摘要：
Pneumatic actuator is the key component of the flight attitude control system for air-defense missile, directly influences flying stability and attitude control ability. Missile-borne high-pressure gas provides power for pneumatic actuator through pressure reduction, which can reduce the space occupied by the pneumatic system and increase missile range by carrying more gas. For a particular type of missile, a reverse non-balanced direct-acting high-pressure reducing valve with conical clack was designed. Mathematical models of thermodynamic and static analysis were built for the valve and the design & check software were developed. The simulation models with steady and unsteady inlet pressure were built based on AMESim, and the characteristics of pressure, flow rate and spool displacement were analyzed. Results show that the pressure reducing valve has good pressure and flow characteristics under design parameters, and the theoretical calculation and simulation results agree well. © 2022 Beijing University of Aeronautics and Astronautics (BUAA).
