FIELD: engines and pumps.
SUBSTANCE: proposed manifold of working gases generated by gas generator unit comprises channel and nozzle. Said channel forms vertical branch pipe comprising first section to direct gas flow toward vertical plane coming radially from aircraft axis and second section located behind said first section to direct gas flow radially to said axis. Nozzle axis is parallel with gas flow axis at gas generator outlet. Channel elements located ahead of aforesaid branch pipe are not seen from behind. Channel includes first cylindrical element, second element and two third elements. Every third element extends into one of semi-nozzles. Another invention of proposed set relates to method of operating above manifold including continuous bleeding of air from gas generator compressor to feed flow distribution means of each semi-nozzle. One more invention relates to gas turbine engine incorporating said exhaust manifold.
EFFECT: reduced infrared emission of gas turbine engine.
