Double-outlet S-shaped spraying pipe capable of reducing infrared radiation signals and control method thereof

摘要: The invention discloses a double-outlet S-shaped spraying pipe capable of reducing infrared radiation signals. comprises an air feeding and shunting section, wherein outlet the section is divided into two parts symmetrical structure; successively connected with circular-torque-shaped rectangular sections, film cooling exhaust converging sections expansion respectively; side wall inner each connection cold chamber; holes in dislocation arrangement are formed between chamber. also control method pipe. Through method, detector incapable directly detecting high-temperature components behind engine turbine; emitted by at upstream can be shielded to maximum extent; meanwhile, temperature reduced, so that signals greatly performance improved.
