摘要： Flow control in pulse detonation engines is accomplished using magnetohydrodynamic principles. The pulse detonation engine includes a tube having an open forward end and an open aft end and a fuel-air inlet formed in the tube at the forward end. An igniter is disposed in the tube at a location intermediate the forward end and the aft end. A magnetohydrodynamic flow control system is located between the igniter and the fuel-air inlet for controlling detonation in the tube forward of the igniter. The magnetohydrodynamic flow control system utilizes magnetic and electric fields forward of the igniter to dissipate or at least reduce the ignition potential of the forward traveling detonation flame front.

摘要： This invention is a two stroke, regenerated, external combustion, reciprocating engine. Each unit of the engine has cylinder 12 that is closed at one end by cylinder head 4 and contains power piston 18 that is connected to power output shaft 22, and plunger 11 that sucks in fluid and pushes out exhaust. Plunger 11 is a movable wall which has attached to it plunger valve 8 that opens to allow fluid to flow through plunger 11 while plunger 11 is moving away from piston 18, and closes to form a plunger while plunger 11 is moving towards piston 18. Plunger 11 also has attached to it exhaust pipe 7, exhaust valve 6, heater 14, and an alternating flow heat exchanger, called regenerator 10. Means are provided for the introduction of heat into cylinder 12.

摘要： The “Two Stroke Internal Combustion Engine” is a piston engine operated with compression cooled by cooler 17. This is followed by heat addition from heat exchanger high-pressure side 10 at close to constant pressure (the pressure at the end of the heat addition is the same as the pressure at the start of the heat addition). Heat is then added at close to constant volume by burning fuel. This is followed by complete expansion. And finally, heat exchanger low-pressure side 40 transfers heat to heat exchanger high-pressure side 10.

摘要： A system for converting hydrogen into mechanical energy. The system comprises a combustion chamber, an ignition system, and accumulator, a propulsion system, and a control valve. Hydrogen, oxygen, and water are introduced into the combustion chamber. The ignition system ignites a mixture of hydrogen and oxygen in the combustion chamber. A source of working fluid is operatively connected to the combustion chamber such that expanding fluid within the combustion chamber acts on the working fluid to pressurize the working fluid. The accumulator is connected to the combustion chamber such that pressurized fluid within the combustion chamber flows into the accumulator. The propulsion system comprises a cylinder and a piston member arranged within the cylinder. The control valve is connected between the accumulator and the cylinder to control a flow of pressurized working fluid from the accumulator to the cylinder to cause the piston member to move relative to the cylinder.

摘要： This invention relates to air breathing engines, such as ramjets, scramjets and internal combustion, and more particularly to an active combustion control device for a combustor. In more particularity, the present invention relates to a method and apparatus that applies active combustion control technology to advanced propulsion devices and closed-loop fuel injection at sub-harmonic frequencies of the instability frequency of the combustor. The problem of limited actuator frequency response is addressed by injecting fuel pulses at sub-harmonic frequencies of the instability. The fuel may be liquid, solid or gas. To achieve this desired result, a closed loop controller is designed to determine sub-harmonic frequencies using a divider to divide the instability frequency of a combustor, yielding a fraction of the harmonic frequency. Also, this invention also combines open loop injection control with closed loop injection control to obtain enhanced engine performance, which includes extension of the stable combustion zone.

摘要： An auxiliary power system for providing electrical power and heat to an indoor area includes an external combustion engine, such as a Stirling cycle engine, for generating mechanical energy and thermal energy. The external combustion engine burns a fuel with substantially complete combustion such that exhaust emissions from the external combustion engine are below a predetermined exhaust level. A generator is coupled to the external combustion engine and converts the mechanical energy produced by the external combustion engine to electrical power. A first power output is used to provide the electrical power produced by the generator. The external combustion engine and generator are disposed within a housing such that the external combustion engine, generator and housing combination is a portable size. The thermal energy generated by the external combustion engine may be used to heat the atmosphere surrounding the housing.

摘要： A power plant includes a high temperature fuel cell, a volume expansion heat engine producing mechanical energy, and a combustion chamber coupled to receive from said fuel cell at least a portion of unconsumed fuel and apply high pressure combusted gases to the engine. A reformer can feed fuel to said fuel cell. A distributor distributes fuel cell exhaust fuel selectively to the reformer and the combustion chamber and varies the ratio of exhaust fuel fed to the reformer and combustion chamber in accordance with predetermined power desired from said fuel cell and engine.
