Embodiment Construction

[0032] The present invention will be further described below with reference to the accompanying drawings.

[0033] like Figure 1-3 As shown in the figure, the afterburner provided by the present invention, which integrates the mixer and the support plate stabilizer, includes an afterburner cylinder 1, a rear ducted ejector 3, and a support plate stabilizer 4, which are arranged coaxially from the inside to the outside. and center cone 5. An outer duct is formed between the afterburner cylinder 1 and the rear duct ejector 3 . An inner channel is formed between the rear bypass ejector 3 and the central cone 5 . One end of the support plate stabilizer 4 is connected with the rear duct ejector 3 , and the other end is connected with the center cone 5 . A heat shield 2 is also arranged between the forcing cylinder 1 and the support plate stabilizer 4 . Gap, which is used for the passage of extraneous airflow.

[0034] like Figure 4As shown, there are a plurality of support ...

Abstract

In order to solve the problems that according to an existing afterburner integrated design scheme, a backflow area and a combustion area move forwards, consequently, combustion is insufficient, and the difficulty of ignition and flame stabilization is increased, the invention provides a supporting plate stabilizer with a gas mixing function and an integrated afterburner. The two symmetrical open type concave cavities are formed in the middle of the supporting plate stabilizer, the open type concave cavities have the gas mixing function and can replace a mixer in a traditional afterburner, and the structure of the afterburner is simplified; in addition, due to the fact that the oxygen content of the outer culvert air flow is higher than that of the inner culvert air flow, the oxygen content of the mixed air is increased after the outer culvert air flow and the inner culvert air flow are mixed, the outer culvert air flow and the inner culvert air flow are combusted while being mixed, and the combustion efficiency is improved. Therefore, combustion is more sufficient, and flame stability and combustion efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to a strut stabilizer with an air mixing function and an integrated afterburner. Background technique [0002] The afterburner has been developed for about 80 years. Although the mass of the afterburner accounts for about 20% of the engine, it can greatly improve the thrust. Generally speaking, the thrust of the turbojet engine can be increased by 40% to 50% after the afterburner is turned on, and the thrust of the turbofan engine can even be increased by more than 70%. The increase in thrust brings about the improvement of flight maneuverability and the expansion of the flight envelope. Therefore, the development of afterburner is very important for military fighters. The flame stabilizer in the traditional afterburner is directly installed in the main flow, and the airflow flows through the flame stabilizer, forming a recirculation zone behind it, which is used to organize combus...
