Abstract:

Surface pressure tests were made on a scale model of the Viking Lander Capsule at Mach number 10 and Reynolds numbers, based on the model aeroshell radius. Angle of attack was varied from -26 to 26 deg. with yaw angles of -5 and -10 included at the capsule estimated trim angle of attack of 11.2 deg. Results show the effect of protuberances representing a camera bump, an antenna, a reaction control system, and other appendages on the base cover pressure distribution. Comparisons with data from another test facility are also presented. Author
