摘　　要：通过对几型飞机飞行控制计算机和飞行器管理计算机的架构及关键技术进行分析,可以发现其系统架构已从集中控制的联合式架构迈向了管理和控制分离的分布式架构,其功能也从单一的飞行控制功能走向了包括飞行控制、机电管理、发动机管理等在内的飞机平台级的综合化管理功能,但是飞行控制功能依然是其最高安全级别的功能。虽然因其不同的安全性需求和功能需求导致其所采用的容错技术、系统余度架构不尽相同,但是总体上分布式架构、功能综合化和COTS应用技术为其主要的一致发展趋势。Through the analysis of some flight control computers and vehicle management computers,it can be seen that the flight control computer system architecture has moved from a joint architecture to a distributed architecture with separation of managed and control,and its function has also gone from only flight control function to integrated more aircraft platform management functions including flight control,mechanical and electrical management,engine control etc,and flight control is the high safety level function.Although the fault tolerant technologies and system redundancy architectures they adopt are different due to different safety requirements and functional requirements,distributed architecture,functional integration and COTS appliance as their main trends are consistent.
