Effect of Two Dimensional Suction Flows into Double Intakes on the Upper Surface of a Joukowski Airfoil,
Abstract
Fan-in-wing type vertical take-off and landing aircraft are under investigation in the development cycle of new classes of aircraft for military and civilian missions. In view of inadequate theoretical and experimental information available, some preliminary analyses of two-dimensional problems are explored. The effect of suction flow alone on the aerodynamic characteristics of an airfoil exhibit certain novel features such as invalidation of Kutta condition for high values of intake to free stream velocity ratio. With a view to understand the flow characteristics when two intakes are located on the upper surface of a Joukowski airfoil, the two-dimensional potential flow theory is applied. (Author)
