Gordon-McBride program

The program, called Stanjan [8] (see Appendix I), is readily handled even on the most modest computers. Like the Gordon-McBride program, both approaches use the JANAF thermochemical database [1], The suite of CHEMKIN programs (see Appendix H) also provides an equilibrium code based on Stanjan [8],...

First, the literature should be searched for spectroscopic data, and if these are sufficient, the thermodynamic properties can be calculated by statistical mechanics formulas. McBride and Gordon s program (1967) is recommended for this purpose. The latest verson, PAC3, includes, among many possible calculation methods, an accurate calculation method for internal rotation contributions, which are important when organic species are involved, and a subroutine which automatically calculates the coefficients of the NASA polynomials. Wilhoit s extrapolation method was recently included in the code.

There are various mathematical approaches for solving these equations by numerical methods [4, 6, 7], The most commonly used program is that of Gordon and McBride [4] described in Appendix I. 

As stated, the most commonly used procedure for temperature and composition calculations is the versatile computer program of Gordon and McBride [4], who use the minimization of the Gibbs free energy technique and a descent Newton-Raphson method to solve the equations iteratively. A similar method for solving the equations when equilibrium constants are used is shown in Ref. [7],...

The prediction of rocket propellant specific impulse, as well as impulse under other conditions, may be reliably accomplished by calculation using as input the chemical composition, the heat of formation, and the density of the component propellant chemicals. Not only impulse but also the composition of exhaust species (and of species in the combustion chamber and the throat) may be calculated if the thermodynamic properties of the chemical species involved are known or can be estimated. The present standard computer code for such calculations is that described by Gordon and McBride.44 Theoretical performance predictions using such programs are widely used to guide propellant formulation efforts and to predict rocket propellant performance however, verification of actual performance is necessary.
