High Speed Aerodynamics 04: Airfoils in Supersonic Flow

The approaches to analyzing the aerodynamics of airfoil shapes in supersonic flow are discussed. Where the angle of attack, thickness and camber are small, it is possible to get good results using thin airfoil theory, where the slope of the surface is directly related to the pressure coefficient. Where slopes get larger due to increase angle of attack, camber or thickness, the shock-expansion method is used. Please click to download pdf notes
