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.
