Abstract

The present disclosure provides a recyclable launch vehicle electrical system. The electrical system comprises multiple stages of systems, wherein each stage of systems comprises a first bus, a secondbus and multiple nodes, each node is connected with both the first bus and the second bus, the first buses of two adjacent stages of systems are connected with each other through a separation connector, the second buses of two adjacent stages of systems are connected with each other through a separation connector, synchronous data exchange is carried out among the nodes at fixed time intervals, each node can be connected with an independent main station, a standby main station can be started to take over control when detecting that the main station is lost, all parts can still independently complete work after separation is achieved, and thereby conditions are provided for recovery of separated rockets. The invention further provides a carrier rocket utilizing the electrical system. The system architecture not only has advantages of high bandwidth, high real-time performance, high reliability and easy expansion, but also the bus supports online switching of the main station, the system is convenient to transplant and simple and flexible in configuration, and is very suitable for a recyclable system rocket electrical system.

Description

technical field

[0001] The present disclosure relates to the field of launch vehicles, and more particularly to a low-cost electrical system suitable for recoverable launch vehicles. Background technique

[0002] The electrical system of the launch vehicle is the core system of the launch vehicle. It is responsible for signal acquisition, attitude control, timing command issuance, and control command execution of the launch vehicle. It needs to meet the requirements of high reliability and strong real-time performance. The electrical system architecture directly affects the comprehensive performance and reliability of the launch vehicle.

[0003] At present, the electrical systems of launch vehicles in active service in China are all non-recyclable structures. Most of the electrical systems adopt a non-bus system or a dual-redundant 1553B bus system. Navigation devices and rocket computers are installed on the upper stage, and disposable silver-zinc batteries or thermal batt...
