Hi all,
I'm wondering about the theory behind maximising rocket thrust. The equation F = m(dot)V + (Pe - Pa)Ae seems to suggest that this is maximised when Pa=0. However, other sources (e.g. braeunig.us) say that you want Pe=Pa. Indeed, as far as I can see, Sutton contradicts himself and says both! Please, could someone help me out?!
Many thanks!
