A variable-camber airfoil includes a four-bar linkage camber altering mechanism and a flexible panel in the lower skin of the airfoil. A flexible upper skin extends from the upper end of a front spar assembly to the upper end of a nose structure of the airfoil. A rotary actuator is mounted forward of the front spar assembly within the cavity of the airfoil, and is used to actuate the camber altering mechanism. A main drive arm, which acts as a link in the camber altering mechanism, extends forwardly from the rotary actuator. To actuate the camber alterin...
1. A variable-chamber airfoil having a span and a chord, comprising: a front spar assembly, said front spar assembly extending spanwise through said airfoil and being affixed to said airfoil; a nose structure, said nose structure including the leading edge of said airfoil; an upper panel, said upper panel extending from adjacent said front spar assembly to adjacent said nose structure, said upper panel being flexible in a chordwise direction and forming a continuous upper aerodynamic surface of said airfoil between said front spar assembly and said ...
