Aircraft nacelle including a rear frame inclined to the rear

摘要

An aircraft nacelle includes a lip whose surface contacts with the aerodynamic streams extends inside the nacelle by an inside wall that delimits a layer that empties at a power plant and outside of the nacelle by an outside wall, a first front frame connects the inside and outside walls, delimiting an annular pipe with the lip, and a rear frame connects the inside and outside walls at a junction zone between the inside pipe and power plant pipe, for a given cross-section of the nacelle along a plane that contains the longitudinal axis of the nacelle, a point A at the intersection between the rear frame and the inside wall, and a point B at the intersection between the rear frame and the outside wall, with B being offset toward the rear of the nacelle relative to A over more than 50% of the rear frame's periphery.

主权项

1. An aircraft nacelle that comprises:
a lip; an inside wall that delimits an inside pipe; a surface of the lip that is in contact with aerodynamic streams extends inside the nacelle by the inside wall that delimits the inside pipe; a junction zone that connects the inside pipe to a pipe of a power plant outside of the nacelle by an outside wall; a front frame that connects the inside wall and the outside wall, delimiting an annular pipe with the lip; a rear frame that connects the outside wall and the inside wall at the junction zone between the inside pipe and the pipe of the power plant, the rear frame comprising at least one opening to link zones that are located on either side of the rear frame, each opening comprising at least one door that is articulated relative to an edge of the opening, whereby said door is able to occupy a first state in which the door blocks the opening and another state in which the door clears the opening; a point A corresponding to an intersection between the rear frame and the inside wall; and a point B corresponding to an intersection between the rear frame and the outside wall, wherein point A and point B lie in a plane that contains a longitudinal axis of the nacelle, wherein the point B is offset toward the rear of the nacelle relative to the point A over more than 50% of a periphery of the rear frame.
