I am part of a reasonably sane assemblage of Amateur rocket enthusiasts
here in Arizona. What I'm looking for is a Mathematical
wizard who can reduce gas law equations into step-by-step calculations. I have
limited math background and need not only to be able to calculate volume
and density flows but also use the product to design nozzles. We're growing
weary of paying exhorbitant prices for minimally powered engines from various
suppliers. The K250 (producing 10 secs of 2300 Newton secs of thrust) is
a good engine, but the price is prohibitive for now. Using some knowledge
we have from various books, we are short a few pieces; (1) Gas Law math
made easy (I see you're laughing) (2) Better equations for nozzle design.
(3) Composite solid propellant formulas (we have 3, they are inefficient
and experimentation isn't our bag).
Thanks for your help.
