Airfoil device and method providing smooth, continuous, variation in airfoil camber and surface curvature over substantially the entire length of the device by use of a trusslike bendable beam as an airfoil rib having the airfoil skin surfaces flexibly slidable relative thereto. The beam is divided chordwise into upper and lower beam members each formed of a plurality of articulated sections. The beam members are connected by a bendable jackscrew which upon rotation causes one member to move chordwise, and its curvature to be changed, relative to the oth...
An airfoil variable cambering device for varying the camber and the outer surface curvature of an airfoil in a smooth, continuous fashion over substantially the entirety thereof which comprises: airfoil rib means positioned in the airfoil for giving structural support thereto, outer directed portions of the rib means approximately defining a major portion of the airfoil cross section; airfoil outer skin means arranged over said outer directed portions of said rib means to form substantially smoothly continuous outer surfaces for the airfoil; means connec...
