A spacer ( ) made to be installed between two permanently connected discs ( and ), without a bolted flange, and comprising axial thrust ( ) as well as outer radial thrust ( ) alignment surfaces ( ). It comprises moreover an outer cover ( ) to provide sealing and a cooling passageway, and stiffening tongues ( ) which accommodate thrust loads.

Turbomachine rotor assembly with two bladed-discs separated by a spacer

A bypass gas turbine engine having an intermediate structural casing positioned between a primary flow path and a bypass flow path, and configured between a low pressure compressor and a high pressure compressor. The engine further having a bleed device arranged to deflect a portion of a gas flow from the low pressure compressor toward the bypass flow path. The bleed device includes an annular cavity defining a manifold situated upstream the intermediate casing and opening along the outer wall of the primary flow path, a plurality of conduits positioned along the intermediate casing, a plurality of tubes configured around the high pressure compressor and connecting the conduits to the bypass flow path, and at least one flow regulating valve disposed along the interior of each of the plurality of tubes.

Bleed system driven in simplified manner for a turbojet or turboprop engine

Aircraft engine, whose ancillary equipment forms a unitary assembly wherein the equipment is located to the rear of the air intake duct in a substantially closed central compartment just upstream of the gas generator. The equipment positioned along the engine axis, which, inter alia, leads to low engine drag in operation.
