A solid fuel propulsion system includes a housing, an air inlet configured to enable air to flow into the housing, an air duct, a rotation detonation chamber, and a nozzle assembly. The air duct is disposed in the housing and is in fluid communication with the air inlet. The air duct is configured to supply air for combustion of a solid fuel configured to sublimate into a gaseous fuel mixture. The rotation detonation chamber is disposed in the housing aft of the air duct and is configured to combust the gaseous fuel mixture and air to generate a rotating detonation wave. The nozzle assembly is configured to expand and exhaust the flow prompted by the rotating detonation wave to generate thrust.

A fuel reformation system includes a fuel delivery system that supports fuel, an oxidizer delivery system that supports an oxidizer, a mixer/vaporizer system in fluid communication with the fuel delivery system and the oxidizer delivery system, and a fuel processing reactor system. The mixer/vaporizer system receives the oxidizer from the oxidizer delivery system and the fuel from the fuel delivery system to mix and vaporize the oxidizer and fuel into a first effluent. The fuel processing reactor system receives the first effluent and reacts with the first effluent to generate a second effluent in the form of hot syngas for selective injection into a high speed, air-breathing propulsion system.

Fuel reformation for use in high speed propulsion systems

A low-emission and environmentally-friendly apparatus and method is used to generate a high-pressure stream of thermal vapor. The thermal vapor stream may be injected into a subsurface petroleum-bearing formation for recovery of highly viscous petroleum or used to turn a steam turbine for driving an electrical generator. In one implementation, the high-pressure stream of thermal vapor is generated by burning a high-temperature fuel, including any short or long chain hydrocarbon products from methane to coal, in an enclosed vessel to produce combustion gases. Various cooling techniques, including regenerative cooling, may be employed to maintain the internal temperature of the vessel below a predefined safe level. The high-pressure thermal vapor stream may then be used to enhance recovery of highly viscous petroleum.

Thermal vapor stream apparatus and method

A fuel reformulation system for an engine comprising an annular body for a flow of fluids therethrough connected to the engine, a source of fuel for flowing through at least a portion of the annular body, and a catalytic member connected to the annular body for the flow of any fluids thereacross from the annular body.

Fuel reformulation systems

A scramjet has a cowl, a center structure, and a plurality of wide pylons connecting the cowl to the center structure, with scramjet engines positioned between adjacent pylons. Leading surfaces of adjacent pylons converge to one another to provide side wall compression to air entering the engines. The center structure includes a fore body, a center body and an aft body that, with the pylons, define a basic structure either formed entirely from one piece or several securely connected pieces. A method of testing the scramjet projectile comprises using a gun to accelerate the scramjet projectile to the takeover velocity of the engines.
