Invisible structure suitable for strong infrared inhibition effect of binary thrust vectoring nozzle

The invention belongs to the technical field of engine nozzle design, and particularly relates to an invisible structure suitable for a strong infrared inhibition effect of a binary thrust vectoring nozzle. The invisible structure mainly comprises a nozzle body, the nozzle body is of a cylinder structure, a main flow channel is defined by an upper adjusting piece, a lower adjusting piece, a left sidewall and a right sidewall, the wall faces of the cylinder structure are double-layer walls composed of inner walls and outer walls, a gas collecting cavity is formed between the inner walls and the outer walls, the gas collecting cavity comprises a gas source cavity, an aerosol storage cavity and a spraying cavity, baffles are arranged between the gas source cavity and the aerosol storage cavity and between the aerosol storage cavity and the spraying cavity, a plurality of via holes are formed in the baffles, and a plurality of spraying holes are formed in the rear end of the gas collecting cavity.
