Mechanical and numerical modelling of fluid-structure vibration instabilities of liquid propelled launch vehicles
Abstract
We present various variational formulations adapted to the problem of dynamic stability analysis of liquid propelled launch vehicles. Sloshing vibrations including surface tension effects, hydroelastic vibrational and structural acoustic vibrations are analyzed, using appropriate symmetric finite element procedures, in order to obtain accurate modal characteristics of the launcher for stability analysis.
