Lines: 15 Keywords: Engine design Xref: mnetor sci.math:2534 sci.misc:659 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. Mike of the MAD Scientists Rocket Club.
