A Software Development For Wing-in-Ground Airfoil Optimization

Compared with general aircrafts and ships, the wing-in-ground air vehicle features high aerodynamic efficiency, safety, high speed, comprehensive use and potential development toward huge vehicle of thousands tons.The target of this thesis is to develop a design and optimization tool for airfoils of wind-in-ground air vehicle. The functions of the tool include: to generate wing-in-ground air vehicle airfoil by relative less control points, to simulate the wing-in-ground effect by the mirror method, to analyze aerodynamic performance of the airfoil using the software Javafoil and to optimization the airfoil by the based-surrogate optimization method.The design tools of iSIGHT such as integration, design of experiment, approximation and optimization are applied to develop the design and optimization software for airfoils of wing-in-ground air vehicle. The examples in this paper demonstrate that the software can use for general purposes and can obtain good designs.
