运载火箭电气系统BIT设计流程及方法研究

Design process and method research of BIT for Launch vehicle electrical system

良好的测试性设计对运载火箭而言,可以有效地缩短发射流程,提高发射成功率,而机内测试技术(BIT)是改善系统或设备的测试性、维修性和故障诊断能力的重要途径和手段。本文以我国新一代运载火箭XX-5为背景,分析了运载火箭电气系统实现全面BIT技术的可行性,并在系统层面提出了运载火箭电气系统BIT设计的流程和方法。通过研究,本文旨在建立一套标准的运载火箭电气系统BIT设计流程,以此作为优化测试流程、缩短测试周期的依据。

For launch vehicle,great testability design can effectively shorten launch flow and increase launch success rate.BIT（build-in test）is an important technique to improve the testability,maintainability and fault diagnosis of capability performance of a system or equipment.In this paper,analysis of the feasibility of BIT for launch vehicle electrical system and the design process and method of BIT is proposed,based on the background of new generation launch vehicle XX-5.The purpose of this paper is to establish a standard set of BIT design process for launch vehicle electrical system,as the basis for Optimizing testing process and shortening the test cycle.
