F02K 7/10

US Classification:

244 53B, 60768

Abstract:

Hypersonic inlet systems and methods are disclosed. In one embodiment, an inlet for an airbreathing propulsion system includes an inboard surface at least partially shaped to conform to a plurality of streamline-traces of a design flowfield approaching an aperture, an outboard surface spaced apart from the inboard surface, an upper surface extending between the inboard and outboard surfaces, and a lower surface extending between the inboard and outboard surfaces, wherein leading edges of the inboard, outboard, upper, and lower surfaces cooperatively define the aperture.

US Classification:

429 17, 423579, 4236582, 422162, 429 20

Abstract:

Methods and systems of providing a source of hydrogen and oxygen with high volumetric energy density, as well as a power systems useful in non-air breathing engines such as those in, for example, submersible vehicles, is disclosed. A hydride reactor may be utilized in forming hydrogen from a metal hydride and a peroxide reactor may be utilized in forming oxygen from hydrogen peroxide. The high temperature hydrogen and oxygen may be converted to water using a solid oxide fuel cell, which serves as a power source. The power generation system may have an increased energy density in comparison to conventional batteries. Heat produced by exothermic reactions in the hydride reactor and the peroxide reactor may be transferred and utilized in other aspects of the power generation system. High temperature water produced during by the peroxide reactor may be used to fuel the hydride reactor.

US Classification:

422198, 422222, 29428

Abstract:

Apparatus and methods for the production of hydrogen using a reformer including a housing, a first plate having a first plurality of fin structures and a second plate having a second plurality of fin structures assembled such that the first plurality of fin structures is interleaved with the second plurality of fin structures. At least one inlet port is formed in at least one of the first plate and the second plate, and at least one outlet port formed in at least one of the first plate and the second plate. The fin structures may be coated with a catalytic material to enhance or stimulate reactions taking place within the apparatus. A heat exchange device may also be integrated into one or both plates of the reformer.
