A Thrust Vectoring Test Bench with Main Side Thrust Decoupling

Abstract

The invention discloses a thrust vector test bench for main side thrust decoupling, which comprises a double-flange short tube, a force measuring device, a circumferential limiting device, a base plate and N sets of lateral linear limiting devices. The center of the circumferential limit device is provided with a through hole, which is fixed on the top surface of the bottom plate. The flanged short tube is fixed on the top surface of the force measuring device and is used to transfer the thruster. N sets of lateral linear limiting devices are evenly arranged around the circumferential limiting device, and the top surface of the bottom plate is fixed, and the outer wall surface of the circumferential limiting device is fixedly connected with the lateral linear limiting device. The invention has the advantages of simple structure and convenient installation, and can perform three-dimensional force test in space, and at the same time achieve decoupling of the main side thrust, and achieve more accurate measurement of the thrust vector characteristic of the thruster.

Description

technical field [0001] The invention belongs to the field of thrust vector testing, and in particular relates to a thrust vector testing platform for decoupling main side force and thrust, and is particularly applied to the thrust vector testing of solid thrusters based on micro-nano satellites.
