Design And Construction Of An Ornithopter

Abstract

 The first ornithopters capable of flight were toys built in the late 19th century in France. Large-scale, piloted ornithopters were first developed in the early 20th century. Piloted ornithopters come in two basic categories: engine-powered and human-powered. In this paper, we are concentrating on the procedure for the design and fabrication of flat wing ornithopter with the flapping frequency of 6Hz and wingspan of 1m. While designing an ornithopter chronological sequence should be maintained, in that we have to select flapping frequency according to predicted weight then by selecting a suitable motor we have to design gearbox for the required reduction ratio. After that, while designing wing there are different parameters like the coefficient of drag, aspect ratio, etc. optimum selection of these parameters is important. The designing tail is important as it is responsible for pitch and yaw control, during the design of tail stability and control for flight are the parameters to be considered. After the design of mechanical components selection of electronic components like battery, ESC, servomotors, controller, and receiver are selected. In this paper, we have discussed the most advantageous types of these electronic components.
