Numerical prediction of deployment, initial fill, and inflation of parachute canopies

Conference ·
OSTI ID:5250415
An analysis is presented for predicting parachute deployment and inflation in incompressible flow. Equations of motion are developed from first principles as applied to a discrete element representation of the canopy, suspension lines, payload, and deployment bag/pilot chute. Fluid conservation equations for deforming, accelerating control volumes are solved to determine the flow properties of the captured fluid. The unsteady pressure distribution in the internal flow is used to drive the equations of motion for the discrete element representation of the system, which in turn provides the unsteady boundary conditions for the fluid conservation equations.
