An assembly for a turbomachine optimizes air flow near the exhaust cone which has an outer annular wall for the flow of a primary air flow and an inner annular wall arranged inside the outer annular wall, a metal casing arranged upstream of the exhaust cone, a shroud defining a radially inner face with respect to the primary air flow, and a metal connecting flange interposed longitudinally between the inner annular wall and the metal casing and connecting the inner annular wall and said metal casing. The assembly includes at least one bolt which passes through the outer annular wall and the annular portion of the connecting flange, a nut screwed onto the bolt and arranged radially inside the annular portion of the connecting flange, and at least one spacer which has a coefficient of expansion that is greater than the coefficient of expansion of the metal casing.

An aircraft propulsion assembly has a hinge for articulating a first and a second of its panels. The hinge includes a yoke rigidly connected to the first panel and a counter-yoke rigidly connected to the second panel, which is received between two lugs of the yoke. The yoke and the counter-yoke are passed through by a hinge pin that is movable between an extended position between the lugs of the yoke and a retracted position outside the yoke. The hinge further includes bayonet mounting means interposed between the pin and the yoke.

Hinge for articulating two panels of an aircraft propulsion assembly

The present invention relates to an assembly for a turbomachine turbine extending along an axis (X), comprising: —an ejection cone () comprising a radially outer annular wall () defining a flow duct for a flow of hot gases and a sound box radially arranged inside the outer annular wall (), the sound box comprising a radially inner annular wall (), —a connecting member () intended to be axially inserted between the exhaust housing and the ejection cone (), the connecting member () comprising an upstream annular flange () intended to be attached to the exhaust housing and a plurality of downstream securing tabs () connected to the inner annular wall (), —an annular sealing shroud () comprising an upstream portion surrounding the securing tabs () of the connecting member () so as to cover the spaces circumferentially located between the securing tabs () and axially located between the upstream annular flange () of the connecting member () and the radially inner annular wall ().
