| Abstract: | Redundant architecture design is an effective way to solve the reliability issue for the flight control computer(FCC).A redundancy architecture approach of a new triple-redundant FCC and a design method of describing FCC redundancy are proposed to meet the special requirements of high-reliability and fault tolerance in FCC system.A overall framework of the redundant computer hardware and software was designed.The reliability analysis of the approach was performed with Markov method.The influence of the fault coverage and the failure rates on the reliability of FCC was achieved.The feasibility of this redundant architecture design is proved. |
