Librpa development library

Librpa is a multi-platform C++ library for solving combustion and rocket performance problems.

Librpa is a calculation core of RPA, distributed with both Lite and Standard editions of the software.

If you want your program to link against the library, please contact the author

Key features

• Robust, proven and industry-accepted Gibbs free energy minimization approach is used to obtain the combustion composition
• Expandable thermodynamic data library based on NASA Glenn thermodynamic database includes data for numerous combustion product species, as well as data for such propellant components as hydrogen, oxygen, RP-1, RG-1, sintin, methane, propane, hydrogen peroxide, MMH, and many other
• Analysis of monopropellant and bipropellant rocket engines
• Analysis of rocket propulsion engines with an arbitrary set of propellant components (multipropellant systems)
• Calculation of performance for a finite- and infinite-area combustion chambers
• Analysis of nozzle flows with shifting and frozen chemical equilibrium
• Calculation of thrust coefficient, characteristic velocity and specific impulse (sea level, optimum expansion, vacuum)
• Optimization of propellant components mixture ratio for maximum specific impulse of bipropellant systems
• Altitude performance analysis
• Analysis of nozzle performance with respect to overexpansion and flow separation
• Throttled engine performance analysis
• Estimation of test (delivered) nozzle performance
• Read, manipulate and write RPA configuration files
• Available as DLL for Microsoft® Windows™, as well as shared libraries for Apple® Mac OS X and Linux
• Available for both x86 and x86-64 versions of operating systems
