Abstract:
Lift body having a variable camber, comprising:a lift body structure including a suction-side skin and pressure-side skin forming a fluidically favorable profile which at least at times generates a lift or a transverse driving force, said lift body structure being substantially hollow, said lift body structure being elastically deformable at least downstream of a largest profile thickness thereof,several web-type connections between the suction-side skin and the pressure-side skin,an integrated adjusting device comprising at least one dimensionally stable adjusting body which is rotatable about a defined axis and is coupled with areas of the skin to be deformed,wherein in a deformation range of the lift body structure, each adjusting body has a curved conical shape with a cross-section corresponding to a thickness of the lift body structure; andwherein, during all operating positions of the lift body, at least a portion of each adjusting body is in direct linear contact with the skin of the lift body whereby each adjusting body continuously supports the skin of the lift body during all operating positions of the lift body.
