Abstract:

The new injection system provides rapid, high pressure, high density, and transient batch injection of cryogenic liquids. The system stores and maintains the temperature of liquids in vacuum jacketed tanks, increases pressures using pumps, and stores the high pressure fluid in accumulators. The accumulator periodically injects the fluids at high pressure in measured mass batches into a combustion chamber. The system injects enough liquid or gas in 0. 5 to 3. 0 seconds to provide 500 to 6500 psi in a closed chamber.
