rocketcea 1.1.18+dfsg-3 (armhf binary) in ubuntu lunar

 RocketCEA makes direct calls to a modified copy of 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.
 .
 The modifications to CEA2.f have been made in order to properly handle
 hydrazine monopropellant’s ammonia dissociation.
 .
 A typical use of this program would be to help determine input values for a
 rocket motor burn simulation program.
