Computer Simulation of Parafoil Dynamics

Abstract

Three-dimensional transient simulations of unconstrained flight of a parafoil system are performed using a structural finite element model with prescribed pressure and drag forces. In general, simulation of parafoil flight requires coupling of a structural model with a fluid dynamics model. The approach presented here is an intermediate step towards a fully-coupled simulation. Since the structural model is considerably smaller than the required fluid dynamics model, these intermediate simulations are considerably easier to perform and provide a relatively simple method to evaluate parafoil flight. Simulations of the inflation from the initial cut pattern, steady glide, and turning and flared landing maneuvers are presented.
