Problems solved by technology

In this regard, its disadvantage is that, due to the oscillating bracket, an undesired couple of forces can arise between the normal force acting on the flap and the driving force which depends on the relative displacement of the main spar
In addition, due to the required components (main beams, swing brackets, bearings, etc.)

Embodiment Construction

[0032] figure 1 Shown is a perspective view of a modern passenger or transport aircraft equipped with a high lift system at the leading edge of the main wing and at the trailing edge of the main wing of its wings to increase lift during take-off and landing. On each side at the trailing edge of the wing 1 are provided a plurality of high-lift flaps 2 which are coupled to a central flap drive 20 via a torsion shaft system 30 comprising a plurality of torsion shafts. like Figure 4 Schematically shown in FIG. 2 , the flaps 2 are connected to the wing 1 in a movable and adjustable manner at various transmission points 3 , 4 , 5 and are held spanwise as well as chordwise.

[0033] figure 2 For schematic illustration, the figure shows a cross-sectional view through an adjustment device according to a first embodiment of the present invention. A high-lift flap (landing flap) 102 is provided at the trailing edge of the aircraft wing 1, and in the embodiment shown, the adjustment ...

Abstract

Adjusting device for adjusting a high-lift flap (2; 102) and airfoil wing provided with the same, comprising at lest one flap drive (20) for operating the flap (2; 102), and comprising several drive stations (3, 4, 5) which movably connect the high-lift flap (2; 102) to the airfoil wing (1) for guiding the flap (2; 102) by means of tension / compression elements (7; 107), the flap drive (20) being connected to several drive stations (3, 4, 5) for adjusting the high-lift flap (2; 102). According to the invention, at least one compensation element (10; 110) is provided at least at one drive station (4) for compensation of constraining forces occurring in the drive links comprising the tension / compression elements (7; 107) due to relative movements in wing chord direction between the flap (2; 102) and the wing (1).

Description

technical field [0001] The present invention relates to an adjustment device for adjusting a high-lift flap located at the wing of an aircraft as claimed in the preamble of claim 1 and to an aircraft including such an adjustment device as claimed in claim 22 wing. Background technique [0002] In the known high-lift systems of modern passenger and transport aircraft, and in particular of aircraft with high take-off weights, the high-lift flaps provided at the trailing edge of the main wing are moved in a movable manner by means of a plurality of transmission points. connected to the wing. In order to operate the flaps, a drive link is used which comprises a tension-compression element (transmission rod), which is connected, for example, via a torsion shaft to a flap drive which is usually arranged in a central position. The tension-compression element is coupled to a lever arm arranged on the torsion shaft and to the flap in the region of the transmission point via a load-...
