摘要: The invention provides an ejection type infrared suppressor with double layer cooling mixed tubes. comprises the inner and outer tubes, a lobe nozzle hollow flow director slit. According to suppressor, upper lower asymmetric is adopted, so that high-temperature exhaust gas at each part can just attach thewall outlets of momentum utilized maximum extent, outside cold air guided as much possible; forced introduced into inlet double-layer tube, airflow flows through interlayer between wall surfaces tubes are cooled; tube slit diversion guide plate blended hot gas, temperature further reduced; in generates multiple streams plate, mixing uniformity andthe injection improved; be greatly reduced by adopting radiation intensity reduced.
