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。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
