Intergrid Transformation for Aircraft Aeroelastic Simulations

摘要

This Note has considered the generalization of a transformation method for passing information between structural and aerodynamic surface grids for aeroelastic simulation. The initial method was developed for isolated aircraft components. This has been extended to consider multiple connected components by allowing different parts of the structural model to drive the fluid surfaces in a hierarchical manner, and then blending the resulting fluid positions to ensure that the different parts of the fluid surface mesh remain attached. The method has been applied for wings, tailplanes, and a vertical fin attached to a fuselage. Future work will consider components attached to the wing (e.g., fuel tanks or stores). The next stage of this work is to apply the transformation to the time-domain aeroelastic simulation of complete aircraft.
