around winglets is complicated, and winglets have to be carefully designed and tested for each aircraft.” (How Things Work: Winglets). The invention of the winglet allows a reduction in drag acting upon the aircraft by converting the airflow at a wingtip into a forward force, rather than an upward force. The size, shape and angle of which a winglet is mounted to the wing, depends on the aircraft type and size. A winglet improves the overall performance of the aircraft and is beneficial to the aviation
The Boeing 737 is one of the most popular aircraft ever produced. Over 7700 in all variants have been produced, with an additional 11,275 aircraft on order. This makes the 737 the most popular jetliner to date. The 737 has a wide variety of uses, and still remains extremely popular and under high demand. Because it is such a widely mass produced aircraft, it is also a target for constant aerodynamic improvements. Boeing has looked at everything from the design of the anti-collision lights,
Wing tip devices are simply designed airfoils that improve a wing’s lift-to-drag ratio. Through this combination of increased lift and reduced drag, an aircraft can fly more efficiently with the net result being more economical fuel burn. Wing tip devices were first created in 1897, a British engineer named Frederick Lancaster created wing tip devices called wing end plates to improve the aerodynamic characteristics of the airfoils he designed (Air force Studies Board, 2007). Through the years, designers
Presented in thousands of Canadian dollars, except per share amounts** The recent economic downturn has served to demonstrate the vulnerability of Westjet global economy and in particular, the tenuous financial thread by which a considerable number of airlines around the world operate. In Canada, there continues to be an uneven playing field that serves to give Canadian operators a disadvantage. This has resulted in a considerable increase in the number of Canadian passengers who cross the Canada/U
Over the years my family has taken numerous road trips across the country. During these trips we would pass through countless wind farms which would peak my curiosity. Therefore, I decided to do some research into wind turbines. A wind turbine is a device that converts kinetic energy from the wind into mechanical energy. If the mechanical energy is used to produce electricity, the device may be called a wind generator, wind charger or wind turbine. If the mechanical energy is used to drive machinery
directions to change the direction of lift momentarily. This brief change of lift allows the aircraft to bank and change its direction. Newer more modern plane wings have what’s called winglets. Winglets, an upward curved end piece of the wing, decrease wingtip ... ... middle of paper ... ... turned by pistons, it is fueled by a combustion process using turbine exhaust to spin the prop rather, hence the term turboprop. A turbofan is what you will find on all private business jets and airliners. Instead
