Abstract:

Analysis of problems involved in direct wind-tunnel simulation of natural interactions between a hypersonic viscous flow and a laminar boundary layer on a plate positioned at zero angle of attack is examined. Direct simulation implies the possibility of relating the experimental data directly to the natural conditions. Calculated data are given for the effects of individual similarity parameters on the lift and drag coefficients, and practical recommendations are included for relating the results of wind-tunnel experiments to natural situations.
