Embodiment Construction

[0034] figure 1 An example of a nacelle component of a jet engine according to the invention is shown, here in the form of a grid-type thrust reverser device 1 .

[0035] In a known manner (not described in detail below), the thrust reversal device 1 comprises, on the one hand, a grid arrangement (not shown) for deflecting a part of the flow of the jet engine (not shown) and, on the other hand, two A hood 2, which is translatable in the general longitudinal direction of the nacelle and can be alternately switched between a closed position, in which the hood 2 provides aerodynamic continuity to the nacelle and covers the steering grille arrangement, and an open position, in which , which opens the passage in the engine compartment and reveals the steering grille unit.

[0036] A supplementary blocking door (not shown) activated by a sliding movement of the hood 2 generally makes it possible to close the duct downstream of the grill arrangement, thereby optimizing the redirecti...

Abstract

The invention relates to an nacelle member (1) comprising at least one mobile cowling (2) pivotally or slidably mounted in an essentially longitudinal direction of the nacelle, capable of displacement between an expanded position and a closed position relative to a fixed structure of the nacelle member (1) through at least one pivoting or translation guiding sleeve (4, 7) that receives a guiding shaft (5, 6). An electric heating de-icing device (9, 13) is provided inside the guiding shaft or defines an interface between the guiding shaft (5, 6) and the guiding sleeve (4, 7).

Description

technical field [0001] This invention relates to nacelle components for jet engines, and more particularly to thrust reversers. Background technique [0002] The aircraft is propelled by several jet engines each housed in a nacelle housing a set of auxiliary actuating devices associated with its work and performing various functions when the jet engines are running or in standby. These auxiliary actuation means include in particular a mechanical system for actuating the thrust reversal means. [0003] A nacelle usually has a tubular structure that includes an air inlet upstream of the jet engine, a middle section intended to enclose the jet engine's fan, and a downstream section housing the thrust reverser and intended to enclose the jet engine's combustion chamber, the nacelle usually ending in For the discharge nozzle, the outlet of the nozzle is located downstream of the jet engine. [0004] A modern nacelle is used to house a dual-flow jet engine, or turbofan engine, w...
