Note (General): Hypersonic wind tunnel tests were conducted to measure the pitch damping characteristics of a series of capsule-type vehicles at a Mach number of 7. 1. Data were obtained utilizing thesmall amplitude free oscillation technique at angles of attack from 0 to 10deg at a Reynolds number of 4.5×104, based on a unit length (cm). Model configurations are classified into two types, i. e. , 1) a blunt cone type (S-type) which consists of a model with half cone angles of 6゜ and 10゜, and 2) acapsule type (M-type) which has a blunted forebody followed by a conical boattail and cylinder. Results of the tests indicate that S-type models are dynamically stable through the angles of attack, whereas M-type models reveal dynamic instability at low angles of attack. These trends are thought to be due to flow reattachment effects occurring on the cylinder surface of the capsules. These undamping results can be eliminated or greatly reduced by taking angles of attack.
