DYNAMICS OF THE ATLAS 5-CPS LONGITUDINAL OSCILLATION FOLLOWING LAUNCH AS RELATED TO THE TANK PRESSURE REGULATION SYSTEM. VOLUME II, PNEUMATIC SYSTEM MODEL DEVELOPMENT,

Abstract

Throughout the Atlas program there is evidence of a longitudinal oscillation of approximately five cycles per second immediately following launch. In many cases this oscillation is distinctly divergent for a short period of time. A few of these cases have reached an amplitude of some concern with respect to a possible failure of the intermediate bulkhead. A dynamic analysis of the 5-cps problem was instigated prior to the last Atlas/Mercury flight (130D), and has since been extended to space launch vehicles. The objectives of this 3-volume study were to explain the oscillation and investigate methods to eliminate or minimize the problem. This report discusses the five cycles per second oscillation in terms of coupling between the vehicle/fluid structure and the pneumatic tank pressure regulation system. (Author)
