Özet

In this paper we present the preliminary aerodynamic evaluation of enlarged wing-strake and increased wing-sweep modification of an underdevelopment multi-role supersonic fighter aircraft. In this study, higher order panel method is employed in order to explore the high subsonic and supersonic regimes. For this purpose the shareware version of PANAIR code is used. The effect of the wing-strake modification on aerodynamic characteristics of the aircraft is evaluated by comparative study of the original (unmodified) and the modified configurations. The results, for both subsonic and supersonic regimes, indicate reduced static longitudinal stability, increased static lateral stability and increased lift for the modified configuration. Reduction in wave drag is indicated in supersonic regime while an increase in induced drag is predicted in the subsonic regime for the modified configuration. These computed results are quantified in terms of difference in various non-dimensional aerodynamic forces and moments between the modified and original configurations.
