Abstract
A jet engine includes an inlet that takes air, and a combustor that burns fuel using the air. The combustor includes a fuel injector and an igniter for igniting a gas mixture of the air and the fuel. The igniter ignites and activates automatically by heat and pressure created by compression of the air that has been taken in through the inlet.
Claims14
A combustor in which fuel is burned using air taken through an inlet comprising:
- an igniter for igniting a gas mixture of the air and the fuel,
- wherein the igniter includes a solid fuel or an ignition explosive such that the solid fuel or the ignition explosive automatically catches fire due to heat and pressure created by compression of the air which has been taken through the inlet.
An operation method of a jet engine, the jet engine comprising:
- an inlet configured to take air;
- a combustor configured to generate combustion gas by burning fuel using the air;
- a nozzle configured to eject the combustion gas from a rearward side of the jet engine,
- wherein the combustor comprises an igniter for igniting a gas mixture of the air and the fuel,
- the operation method comprising:
- taking the air through the inlet, and autoigniting and activating the igniter using heat and pressure created by compression of the air which has been taken through the inlet;
- and
- emitting flame generated by igniting the igniter toward the gas mixture of the air and the fuel, and burning the gas mixture using the flame generated by igniting the igniter to start the jet engine.
