摘　　要：针对飞行器结构的复杂程度,以及飞行器风洞试验过程中需要测试数据较复杂、且无法进行实际飞行试验的现状,经过大量的实际测试和工程实践,设计了一种新型的基于MEMS传感器的飞行器气动参数测试用带式传感器阵列,可以对飞行器表面多点的压力、应变、振动、温度进行测试。经实际调试验证,该测试系统具有良好的测试精度,性能可靠,能够完成飞行器表面的多个气动参数测试,具有良好的工程化价值。Aiming at the complexity of the aircraft structures and the actuality that measured data are complex and actual flight tests cannot be carried out in the aircraft wind tunnel tests, with a large number of actual tests and engineering practices, a belt-type sensor array based on MEMS sensors for aerodynamic force parameter tests of airborne crafts is designed. The sensor array can test the pressure, strain, vibration, and temperature of the airborne craft surface. The practical tests show that the system has advantages of high accuracy and reliable performance. It can test a large number of aerodynamic force parameters of the surface of airborne crafts and has great value of application and popularization.
