ABSTRACT:
There is provided a two-stage system for expelling a liquid fuel component from a main fuel tank to a rocket engine. A pressurized high vapor pressure liquid combined with the vapor of that liquid expel a desired volume of a gas forming liquid from a first stage fuel tank. A gas generator converts this liquid to a gas that expels a desired quantity of fuel from the main fuel tank. The two-stage system is at an equilibrium pressure. The only active control required for the system is a controller to meter the flow of fuel from the main fuel tank to the engine. The pressure drop in the system resulting from the discharge of fuel causes the high vapor pressure liquid to partially evaporate charging more gas into the system until equilibrium is achieved again.
