Abstract: A system for the axial retention of a holding ring for a bearing for guiding in rotation a rotary shaft of a turbomachine is disclosed. The system includes an annular bearing support and a bearing holding ring that is borne by the annular bearing support. The bearing holder ring includes an upstream ring configured to be brought into contact with the bearing support and a downstream ring that is elastically deformable. The bearing support has a first axial retention element, and the bearing holding ring has a second axial retention element. The first and second axial retention elements are configured to cooperate with one another to axially retain the bearing holding ring in the event of damage to the downstream ring.

Abstract: A turbomachine including an exhaust housing, including a plurality of arms, the space separating the arms defining openings in which there circulates a primary air flow of the turbomachine, at least one conduit, a) configured to collect a compressed air flow at one of the ends of same, b) the other end of the conduit being connected to at least one opening of the exhaust housing, so as to insert the collected air flow into the primary air flow, the collected air flow having, when inserted into the opening, a Mach number less than or equal to 0.5.

Abstract: A turbine stage for a turbine engine, the stage including a nozzle and a wheel mounted inside a sectorized ring carried by a casing. The nozzle is attached to the casing and is retained axially downstream by bearing against an annular split ring. Each ring sector includes at its upstream end a member of C-shaped section that is engaged on the casing rail and that holds the split ring radially. A radially inner wall of the C-shaped member of each ring sector extends inside the split ring over an entire axial dimension thereof and its upstream end portion is engaged in at least one recess of the nozzle.
