Abstract : The principal objective of the investigation was to determine analytically the potential aerodynamic performance improvements that may be achieved through the use of variable camber. The feasibility study considered initially systematic camber variations on two-dimensional airfoils representative of successful airfoils in widespread current usage and of a most promising research airfoil. The application of variable camber to each of these airfoils resulted in significant expansions of their performance envelopes. It was found that the 'Whitcomb Supercritical Airfoil' achieved outstanding aerodynamic performance throughout the speed regime studied. (Author)
