Structural design of CFR main spar for human pewered aircraft main wing

Abstract

There is an old saying in the aircraft industry that you can make a brick fly, if you have enough power. For the human powered aircraft designers is even harder to create an airplane that can fly as they have less power available to use than the necessary for a small electric fire. But how it is possible? There is a team of engineers behind the aircraft working hard to improve the design and make it lighter and cheaper. It is important to know that the energy used is the one provided by the human body. The pilot pedals and transmits power through transmissions to the propeller, who print device speed to the plane. There is a control system for the aircraft’s maneuverability that allows a pleasure driving. Another important plane part is the main wing. When the aircraft begin to pick up speed the main wing suffer a deformation that allows a better maneuverability. There is one factor more to be considerate, the weight. It is important not to exceed the maximum weight that the plane can withstand flying. If the materials are not correctly chosen, the plain will not fly. In conclusion, combining the above conditions it is possible to design a plane able to fly using only human power, the thesis objective is to design an appropriate main wing structure.
