Özet

In this paper, the aerodynamic properties of a selected aircraft geometry are calculated in supersonic flow condition using PANAIR. PANAIR is an open-source high-order panel method solver for irrotational and inviscid flows and it is more efficient than higher fidelity CFD analyses for the preliminary design process since it is faster and easier to use. A batch of supersonic analyses is completed for different wing/body configurations for the selected aircraft geometry and with various panel grids, and the results are compared with the experimental data. Different wing planforms and nose configurations are also considered separately to observe the effect of geometry to the prediction accuracy of PANAIR. Moreover, a Class-Shape Transformation (CST) code is also developed to create wing and nose geometries together with the surface panel mesh with parametrization. In addition, SU2 and DATCOM software are used to compare the computational results.
