摘要： The invention relates to a prestressing device (10) extending about an axis (A) between a first plane that is substantially perpendicular to the axis (A) and a second plane that is substantially parallel to the first plane and axially offset relative to the latter. The device includes a first annular body (13) extending in the first plane, and a first series of at least three tabs (15), each of which is connected to the first body and extending in an essentially radial direction, each of the tabs of the first series including a planar surface (17) extending in the second plane. This arrangement ensures surface contact between the parts of the elements to be subjected to prestressing. The device can be used in particular for a rotor, and especially for a rotor of an unducted propeller for a turbine engine.

摘要： Unshrouded fan with variable-pitch blades the roots (38) of which are each fitted from the outside into a radial housing of an annular rotor element and guided in rotation about their axis by two rolling bearings (76, 94), one of which is borne by an annular segment (54) with cylindrical skirt (56) mounted in a groove (50) of the cylindrical body (40) and by a locking nut (64) screwed onto the cylindrical skirt (56). Said bearing (94) is externally capped by a ring (100) that has external dog teeth (108) engaging with internal dog teeth (112) of the housing to provide axial retention for the ring (100) in the housing. Locking means inserted between the teeth (112) of the housing and those of the ring (100) prevent the ring (100) from turning or from being removed axially from the housing.

摘要： The invention relates to a turbine engine compressor, including a first housing (28a) for supporting the injectors, a second housing (28b) arranged around the first housing while forming an annular space (40) therewith, and a plurality of air injectors (38), each mounted in recesses. Each air injector has at least one inner air injection channel (48) which leads, on one side, into an outflow jet (26) of the gas stream and, on the other side, into the space formed between the housings, and, at an upstream end, an upstream rim (52) having an inner surface (52a) radially abutting against an upstream rim (44) of the corresponding recess of the first housing and an outer surface (52b) radially abutting against an inner surface of the second housing. A means for clamping the upstream rim of the air injectors between the housings enables the air injectors to be held in position in the recesses of the first housing.
