In this lecture, we derive Prandt's famous Lifting Line Theory. Essentially, this theory models a finite-wing + wing tip vortices as a horseshoe vortex, where the wing is replaced by a vortex and the strength distribution along the vortex represents the wing's lift distribution. We go over the example for an elliptic distribution of vortex strength and why that distribution is particularly important to Aerodynamics.
