基于CFD的风雨环境翼伞动力学建模
Dynamic modeling of parafoil in wind and rain environment based on CFD method
摘要
Abstract
In order to explor the influences of wind and rain on parafoil flight characteristics,parafoil dynamic model was introduced in wind and rain environment by adding the effect factors of rain film,wind load and rain load into its aerodynamic equations.Then,the wind and rain environment was simulated by the CFD method:with wind simulated by mesh velocity,rainfall simulated by multiphase flow and parafoil attitude simulated by dynamic mesh,the Reynolds Averaged Navier Stokes (RANS) equations were solved for the supplements and verification of parafoil aerodynamic equations,so as to complete the task of parafoil dynamic modeling in wind and rain environment.The result shows that CFD simulation results is close to classical NASA wind tunnel test results,which verifies the rationality of parafoil aerodynamic equation.Parafoil dynamic model established in this paper describes the flight characteristics of parafoil in wind and rain environment,which provides a new idea for parafoil modeling in complex environment.关键词
