Design and Implementation of Flight-test Measurement System for Helicopter Rotor

摘要:

为获取旋翼载荷试飞数据,给出直升机旋翼动部件的安全使用寿命,并通过直升机设计定型试飞考核其是否能达到设计指标,需要设计一套试飞测试数据采集系统；针对旋转部件与静止部件之间的供电和数据传输问题,提出了利用感应供电与短距遥测传输技术的设计思路,介绍了测试系统方案；通过地面试验和飞行试验验证表明测试系统可靠、有效,解决了直升机旋转部件试飞测试的难题。

Abstract:

In order to obtain the flight-test data of the rotor,the safety service life of the helicopter rotor is given,and the flight-test of the helicopter is prepared to test whether it can meet the design targets or not. it is necessary to design the data acquisition system of flight-test. Aiming at the problems of power supply and data transmission between rotating and stationary components, it is proposed that the way of inductive power supply and telemetry transmission technology in the short range,and introduced that the design scheme of the testing system. Through the ground test and the flight test,it is proved that the test system is reliable and effective.
