CFD BASED DYNAMIC MODELLING OF PARAFOIL SYSTEMS IN THE WIND ENVIRONMENT

摘要

Parafoil systems are a kind of flexible wing vehicle flying at low altitude, which are more susceptible to winds. Computational fluid dynamics (CFD) technology is applied to simulate parafoils flying with winds. And then, the equivalent force and action point of the wind are obtained through CFD simulation analysis. Further, a six degree of freedom (DOF) dynamic model of the parafoil system in the wind environment is established. The study shows that the established model can better describe the flight characteristics of the parafoil system in windy conditions.
