Abstract
A combustor is disclosed capable of averting engine flameout. This combustor comprises a combustion chamber, which comprises an outlet for discharging heated combustion products. The combustor further comprises a primary injector for injecting a fuel and compressed air into a primary zone of the combustion chamber such that the fuel is induced into a recirculation zone at a corner of the primary zone. Combustion means for combusting the fuel and the compressed air in the combustion chamber resulting in heated combustion products are also incorporated in the combustor. Moreover, the combustor comprises sensing means for monitoring the combustor to substantially detect a pre-flameout condition. To realize the advantages of the present invention, the combustor additionally comprises a pilot injector for injecting a propellant into the recirculation zone in response to detecting said flameout condition by the sensing means, such that the propellant combusts as a diffusion flame.
