A system and methods are provided for combining systems of an upper stage space launch vehicle for enhancing the operation of the space vehicle. Hydrogen and oxygen already on board as propellant for the upper stage rockets is also used for other upper stage functions to include propellant tank pressurization, attitude control, vehicle settling, and electrical requirements. Specifically, gases from the propellant tanks, instead of being dumped overboard, are used as fuel and oxidizer to power an internal combustion engine that produces mechanical power f...
1. An upper stage launch vehicle comprising: a pair of main vehicle tanks for storage of liquid propellants therein including a hydrogen tank and an oxygen tank;at least one main upper stage rocket for propelling the launch vehicle in space;a payload associated with said launch vehicle;an internal combustion engine powered by waste ullage hydrogen and oxygen vented from said tanks;a power generator communicating with an output shaft of said internal combustion engine for generating electrical current;a battery in electrical communication with said genera...
