Fitting for introducing high forces into a fuselage cell of an aircraft

Abstract

Disclosed is a fitting for introducing great loads into a fuselage cell of an aircraft, in particular those which emanate from undercarriage components or are introduced into them. The fitting has a shoulder plate for bearing against the inside of the skin of the fuselage cell for example over its full surface area. Arranged underneath the shoulder plate is a vertical lug shackle with a lug for introducing the loads, wherein the lug shackle is led to the outside through a clearance in the skin of the fuselage cell. At least one approximately upright fastening shackle is provided on the upper side of the shoulder plate for connecting the fitting to a frame web. According to the invention, the loads occurring are introduced into the frame, substantially “moment-free” in the region of a neutral fiber, so that the said frame is not exposed to any appreciable flexural stresses and can be of a more lightweight design. The frame becomes the load introducing instrument and distributes the loads uniformly into the skin of the fuselage cell. Radially acting loads are transferred from the shoulder plate directly into the skin of the fuselage cell by way of shearing.
