FUEL INJECTOR FOR REDUCING COMBUSTION INSTABILITY, FLIGHT VEHICLE HAVING THE SAME AND CONTROL METHOD OF FUEL INJECTION

摘要

PURPOSE: A fuel injection device for reducing instable combustion, an aerial vehicle having the same, and a fuel injection control method are provided to stabilize combustion in a recirculation area and to relieve or prevent the vibration of a combustion flame. CONSTITUTION: A fuel injection device for reducing instable combustion comprises: a fuel injection unit(141) producing an air fuel mixture(151) by mixing fuel with influent air, and injecting the air fuel mixture; a flame stabilization unit(142) arranged on an injection path of the air fuel mixture to form a recirculation area of the air fuel mixture to stabilize a combustion flame of the air fuel mixture; and a secondary fuel injection unit injecting secondary fuel to the recirculation area to reduce the vibration of the combustion flame.
