Abstract

The invention belongs to an engine system and a thrust adjustment method thereof. In order to solve the technical problem that the existing open cycle liquid oxygen kerosene engine system does not have the thrust adjustment capability, cannot meet the multi-task requirements of a launch vehicle, and can realize a single function, a development method is provided. Type liquid oxygen kerosene engine system and its thrust adjustment method, the oxygen auxiliary circuit dual-position valve is set on the oxygen auxiliary line, and the fuel auxiliary line regulator is set on the fuel auxiliary line, which can pass through the oxygen auxiliary line double-position valve and the fuel auxiliary line. The road regulator adjusts the propellant flow and mixing ratio entering the gas generator, changes the temperature and flow of gas generated by the gas generator, thereby affecting the power of the turbine, and changes the propellant flow and pressure entering the thrust chamber to achieve a wide range of regulation Purpose of engine thrust.

Description

technical field [0001] The invention belongs to an engine system and a thrust adjustment method thereof, in particular to an open liquid oxygen kerosene engine system and a thrust adjustment method thereof. Background technique [0002] Conventional launch vehicles mostly use conventional propellant open-cycle engines. This type of engine system has a simple structure and is easy to use and maintain. However, the conventional propellants used are highly toxic and expensive, and are already facing the need for replacement. The new generation of launch vehicles mainly adopt liquid oxygen kerosene propellant afterburning cycle engines. This type of propellant has high specific impulse performance, low cost, convenient use and maintenance, and is non-toxic and pollution-free. high cost. [0003] The Chinese patent with the publication number CN111502864 discloses an open cycle liquid oxygen kerosene engine system and its use method. It uses a liquid oxygen kerosene propellant w...
