Reflection of a Weak Shock Wave From a Boundary Layer Along a Flat Plate 1: Interaction of Weak Shock Waves With Laminar and Turbulent Boundary Layers Analyzed by Momentum-Integral Method

Note presenting an investigation of the phenomena encountered when a plane oblique shock wave is incident upon the boundary layer of a flat plate. The flow field was divided into a viscous layer near the wall and a supersonic potential outer flow. With the outer flow determined, boundary-layer growth and pressure distribution were computed and results for the laminar cases were obtained and provided.

On the flying qualities of helicopters

Report presenting the flying qualities problems of current helicopters, including instability with angle of attack in forward flight, control sensitivity in hovering, and control forces following control movement in maneuvers. Some possible solutions to these issues are presented.
