Abstract: A thrust reverser for a turbojet aircraft nacelle includes a fixed structure, a movable structure and an actuator. The actuator extends along a main axis and is connected by a first connection to the fixed structure and by a second connection to the movable structure for the deployment of the movable structure between a direct jet position and a reverse jet position. The actuator is also connected to the fixed structure by a third connection arranged longitudinally between the first connection and the second connection. An axis of the third connection is radially eccentric from the main axis and the third connection allows a predetermined displacement of the actuator with respect to the fixed structure.

Abstract: The present invention relates to an assembly comprising a duct, preferably a turbine duct, and at least one segment formed of at least two rigid shells, each shell comprising at least one fixing orifice for fixing to the duct and at least one fixing element at least one boss per shell which boss is fixed to the duct and against which boss the shell rests, such that at least one orifice and one boss face one another, and that the fixing element passes through the orifice facing the boss and is fixed to the boss.

Abstract: The present invention relates to a device for inserting a balancing weight into a rotor of a turbine, that includes an external component and an internal component. The internal component is connected in a helical manner to the external component. The internal component delimits a chamber which has a first and a second opening, a lower surface which is provided with a sealing joint and a cap in order to close in a tight manner the first opening of the chamber. The connection between the external component and the internal component is helical, that is to say, the result of a threading operation. Therefore, the internal component can thus move in a coaxial manner with respect to the external component.

Abstract: A seal arrangement is installed between confronting co-planar portions of a low pressure steam turbine exhaust hood and a circular bulkhead that forms part of an exhaust duct structure of a steam turbine module. The seal arrangement forms a vacuum seal between the interior and exterior of the exhaust hood and comprises a flexible gasket in the form of an annular diaphragm. This diaphragm has a radially inner circumferential portion that seals with the bulkhead, a radially outer circumferential portion that seals with the exhaust hood, and a radially median resilient portion. Sealing is achieved by providing radially inner and outer clamping flanges operative to sealingly clamp inner and outer circumferential portions of the gasket to the bulkhead and the exhaust hood respectively.

Abstract: A steam exhaust device for a steam turbine module includes a steam exhaust duct having a steam diffuser and a steam exhaust bottom wall, the steam exhaust duct being delimited by a surface of the steam diffuser configured to guide steam and by a steam exhaust bottom wall. A rigid hub includes one of a circular and a semicircular shape, the steam diffuser being rigidly fixed on the rigid hub. A rigid fastening device is fixed on the rigid hub and configured to support the steam exhaust device on a rigid frame.
