A launch vehicle electrical system based on fc-ae-1553 high speed bus

Abstract

A method for testing the electrical system of a launch vehicle based on the FC-AE-1553 high-speed bus, comprising the steps of: S1, the test program starts, the ground host is initialized as a network controller of the FC-AE-1553 high-speed bus, and other devices of the electrical system are initialized It is the network terminal equipment of FC-AE-1553 high-speed bus; S2, after the test indicators of each equipment on the ground are up to standard, the ground host will transfer the control right to the integrated control computer; S3, the ground host sends a first-level engine ignition to the integrated actuator Instruction, after the integrated control computer receives the take-off, it will broadcast the take-off time globally to the FC-AE-1553 high-speed bus, and enter the navigation guidance and rocket attitude control; S4, the data management center collects the measurement data of the launch vehicle, and then The health of the rocket is assessed and the results are sent to the integrated control computer.

Description

technical field [0001] The invention relates to a carrier rocket electrical system based on FC-AE-1553 high-speed bus, in particular to a carrier rocket electrical system based on high-speed bus information interaction, belonging to the technical field of carrier rocket electrical system design. Background technique [0002] At present, the competition in the field of space launch is becoming increasingly fierce. All major aerospace countries are launching or developing low-cost launch vehicles. These rockets have a high degree of automation, a short development cycle, and strong versatility. The use of advanced intelligent development and production models greatly reduces the launch cycle and cost of rockets. , Compared with my country's traditional launch vehicle research and development model, it has great advantages. As one of the most important systems of the launch vehicle, the electrical system can achieve high reliability, health management, and rapid test launch beco...

AI Technical Summary

Problems solved by technology

Traditional launch vehicle electrical systems are large in scale and complex in structure, low in integration, complex in bus types, and low in bus throughput, which seriously affect the carrying capacity. Facing the demand for rocket fault diagnosis and health monitoring functions under the new situation, due to the high power output and high dynamic characteristics of the rocket engine, high sampling rate and high throughput of the bus are required. The traditional rocket electrical system architecture is difficult to meet, so it is necessary Develop a new generation of launch vehicle electrical system with high-speed information interaction, high reliability and high integration
