Abstract:

Generalized protuberances in the form of right circular cylinders of 2-, 4-, and 8-in. diameter were mounted on a full-scale Saturn S-4B panel and tested at various heights for Mach numbers 0.60 through 1.60. Models of the Auxiliary Propulsion Unit and the Rocket Control System protuberances of the Saturn V launch vehicle were also tested. The Reynolds number based on the generalized protuberance diameters varied from 0.25 to 3.0 million. Static and fluctuating pressure levels in the regions around the protuberances were determined, and flow visualization studies were also made. The fluctuating pressure and flow visualization data are not presented in this report.
