Abstract: A unique seal for a wave rotor disk engine is disclosed herein. The seal is operable for sealing a region between a rotor and a rotor casing. The seal is spring loaded and will engage with the tip of the rotor to reduce pressure loss within the wave rotor disk engine.

Abstract: This invention is for a hydrogen generation system using a wave reformer in which shock and expansion waves are created in a manner causing head-on colliding shock waves and multi-stage compression where reacting gases within the wave reformer are heated and compressed to thermally crack or decompose one or more fuel sources, such as hydrocarbon fuels, to generate a fuel product containing hydrogen, where the internal configuration of channels within the wave reformer are defined by a shaped portion along a length thereof.

Abstract: An improved power generation system for aircraft and methods of its operation are provided, wherein the system combines a wave reformer providing a contiguous fuel supply to a jet engine, and use of ammonia as the fuel source from which hydrogen and/or a duel supply of ammonia and hydrogen will be supplied to aircraft jet engines leading to a higher thermal efficiency than existing engines with low to no direct emission footprint.

Abstract: An improved power generation system and methods of its operation are provided, wherein the system combines: (i) a wave reformer, (ii) an optional second wave rotor, and (iii) a gas turbine in a flexible range of novel designs. Such a hybrid power generation system can thermally crack or decompose hydrocarbon fuel to produce a high-pressure fuel product, including mainly hydrogen and lead to a higher thermal efficiency than existing engines with low to no direct emission footprint.
