| Abstract: | Inertia relief theory and static aeroelastic method based on CFD/CSD are introduced in this paper.Three force equilibrium methods of static aeroelasticity are compared with.By comparing with the computational procedures and results of the three methods,it was found that applying inertia relief method in static aeroelastic method can simplify the model constraints,make the model more vivid,and enhance the simulation precision remarkably. |
