Embodiment Construction

[0031] The present invention mainly relates to the connecting device between the door 14 of the aircraft cockpit and the fixed part 20, which can restrict the mutual movement between the two in the longitudinal direction, and the longitudinal direction basically corresponds to the main air flow outside the cabin during flight. direction.

[0032] The connecting device includes, on the one hand, a male element connected to the door and also called a locator or knife 40, and on the other hand, a female part 42 whose shape can fix the male element 40 and restrict relative movement in the direction of air flow. . The advantage is that the shape of the female part enables relative rotation between the two elements around the longitudinal axis of the cabin.

[0033] In a variant, it can be considered that the male element is connected to the fixed part and the female part is connected to the door.

[0034] To make the description simple, the door 14 has a shape of a plate 44, wherein the...

Abstract

The invention relates to a fuse link device between a mobile part and a fixed part of an aircraft nacelle. The object of the invention is an aircraft nacelle that comprises at least one part, called a door (14), that moves relative to a stationary part (20) and a connecting device that makes it possible to limit the offset between said door and said stationary part in a direction that corresponds to the primary direction of the flow of air outside of the nacelle during flight, whereby said device comprises, on the one hand, an indexer (40) that is connected to the door (14) that comprises an attachment surface (63) and at least one attachment element (66), and, on the other hand, at least one stop (58) that is connected to the stationary part (20) against which said indexer (40) can rest in such a way as to limit its movement in said direction, characterized in that said at least one attachment element (66), oriented in the radial direction, is arranged upstream from the stop (58) in said direction, said at least one stop (58) comprising a surface relative to the door arranged essentially at the attachment surface (63) of the indexer (40).

Description

Technical field [0001] The invention relates to a fusible connection device between a movable part and a fixed part of an aircraft cockpit, especially between the door of the cockpit and the remaining parts in the cockpit. Background technique [0002] Such as figure 1 with figure 2 As shown, the mechanical parts of the aircraft are integrated into a structure referred to below as the cockpit 10, and the cockpit is connected to the aircraft with a connecting device, in particular, a rod 12 is used to connect it to the sail. [0003] The cockpit has many functions, among which the main functions are: in order to optimize the aerodynamic fluid, adjust and control the air movement around and in the motor; protect the motor of external components; reduce noise hazards; enable internal air circulation; participate in the motor machinery Force distribution; support the thrust reversal system if possible. [0004] Finally, the cockpit should be able to perform routine maintenance and repa...
