Abstract:
The high-pressure pneumatic solenoid valve is the key element applied to the ground gas supply system in aerospace field,whose reliability is closely related with the successful launch procedure of the launch vehicle.In this paper,the failure modes of high-pressure pneumatic solenoid valve are analyzed,and the reliability improvement,reliability test and reliability assessment techniques are also introduced.The reliability of high-pressure pneumatic solenoid valve was increased to a certain extent by a series of reliability improvement designs and validation experiments,which was also proved in large-scale flight tests.
