| Abstract: | In this paper, based on analysis of parafoil opening properties, two-dimensionalopening model of parafoil is presented, canopy radial equation of motion is established.At the same time, parafoil system is assumed to be a two-particle-elastic rod model,then the equation of motion for parafoil system, canopy, and payload is derived. Finally,parameters such as filling time, shock force, inflow velocity, etc. are obtained using com-puter simulation. The simulation program can be used in some parafoil design. |
