The invention relates to a gas vane thrust vectoring device servo driving scheme of a plug nozzle engine, which is specifically divided into a gas vane, a fixing device of the gas vane and an integrated electro-hydraulic servo control system, so that the gas vane is fixed on the surface of a plug cone, and the gas vane can be controlled to act at a specified angle according to requirements. In order to enable the gas vanes to generate large axial force and to have small axial loss at the same time, the gas vanes are evenly arranged at the 50% length position of the plug cone in the circumferential direction. In order to solve the problems of feasibility and reliability of axial fastening of the gas rudder shaft on the curved surface of the plug cone, a split type design and dual-bearing fastening are used. In order to guarantee the transmission rotation stability and accuracy of the gas vane, a servo motor is used for driving a hydraulic cylinder, and a double-rocker mechanism is formed to achieve driving. In order to ensure the flexibility and reliability of the thrust vector of the engine, a unit integrated electro-hydraulic servo system is adopted, so that each gas vane can independently realize vector control. The invention has the advantages of high structural reliability, high control accuracy and high vector maneuverability.
本发明是一种塞式喷管发动机的燃气舵推力矢量装置伺服驱动方案,具体分为燃气舵及其固定装置和集成化电液伺服控制系统,实现将燃气舵固定在塞锥表面并且可以根据需求控制燃气舵作动指定的角度。为了让燃气舵产生较大轴向力的同时有较小的轴向损失,将燃气舵沿周向均匀布置在塞锥的50%长度处。为了解决燃气舵轴在塞锥曲面上轴向紧固可行性与可靠性问题,使用分体式设计与双轴承紧固。为了保证燃气舵传动旋转稳定性与精确性,使用伺服电机带动液压缸,构成双摇杆机构实现驱动。为了保证发动机推力矢量的灵活性与可靠性,采用单元集成化电液伺服系统,使每个燃气舵可独立实现矢量控制。本发明具有结构可靠性高、控制精确性高、矢量操纵性高的优势。
