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.
