Model Forum / General / Rockets / April 2006

is there a calculator or spreadsheet on the net to calculate the thrust
parameters for a hybrid rocket? I was thinking along the lines of
something where you plug in type of fuel, volume of Nox used,
combustion chamber size and rate of nox flow.

then after you put this in, it gives you total impulse, average thrust,
and other such goodly numbers.

I also would like to know(in hybrids) how one determines chamber
pressure, and if one could modify that also.

been lookin at possibly doing a big ex hybrid, and would like to see
what size engine woudl be needed. har to tell where to start for weight
unless you can get the weight of the casing.
