Fluid-Structure Interaction Calculation Framework for Non-Rigid Airship Based on Explicit Dynamics

The non-rigid airship is a low-rigidity and inflatable aircraft which has obvious fluid-structure interaction characteristics. In this paper, the unsteady explicit dynamic fluid-structure interaction analysis framework of non-rigid airship is constructed based on the parametric section (PARSEC) meth...

In this paper, the unsteady explicit dynamic fluid-structure interaction analysis framework of non-rigid airship is constructed based on the parametric section (PARSEC) method, the radial basis function (RBF), and the Delaunay mapping method. The reliability and accuracy of the numerical method are verified by the cases of plate impact and the aeroelasticity of NACA0014 wing.
