    摘要： An air-breathing pulsed jet engine for aircraft propulsion which employs a piston compressor rather than much more expensive axial or centrifugal compressors and turbines employed by conventional turbojet engines. The engine is similar to the common two-cycle gasoline engine, except its cylinder head comprises a jet nozzle with an internal pressure-activated nozzle-blocking valve. A spring keeps this valve closed during the engine's compression stroke when the piston, connected to a crankshaft and flywheels by a connecting rod, is forced by the moment-of-inertia of the flywheels toward the cylinder head. When ignition and combustion of the compressed air and fuel occurs slightly before the piston reaches the top of its stroke, the much greater pressures within the engine's combustion chamber force the valve to pivot open. This allows a jet of combustion gases to be released through the jet nozzle into the atmosphere. The reactive forces of the gas jet work against the piston to produce linear thrust (due to the moment-of-inertia of the flywheels) and to store up energy in the flywheels to motivate the piston through the next compression stroke. The jet pulse continues until the pressure inside the combustion chamber drops to a predetermined level, when the spring is able to close the valve. Since the pressures inside the combustion chamber of a gasoline engine are on the order of those inside many rocket motors, the thrusts imparted to the engine during each jet pulse is substantial.

    摘要翻译： 一种用于飞行器推进的呼吸脉冲喷气发动机，其使用活塞式压缩机，而不是由常规涡轮喷气发动机采用的更昂贵的轴向或离心压缩机和涡轮机。 发动机类似于普通的双循环汽油发动机，除了其气缸盖包括具有内部压力激活喷嘴截止阀的喷嘴。 当发动机的压缩冲程中，当通过连接杆连接到曲轴和飞轮的活塞被飞轮的惯性矩向气缸盖强制时，弹簧保持该阀关闭。 当压缩空气和燃料的点燃和燃烧在活塞到达其行程的顶部之前稍微发生时，发动机的燃烧室内的更大的压力迫使阀枢转打开。 这使得燃烧气体的喷射通过喷嘴释放到大气中。 气体射流的反作用力对活塞产生线性推力（由于飞轮的惯性矩），并且在飞轮中储存能量以通过下一个压缩冲程来激励活塞。 当弹簧能够关闭阀时，喷射脉冲持续直到燃烧室内的压力下降到预定水平。 由于汽油发动机的燃烧室内的压力是许多火箭发动机内的压力，因此在每个喷射脉冲期间赋予发动机的推力是显着的。

    摘要： A pulse detonation engine is provided with several detonation combustors selectively coupled to an air inlet and fuel source by a rotary valve. The rotary valve isolates the steady operation of the air inlet and fuel system from the unsteady nature of the detonation process, and allows the fueling of some of the detonation chambers while detonation occurs in other detonation chambers. The fuel system may use a solid fueled gas generator.

    摘要： The invention consists of an engine that converts hydrothermomechanical energy into thrust. There is but a single internal moving part . . . the piston. When in operation, the piston preforms two distinct functions: (1) as a valve allowing intermittent injection of a fuel/air mixture for combustion and (2) as a hydraulic fluid pump. Resultant chemical reactions in the combustion chamber produces intermittent high velocity gases at the exit nozzle of the said engine, which provides sufficient thrust for subsonic and sonic aircraft operations. The intermittent thermal activity and specific manner of braking action of the hydraulic fluid, causes the said piston to function as a hydraulic fluid pump. Thereby providing mechanical energy to power cranes, pumps, compressors, generators, etc., etc., and, or provide impetus for aquatic craft and ground vehicles.
