Study on static aeroelasticity for high aspect ratio joined-wings

Based on Euler/N-S equations and multi-block structure meshes technology, coupling the structure equilibrium equations, an efficient simulation procedure is established for static aeroelasticity of the aircraft. A threedimensional dynamic grid technology is presented based on Delauney map, then the higher mesh quality and faster computational effect for mesh update could be obtained. High aspect ratio joinedwings is studied by means of static aeroelasticity method, then the effect of attack angle and fuselage are also discussed. According to videogrammetry deformation measurement, this method is comparative accurate, thus suitable for engineering application.
