Turbojet engine nacelle

摘要

A turbojet engine nacelle includes an air intake structure having a longitudinal outer panel incorporating an air intake lip, a middle structure to which the air intake structure is attached, at least one inner panel including an acoustic shroud, rails guiding the outer panel able to allow a rectilinear movement of the outer panel, and a reinforcing member to react the mechanical loads of the guide rails. In particular, the reinforcing member reacts the loads of the guide rails beyond a predetermined deformation of the guide rails.

1. A turbojet engine nacelle comprising:
an air intake structure to channel a flow of air towards a fan of the turbojet engine and comprising at least one longitudinal outer panel incorporating an air intake lip; a middle structure surrounding said fan and to which the air intake structure is attached in such a way as to provide aerodynamic continuity; at least one inner panel comprising an acoustic shroud, fixed at a downstream end to an upstream end of the middle structure forming therewith a fixed structure of the nacelle; means of guiding the outer panel(s) to allow a substantially rectilinear movement of the outer panel in the upstream direction of the nacelle so as to open the air intake structure; and reinforcing means to react mechanical loads of the guide means beyond a predetermined deformation thereof as the air intake structure opens, wherein said reinforcing means only reacts the mechanical loads when a deformation of the guide means occurs.
