Vortex Effects for Canard-wing Configurations at High Angles of Attack in Subsonic Flow [PDF]
A fully three-dimensional subsonic panel method that can handle arbitrary shed vortex wakes is used to compute the nonlinear forces and moments on simple canard-wing configurations. The lifting surfaces and wakes are represented by doublet panels.
