Abstract

The object of the invention is an aircraft nacelle that comprises, on the inside, an inside pipe (56) that empties out toward the front at an air intake (58), and, on the outside, an aerodynamic wall that extends from the air intake (58) up to the rear end of the nacelle, and a hood (62) that comprises said air intake (58) as well as a cylindrical wall (64) that forms at least one portion of the aerodynamic surface of the outside of the nacelle, whereby said hood (62) can move translationally relative to a stationary part of the nacelle toward the front along slides (72), each slide (72) comprising a guide element (74) that is connected to the hood (or to the stationary part of the nacelle), whereby said guide element (74) can slide into a pipe (78) that is connected to the stationary part of the nacelle (or to a hood) and has a section that is above the section of the guide element (74) so as to allow the hood (62) to rotate in order to immobilize it in the closed position.

Dependent claims

An aircraft nacelle, comprising:

aerodynamic surface of an outside of the nacelle;
an air intake (58);
on an inside of the nacelle, an inside pipe (56) emptying out toward a front at the air intake (58);
on an outside of the nacelle, an aerodynamic wall extending from the air intake (58) up to a rear end of the nacelle;
and
a hood (62) comprised of said air intake (58) and a cylindrical wall (64) that forms at least one portion of the aerodynamic surface of the outside of the nacelle;
a stationary part;
slides (72), each slide (72) comprising a guide element (74) connected by a connecting part (82) to the hood and a conduct (78) connected to the stationary part,
said guide element (74) having a rectilinear bar shape with a cylindrical section that can slide into the conduct (78) of the sliding element (76) that is connected to the stationary part;
wherein said hood (62) is movable translationally, relative to the stationary part, toward a front of the nacelle along the slides (72),
wherein the conduct (78) has an oblong section with a width essentially equal to a diameter of the bar and a length allowing a rotation of the hood (62) to immobilize the hood in the closed state,
wherein the sliding element (76) has a slot (80) extending parallel to the guide element (74), said slot (80) being positioned so as not to allow passage of the connecting part (82) and the translation of the hood (62) when the hood (62) is in the closed state,
wherein the connecting part (82) is arranged to the right of the slot when the hood has pivoted and allows the translational movement of said hood, said slot (80) having a width suited to the connecting part (82) so as not to allow the rotation of the hood (62) when the hood is not in the closed state.

An aircraft nacelle, comprising:

an air intake;
on an inside of the nacelle, an inside pipe (56) emptying out toward a front at the air intake (58),
on the outside of the nacelle, an aerodynamic wall that extends from the air intake (58) up to a rear end of the nacelle,
a hood (62) comprised of said air intake (58) and a cylindrical wall (64) forming at least one portion of an aerodynamic surface of the outside of the nacelle,
wherein said hood (62) is movable translationally relative to a stationary part of the nacelle toward the front along slides (72), each slide (72) comprising a guide element (74) connected by connecting means (82) to the stationary part of the nacelle,
wherein said guide element (74) has a rectilinear bar shape with a cylindrical section and is slideable into a conduct (78) of a sliding element (76) s connected to the hood,
wherein the conduct (78) has an oblong section with a width essentially equal to a diameter of the bar and a length allowing a rotation of the hood (62) to immobilize the hood in the closed state,
wherein the sliding element (78) has a slot (80) that extends parallel to the guide element (74), said slot (80) being positioned so as not to allow the passage of the connecting means (82) and the translation of the hood (62) when the hood (62) is in the closed state,
wherein the connecting means (82) is arranged to the right of the slot when the hood has pivoted to permit the translational movement of said hood, said slot (80) having a width relative the connecting means (82) so as not to allow the rotation of the hood (62) when the hood is not in the closed state.
