摘要： The invention provides a liquid fueled pulsed detonation air breathing engine. The engine has at least one, and preferably a multiplicity of, detonation chambers, each of which has an inlet end for opening and receiving a charge of fuel and air, and an outlet end for discharging combustion product gases. A fast-acting valve is located above the inlet ends of the detonation chambers and cyclically opens the fuel and air receiving openings in the inlet ends of the detonation chambers to allow a fuel/air charge to enter the chambers. In a preferred embodiment, the valve is of a rotary type with a body that has at least one opening through which fuel and air can flow into the inlet end of the detonation chamber. Once the valve has closed, detonation is initiated by an ignitor and impulse force is provided by the resultant shock wave. Thereafter, the valve opens again so that the detonation chamber can be charged with fuel and air to recommence the cycle. The invention also provides an embodiment of an engine that has both inlet and outlet valves. These valves operate out of phase so that when the inlet valve is open to receive fuel and air into the detonation chamber, the outlet valve is closed. When detonation commences, the outlet valve is open and the inlet valve is closed. Optionally, a source of oxygen allows a stratified charge in the engine to enhance detonation. Also provided is a control system (48) for sensing the position of the valves, (58, 80) and using this sensed position to inject fuel, inject oxygen and ignite the fuel and air mixture.
摘要翻译： 本发明提供一种液体燃料脉冲爆震空气呼吸发动机。 发动机具有至少一个，优选地是多个爆轰室，每个都具有用于打开和接收燃料和空气的进料口的入口端，以及用于排出燃烧产物气体的出口端。 快速作用阀位于引爆室的入口端上方，并循环地打开引爆室入口端的燃料和空气接收孔，以允许燃料/空气进入腔室。 在优选实施例中，阀是具有主体的旋转型，其具有至少一个开口，燃料和空气可以通过该开口流入爆炸室的入口端。 一旦阀门关闭，爆震就由点火器启动，冲击力由所产生的冲击波提供。 此后，阀再次打开，使得引爆室可以充入燃料和空气以重新开始循环。 本发明还提供了具有入口和出口阀的发动机的实施例。 这些阀门异相工作，因此当入口阀打开以接收燃料和空气进入爆轰室时，出口阀关闭。 当爆炸开始时，出口阀打开，进气阀关闭。 可选地，氧源允许发动机中的分层装料增强爆震。 还提供了一种用于感测阀（58,80）的位置并使用该感测位置喷射燃料，注入氧气并点燃燃料和空气混合物的控制系统（48）。

摘要： A pulse detonation rocket engine, having at least two detonation chambers. The rocket propelled vehicle includes at least one fuel delivery system in fluid communication with each of the at least two detonation chambers, and at least one oxidant delivery system in fluid communication with the detonation chambers, along with fast-acting valves to inject fuel and oxidant controlledly into the chambers. An ignitor in each of the detonation chambers intermittently initiates detonation of a fuel and oxidant mixture in the chamber, in a controlled cycle, to provide motive force. Also provided is a combined cycle engine, able to operate in air breathing mode, oxidant augmented mode, and as a rocket engine. The combined cycle engine includes at least one detonation chamber, and may include a plurality of such chambers. The invention further provides methods of intermittently detonating sequentially created fuel and oxygen mixtures in these engines, and methods of using these engines.

摘要： Methods and apparatus are provided for cleaning a surface within a vessel. A fuel/oxidizer charge is provided within a combustion conduit. An initial deflagration commenced in a first portion of the charge produces a final detonation at least in another portion of the charge to expel a shockwave from the conduit which impinges upon the surface. The deflagration-to-detonation transition may be encouraged by mechanical enhancements and/or by making the first charge portion more detonable than the second.

摘要： A nozzle for a detonative combustion engine, the engine having multiple combustor tubes, comprises a common plenum communicating with the combustor tubes. The common plenum combines separate exhaust streams from the combustor tubes into a compound subsonic exhaust stream. A compound flow throat communicates with the common plenum. The compound flow throat converts the compound subsonic exhaust stream into a compound sonic exhaust stream. The common plenum and compound flow throat cooperate to maintain a predetermined upstream combustor pressure regardless of down stream pressure exiting the expansion section. Optionally, an interface section is inserted between the plenum and the engine such that it communicates with the common plenum section and with outlets of the combustor tubes. The interface section is compartmentalized into flow passages with each flow passage having a cross-sectional area that increases from that of a particular nozzle intake port connected to a conductor tube exit. Additionally, an expansion section communicates with the outlet of the compound flow throat and has a diameter greater than the diameter of the compound flow throat. The expansion section converts the compound sonic exhaust stream into a compound supersonic exhaust stream thus expanding the exhaust stream to predetermined lower pressure.
