基于多信道无线传输的旋翼载荷测试技术研究

摘要

直升机旋翼系统载荷和强度飞行试验是对真实大气环境中旋翼系统应力载荷谱的研究,它提供的真实数据是理论计算所不能提供的;因此旋翼系统载荷试飞是直升机设计定型试飞中极其重要的项目;针对直升机旋翼系统载荷测试技术需求,采用模块化、冗余度和高集成的设计理念,通过多信道无线传输设计等技术,将采集的动态载荷数据调制、发射与解调,实现了多通道、高带宽和精同步的旋翼系统载荷数据采集与监控;该技术对于直升机旋翼系统载荷试飞中遇到的类似问题具有一定的借鉴意义.%Helicopter rotor system load and strength flight test is the real atmosphere environment of the rotor system stress load spectrum of the study,it provides real data can not be provided by the theoretical calculation,so the rotor system load test flight is the helicopter design stereotypes test flight is extremely important project.According to the requirements of helicopter rotor system load test technology,the dynamic load data modulation,transmission and demodulation are realized by multi-channel wireless transmission design using modularity,redundancy and high integration design.Data Acquisition and Monitoring of Rotor System Load with High Bandwidth and Accurate Synchronization.This technique has some reference significance for the similar problems encountered in the helicopter rotor system load test flight.
