Nick,

Sometime later on, I'll show you the Gordon-McBride code. It's been around for decades and widely distributed. Pickup almost any random textbook on thermodynamics written in the last thirty years and you'll probably find Gordon and/or McBride referenced. Their code is sometimes called the "Lewis Code" because they both worked at NASA Lewis (now called NASA Glenn). Also their algorithm is sometimes called the "NASA method". There are probably copies of their program floating Australia (most good NASA programs including the export restricted ones end up in Australia eventually). If you latch onto a copy of the Gordon-McBride code make sure you have the last version of it (12 Dec 1996). Both(?) McBride and Gordon(?) are now retired (they're OLD NASA) and their code is frozen. Prior to their retirement they hooked into a pot of NASA money through the National Aerospace Plane (NASP) X-30 project. NASP was supposed to be a scramjet demonstrator and their code was improved to better understand combustion processes. NASP later died a horrible death but fortunately they were able make significant improvements to their code and thermodynamic/transport property database before the money went away (they then wisely retired). For example the earlier version of their code crashed if one tried to simulate Titan's atmosphere but the latest-and-greatest version handles Titan nicely. What I need to do is lift out the bits of their code that made Titan work and include it in mine.
