    摘要: In an underwater vehicle, hydrogen and oxygen are fed into a combustion chamber of a combustor of the underwater vehicle to initiate a combustion reaction, which generates high-pressure steam. The high-pressure steam can be cooled with the injection of seawater, and can be condensed into high-pressure water by the addition of sufficient seawater. High-pressure water is then ejected out of the combustor, generating thrust for the underwater vehicle. Sensors that measure the combustor pressure and the external pressure could be used to adjust the combustor pressure, allowing for constant velocity as the depth of the underwater vehicle changes. Alternatively, the sensors could adjust the area of an exit nozzle of the combustor. Stored water can be converted back into hydrogen and oxygen by using electrical power external to the system. After regeneration of the water into hydrogen and oxygen, the propulsion system would be ready for operation again.

    摘要: A closed-loop cooling system is provided for a hydrogen/oxygen based combustor. A combustion reaction between hydrogen and oxygen in the combustor produces steam. The steam is used to generate work from a turbine shaft, which is used to drive a propulsion system for the underwater vessel. After the steam passes through the turbine, the steam is cooled back to liquid water by a condenser that uses a seawater cooling loop to cool the steam into cold water. The cold water is then injected into the combustor, and pumped into passages along the walls of the combustor, thus absorbing the heat. The cold water absorbs this heat until it becomes hot water or steam, which is then injected into the combustor with the hydrogen and oxygen to act as a diluent, thus reducing the reaction temperature of the hydrogen/oxygen combustion reaction. The reaction produces more steam, and the cycle repeats.

    摘要: A regenerative fuel cell is combined with a combustion engine such as a Pulse Detonation Engine (PDE) to create a closed-loop power generation system. Stored hydrogen and oxygen are used by the regenerative fuel cell, and by the combustion engine, in which the reaction of the hydrogen and oxygen produces water in the gas phase (steam). The steam is used to generate work from a turbine shaft, which is used to drive a propulsion system for the marine vessel. After the steam passes through the turbine, the steam is cooled back to liquid water by a condenser, and stored with the water produced by the regenerative fuel cell. The stored water can be converted back into hydrogen and oxygen by using electrical power external to the closed-loop system. After regeneration of the water into hydrogen and oxygen, the closed-loop power system would be ready for operation again.

The reheating device is configured to introduce a second fuel stream in a transverse direction to a working gas stream from the first turbine for combusting the fuel in presence of the working gas stream. The gas turbine system also includes a second turbine configured to expand an exit gas stream from the reheating device.

    摘要: A fuel nozzle device suitable for use in a gas turbine engine or the like is provided. The fuel nozzle device includes a fuel line and a plurality of gas orifices disposed at a downstream end of the fuel line, the plurality of gas orifices operable for injecting fuel into an air stream. The acoustic resistance of each of the plurality of gas orifices is chosen to match the acoustic impedance of the fuel line such that the maximum acoustic energy may be transferred between the fuel nozzle device and the combustor, thus enhancing the ability of the fuel nozzle device to control the combustion dynamics of the gas turbine engine system. A fuel injection resonator assembly suitable for use in a gas turbine engine or the like is also provided. The fuel injection resonator assembly includes a plurality of orifices separated by a variable length tube. The area ratio of the plurality of orifices may be adjusted using an automated valve system or the like to modify and/or control the relative flow resistance of the plurality of orifices. The resulting fuel injection resonator assembly acts as a tunable acoustic waveguide operable for delivering fuel to the combustor.
