초록

An airfoil having a support frame, a rigid nose section, and upper and lower variable camber skin sections extending from the nose section rearwardly to the support frame. The frame has a rigid mounting arm which extends forwardly into the variable camber section, and a pivot link is connected from that mounting arm to a lower portion of the nose section so that is is able to swing downwardly and rearwardly to its cambered position. A toggle linkage connects an upper portion of the nose section to the frame just beneath the upper variable camber skin sec...
