| 摘 要： | 针对微型飞行器体积小、质量轻、能量和带载荷能力有限的特点,设计了微型空速计,包括微小型皮托管和基于微机电系统(MEMS)微差压传感器的低速测量电路,通过机载计算机测量电压信号并计算空速值。该空速计量程为3~26m/s,质量为4.3g,精度±1m/s,已经通过国家气象局计量站进行的测试。目前已成功应用在翼展小于400mm微型飞行器的空速测量上。

| Abstract: | Micro airspeed meters were developed for Micro Aerial Vehicles that are small, light, and low power. The micro airspeed meter includes a micro pitot tube and a low-speed-measuring circuit based on a micro electromechanical systems (MEMS) differential pressure meter. An integral computer is used to measure the voltage from the pressure meter and calculate the airspeed. The measurement range is (326 m/s,) the mass is (4.3 g) and the precision is 1 m/s. The micro airspeed meter has been successfully used on unmanned aerial vehicles with wingspans less than 400 mm. |
