Abstract

The invention provides a liquid rocket electric pump engine ground test system. The system comprises a fuel supply system, an oxidizing agent supply system, an electric pump pressure type engine system, a power supply and a control system. The fuel supply system and the oxidizing agent supply system are connected with the electric pump pressure type engine system through a first pipeline and a second pipeline respectively, and pressurization and supply of fuel and an oxidizing agent are achieved through a fuel pump and an oxidizing agent pump. Start and stop of the fuel pump and the oxidizingagent pump are controlled through a motor driver in the power supply and the control system to achieve start and stop performance of the electric pump pressure type engine system. The system is suitable for an electric pump pressure type liquid rocket engine, and particularly has remarkable application advantages in the aspect of testing of a variable-thrust and multi-start liquid rocket engine.

Description

technical field [0001] The invention relates to the technical field of pump-pressed liquid rocket engines, in particular to a ground test system for electric pump engines of liquid rockets. In particular, it relates to an electric pump engine ground test system. Background technique [0002] The existing pressurization methods of liquid rocket engines mainly include squeeze type and turbo pump type. Although the concept of electric supercharging has been proposed long ago, it was limited by the technology of electric motors and high-performance batteries. Until recently, it has not developed rapidly in foreign countries. Compared with the conventional extrusion or turbo pump pressure supply system, the electric pump booster system has the advantages of higher engine inlet pressure, variable operating conditions through speed control, and easy realization of multiple engine start-ups. Liquid rocket electric pump engine ground test system: 1) It is convenient to adjust the w...
