Abstract
A system for providing ignition and pressurization of hypersonic vehicles is disclosed. The system combines the pressurization, barbotage and ignition functions into a single system saving mass and volume and simplifying the hypersonic vehicle plumbing. A monopropellant fuel such as Tridyne is used to pressurize a fuel tank, warm the fuel as it enters fuel injectors, and provide barbotage of the fuel just prior to its injection into a combustion chamber.
Claims16
A hypersonic ignition system, comprising:
- a first tank for holding a hydrocarbon fuel;
- a plurality of fuel injectors for injecting the hydrocarbon fuel into a combustion chamber;
- a second tank for holding a Tridyne gas;
- a catalyst bed operatively coupled to the second tank for reacting with and warming the Tridyne gas;
- a pressurization system operatively coupled to the catalyst bed for using the warmed Tridyne gas to pressurize the first tank;
- and
- an ignition and barbotage system operatively coupled to the catalyst bed for providing warmed Tridyne gas to the plurality of fuel injectors.
