Abstract

This paper focuses on the pogo phenomenon which is the longitudinal instability of space launch vehicles. For the prediction of the pogo phenomenon, it is essential to establish appropriate structural modeling and conduct the modal analysis of the launch vehicles. It was conducted using the axisymmetric two-dimensional shell elements in the present paper. The present in-house analysis is developed by referring to the relevant documents using MATLAB. The program was validated using examples of the existing launch vehicles. The comparison in terms of modeling and results against the existing documents is shown. Other applications and plan for the pogo analysis are also suggested.
