Abstract

The invention discloses a mobile test platform for low-thrust rocket engines. The mobile test platform comprises a mobile platform, a running support, a propellant feeding system and a gas distribution system. The running support, the propellant feeding system and the gas distribution system are integrally mounted on the mobile platform. The mobile platform comprises a testing rack mounting structure, wheels, a load-carrying structure, an inner cavity and a gas distribution panel. The testing rack comprises a motionless support, plate springs, a movable support, an engine support, a thrust support and a thrust sensor. The propellant feeding system comprises a fuel supply system and an oxidant supply system. The gas distribution system comprises a high-pressure gas tank, a pressurizing gas pipeline and a blowdown gas pipeline. All system components are integrated on one mobile platform, so that the mobile test platform has the advantages of miniaturization, portability and the like.

Description

technical field [0001] The invention relates to a small-thrust rocket engine mobile test platform, which belongs to the technical field of liquid rocket engines. Background technique [0002] The power system of space vehicles such as artificial satellites and spacecraft generally needs to complete tasks such as orbit change, orbit maintenance, rendezvous and docking, attitude control box and precise positioning. Small-thrust rocket engines could power these missions. The small-thrust rocket engine is also used in the start-up guarantee system of the main engine, the protection spacecraft system in case of an accident when the rocket takes off, and the soft landing system. Therefore, experimental research on small-thrust rocket engines is being carried out extensively. [0003] Engine test is an important part of engine development, also known as engine test run. The test run is carried out on a variety of specially built test benches, that is, the engine or its assembly ...
