I took another look at his equation. His force is not the lift force but is shown opposite to the drag force. So, C is related to the drag coefficient Cd? Well, not quite. Drag is pretty much constant over a small range of the angle he calls alpha. The problem is that 1 - cos(alpha) goes as (alpha)^2 for small values of alpha. In other words his force goes to zero dead on, which is is not supported by physical evidence. It's time to put this "theory" in the garbage bin where it belongs.
