The present invention relates to a thrust orienting nozzle, shaped in such a way as to divide a principal propulsion gas flow coming from at least one gas generator into a first flow and a second flow for an ejection in a first half-nozzle and in a second half-nozzle and comprising at least one of following two piloting means: a means of dividing the principal flow into each of the two half-nozzles, and a means of orienting the thrust vector produced by each of the two half-nozzles. The invention applies in particular to the yaw control of an aircraft without a vertical tail unit.

Thrust orienting nozzle

A device for reducing the jet noise of a turbomachine, the turbomachine having a longitudinal axis and a substantially cylindrical nozzle extending along the longitudinal axis of the turbomachine, having a downstream end for mixing the flows of gas inside and outside the nozzle, the device comprising a plurality of corrugations disposed to extend the downstream end of the nozzle, and a plurality of notches disposed between pairs of successive corrugations in the plurality of corrugations, and the plurality of corrugations and the plurality of notches are symmetrical relative to at least one axis perpendicular to the longitudinal axis of the turbomachine so as to generate a dual counter-rotating effect between the gas flows.

Device for reducing the jet noise of a turbomachine

The present invention relates to a convergent-divergent turbojet nozzle () comprising driven divergent flaps (), follower divergent flaps () interposed between the driven flaps, and means () for supplying cooling air to the follower flaps (), said follower flaps () having a box structure and having lateral openings for delivering cooling air towards the inner face of said driven flaps (), in such a way as to limit the heating up of these flaps when the turbojet is in operation.
