Controllable flame stabilizer, engine and aircraft

Abstract

The invention discloses a controllable flame stabilizer, an engine and an aircraft. The controllable flame stabilizer is installed in an engine combustion chamber and comprises a shell, an electric control fuel gas generator and a spray pipe are arranged in the shell, and the electric control fuel gas generator comprises a fuel-rich electric control solid propellant combustion chamber and an oxygen-rich electric control solid propellant combustion chamber; one end of the fuel-rich electronic control solid propellant combustion chamber and one end of the oxygen-rich electronic control solid propellant combustion chamber are respectively a fuel-rich storage cavity used for containing a fuel-rich electronic control solid propellant and an oxygen-rich electronic control solid propellant storage cavity used for containing an oxygen-rich electronic control solid propellant; and independently-controlled electric ignition mechanisms are respectively arranged in the fuel-rich electric control solid propellant combustion chamber and the oxygen-rich electric control solid propellant combustion chamber. The fuel-rich propellant and the oxygen-rich propellant can be ignited and combusted separately or simultaneously according to the flight working condition and the maneuvering requirement of the engine, so that the air-fuel ratio is kept in a better state, and the stable combustion boundary and the engine performance are improved.

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...
