RocketCEA Wraps The NASA Fortran CEA Code And Provides Some Useful Tools

RocketCEA makes direct calls to the NASA FORTRAN CEA code in “rocket” mode to calculate Isp, Cstar, Tcham etc. and provides tools to help determine useful mixture ratio range, optimum MR and more.

RocketCEA does not use the FORTRAN CEA2.f file directly.

Many modifications have been made in order to wrap CEA with f2py to build a python module.

Additional changes to CEA2.f have been made in order to properly handle hydrazine monopropellant’s ammonia dissociation.

Although the default units in RocketCEA are English units, SI units may be used for both input and output as well. (See Simple Examples > Transport Properties in Docs)

See NASA CEA Documentation: CEA User Manual (NASA RP-1311).pdf and CEA Methodology (NASA RP-1311).pdf

Note

For those interested in using RocketCEA to design rocket thrusters, there are two companion projects RocketIsp and RocketProps.

RocketIsp uses a simplified JANNAF approach to calculate delivered specific impulse (Isp) for liquid rocket thrust chambers.

RocketProps calculates the various liquid propellant properties required to analyse a liquid propellant thrust chamber.

Note

Python 3.8 on Windows has been problematic and is not fully supported.

Python 3.8 64 bit on Windows has been made to work by using the new os.add_dll_directory command to locate MinGW DLL libraries, however, 32 bit python 3.8 is not yet supported.
