the wing, redirecting and avoiding that the air masses of the lower surface and upper surface come together of turbulent form. Fig.3.2.4.1: Wing vortex Eliminator. The following figure shows a summary with the types of winglets and different aircrafts where they are used. Fig.3.2.1: Types of winglets. 3.3 INTERNAL STRUCTURE OF A WINGLET Fig.3.3.1: Winglet structure. The winglets are aerodynamic surfaces, with an inner structure usually two beams (they are horizontal beams that cover the wings from the insert to the end), a pair of ribs (beams perpendicular to the previous ones to stiffen the structure), and two cloths or outer flat plates that bear the way out. Depending on the type of aircraft or manufacturer, these structures are half-metal or half metal composite material. Are embedded in the wing tip, integrating in their structure, so that only removed if a problem is detected or corrosion. 3.4 WINGLETS DIMENSIONS AND WINGLET AIRFOIL 3.4.1 DIMENSIONS When I have to built winglets for CFD analysis these dimensions will not be enough. I do not include more images because they are very big. I will need to check websites where I can see general dimensions of an aircraft such as Boeings or Airbus websites. Fig.3.4.1.1: Classic winglet design. 3.4.2 WINGLET AIRFOIL The winglet airfoil must be design with the following criteria in mind: * To minimize drag at low CL conditions.   * To design the winglet airfoil to be tolerant of low Re.   * To maximize tolerance to negative alpha. The images, reproduced below, show several winglets airfoil. Fig.3.4.2.1: winglet airfoil PSU-90-125WL. Fig.3.4.2.2: winglet airfoil E197. Fig.3.4.2.3: winglet airfoil MH 201. These winglets airfoil will be used in CFD analysis. 3.5 WINGLETS TECHNOLOGY Total pressure of an incompressible fluid is the sum of static and dynamic pressure. The laws of kinetic energy govern dynamic pressure. The difference in air pressure between the lower and upper surfaces of a wing causes the air to escape around the wingtip, which reduces the available lift or the aerodynamic drag increases. The motion of the air rushing around the wingtip causes a vortex to form near the wingtip. The tip vortices cause upwash and downwash air currents that alter the direction of the free stream flow around the wing. Fig.3.5.1: Vortex at the wingtip. When  an  air mass  is crossed  by  a  wing  that  air  mass  is  separated  into  two  streams: a stream  passes  through  the bottom  of the  wing and  the  other  stream  passes through  the top  of the  wing.  Both  meet at  the  trailing edge.  However, in  the wing tip  the same phenomenon,  but  unlike  the  previous  two  air flows  converge  before reaching  the  trailing edge  creating  a turbulence  so-called  vortex.   A vortex is created near the wingtip. Thus, it is necessary put a barrier at the wingtip. This is the concept of winglets. Winglet attracted to him the vortex and it is deflected far over the wing. Therefore, the aerodynamic drag is reduced. The winglet has a tip, just like a wing, so it also produces a tip vortex, albeit a much weaker one. The winglets tip vortex is located far above the airflow over the wing, thus it has a little influence on the airflow over the main wing. They look like vortex diffusers. The installation of well-designed winglets can improve the performance of an aircraft, however, the following aspects are critical: 1) The design must be strongly customized to each new configuration; 2) Winglets introduce additional weight; 3) They increase the wing root bending moment; 4) Efficiency is proportional to the lift coefficient; 5) They can alter the aerodynamics in critical regions (ailerons); 6) Winglets are expensive. 3.6 FEATURES AND BENEFITS 3.6.1 REDUCED ENGINE MAINTENANCE COSTS Better climb performance also allows lower thrust settings, thus extending engine life and reducing maintenance costs. REDUCING THRUST WILL: Slow EGT deterioration, which prolongs on-wing life between engine shop visits. Reduce fuel flow deterioration, which results in lower fuel burn. Lower maintenance costs by increasing time between shop visits (longer on-wing life). Takeoff thrust typically reduced by 3%. Cruise thrust typically reduced by 4%. Graphic 3.6.1.1 3.6.2 LOWER BLOCK FUEL Winglets lower drag and improve aerodynamic efficiency, thus reducing fuel burn. Depending on the missions you fly, blended winglets can improve cruise fuel mileage up to 6 percent, especially important during a time of rising fuel prices. They are saving a minimum of 4% on fuel and up to 6% on our longer flights. FUEL SAVINGS FOR CONVERTED FLEET As of mid-October 2006, Aviation Partners and Aviation Partners Boeing have equipped over  1,400 aircraft with Blended Winglets. They conservatively estimate that these aircraft are saving: 146,550,000 gallons per year. 401,507 gallons per day. 16,729 gallons per hour. 279 gallons per minute. 