The invention provides an aircraft propulsion assembly comprising a gas generator coupled by a coupling mechanism to a thrust generator having a structural torque transmission gearbox, and a rigid cradle rigidly supporting firstly the thrust generator in a first suspension plane and secondly the gas generator in distinct second and third suspension planes, the cradle being for securing to a structural element of the aircraft via a vibration-filtering flexible connection.

Apparatus for supporting a nacelle of an aircraft engine is provided by the present disclosure. In one form, the apparatus includes a frame, a supporting structure extending from the frame, and a structure for attaching a nacelle, which is rotatably mounted on the supporting structure and can be rotated about a substantially horizontal axis.

Propulsion assembly comprising: an inner casing (13); an outer casing (3); an inter-duct casing (15) delimiting a primary duct (12) between the inner casing (13) and an outer wall (14), and a secondary duct (16) between the outer casing (3) and an outer wall (17); a fan capable of generating an air flow (24) circulating from downstream to upstream in the secondary duct (16); the assembly further comprising: at least one duct (27) for bleeding air from said flow (24), this bleed duct (27) comprising an inlet port (28) in the outer wall (17) and an outlet port (29) in the inner wall (14); an outer flap (30) movable between an open position and a closed position of the inlet port (28); an inner flap (31) movable between an open position and a closed position of the outlet port (29).

A nacelle includes a stationary support, a forward nacelle structure, a latch assembly and an aft nacelle structure. The stationary support extends circumferentially about an axial centerline. The forward nacelle structure is configured to translate axially along the centerline between an aft stowed position and a forward deployed position. The latch assembly is configured to secure an aft end portion of the forward nacelle structure to the stationary support where the forward nacelle structure is in the aft stowed position. The aft nacelle structure is configured to translate axially along the centerline between a forward stowed position and an aft deployed position. A forward end portion of the aft nacelle structure axially covers the aft end portion of the forward nacelle structure and the latch assembly where the forward nacelle structure is in the aft stowed position and the aft nacelle structure is in the forward stowed position.

In order to reduce the size of the attachment arrangement between an aircraft engine and its attachment device, an engine assembly is provided for which the primary structure of the attachment device includes a central box and two movable structural cowls. Further the arrangement for attaching the engine on the structure comprises a group of main ties laid out in a main transverse plane for absorbing forces crossing a front end of the movable structural cowls, this group comprising three main shearing pins radially oriented and distributed around a longitudinal axis of the engine, each pin crossing a first shearing orifice provided on a fitting secured to the hub of the intermediate case on the one hand, and a second shearing orifice provided on one of the movable cowls or on its connecting structure to the central box on the other hand.

A system for starting a gas turbine engine of an aircraft is provided. The system includes a pneumatic starter motor, a discrete starter valve switchable between an on-state and an off-state, and a controller operable to perform a starting sequence for the gas turbine engine. The starting sequence includes alternating on and off commands to an electromechanical device coupled to the discrete starter valve to achieve a partially open position of the discrete starter valve to control a flow from a starter air supply to the pneumatic starter motor to drive rotation of a starting spool of the gas turbine engine below an engine idle speed.
