Aerodynamics of ParachutesThe T*AFSM is developing advanced methods to simulate different deployment stages of various parachutes systems. The methods take into account the fluid-structure coupling between the aerodynamics of the parachute, which depends on the instantaneous shape of the parachute, and the deformation of the parachute, which in turn depends on the aerodynamical forces acting on the parachute. The core method used in these computations is the DSD/SST formulation [1-10, 16-17, 19], which was developed by the T*AFSM for flow problems with moving boundaries and interfaces, including fluid-structure interactions. With the techniques developed, simulation and modeling of a wide range of parachute applications have been carried out [11-15, 18, 20]. References:1. T.E.
