A HAN TEAN mixing gas generator pressurization system is proposed for use on pressure-fed rockets. HAN (hydroxyl ammonium nitrate) and TEAN (triethanol ammonium nitrate) are salts dissolved in water to form a single liquid propellant. Combustion of HAN TEAN results in water, carbon dioxide, and nitrogen at high temperatures and pressures. A cryogenic primary working fluid is mixed the HAN TEAN exhaust products to provide warm high-pressure gas to pressurize the rocket's main propellant tanks.

[ I claim:] [1.] A method to pressurize a pressure-fed liquid rocket's main propellant tanks, the method comprising:a. providing a supply of HAN TEAN liquid propellant and a supply of a cryogenic or water working fluid in tanks, both tanks maintained at a high pressure level through a common high pressure source;b. injecting the HAN TEAN into a gas generator combustion chamber and igniting it, whereby the liquid propellant is combusted yielding high temperature exhaust products of water, carbon dioxide, and nitrogen;c. passing the HAN TEAN exhaust products through a sonic nozzle;d. providing a manifold at the exit end of the sonic nozzle into which the working fluid is injected to thereby change the working fluid phase to a gas;e. mixing said working fluid gas with the HAN TEAN exhaust products to thereby creating a high-pressure warm gas mixture; andf. directing said gas mixture to the main propellant tanks of the rocket.
