Abstract : This report is a summary of a large number of research tasks performed in the area of low speed aerodynamics. The research projects are fundamental in nature but of relevance to the Navy. Both the theoretical and experimental aspects of each problem have been studied and the results are compared. Numerical methods have been used in self contained computer programs to calculate the aerodynamic performance of the following configurations: Two dimensional circulation controlled wings with blowing and regions of separated flow; two dimensional thrust augmented VTOL wings with jet entrainment effects; and rotors in hover with arbitrary twist, taper, and airfoil cross section using nonlinear lifting surface theory. Additional experimental work has been done in the area of rotor wake instabilities in and out of ground effect. (Modified author abstract)
