Problems solved by technology

However, the "close coupling" between the fuel and the stabilizer will reduce the combustion intensity of the recirculation, significantly increase the combustion vibration, and when the equivalence ratio is too high, it is easy to cause flameout due to local fuel shortage in the recirculation area

Abstract

The pneumatic auxiliary integrated support plate stabilizer comprises a shell, an air supply pipe, an internal oil supply pipe and a wall surface oil supply pipe, the air supply pipe is fixed on the upper wall surface and penetrates through the upper wall surface to extend into the cavity; a plurality of air supply holes facing the rear edge plate are formed in the air supply pipe in the cavity; the internal oil supply pipe is fixed on the upper wall surface, is distributed parallel to the air supply pipe, and penetrates through the upper wall surface to extend into the cavity; a plurality of direct injection type oil supply spray holes which are opposite in pairs and face the side wall surface of the U-shaped stabilizer main body are formed in the inner oil supply pipe in the cavity; the wall surface oil supply pipe is fixed on the upper wall surface, is parallel to the internal oil supply pipe, and penetrates through the upper wall surface to extend into the cavity; a wall surface oil supply pipe in the cavity is connected with the side wall surface of the U-shaped stabilizer main body; and a plurality of correspondingly through wall surface oil supply spray holes are formed in the side wall surface of the U-shaped stabilizer main body and the wall surface oil supply pipe. The flow loss can be reduced, and the stable working capacity of the flame stabilizer is improved.

Description

Technical field [0001] The present invention relates to the field of power devices, involving an integrated flame stabilizer used in a multi-modal combustion chamber, a sub-combustor combustion chamber, a bimble firing engine combustion chamber, a scroll / stamped combination cycle engine, and a double oil passage. Pneumatic auxiliary integrated branch stabilizer for oil supply. Background technique [0002] The aggressive combustion chamber is an application in the case of a large thrust in the air engine, which is capable of sacrificing the fuel as a consumer in the case of aircraft, climbing, or other short time to sacrifice fuel as a cost, greatly increasing the engine thrust. With the development of engine technology, the weight is getting higher and higher, and the turbine outlet temperature and Mach are gradually increased. This will increase the risk of fuel injection rods, resulting in spontaneous combustion of the new generation of aggressive combustion chambers. Featur...
