Abstract: Separate pressure vessels for oxidizer and fuel components in a combustion/decomposition system add weight and complexity to the system. The fuel and oxidizer can be pre-mixed within a single pressure vessel, but can be unacceptably volatile in a mixed configuration. Providing separate fuel and oxidizer compartments within a singular pressure vessel reduces the weight and complexity of the system, while maintaining the non-volatility of separately stored fuel and oxidizer. The fuel and oxidizer can be selectively mixed within the pressure vessel when desired.

Abstract: The fluids and heat transfer theory for regenerative cooling of a rocket combustion chamber with a porous media coolant jacket is presented. This model is useful for calculating temperature distributions in a coolant fluid and combustion chamber or heat source as well as the associated fluid pressure drop through the coolant jacket. This model for fluids and heat transfer theory can be used to design a regeneratively cooled rocket engine.

Abstract: The presently disclosed technology relates to carbon-on-carbon (C/C) manufacturing techniques and the resulting C/C products. One aspect of the manufacturing techniques disclosed herein utilizes two distinct curing operations that occur at different times and/or using different temperatures. The resulting C/C products are substantially non-porous, even though the curing operation(s) substantially gasify a liquid carbon-entrained filler material that saturates a carbon fabric that makes up the C/C products.

Abstract: The presently disclosed linear detonation wave diverter provides a structure and method for quickly and controllably venting a detonation event out of the diverter without igniting working fluid upstream of a microporous barrier within the linear detonation wave diverter. Further, the detonation wave is linearly vented out of the diverter upon the failure of a burst member, which provides a low resistance path for detonation waves to exit the detonation wave diverter.

Abstract: The presently disclosed technology relates to using a combustion/decomposition heater fed by a working fluid stored within a storage tank to thermally pressurize the storage tank. The thermal pressurization may be used to maintain a desired pressure within the storage tank, even as the working fluid within the storage tank is drawn down. Further, a feedback mechanism may also be incorporated that varies the thermal energy added to the working fluid within the storage tank to maintain the desired pressure within the storage tank.
