From: mikkelhaaheim@gmail.com Are you taking into account the effect of atmospheric pressure on the thrust from a pressure fed engine? Isp at sea level is considerably lower than vacuum, meaning thrust will be much lower as well. Also, the propellant tanks might be unable to supply sufficient propellant volume given the resistnce from air pressure. --- SoupGate-Win32 v1.05 * Origin: you cannot sedate... all the things you hate (1:229/2) |
