Abstract

The invention discloses a reusable igniter for the rocket engine. The rocket engine comprises an outer electrode, an inner electrode and a conductive assembly; a combustion cavity used for containingan electric control solid propellant is formed between the outer electrode and the inner electrode; the outer electrode surrounds the periphery of the combustion cavity, and the inner electrode is inserted into the electric control solid propellant; the conductive assembly comprises an outer electrode conductive assembly and an inner electrode conductive assembly which are electrically connected with the outer electrode and the inner electrode; the outer electrode is provided with a nozzle communicated with the combustion chamber; the end, close to the nozzle, of the combustion cavity is provided with a communicating cavity, and the communicating cavity is not filled with the electric control solid propellant and used for enabling gas generated after the electric control solid propellant is ignited to flow towards the nozzle. The igniter provided can realize multi-time ignition, can be repeatedly used, and is controllable in ignition intensity.

Description

technical field

[0001] The invention relates to the technical field of engine ignition, in particular to a reusable igniter for a rocket engine. Background technique

[0002] The liquid ramjet rocket engine uses liquid fuel, which has the advantages of fast speed, high maneuverability trajectory, and long range. Electronically controlled solid propellants generally use oxidizers and binders with high oxygen content, which have the advantages of repeatable ignition, controllable burning rate, good environmental performance, safety and good economy, and can be widely used in commercial or military fields.

[0003] The ignition device is one of the key components of the liquid ramjet rocket engine, and its function is to ignite the fuel accurately and reliably so that it can be established and burn stably. However, organizing stable combustion in a high-speed airflow requires the completion of fuel injection, atomization, fuel-air mixing and combustion reactions in a short tim...
