Structural nacelle

摘要

The present invention relates, on the one hand, to a nacelle (1) for a double flow turboreactor (2) comprising a front air intake section (5), a median section (6) intended for surrounding a fan (3) of the turboreactor and a rear section (7), said rear section having an internal structure (7b) intended for serving as a housing to a rear portion of the turboreactor, characterized in that the internal structure possesses attachment means suitable for enabling the nacelle to be fastened to a pylon (12) intended to be connected to a fixed structure (13) of an aeroplane on at least one portion of said internal structure, and on the other hand, to a propellant assembly and to an aircraft provided with such a nacelle.

主权项

1. A nacelle for a turbofan comprising
a front air intake section, a mid-section designed to surround a fan of a turbojet and a rear section, said rear section having an internal structure designed to serve as a casing to rear portion of the turbojet and an external structure, wherein the internal structure has coupling means suitable for allowing an attachment of the nacelle to a pylon designed to be connected to a fixed structure of an aircraft on at least one portion of said internal structure, wherein the internal structure comprises at least one external wall forming an aerodynamic surface adjacent a cold flow stream that flows between the internal structure and the external structure, the external wall mounted over a framework made from plurality of radial frames distributed over the length of the internal structure and each radial frame comprising a circumferential ring, wherein each adjacent circumferential ring is connected together by at least one reinforcement between them.
