A hydraulic actuator is a mechanical actuator that is used to impart a unidirectional force through a unidirectional
stroke. The detailed study of various control actuations and design of typical hydraulic actuation system is need as it plays a
major role in the working of aerospace vehicle. This study involves the design of hydraulic actuation system for the flex nozzle of
a solid motor as part of thrust vector control actuation system. This actuation system is going to control the vehicle in pitch and
yaw direction during powered phase. The design, fabrication and testing of the hydraulic actuator are considered in this work.
After designing the hydraulic actuator according to the specifications, testing is done manually, to check the performance of the
vehicle by using different techniques. The actuator which is designed, fabricated and tested successfully is ready to be fitted in
the aerospace vehicle.
