Abstract

The invention discloses a hydrogen peroxide kerosene variable working condition thrust chamber adopting a syringe injector. The hydrogen peroxide kerosene variable working condition thrust chamber adopting the syringe injector comprises an injection chamber, a catalytic chamber and a combustion chamber which are sequentially connected from top to bottom, and further comprises the injector, whereinthe injector is coaxially arranged in the injection chamber, the catalytic chamber and the combustion chamber in the axial direction, and the injection end of the injector is located in the combustion chamber; and the injection end of the injector is provided with a kerosene injection port with an adjustable opening size, and the kerosene injection port is used for injecting kerosene fuel into the combustion chamber and mixing and combusting with the decomposed hydrogen peroxide fuel. Through the characteristic that the high-temperature gas subjected to hydrogen peroxide catalysis is self-ignited after being in contact with the kerosene, the ignition structure is simplified.

Description

technical field [0001] The invention belongs to the technical field of liquid rocket engines, and in particular relates to a hydrogen peroxide kerosene variable-condition thrust chamber adopting a pintle injector. Background technique [0002] The liquid rocket engine is an important foundation of the current launch vehicle, which is of great significance for space launch and deep space exploration missions. In order to further reduce the launch cost and increase the launch frequency, new requirements are put forward for the reuse and convenience of the rocket motor. Hydrogen peroxide and kerosene, as a pair of non-toxic propellants at room temperature, have the characteristics of high-density specific impulse and easy storage, which can bring convenience in storage and filling, and greatly reduce the launch preparation time; hydrogen peroxide is catalyzed Afterwards, it can be used as a working medium to drive the turbo pump to run. The entire cycle is relatively simple, a...
