Problems solved by technology
[0003] The hydraulic debugging equipment used in the past to retract and expand the nozzle is now widely used. Usually, hydraulic equipment is used to control the nozzle mechanically and synchronously with the hydraulic cylinder to drive the regulating plate on the nozzle to perform retraction and expansion movements to realize the exhaust area of the nozzle throat. , synchronization and sealing verification and debugging, that is to say, the hydraulic debugging equipment commonly used to debug nozzles can only debug one set of hydraulic systems, and a new nozzle with thrust vectoring function adds a new set of different The hydraulic actuation system with synchronous output adds two kinds of performance debugging requirements during debugging, which cannot be completed by existing equipment
