An account is given of wind-tunnel measurements at low supersonic speeds of the pressure distribution on a doubly symmetrical double-wedge profile of approximately 8-percent thickness. The results cover the Mach number range form 1.166 to 1.377, which brackets the value (1.221) given by exact inviscid theory for attachment of the shock wave to the leading edge at zero angle of attack.
