Damping-in-Pitch and Drag Characteristics of the Viking Configuration at Mach Numbers from 1.6 through 3

Abstract

Wind tunnel tests were conducted to substantiate earlier test results from another AEDC facility and to determine the dynamic stability characteristics of the Viking-Balloon Launched Decelerator Test (BLDT) configuration. The dynamic instabilities at zero angle of attack which were found during the previous tests were verified by the present tests. For angles of attack of 3 to 15 deg at all Mach numbers, the BLDT configuration was dynamically stable, and the damping derivatives were generally independent of the test variables. Free-flight drag coefficients show good agreement with coefficients obtained from tests on a similar configuration with a string- supported model.
