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)
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.
On Windows, 32 bit python 3.8 and above are not supported.
As of this writing (10/5/2021) 64 bit python 3.10 requires Unofficial Binaries to install numpy, scipy and matplotlib.
