In this study, low-speed aerodynamic characteristics of a rectangular wing with airfoil section NACA 0012 and a kinked wing with airfoil section NACA 747A315 are investigated numerically using a panel code CMARC. The code CMARC, which is an enhanced version of NASA's PMARC-12, is an inviscid fluid flow analysis code of type known as a low-order panel method. Through the comparison with the results by high-order panel code PAN AIR and VLM (Vortex Linear Method) code, validity and suitability of CMARC code were assessed. It turned out that CMARC results are generally in good agreement with those by other methods in the case of the problems studied. The use of CMARC code can be extended to more complicated problems such as stability analysis of a small aircraft in the subsonic regime.
