Zhou Zhou · Flight Dynamics · 2010
In this paper,an effective and well robust dynamic grid deformation method based on the Delaunay graph mapping is developed to solve the deformation of 3-D hybrid multiblock grids.The static aeroelastics problems of large aspect ratio UAVs are investigated by the finite volume method coupled with structure static equations.The comparison,analysis and investigation were done as well.The result is improved that the technology of dynamic grid based on Delaunay graph mapping is a better solution of viscous dynamic grid deformation.This method has better capability of solving the complex aeroelastics problems.
