FIELD: engines and pumps.
SUBSTANCE: aircraft turbojet engine comprises jet nozzle to eject gas jet stream or to combine two gas jet streams. Jet nozzle represents one or two outlet rings furnished with appliances to disturb one or both jet streams and are made up of at least one pair of channels to eject air jest at pressure. Aforesaid channels are open at jet nozzle outlet. Channels of each pair converge to form triangle of air jets interaction at their outlets. Note that the angle of channels convergence varies from 40° to 70°, but preferably makes about 60°.
EFFECT: reduced acoustic noise.
