摘要

For the design of highly stressed aerodynamic control surfaces, i.e. fins, of subsonic and hypersonic flight vehicles the use of numerical methods like FEM and CFD, solving the Navier-Stokes equations, will be necessary. With respect to aeroelastic effects, the coupling of both methods to fluid-structure interaction (FSI) capabilities will lead to tremendous new possibilities in engineering applications for industrial use. Regarding the complex mathematical and numerical background of FSI, the new methods have to be tested and verified stepwise on real projects to evaluate the reliability of the new possibilities. On some fin structures models for a subsonic flight vehicle and a hypersonic flight vehicle the fluid-structure interaction capabilities of ADINA will be presented and discussed.
