ASSEMBLY FOR AN EXHAUST CONE IN A TURBOMACHINE NOZZLE

Abstract: 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.
