TRANSONIC STATIC AND DYNAMIC STABILITY CHARACTERISTICS OF SEVERAL SATURN IB AND V UPPER STAGE CONFIGURATIONS

Abstract

Dynamic stability characteristics of six Apollo-Saturn 1B and 5 and one Saturn-Centaur upper stage model configurations and static stability characteristics of two Apollo-Saturn B and 5 upper stage model configurations were obtained from M = 0.50 to 1.40. The primary test objective was to investigate the changes in dynamic stability characteristics as a function of pitch oscillation center. A secondary objective was to compare three different model mounting techniques - sting, transverse rod, and reflection plane. The static testing resulted from a suspected nonlinear phenomenon observed during the dynamic phase of the test. One model configuration which was stable when the pitch oscillation center was ahead of a separation disk exhibited limit cycle oscillations when the pitch oscillation center was located aft of the disk.
