Abstract

The invention discloses a small vertical thrust vector test bench, which comprises a flange adapter, a force measuring assembly, a base plate, a platform, a main thrust calibrating device and two sets of side thrust calibrating devices. The two lateral thrust calibration devices are perpendicular to each other, and can perform lateral force calibration at different vertical heights. The main thrust calibration device is equipped with several stations, which can realize the calibration of different three-dimensional space forces and three moments in cooperation with the side thrust calibration device, which is easier to operate. The invention has the advantages of simple structure, high natural frequency, high rigidity, main side thrust calibration function and high-precision dynamic and static measurement capability in a small range, and is especially applicable to the thrust vector test of long-term low-thrust solid thrusters based on micro-nano satellites .

Description

technical field [0001] The invention belongs to the field of thrust vector testing, and relates to a small vertical thrust vector testing platform, which is especially applied to the thrust vector testing of solid thrusters based on micro-nano satellites. Background technique [0002] With the rapid development of aerospace technology, the research and development of space technology is getting more and more in-depth. High-mobility micro-nano satellites have become an important force in the field of space confrontation, and have become an important direction for the strategic development of space in traditional aerospace powers. To meet the rapid and large-scale orbit change maneuver and rapid response deployment of micro-nano satellites in the space environment, micro-nano satellite propulsion technology is needed to support. The solid rocket thruster has the advantages of simple structure, few external interfaces, high working reliability, fast response capability, good ma...
