摘　　要：小型无人机体积小、速度低、带载荷能力有限,而小型硅压阻传感器具有小型化、数字化的优点,特别适合于对体积重量有要求的众多中小型无人机选用。本文结合某小型无人机空速系统的研究,针对目前多运用于小型无人机上基于硅压阻传感器的空速系统误差产生的原因进行了分析,并根据大多数无人机采用GPS导航的特点提出简便易行的校正方法。经过试飞验证,该校正法具有良好的性能和可靠性。The minitype unpiloted aircraft is of small size, low speed and has limit loading ability, but the minitype silicon piezoresistance has the features of miniaturization and digitalization, especially suits medium and minitype unpiloted aircraft which has the requirements of size and weight. This paper analyzes the reason why the airspeed system based on silicon piezoresistance sensor nowadays has error on the minitype unpiloted aircraft by combining studying of certain minitype aircraft airspeed system, puts forward simple and convenient practical calibration method as per the characters of most of unpiloted aircrafts adopting GPS navigation. This calibration method has favorable performance and reliability after being verified by the flight test.
