仿枫树种子微型飞行器的总体与飞行控制设计

通过模拟枫树种子独特的自旋飞行方式，设计了一种仿枫树种子的新型微型飞行器。参考枫树种子的外形与重量分布来完成该微型飞行器的总体布局设计，同时采用动态网格非定常流场方法计算分析了该飞行器不同转速下的飞行工况。根据这种飞行器独特的飞行方式，基于地磁场的方位定标，设计了这类自身无固定参考系飞行器的飞行控制方法，最后制造了样机进行飞行试验。结果表明：仿枫树种子微型飞行器具有良好的气动效率，所设计的操纵方案有效可靠，大大增加了这种飞行器的可控性和实用性。

General Layout and Flight Control Scheme for Micro Air Vehicle in Imitation of Maple Seed

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.
