新一代直升机的飞行试验机载测量系统

主要介绍了新一代直升机科研飞行试验要求的机载测量系统,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测量系统,可以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、温度等以及其他模拟信号、数字总线等.将数字化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.简要介绍了部分配套使用的传感器和设备.

Airborne Data Measurement System for New Type Helicopter

A state of the art airborne data measurement system for a new designed helicopter is introduced.This airborne data measurement system changes the traditional data acquisition method,by which the analog signal are acquired and recorded in central equipments.The system is a modular distributed system that uses a series of software programmable building blocks,can acquire all types of sensors' signal and bus data from different part of helicopter.All data are digitized and recorded;a part of parameters also can be selected for telemetry.
