FIELD: engines and pumps.
SUBSTANCE: aircraft nozzle comprises rear side composed by stripes distributed along the nozzle edges and extra gas jets injectors. Every stripe extends backward between the front and rear transverse wings and has free edges oriented in the directions converging backward to define the streamlined rib. Said stripes produce the turbulent swirls at the nozzle jet boundaries. Extra jets are injected ahead of the free ends of the stripes into the jet injected by the nozzle through the bores arranged ahead of the front wing to exit ahead of the stripe front plane to initiate the turbulent swirling ahead of the stripe free ends. Another invention of proposed set covers gas turbine engine with above described nozzle.
EFFECT: reduced noise of turbojet stripe nozzle noise.
