Reusable full-cycle liquid methane and reusable liquid oxygen engine has a specific impulse (Isp) muito alto, able to produce a large amount of thrust relative to the amount of fuel consumed with a combustion chamber of about 1 meter in diameter with closed fuel cycle, in which liquid methane is used as fuel and liquid oxygen as oxidizer cycle allowing a higher thermal efficiency and less accumulation of waste.
