Abstract : The weak interaction effect on cone surface pressures was measured and found to be in good agreement with theory. Correlation was established at a nominal Mach number of 14 with the value of the hypersonic interaction parameter, based on free-stream conditions, ranging from 4 to 20. By using an inverse approach, the cumbersome iteration method suggested by Talbot has been simplified to a one-step calculation. The results are nearly identical with Probstein's first-order theory for values of the hypersonic interaction parameter less than twenty. Computer solutions were found for 5, 10, 15, and 20 degree semivertex angle, sharp-nosed cones at free stream Mach numbers between 5 and 20 and wall to adiabatic wall temperature ratios between .1 and 1.
