发动机地面试验摇摆测控系统设计与实现

Design and implementation of swaying measurement and control system for liquid rocket engine ground test

某型号液体火箭发动机地面试验时需要进行双向摇摆,本项目设计了一套测控系统与配套的伺服机构控制器进行对接,完成伺服机构驱动控制、数字和模拟量参数测量、摇摆指令文件编制、试验数据分析、能源动力供给等功能。该系统基于1553B总线,使用冗余总线结构保证数据传输可靠性,与伺服机构控制器对接后进行地面联试和热试车考验。结果证明研制的测控系统各项功能、指标满足试车任务要求。

As the liquid rocket engine is required to do a two-way swaying during its ground test, a set of measurement and control system mating with the controller of the servo mechanism is designed in this project to carry out the control of the servo mechanism, measurement ot digital and analog parameters, documentation of swaying order, analysis of test data and power supply. The measurement and control system based on the base of 1553B bus and redundant bus can ensure the high reliability of data transformation. It passed the integration test and heat test run after mating withthe servo mechanism controller. The results verify that all the functions and indexes of the system can meet the requirement of the test.
