摘要
Abstract
A numerical simulation based on CFD/CSD method has been carried out to study the transonic static aeroelastic problems of large transporters.The specific methods are described as follows:the Reynolds-averaged Navier-Stokes equations (RANS) and the static aeroelastic balance equation are employed as the governing equations to conduct coupling iterative computation;a multi-block structured grid is generated for parallel CFD computation,and a multi-grid technique is adopted to accelerate convergence;the dynamic mesh generation is completed through the RBF combined with the TFI method;a three-dimensional thin plate spline interpolation technique is adopted to execute the data interchange between the flow field and structure.Based on the above methods and typical wind tunnel test data,a series of codes are developed and validated,and the results indicate the effectiveness of the methods.Finally,the deformation characters,the pressure distribution,and the aerodynamic performance of a typical large transporter's wing are analysed on the basis of the numerical results.关键词
