Controllable flame holders, engines and aircraft

Abstract

A controllable flame stabilizer, an engine and an aircraft. The controllable flame stabilizer is installed in the combustion chamber of the engine. Controlled solid propellant combustion chamber, oxygen-enriched electronically controlled solid propellant combustion chamber; one end of the fuel-rich electronically controlled solid propellant combustion chamber and oxygen-enriched electronically controlled solid propellant combustion chamber is respectively a and the fuel-rich storage chamber of the oxygen-enriched electronically controlled solid propellant and the oxygen-enriched electronically controlled solid propellant storage chamber; the fuel-enriched electronically controlled solid propellant combustion chamber and the oxygen-enriched electronically controlled solid propellant combustion chamber are respectively equipped with independently controlled electrical ignition mechanism. According to the flight conditions and maneuvering requirements of the engine, the fuel-enriched propellant and the oxygen-enriched propellant can be ignited and burned separately or simultaneously to maintain the air-fuel ratio in a better state, thereby improving the stable combustion boundary and engine performance.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to a controllable flame stabilizer, an engine and an aircraft. Background technique [0002] Flame stabilizers are an important component of aero turbine engines and ramjet engines. In an aero turbine engine or a ramjet engine, due to the high speed of the incoming air, it is quite difficult to fully mix the fuel with the incoming air, to ignite and to burn stably, and even flameout occurs during the flight. In order to improve the combustion efficiency of the fuel in the combustion chamber of the ramjet engine and prevent the flame from quenching, a flame stabilizer is often installed in the combustion chamber in practical applications. The incoming air enters the combustion chamber through the intake port. In the combustion chamber, the high-speed incoming air reacts with gas or fuel, and the high-speed gas generated is ejected from the nozzle to generate thrust. [0003] In add...
