Abstract

The invention relates to structure design of aircraft hatch doors, in particular to an integrated airstair. The integrated airstair comprises a left side plate, a right side plate and pedals which areall made of paper honeycomb sandwich plates; the left side plate and the right side plate are the same in shape and size, the outer edge of one side of each of the left side plate and the right sideplate is in a step shape, and the left side plate and the right side plate are parallel to each other and are arranged symmetrically; the multiple pedals are arranged between the left side plate and the right side plate and distributed in a bent shape, so that steps matched with the step-shaped outer edges of the left side plate and the right side plate in shape are constituted; connecting piecesmade of rigid polyamide foamed plastic are used for connecting the pedals, the left side plate and the right side plate; and a laying layer made of fiber prepreg is laid on the outer surface of an integrated structural part formed by the pedals, the left side plate and the right side plate. According to the integrated airstair, the connecting structure is higher in stability, under the premise ofmeeting the use strength requirement, the weight of a hatch door structure is greatly decreased, and the use economic efficiency of a hatch door is improved.

Description

technical field [0001] The invention relates to the structural design of an aircraft cabin door, in particular to an integral boarding ladder. Background technique [0002] The aircraft boarding ladder is an aircraft access device for boarding personnel to board and disembark from the aircraft. Most of the current aircraft boarding ladders, especially the door-ladder-integrated boarding-door boarding ladder, are made of metal structure, which greatly increases the weight of the boarding door structure; in addition, there are connections between the various parts of the boarding ladder. Unreasonable defects cause the boarding ladder to fail to meet the strength requirements. Contents of the invention [0003] The object of the present invention is to provide an integrated airstair to solve at least one problem existing in the existing airstairs. [0004] Technical scheme of the present invention is: [0005] An integrated boarding ladder, comprising: [0006] The left s...
