Abstract : The aerodynamic properties of the boundary layers and wakes of slender hypersonic vehicles are characterized by means of ballistics range data and their attendant analysis. The investigations have the following general objectives: (1) measurement of aerodynamic properties that characterize the boundary layers and wakes of slender vehicles, (2) evaluation of the experimental data to compare with existing theories, and (3) modification of current theory as required in the interpretation of the experiments. The major tasks considered include: (1) program management, (2) measurement of turbulent skin friction on a slender cone, (3) effect of high heat transfer rates on boundary layer transition, (4) body-scale effects on the aerodynamic characteristics of wakes, and (5) the effect of heat transfer on the aerodynamic characteristics of wakes. Technical progress, problem areas and methods of solution are each discussed. The proposed schedules for major tasks and subtasks are presented. The current plan of approach and the degree of completion of subtasks are outlined. (Author)
