Embodiment Construction

[0012] Hereinafter, a description of preferred embodiments of the present invention will be provided in detail with reference to the accompanying drawings.

[0013] figure 1 A schematic structural diagram of a spoiler in an embodiment of the present invention is shown. The spoiler 1 is made of the same material as the door inner skin 4 (such as 7075-O). The width and thickness of the spoiler 1 are basically the same as those of the door inner skin 4 . In order to ensure the connection strength, the spoiler 1 has a notch adapted to the shape of the maintenance cover 2 on the side close to the maintenance cover 2 on the inner skin 4 of the cabin door, so as to reserve the installation space for the maintenance cover. In this embodiment, the notch is in the shape of an open opening and surrounds part of the periphery of the maintenance access cover 2 . It can be understood that, in other embodiments, the notch can also be in the form of a closed opening, so that it surrounds t...

Abstract

The present invention provides a spoiler for a hatch door on an aeroplane, which spoiler is installed on the inner covering of the hatch door, inside the wind-facing leading edges of the front hatch door on the left and right of the front landing gear of the aeroplane, and is tightly assembled with the inner covering of the hatch door, so as to reduce the force required to open the hatch door. The present invention also provides a hatch door on an aeroplane, which hatch door has the spoiler for a hatch door on an aeroplane of the present invention installed on the inner covering thereof. The spoiler according to the present invention can effectively reduce the force required to open the hatch door, requires little modification to the original mechanism, and is convenient to install and maintain.

Description

technical field [0001] The invention relates to a part used on an aircraft door, in particular to a spoiler used for an aircraft door and an aircraft door equipped with the spoiler. Background technique [0002] In the design of the aircraft nose landing gear retraction system, its wind resistance and gravity are relatively obvious load factors, because they often help to lower and prevent retraction, so the focus of analysis and design is always on the retraction rather than the lowering process , which will cause unexpected situations during the lowering of the nose landing gear of some models. This type of landing gear is mainly a structural configuration in which the nose lift door and the upright are linked, and there is no separate nose lift door drive device. This configuration is complex in structure, but the control is simple and does not require a separate nose door control system. Due to the linkage relationship, when the mechanism is designed, in order to avoid ...
