Hypersonic flow separation and its effects on control characteristics were investigated analytically and experimentally. Included are conclusions drawn from extensive test data for hypersonic flows over 'basic' geometries and over 'typical' flight configurations with aerodynamic controls. The basic flow geometries discussed include: separation on flat plates ahead of ramps (flaps); flows over sharp expansion corners; 'breakaway' separation; and fin plate interactions. Force data and limited pressure and heating rate distributions are presented for the flight configurations for various trailing edge flap settings. As a supplement to this work, available sources of pertinent hypersonic controls data are tabulated.
