Launch Vehicle Integrated Electronic System Design Based on Directed Graph Method

Integrated electronic system on launch vehicles suffers from the complex information interaction and transmission process among functional modules. To solve the problems above, a launch vehicle integrated electronic system based on directed graph was proposed in this paper. Functional modules on launch vehicles were regarded as nodes in the directed graph, while information flows were the edges among those modules. Based on the enacted directed graph, an adjacency matrix was then established to represent the complex integrated electronic system. The transfer length and arrival matrix were calculated and analyzed to optimize the whole integrated electronic system. Compared with the traditional design, the proposed system achieves a terser information interaction and transmission process. Moreover, the transmission efficiency of the proposed system can be improved by 37.5%.
