A long succession of Delta vehicles (including their Thor/Delta and Thor/Agena predecessors) have experienced pogo instability in the twenty seconds prior to cutoff of the first stage. The study reported here led to the suppression of this instability on the ITOS-F vehicle launched in November 1973. Suppression was achieved by the addition of flow resistance to an existing accumulator installed in the lox suction line. The ability to achieve the suppression resulted from a joint study by The Aerospace Corporation and McDonnell Douglas Astronautics Corporation. The study was designed to develop a pogo stability model yielding eigenvalues and eigenvectors consistent with flight data over a range of vehicle configurations, engine operating conditions, and presence or absence of a lox accumulator. Extensive reduction of flight data in the form of spectral analyses was required. Based on this model, it was possible to optimize the accumulator resistance for vehicle stability. (Author)
