微型飞行器在民用和军事应用方面都有很大的潜力，但为了成功部署，它们必须在现实环境中稳定运行，包括在风中飞行。为了量化微型同轴直升机在现实风条件下的性能，进行了实验研究。实验研究评估了不同的代表性场景，包括：悬停、向前飞行和降落在屋顶边缘。每个场景都在名义上无风的情况下和不同的风力水平下进行了飞行测试。使用合成风力发电系统来产生风扰动，并使用数字风速计来测量离散空间点的风力和速度。运动捕捉系统用于在飞行测试中测量飞行器的位置和姿态，并为传统的自动驾驶仪提供反馈。结果表明，在所有风环境下，性能都急剧下降。飞行观测显示，微型同轴直升机可以在小于2米/秒的微风中成功运行。
Micro air vehicles have great potential for both civilian and military applications, but for successful deployment they must operate robustly in real world environments including flight in winds. An experimental study was performed to quantify the performance of a micro coaxial helicopter in realistic wind conditions. The experimental study evaluated different representative scenarios including: hover, forward flight, and landing on the edge of a rooftop. Each scenario was flight tested in nominal no wind cases and different wind levels. A synthetic wind generation system was used to create wind disturbances, and digital anemometers were used to measure wind magnitude and velocity at discrete spatial points. A motion capture system was used to measure vehicle position and attitude during flight tests as well as provide feedback for a conventional autopilot. Results show dramatic performance degradation in all wind environments. Flight observations reveal the micro coaxial helicopter could successfully operate in light winds with magnitudes of less than 2 m/s.
