Abstract: An air intake swirler for a turbomachine injection system includes an upstream wall and a downstream wall, both of revolution about an axis of the air intake swirler, and fins distributed about the axis and connecting the upstream wall to the downstream wall so as to delimit, between the upstream wall and the downstream wall, air inlet channels each having an inlet and an outlet. The swirler includes two aerodynamic deflectors that respectively extend the downstream walls radially outward and that have a concavity oriented upstream. The aerodynamic deflectors extend radially facing the respective inlets of the air inlet channels and thus make it possible to limit the loss of pressure of the air supplied to the air inlet channels.

Abstract: A diffuser-nozzle assembly for mounting at an outlet from a compressor in a turbomachine, the assembly including a nozzle including two substantially cylindrical walls, a radially inner wall and a radially outer wall that are connected together by radial vanes. The walls of the nozzle are extended downstream beyond the radial vanes and the radial spacing therebetween varies downstream from the vanes to be at a minimum substantially in register with the vanes and at a maximum between the vanes.

Abstract: A pneumatic low aspect ratio truck has a crown reinforcing structure 7. The crown reinforcing structure 7 has a first steel belt ply 9 between the at least one carcass ply 3 and the tread 5, a second steel belt ply 11 between the first belt ply 9 and the tread 5, a third steel belt ply 13 between the second steel belt ply 11 and the tread 5 and a fourth steel belt ply 15 between the third steel belt ply 13 and the tread 5. The crown reinforcing structure 7 additionally has at least one circumferential steel strip 17 between the second and the third belt plies 11, 13.

Abstract: The present invention is directed to a pneumatic tire 1, in particular a low aspect ratio super single truck tire 1. In accordance with the invention, the tire has a crown reinforcing structure with a first breaker 9 between a carcass ply 3 and a tread 5, as well as four further breakers 11, 13, 15, 17 comprising at least one pair of working breakers between the first breaker 9 and the tread 5, wherein the first breaker 9 is a split breaker comprising two circumferential strips 9 essentially adjacent to the shoulders of the tire, each strip having an axial width comprised between 50% and 70% of the half tread width.

Abstract: A compressor nozzle ring for an aircraft includes an inner shroud, an outer shroud and a multiplicity of blades extending from the inner shroud to the outer shroud. Each blade passes through the inner shroud and is attached to it with sealing cement containing an organic polymer adhesive. The adhesive is polyimide based.

Abstract: A device for controlling variable-pitch vanes in a turbomachine has rods each having at one end a finger for mounting in a control ring and at its other end an assembly orifice for mounting on a drive square of a vane, the axis of the vane being inclined relative to the axis of the finger of the rod, and the assembly orifice in the rod presenting a dimension in the longitudinal direction of the rod that is greater than that of the drive square, and co-operating therewith to define clearance that varies over the height of the drive square and of the orifice.

Abstract: Blades (3) extending radially from the inner shroud (1) to the outer shroud (2) are attached to the inner shroud by means of a sealing cement containing an organic polyimide-based polymer adhesive.
