Influence of a High Velocity Fluid Environment on the Static and Dynamic Stability of Thin Cylindrical Shell Structures.

摘要

A combined theoretical and experimental research program has been carried out to investigate the stability characteristics of thin-walled circular cylindrical shell structures exposed to a high velocity fluid dynamic (aerodynamic) environment. As a result of this study, several basic observations were made concerning the degree of sophistication required in the analytical modeling of this problem. The present study shows that a supersonic fluid dynamic environment can significantly complicate the dynamic stability characteristics of thin cylindrical shell structures while introducing no significant complications to its static stability features.
