What equation exactly in the first reference has the derivation?

D H said:No. I placed this paper in camp 3, Newton's laws don't apply to variable mass systems, which in my mind is a stick one's head in the sand position. Aerospace engineering is plain old Newtonian mechanics. We've been flying for over a century now, and flying modern rockets for nearly that long. Descriptions of flying machinery is almost always done in a Newtonian (read: not Lagrangian) sense. So to say that Newtonian mechanics doesn't apply to such devices is just silly.
