FIELD: transport. ^ SUBSTANCE: invention relates to aircraft engineering, particularly, to device intended for reducing infrared emissions at turboprop engine outlet and to turboprop engine. Proposed device comprises tubular channel 6 extending downward from turboprop engine nozzle 5 to allow hot gases F to flow from nozzle 5. Besides, said device has tubular sleeve 8 to slide into said tubular channel 6 when hot gases F flow there through and to switch: from inner position whereat tubular sleeve 8 seats completely inside tubular channel 6 into extended position whereat said sleeve extends from said channel 6. ^ EFFECT: reduced infrared emission. ^ 10 cl, 7 dwg |
