By the simulation of the unique spin flying style of maple seed, a new type of micro air vehicle in imitation of maple seed is designed. Referenced to the appearance and weight distribution of maple seed, the general layout design for the micro air vehicle is completed, then the flight status at different rotating speed is analyzed by using the dynamic mesh unsteady flow method.The flight control scheme for this kind of aircraft is designed by magnetic field azimuth calibration according to its unique flying style. Finally, a prototype is produced for flight tests. Results show that the micro air vehicle in imitation of maple seed has good aerodynamic efficiency and the control scheme is effective and reliable, thus increasing th e controllability and practicability of this kind of aircraft.
