This study presents the aerodynamic analysis of a sweptback wing using Computational Fluid Dynamics (CFD). The sweptback configuration is widely used in modern aircraft to delay shock formation at transonic speeds and to reduce wave drag. In this work, a 3D wing model with a specified sweep angle is analyzed under subsonic and transonic conditions. CFD simulations are performed to obtain lift, drag, and pressure distributions, and the results are compared with a reference unswept wing configuration. The findings demonstrate the aerodynamic benefits and trade-offs of sweepback in terms of lift-to-drag ratio and flow separation characteristics.
