Problems solved by technology

[0006] In the traditional electromechanical servo system, due to its structural design and other reasons, the larger the power, the larger the space occupied. However, with the development of launch vehicle technology, especially there are many types of equipment near the nozzle of the solid engine, the space is relatively large. In the case of tight layout and limited installation size, the traditional electromechanical servo system has been difficult to meet the requirements of launch vehicles with tight space layout

Abstract

The invention provides a thrust vector controlled electromechanical servo system. The provided thrust vector controlled electromechanical servo system comprises two electromechanical actuators, one master servo control driver, one slave servo control driver, and one servo power supply for supplying the power, wherein the master servo control driver and the slave servo control driver respectively drive and control one electromechanical actuator. The electromechanical actuators are parallel electromechanical actuators. The parallel electromechanical actuators comprise servo motors, ball screw transmission mechanisms, and gear transmission mechanisms which are drivingly connected with the servo motors and the ball screw transmission mechanisms. The ball screw transmission mechanisms are in parallel with the servo motors. By employing the parallel electromechanical actuators, i.e., allowing the ball screw transmission mechanisms to be in parallel with the servo motors, the axial space occupation of the whole electromechanical servo system is reduced effectively, accordingly meeting the requirements of design and usage at the greatest extent under the condition of seriously limiting the axial installation dimension.

Description

technical field [0001] The invention relates to the field of aircraft, in particular to an electromechanical servo system for thrust vector control. Background technique [0002] The closed-loop system for the flight control execution of the launch vehicle and its payload is generally referred to as the servo system. One of the typical applications of the servo system is to swing the liquid engine or solid engine nozzle to realize thrust vector control and complete the attitude control of the launch vehicle. The solid rocket motor uses solid combustible grains as fuel, and has the advantages of long storage time, good maintenance, short preparation time for use, and flexible use. It is one of the mainstream rocket development directions in the world. Correspondingly, the closed-loop control servo system of the swinging solid rocket motor nozzle is also a necessary control system equipment. [0003] In the past, due to the limitation of the development of technical condition...
