So, for any given rocket, S and Cx are constants.<br /><br />What would be nice would be a chart showing acceleration versus Force of Max Q.<br /><br />And another chart showing acceleration versus altitude of Max Q.<br /><br />I know that these charts would only be crude approximations.<br /><br />What I'm getting at is this. If the rocket launches from sea-level, then the higher the acceleration the lower the total loses from gravity would be, but the higher the loses from drag would be.<br /><br />At what acceleration do you get the minimum losses?<br /><br />Now, of course I know that acceleration is not a constant. In fact it increases as the rocket burns off fuel.<br /><br />Actually, now that I'm lookig at it. I don't know what I'm asking.... LOL
