摘　　要：以某型号飞机功能试验过程中的攻角传感器为研究对象,分析攻角传感器调节测试方法中存在的问题,通过对攻角传感器工作原理的分析以及现阶段功能试验方法的梳理,提出了一套攻角传感器自动调节系统的开发解决方案。该系统采用PLC对步进电机进行控制,由步进电机通过风标加持装置对攻角传感器的风标进行调节。通过对步进电机的速度、加速度及角位移的控制实现攻角传感器的高精度调节,精度在0.5°之内,满足现场使用需求。With the angle of attack sensor test and adjustment in the process of a certain type of aircraft function test being the research object,and with the aim at the problems in the adjustment test method of angle of attack sensor in the process of functional test,a set of solutions to automatic adjustment of angle of attack sensor is proposed,by sorting out the working principle of angle of attack sensor and the current method of function test.In the system,PLC is applied to control the stepper motor,by which the the weathercock of the angle-of-attack sensor is adjusted through the weathercock blessing device.Through control of speed,acceleration and angular displacement of the stepper motor,the high precision adjustment of the angle-of-attack sensor is achieved.The test results show that the accuracy is within 0.5 degrees,which is well in line with site use requirements.
