Parachute Deployment Simulations using LS-DYNA ICFD Solver and Strong FSI Coupling

The main goal of military airdrops is the accurate delivery of cargo released from a moving air vehicle via parachute. The airdrop trajectory results from the movement of the dropped package and the dynamics of the parachutes deployment (Fig.1:). After having treated the freefall of a rigid object in the near flow of an airplane ([8]), the present paper focuses on the parachute deployment modelling and its challenges in LS-DYNA.
