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.
