In computation of fluid-structure interactions, we use mesh update methods consisting of mesh-moving and remeshing-as-needed. When the geometries are complex and the structural displacements are large, it becomes even more important that the mesh moving techniques are designed with the objective to reduce the frequency of remeshing. To that end, we present(More)
in the " light " category of weight (2201-10000lbs rigged weights). The integrated system objectives include the ability to airdrop JPADS systems of up to 10,000 lbs rigged weight, from altitudes of up to 25,000 ft mean sea level (MSL), with up to 30kms of offset (in a zero wind condition), and land precisely within 100 meters circular error probable (CEP)(More)
A parallel computational technique is presented for carrying out three-dimensional simulations of parachute uid-structure interactions, and this technique is applied to simulations of airdrop performance and control phenomena in terminal descent. The technique uses a stabilized space-time formulation of the time-dependent, three-dimensional Navier–Stokes(More)
39 T he development of computational models that predict the aerodynamic performance of parachute systems has significantly enhanced the technology of airdrop systems by providing alternatives to or complementing drop tests and laboratory experiments. Increases in the scope and reliability of computational modeling are bringing current technology closer to(More)
