Wing Drag Prediction and Decomposition

A wake integration methodology to predict the aerodynamic characteristics of threedimensional wings in viscous subsonic and transonic flows is presented. Results indicate that wake integration is viable as a method of drag prediction and, compared to surface integration, has the added benefit of being able to provide a decomposition of the total drag into its physical components of profile, induced, and wave drag for a wing in viscous, transonic flow. Future work will involve using wake integration on postprocess flows about more complex configurations for which this study provides a sound basic framework.
