A test was conducted at Mach number 7.2 on a blunt cone featuring porous skins for mass addition to the boundary layer. Transition location was determined in relation to variations of Reynolds number, mass flow, and angle of attack. As expected, transition locations were dependent upon angle of attack for the range of angles tested 0 to 5 deg. However, only the highest mass flow rate of 0.042 lbmsec injected through the nose section produced significant effects on the location of transition.
