Reliability Design of a New-Type Nozzle Electronic Control System

In order to improve the reliability and safety of a new-type nozzle electronic control system, the failure of the system was checked, and some measures should be taken to ensure the work safety. The reliability design technology of the system was discussed, the hardware and software of the system were also introduced. And system failure, faulty reason, measures and the influence on safety were initially analyzed. Furthermore, the probability of failure and the influence on flight safety were also evaluated for safety. The results show, the reliability of the new-type nozzle electronic control system can meet flight requirement