4.6 gallons per second. POTENTIAL ANNUAL FUEL SAVINGS PER AIRPLANE 737-700 Up to 110,000 gallons 737-800 Up to 130,000 gallons 737-900 Up to 150,000 gallons 737-300 Up to 100,000 gallons 757-200 Up to 300,000 gallons 767-300ER (PD Study) Up to 500,000 gallons Table 3.6.2.1: this table shows fuel saved in Boeing ´s airplane. 3.6.3 HIGHER INITIAL OPTIMAL CRUISE ALTITUDES Winglet equipped airplanes can achieve higher operational altitudes than the baseline non-winglet equipped airplane. This results in the following: Winglet equipped airplanes can achieve higher initial altitudes eliminating the requirement for initial level-off altitudes. Winglet equipped airplanes can achieve approximately 1,200 ft higher optimal altitudes than non-winglet equipped airplanes. Graphic 3.6.3.1 3.6.4 PERMANENT FUEL PRICE HEDGE With uncertainty in fuel supplies and the continuing increase in demand, the potential for higher fuel prices cannot be ignored. Consider the average customer for the following: Average Yearly Fuel Savings (gallons per year) Additional Savings for a $0.10 Increase in Price per Gallon 737-700 Up to 110,000 gallons Up to $11,000 per year 737-800 Up to 130,000 gallons Up to $13,000 per year 737-900 Up to 150,000 gallons Up to $15,000 per year 737-300 Up to 100,000 gallons Up to $10,000 per year 757-200 Up to 300,000 gallons Up to $30,000 per year 767-300ER (PD Study) Up to 500,000 gallons Up to $50,000 per year Table 3.6.4.1 3.6.5 INCREASED PAYLOAD / RANGE CAPACITY The addition of Aviation Partners Blended Winglets has demonstrated drag reduction in the 5 to 7% range that measurably increases range and fuel efficiency. In addition, the Blended Winglets allow commercial aircraft to take off from higher, hotter airports with increased payload. This enables you to fly farther nonstops or to complete shorter missions with greater payloads and fuel reserves. 3.6.6 ENVIRONMENTALLY FRIENDLY Winglets offer the opportunity not only to improve an airplanes operation performance but also its environmental performance. Airport Noise Levels can be dramatically affected with the installation of Winglets: Noise-affected area on takeoff reduced by 6.5 %. Take-off and approach certified noise levels are lowered. Emissions: Lower fuel burn also equates to reduced emissions. Up to a 6% reduction in CO2 and as much as a 8% reduction in NOx is possible. 3.6.7 IMPROVED TAKEOFF PERFORMANCE By allowing a steeper climb, winglets pay off in better takeoff performance, especially from obstacle-limited, high, hot, weight-limited, and/or noise-restricted airports. Performance Improved climb gradients increase 737-800 allowable takeoff weight (TOW). SOME EXAMPLES INCLUDE: Chicago-Midway: ~1,600 lb additional TOW. Lanzarote (Canary Islands): ~3,500 lb additional TOW. Albuquerque, Denver, and Salt Lake City: ~4,400 lb additional TOW. 4. PROJECT TIMELINE With the Gantt chart, you can see the tasks done to date and the future tasks. I will try to follow it and I hope to finish my project on April. As you can see, on the first weeks of my project I have been finding out information about winglets. The first two weeks, I answered two questions; what are the winglets? and what are their main function?. About tenth of November, I started to collect images of winglets and began to understand winglets technology. The following week, winglet design was studied. From my presentation, I made these tasks; airfoil winglets, types of winglets and features and benefits. From now, I have to do CFD analysis of winglets. I will start in 2-D with winglet airfoil and will finish in 3-D. Winglet airfoil will be imported into a data file to a gambit where the mesh geometry and boundary types will be created. Finally, a file .msh will be created in gambit and it will be exported to fluent where the winglet airfoil will be analyzed. The procedure is the same in 3-D, however the geometry of the aircraft will be set up in Solid Edge or Catia V5 and it will be exported to gambit. 5. DISCUSSION AND CONCLUSIONS As  you have  witnessed in  this  interim  report  the  winglets  improve the  performance of  an aircraft  by reducing  the  aerodynamic  drag  and therefore the  fuel  consumption decreases. However,  when  designing  winglets  we  should  take into  account  aspects  such as they are expensive or they increase the wing root bending moment. There are also  people who think  the  winglets  are  unnecessary and  break  up  the aesthetic  of the plane. There are several types of winglets and the blended winglet is the most popular winglet type. Features and benefits of blended winglet have been discussed (http://www.aviationpartnersboeing.com/index.html). In  these  first  few weeks of  work I have  tried to  to collect  enough information about winglets  and I  reported  about  how they work, because  they  break  the vortex  generated at  the  wingtip  vortex  and how it  is generated.

