An investigation has been made to determine Reynolds number and Mach number effects upon the base pressure of a nonlifting ogival body of revolution over the Reynolds number range in which wake transition occurs. The tests covered a Reynolds number range of approximately 20,000 to 10,000,000 and a Mach number range of 1.62 to 2.62. The results were compared with previous base-pressure data and also with the qualitative theoretical predictions of Crocco and Lees. Throughout the realm of wake transition the base pressure was found to vary with both Reynolds number and Mach number in the same qualitative manner as given by the theory of Crocco and Lees.
