摘　　要：介绍了余度机载计算机的余度配置方法,并以某小型飞行器多余度机载计算机为例,从同步、传输、故障综合、输入/输出表决等方面,详细描述余度管理的主要策略。飞行试验结果表明,该方法能较好地完成该计算机的所有余度管理任务,该方法也可应用于其他多余度系统。The methods to collocate the redundancy in airborne computer are described in this paper. And a multi-modular redundancy airborne computer used in small vehicle is taken to illustrate them. Particularly, the author describes the main strategies in several aspects such as synchronization, transmission, fault-synthesis and I/O. Flight results show that all the redundancy management tasks are achieved with these methods. These methods also can be used in other multi-modular redundancy systems.
