摘要
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。
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.
