摘　　要：为研究下反前掠地效翼的气动性能,利用FLUENT求解定常不可压N-S方程和可实现的k-ε湍流模型,建立在地面效应下地效翼流场的三维数值模型,对不同下反角和前掠角的地效翼进行数值模拟.计算结果揭示出下反角和前掠角对地效翼空气动力特性、流场特性和纵向稳定性的影响规律.对下反前掠地效翼的三维数值模拟可以为地效飞行器的设计和优化提供参考.To study the aerodynamic performance of reverse forward swept wing-in-ground effect,the 3D numerical model of flow field of wing-in-ground effect is built under ground effect by solving steady incompressible N-S equations and realizable k-ε turbulence model based on FLUENT,and the numerical simulation on wing-in-ground effect is performed under different reverse angles and forward swept angles.The computation results indicate the influence law of reverse angle and forward swept angle on aerodynamic characteristics,flow field characteristics,longitudinal stability of wing-in-ground effect.The 3D numerical simulation on reverse forward swept wing-in-ground effect can provide references for the design and optimization of wing-in-ground effect craft.
