Abstract

Official abstract text for this publication.

A propulsion system for an aircraft. The propulsion system comprises a core, an internal fixed structure secured to the core and arranged around the core, and a nacelle surrounding the core and the internal fixed structure in which a secondary flow path is delimited between the internal fixed structure and the nacelle. The internal fixed structure has a slot which permits fluidic communication between a compartment on the inside of the internal fixed structure and the secondary flow path.

First claim

Opening claim text (preview).

The invention claimed is: 1. A propulsion system for an aircraft, the propulsion system comprising: a core, an internal fixed structure secured to the core and arranged around the core, and a nacelle surrounding the core and the internal fixed structure, in which a secondary flow path is delimited between the internal fixed structure and the nacelle, wherein the internal fixed structure has a slot which permits fluidic communication between the secondary flow path and a compartment defined between the internal fixed structure and the core, wherein the internal fixed structure comprises a front panel arranged forward the slot and a rear panel arranged aft of the slot, wherein the slot is defined by a gap between the front panel and the rear panel, wherein spacers, arranged across the slot are fixed to the front panel and to the rear panel, wherein the front panel comprises an interior wall radially inward of an exterior wall, wherein, at a rear end of the front panel, the interior wall comprises an inclined plane which extends to the exterior wall, wherein the rear panel is formed by a single wall and comprises a front part, a rear part and a bend which connects the rear part and the front part, wherein the front part is radially inward and axially forward of the rear part; and wherein the spacers are fixed between the rear end of the front panel and the front part of the rear panel. 2. The propulsion system according to claim 1 , further comprising a plurality of stiffeners, each stiffener being fixed in the compartment to the interior wall and to the rear panel. 3. The propulsion system according to claim 1 , wherein the exterior wall comprises a front plate extending forward from a junction zone and a rear plate extending aftward from the junction zone to the rear end. 4. The aircraft comprising the propulsion system according to claim 1 .
