Constraint-based Shape Parameterization for Aerodynamic Design

We present a method for constructing design-appropriate shape parameterizations of discrete surfaces for optimization of flight vehicles. The method allows the designer to choose a set of points located on the aerodynamic surface to serve as design variables. Arbitrary geometric constraints can be prescribed and are intrinsically incorporated into the parameterization. The technique supports bo...

Aerodynamic Shape Optimization Using Unstructured Grid Methods

Two unstructured-grid Euler-based CFD codes, AIRPLANE and FLOWCART were coupled to a gradientbased quasi-Newton finite-difference optimization algorithm. These two optimization techniques were developed to provide detailed aerodynamic shape optimization methods for complete configurations with efficient grid generation methods. AIRPLANE utilizes a tetrahedral mesh whereas FLOWCART uses a hexahe...

Molecular dynamics-based unstructured grid generation method for aerodynamic applications

A new approach to triangular mesh generation based on the molecular dynamics method is proposed. Mesh nodes are considered as interacting particles. After the node placement by molecular dynamics simulation, well-shaped triangles or tetrahedra can be created after connecting the nodes by Delaunay triangulation or tetrahedrization. Some examples are considered in order to illustrate themethod’s ...