The knight from the Wife of Baths Tale :: Essays Papers

The knight from the Wife of Bath's Tale Historical Background Women's rights in the medieval years were nonexistent. Women were virtually their husbands' properties. They were identified by their husbands' names and could not legally own anything. Their husbands controlled their lives. Before marriage, a woman's possessions were property of her father. An arranged marriage was the norm, not the exception. Girls were married young, often given to much older men. Marriage wasn't romantic; it was a means to form a close relationship between two families. In Beowulf, for example, Freawaru is given to Ingeld as a pledge of peace. Usually the father of the bride gave part of his wealth (land, houses or jewelry) to the new family, but it was the groom who acquired all rights to own that wealth. The husband was also the sole representative of the family in the community where all laws and court decisions were made by men. Life in the marriage wasn't easy either. Beating wives was accepted in the society. The Wife of Bath, who becomes deaf in one ear after her husband Janekin hits her, can not go anywhere to complain. Her only options are to accept it or to do what she does -- punch him back. Married women had the double duty of running the household and helping their husbands in their trade. Women who ran their own trades -- femmes soles -- still had to do all the home chores, in addition to their business duties. As Eileen Power writes, "the wife of a craftsman almost always worked as her husband's assistant in his trade, or if not, she often eked out the family income by some such bye industry as brewing and spinning..." (Power, 53). Women were helping their husbands in almost all industries, and girls, like boys, were often given by their parents to masters for learning, as apprentices. However, as Power points out, women, then as now, were often paid less than men for the same work. If a husband died and the widow had grown male children, the oldest son usually inherited the right to all the property in the family. The only way a woman could be more or less independent, then, was to be a widow without sons. Only in this case she had the right to manage her family's property. However, society deemed it to be unacceptable for a woman to be without a husband for too long, and so she had to find somebody else to marry only two or three years after her previous husband's death.

Lord Of The Flies, Human Nature :: essays research papers

Human Nature   Ã‚  Ã‚  Ã‚  Ã‚  William Golding wrote two famous works, Lord of the Flies, and â€Å"Why Boys Become Vicious†. He was awarded the Pullet Surprise for Lord of the flies. They also made this book into two different movies. William Golding’s view of human nature is mankind is naturally evil, everyone is born that way. The book Lord of the Flies is a story about a group of young boys stranded on a disserted island. They have power struggles, and eventually break up into two different groups, the savages, and the normal kids. In William Golding’s other writing, â€Å"Why Boys Become Vicious†, he describes an event that took place in England. Two ten-year-old boys kidnapped two-year-old James Bulger, and beat him to death for no apparent reason. There are many people who agree with his ontological view but I am not one of them. William Golding believed that human nature is evil; however, I believe only some people are evil.   Ã‚  Ã‚  Ã‚  Ã‚  In the essay â€Å"Why Boys Become Vicious†, Golding proves what he wrote 40 years earlier about human nature. He tells about a real life example of humans at their worst. Two ten-year-old Liverpool boys have been charged with the death of two-year-old James Bulger. They kidnapped him from a shopping center with his mother not faraway. The two boys led him outside for a long walk until they came to a large group of boys, most around the age of 10. Then for no apparent reason they all started to beat little James. When they were through he was dead. Realizing what they had done, the boys moved his body to a rail road track, hoping a train would come so that no one could tell what they had done. The train didn’t come and the two boys were caught. In this essay Golding says â€Å"we are born with evil in us and cruelty is part of this† (â€Å"Why Boys Become Vicious†2). He thinks a likely cause of evil in boys is because of their parents. â€Å"If parents are absent, if fathers do not provide strength, and mothers do not provide love, then children will plumb the depths of their nature† (â€Å"Why Boys Become Vicious†3). William Golding proves his view by giving examples of horrible people like Hitler, Stalin, and Idi Amin.   Ã‚  Ã‚  Ã‚  Ã‚  In the book Lord of the Flies, William Golding tells a story about human nature at its worst.

Question: How is my billing for electricity calculated?Answer: The manner in which the billing for the electric utility is devised, in accordance with the Department of Defense Go Army Green program, is that all like homes are placed into groupings and an average is calculated each month for each grouping based on the average consumption of the fully occupied homes in each grouping. The groupings are defined by three factors: the size of home in square feet, age of home by the date it was built, and type of home such as a townhouse. All of the homes in these groupings contribute to the floating average each month.The looting average is determined by the amount of electricity each home uses in the grouping. The top and bottom 10% of homes in each group are eliminated, as are homes that are not rented for the full month. Once this average is figured for each of the 48 groupings of homes, a 10% buffer is added above the baseline to offset any anomalies that may occur. Once this floating average is determined a family that is above the 10% adjusted baseline by $15. 00 will receive a bill for the difference between the adjusted baseline and their actual consumption.Inversely any family that falls below the adjusted b aseline by $15. 0 will receive a refund check for the difference between the adjusted baseline and their actual consumption. No bill or refund will be sent to a family until they exceed a fifteen dollar trigger and any balance less than fifteen dollars will be tracked until the account is closed or the amount exceeds the fifteen dollar trigger. Question: Is Fort Polk the only military installation with the Resident Responsibility Program?
