Abstract

The invention relates to the field of solid motor flow regulation devices, and discloses a hydraulic servo actuation system, which comprises an integral type servo controller, at least two hydraulic actuators and an integrated valve block. Each hydraulic actuator is controlled by a group of hydraulic control valve group, and the hydraulic control valve groups of the hydraulic actuators are arranged on the integrated valve block. According to the hydraulic servo actuation system provided by the invention, the control valve groups of the hydraulic actuators are integrated on the same integrated valve block, and the fluid, mechanical, electronic, electromagnetic and information processing technologies are comprehensively adopted to be highly integrated into a whole, so that the hydraulic servo actuation system has the advantages of simple structure, small volume, light weight, high reliability, excellent and stable performance, and simplicity and convenience in use and maintenance, and can better meet the installation requirements in a narrow space.

Description

technical field [0001] The invention relates to the field of flow regulating equipment for solid motors, in particular to a hydraulic servo actuation system. Background technique [0002] As aerospace vehicles, launch vehicles and other systems have higher and higher weight requirements, solid motors have become the future due to their advantages such as high specific impulse, small size, light weight, simple structure, reliable operation, good storage, and low production cost. The powerplant of choice for systems such as aerospace vehicles. As one of the key executive parts of the solid engine, the flow regulating mechanism is mainly used to control the engine gas flow to adjust the working state of the engine. Its working performance and reliability directly affect the working performance and reliability of the solid ramjet engine. [0003] In view of the small size and light weight of the solid engine, the flow regulating mechanism must adapt to the requirements of the e...
