Aside from computerized simulators, is there an easy to predict altitude based on impulse and weight? I'm not talking perfect--just ballpark.
A guy at URRF who had just bought a Leviathan and an H133 motor for his Level 1 cert asked me, "With this motor, how high will it go?"
Of course, out on the field with no computer, I told him to look at the package, see what it tells you for a G80, then extrapolate for an H133 (given the known total impulse for both).
Anyone know of an easier way? Be nice if there was a web site with a table that lists common total impulses by rocket weight and a resulting rough avg. altitude.
