新一代直升机的飞行试验机载测量系统

Airborne Data Measurement System for New Type Helicopter

本文主要介绍满足新一代直升机科研飞行试验要求的机载测量系统,内容包括测量系统组成和特点,该测量系统改变了传统的模拟信号集中采集、记录方式,采用可编程的分布式模块化数字测量系统,采集位于直升机各个部位的测量信号,如旋翼系统、尾桨系统、机身的应变载荷、振动、位移、温度等以及其它模拟信号、数字总线等,编码后的 PCM 数据流合并记录于机载数字记录仪,同时可挑选数据实时遥测。也简要介绍了部分配套使用的传感器和设备。

This paper mainly introduced a state of the art airborne data measurement system for a new designed helicopter.This Airborne Data Measurement System changes the traditional data ac- quisition method,by which analog signal are acquired and recorded in central equipments.This state art airborne data measurement system is a modular distributed system that uses a series of soft- ware programmable building blocks capable of signal conditioning all types of sensors and bus data from different part of helicopter.All data are digitized and recorded;a part of parameters also can be selected for telemetry.
