Parallel computation of parachute fluid-structure interactions

Abstract

The Army currently lacks the ability to predict accurately the behavior of parachute fluid-structure interaction phenomena. The interactions between the parachute system and the surrounding flow field are dominant in most parachute operations and thus the ability to predict parachute fluid-structure interaction phenomena is of interest to the Army. This paper presents the current status of an ongoing research effort to couple the finite element formulations for the fluid dynamics and structural dynamics encountered in parachute problems. An application of the opening of an axisymmetric round parachute is presented. Future considerations for the coupled model and potential applications of interest to the Army are presented.
