CONNECTION OF A WING TO A FUSELAGE OF AN AIRPLANE

摘要

The invention relates to a wing connection (12, 15) to a fuselage (1, 14) of an airplane, particularly of a high-wing airplane, having a plurality of double-jointed coupling members (8-11, 16-21). According to the invention, at least two z-coupling members (8, 11, 16, 17) running substantially parallel to a vertical axis of the airplane and at least two xz-coupling members (9, 10, 20, 21) are arranged in the area of two longitudinal edges (4, 5) of a fuselage recess (3), wherein the xz-coupling members (9, 10, 20, 21) are constructed parallel to a longitudinal axis (x) of the airplane for a first load maximum of a load in the case of a crash and also of a load during normal flight operation, and are constructed parallel to a vertical axis (z) of the airplane for a second load maximum of a load in the case of a crash and also of a load during normal flight operation. The xz-coupling members are capable of receiving force components parallel to the x-axis, that is, parallel to the longitudinal axis of the airplane, as well as force components which are parallel to the z-axis, such that separate z-coupling members for force components in the z direction are unnecessary, resulting in a potential weight savings. Moreover, in an alternative embodiment, predefined crumple zones (59) are provided in the plating (51, 52, 53) of the front xz-coupling members (9, 10, 20, 21, 40), said crumple zones allowing transmission of force in the case of a crash via the xz fuselage mounting (26, 41) and the xz wing mounting by means of an at least partial form fit between the two xz mountings (26, 27, 41, 42). An additional weight reduction is possible in this case due to a lighter design of the xz mountings (26, 27, 41, 42) and the bolts.
