运载火箭箭上电气系统基础架构研究

Research on electrical system infrastructure of launch vehicle

摘要:

运载火箭箭上电气系统主要用于完成飞行控制、参数测量以及故障检测等功能。借鉴航空IMA平台和汽车平台的思路,提出了运载火箭电气系统“1+4+N”的架构,其中“1”代表一套通用电气系统平台,“4”代表“综合电子架构+能源管理架构+总线通信架构+软件应用架构”的电气系统基础架构,“N”表示满足基础架构规范要求的各类可扩展组件。本文首先根据我国运载火箭的发展需求和技术特点,分析了电气系统功能划分,并给出了电气系统平台和基础架构的定义,结合国外先进运载火箭的电气系统架构发展现状,分析了运载火箭电气系统平台的各个发展阶段,最后归纳总结了未来运载火箭电气系统总体特征。

Abstract:

The electrical system of launch vehicle is mainly used for flight control, parameter measurement and fault detection. Referring to the ideas of aviation IMA platform and automobile platform, the concept of carrier rocket electrical system platform is proposed. The electrical system platform can be divided into two parts: infrastructure and extension components, among which the infrastructure is the key to determine the performance of carrier rocket electrical system. In this paper, according to the development requirements and technical characteristics of launch vehicles in China, the functional division of electrical system is analyzed, and the definition of electrical system platform and infrastructure is given. Combined with the development status of electrical system architecture of foreign advanced launch vehicles, each development stage of electrical system platform of launch vehicle is analyzed. Finally, the overall electrical system of launch vehicle in the future is summarized features.
