In the design, we use membrane wings to provide the lifting force and the thrust force. By the wind tunnel experiment, we can realize the influence by grasping the wind speed and the angle. Due to the empirical datum, we have found out while the wing frequency is 3Hz, the biggest lifting force is approximately 3.75 kilograms, and the thrust force is approximately two kilograms. Finally, we will also carry out a real flight test.
The flight test dividedly makes an experiment both powerless force glide ability and motive flapping wing performance. The result is good, The actual flight way is approximately 30 meters, and the research obtained basic success. Besides, the tail wing rigidity and the control part should be improved to prevent the ornithopter. While the ornithopter is in a crooked condition, the ornithopter will unable to revise, it will cause a crash. In the thesis, the design method and the making process are also discussed in details.
