Description
Technical Field
The utility model belongs to the technical field of the aircraft structure subassembly, in particular to aircraft wing bottom wall board.
Background
The civil aircraft is provided with a separating surface at the joint of the outer wing root and the central wing. The separation surface is generally provided with a key rib for butt joint of wings and a fuselage, the butt joint rib needs to transmit bending moment and torque of the outer wing, the axial directions of the upper and lower wall plates of the outer wing are transmitted to the upper and lower wall plates of the central wing through butt joint rib strips, and the torque forms shear flow and is transmitted to the fuselage through a butt joint rib web plate. Therefore, the butt joint rib is a hinge for connecting the fuselage and the wing, and is an important butt joint structure for connecting the outer wing and the central wing of the airplane, the region is complex in stress and large in load, and the design requirement of the wall plate butt joint structure of the butt joint rib meets the structural shape and has certain supporting strength.
Disclosure of Invention
An object of the utility model is to solve above-mentioned problem, provide aircraft wing end wall board.
In order to solve the above problem, the utility model discloses a technical scheme as follows:
wallboard at bottom of aircraft wing, a serial communication port, its main part includes the web, the floor, the reinforcing plate, the web includes first wallboard, the second wallboard, the third wallboard both sides are equipped with the flange respectively, the second wallboard level sets up, be equipped with the component on the second wallboard and set up the hole, the relative second wallboard of first wallboard sets up in the slant, the relative second wallboard of third wallboard sets up downwards to one side, the web both sides are equipped with the floor respectively, the floor sets up with the web is perpendicular, first wallboard and second wallboard junction, two components of second wallboard set up the jogged joint department, second wallboard and third wallboard junction do not are equipped with the reinforcing plate, the reinforcing plate transversely sets up.
Furthermore, the element arrangement hole is provided with an upward convex side edge, and the side edge is provided with a sealing strip clamping groove.
The utility model has the advantages that:
(1) the flanges are arranged on two sides of the second wall plate and two sides of the third wall plate respectively, the compressive strength of the second wall plate and the compressive strength of the third wall plate are enhanced through the flanges, and the second wall plate and the third wall plate are prevented from being bent.
(2) Ribs are arranged on two sides of the web respectively and are perpendicular to the web, and the rib strengthens the overall structural strength of the web and avoids the web from being torn and bent.
(3) First wallboard and second wallboard junction, two components of second wallboard set up the jogged joint department, second wallboard and third wallboard junction are equipped with the reinforcing plate respectively, and the reinforcing plate transversely sets up, and the reinforcing plate has strengthened the intensity of each junction, avoids it to take place to buckle.
(4) The component arrangement hole is provided with an upward protruding side edge, and the protruding side edge enhances the strength of the edge of the component arrangement hole so that the component arrangement hole is not torn.
