Abstract

This paper describes the development and flight testing of a compact, re-configurable, hover-capable rotary-wing micro air vehicle that could be tube launched for increasing mission range. The vehicle design features a coaxial rotor with foldable blades, thrust-vectoring mechanism for pitch/roll control and differential rpm for yaw control. The vehicle was stabilized using a cascaded feedback controller implemented on a 1.7-gram custom-designed autopilot. Wind tunnel tests conducted using a single-degree-of-freedom stand demonstrated gust-tolerance up to 5  m/s, which was verified via flight testing. Finally, the 366-gram vehicle was launched vertically from a pneumatic cannon followed by a stable projectile phase, passive rotor unfolding, and transition to a stable hover from arbitrarily large attitude angles demonstrating the robustness of the controller.
管射同轴旋翼微型飞行器的设计、研制和飞行试验
本文描述了一种紧凑、可重新配置、可悬停的旋转翼微型飞行器的开发和飞行测试,该飞行器可以通过管发射来增加任务范围。该车辆的设计特点是具有可折叠叶片的同轴转子、用于俯仰/滚转控制的推力矢量机构和用于偏航控制的差速rpm。车辆使用级联反馈控制器进行稳定,该控制器在1.7克定制设计的自动驾驶仪上实现。使用单自由度支架进行的风洞试验表明,阵风耐受性高达5  m/s,通过飞行测试进行了验证。最后,366克重的飞行器从气动加农炮垂直发射,随后进入稳定的抛射阶段,被动旋翼展开,并从任意大的姿态角过渡到稳定的悬停,证明了控制器的稳健性。
