Pressure Test on the Viking Lander Capsule at Mach Number 10

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....

Zusammenfassung:	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) Prepared in cooperation with ARO, Inc., Tullahoma, Tenn. Rept. no. ARO-VKF-TR-72-158.
