Problems solved by technology

[0005] However, this embodiment has the disadvantage that the outer frame has to be designed as a whole in a bendable manner in order to enable a geometrical adaptation
Furthermore, it is disadvantageous that the provision of separate actuators on the front and rear edges significantly increases the weight of the profile

Embodiment Construction

[0047] The figures show an aerodynamic profile body 1 , which in the embodiment shown is designed as a winglet.

[0048] as by Figures 1 to 5 It can be seen schematically that the profile body 1 has a front profile element 2 which, in a certain operating state of the profile body 1 , is arranged immovably on the aircraft. Furthermore, the profile body 1 has a rear profile element 3 which is arranged movably relative to the front profile element 2 in a certain operating state of the profile body 1 . The front profile element 2 has an air-flowing front profile top 2a and a front profile bottom 2b, and the rear profile element 3 has an air-flowing rear profile top 3a and a rear profile bottom 3b. A profile front edge 4 a (front edge) is formed on the front profile element 2 and a profile rear edge 5 a (rear edge) is formed on the rear profile element 3 . In the illustrated embodiment, the front profile element 2 and the rear profile element 3 are arranged such that the rear pr...

Abstract

The invention relates to an aerodynamic profiled body (1) for an aircraft, in particular a winglet, comprising a front profiled element (2) having a profile front edge (4a), a rear profiled element (3) having a profile rear edge (3a), and an adjusting unit (7), which connects the front profiled element (2) to the rear profiled element (3) and by means of which the rear profiled element (3) can bemoved in relation to the front profiled element (2), wherein the adjusting unit (7) has a front mounting device (8) connected to the front profiled element (2), a rear mounting device (9) connected tothe rear profiled element (3), and a force-transmitting device (10), which connects the front mounting device (8) and the rear mounting device (9) to each other.

Description

technical field [0001] The invention relates to an aerodynamic profile body for an aircraft, in particular a winglet, comprising a front profile element with a profile front edge and a rear profile element with a profile rear edge, and to an aerodynamic profile body comprising such an air Dynamic profile body of the aircraft. Background technique [0002] In aircraft, a wide variety of aerodynamic profile bodies are used, common to which are the outer surfaces around which the air flows. Designed as aerodynamic profile bodies are, for example, so-called winglets, which are more commonly referred to as wing discs and which are mounted as additional parts on the free ends of aircraft wings. The air resistance of the wing is reduced by winglets. The winglets can be obtained in very different embodiments. [0003] The geometry of the profiled body has a significant influence on the fuel consumption of the aircraft, as does its weight. Furthermore, the noise generation of the...
