High Performance and High-Fidelity Aeroelastic Simulation of Fixed Wing Aircraft with Deployable Control Surfaces
Abstract
The goals of this research is to overcome the difficulties created by mesh shearing in the simulation of aircraft with large control surface deflection. The origin of the difficulties for the correct modeling of large control surface deflection is that they introduce shearing in the mesh at the place where the control surface meets the fixed part of the wing. Such a geometrical shearing is very difficult to handle, in particular in Finite Volume or Finite Element approaches. One option to tackle this problem is the use of Chimera grids. However Chimera grid approaches are relatively expensive in geometric computation and introduce an interpolation error due to the overlap of the grids. We have proposed to explore two alternate methods to tackle this issue: Meshfree methods and Level-Set Methods. At the end of the project, we had demonstrated that the node activation/ deactivation method worked on a sample one dimensional problem and the implementation in two dimensions is still in progress.
