Abstract
The invention relates to a nacelle rear assembly for a turbojet engine, that comprises: a hood, an inner structure in the shape of a sheath in which at least the rear portion (15) is of the O-duct type and is capable of axial sliding between an operational position in which it covers the gas generator (3) of said turbojet engine and defines an annular cold-air jet with said hood, and a maintenance position downstream from said operational position. The downstream portion (15) is conformed so as to be capable of sliding without blocking relative to said gas generator (3), and the inner structure includes an upstream portion (13) that can be separated from the downstream portion (15) and that includes at least two doors (13a, 13b) capable of opening towards the outside.
Claims12
A nacelle rear assembly for a turbojet engine comprising:
- a cowl,
- a pod-shaped internal structure of which at least a downstream part is of an O-duct type and is able to move in axial sliding between an operating position in which the downstream part covers the gas generator of said turbojet engine and defines an annular cold air flow path with said cowl, and a maintenance position situated downstream of said operating position, the upstream part of said internal structure being detachable from said downstream part and comprising at least two doors capable of opening outward,
- wherein an inside diameter of an upstream edge of said downstream part is greater than a largest diameter of said gas generator, so that this downstream part can slide without blockage in relation to this gas generator.
