초록

An actuating mechanism for variable camber leading edges of aerodynamic airfoils characterized by its rigidity and structural stability and which permits varying the camber of a flexible continuous airfoil skin through leading edge deflection angles ranging from on the order of 14°to on the order of 22°with reference to the wing box chord line without deployment of a Krueger flap and up to on the order of 32°with deployment of a Krueger flap; and, which permits varying the camber of a flexible continuous airfoil skin while maintaining a uniform, essentia...
