초록

A fluid dynamically effective surface of a device moving in a fluid, especially a lifting surface of a flying machine, has an elastic axis extending in the span direction of the surface, and an adjustable control surface. The lifting surface is elastically deformable in a bending direction and/or in a torsion direction about the elastic axis, due to and dependent on the adjustment of the control surface, while changing the induced fluid dynamic drag. A control and/or regulating arrangement is provided for adjusting the control surface in the sense of min...

The invention claimed is: 1. An aircraft wing arrangement comprising: an aircraft lifting wing bounded by a leading edge, a trailing edge and a wingtip edge, wherein said wingtip edge is an outward end edge of said lifting wing, which outward end edge extends from said leading edge to said trailing edge, and wherein said lifting wing is elastically deformable in a bending direction and in a torsional direction about an elastic axis of said lifting wing extending in a span direction outwardly to said wingtip edge between said leading edge and said traili...
