My intuition of the way the aerodynamic perturbations work is that
their relative magnitude is not particularly dependent on how optimized the
plug shape. In addition, having a simple engine shape, like a straight
cone, makes it easier for ourselves and others to make CFD models of the
engine. You don't need to worry about generating a mesh for a cone.
