目前国外新一代飞机的设计中,为进一步提高飞机的性能,同时降低系统费用,采用飞行器管理系统综合管理包括飞行控制、发动机控制、机电公共设备管理等飞机平台的功能。飞行器管理系统核心是飞行器管理计算机,细粒度可配置飞行器管理计算机不同于以往基于通道容错的计算机系统,它是基于模块级容错的计算机系统,细粒度可配置飞行器管理计算机设计利用综合化技术,通过采用通用的、标准的模块,提高系统的可靠性和可用性。它既要具有飞行控制系统的多余度安全,同时又需要满足发动机控制、机电管理等不同系统、不同余度配置的安全要求。另一方面飞行器管理计算机从系统结构、容错技术等方面要适应不断变化的微电子技术和计算机技术的发展,保持飞机平台具有相对的稳定性,更要具有灵活的系统配置能力。主要介绍了细粒度可配置飞行器管理计算机体系结构、软件要求、容错结构的实现。
At present, in the design of a new generation of foreign aircraft, in order to further improve the performance of the aircraft and reduce the system cost, the aircraft management system is used to comprehensively manage the functions of the aircraft platforms including flight control, engine control and mechanical and electrical public equipment management. Aircraft management system is the core of the aircraft management computer, fine-grained configurable aircraft management computer different from the previous channel-based fault-tolerant computer system, which is based on the module-level fault-tolerant computer system, fine-grained configurable aircraft management computer design using integrated technology, Use common, standard modules to increase system reliability and availability. It not only has redundant safety of flight control system, but also needs to meet the safety requirements of different systems such as engine control, electromechanical management and different redundancy configuration. On the other hand, aircraft management computers should adapt to the development of ever-changing microelectronic technology and computer technology in terms of system structure and fault-tolerant technology, maintain the relative stability of the aircraft platform, and have more flexible system configuration capabilities. Mainly introduces the fine granularity configurable aircraft management computer architecture, software requirements, fault-tolerant structure.
