    摘要: Disclosed herein are several embodiments of rotors (gears) which utilize spherical involute curves to determine the surfaces of the lobes (teeth). In some embodiments the contact surfaces are radial projections of spherical involute surfaces. In other embodiments the contact surfaces have a root and/or tip of a spherical involute curve, but are barreled or otherwise curved to reduce the point stress on each rotor. The rotors may also be configured where torque transfer is provided at a first set of lobes (teeth) and backlash removal is provided on teeth radially opposed to the first set of lobes (teeth). As the apparatus rotates, the position of torque transfer remains substantially the same, as does backlash prevention/removal, but the teeth providing these operations vary. The rotors may also be used for fluid flow.

    摘要: A pressure gain combustor comprises a detonation chamber, a pre-combustion chamber, an oxidant swirl generator, an expansion-deflection (E-D) nozzle, and an ignition source. The detonation chamber has an upstream intake end and a downstream discharge end, and is configured to allow a supersonic combustion event to propagate therethrough. The pre-combustion chamber has a downstream end in fluid communication with the detonation chamber intake end, an upstream end in communication with a fuel delivery pathway, and a circumferential perimeter between the upstream and downstream ends with an annular opening in communication with an annular oxidant delivery pathway. The oxidant swirl generator is located in the oxidant delivery pathway and comprises vanes configured to cause oxidant flowing past the vanes to flow tangentially into the pre-combustion chamber thereby creating a high swirl velocity zone around the annular opening and a low swirl velocity zone in a central portion of the pre-combustion chamber. The E-D nozzle is positioned in between the pre-combustion chamber and detonation chamber and provides a diffusive fluid pathway therebetween. The ignition source is in communication with the low swirl velocity zone of the pre-combustion chamber. This configuration is expected to provide a combustor with a relatively low total run-up DDT distance and time, thereby enabling high operating frequencies and corresponding high combustor performance.

    摘要: Disclosed herein is a valveless multitube pulse detonation engine including: a plurality of detonation tubes, wherein each detonation tube comprises an independent discharge outlet, and the plurality of detonation tubes interconnected at a common air/fuel mixture intake port. In the disclosed engine, an air and fuel mixture is detonated in the detonation tubes simultaneously, and the common air/fuel mixture intake port minimizes back-pressure caused by detonating the air/fuel mixture by directing multiple reverse shock waves into one another and effectively using the back-pressures as reacting surfaces for one another and effectively reducing the effect of back flowing shock waves moving towards upstream. The detonation tubes may be non-linear, and may have independent discharges. The independent discharges may be coupled to an adapter nozzle terminating in a combined exhaust outlet.

    摘要: Provided herein are multiple variations, applications, and variations for producing electrical power from a flowing fluid such as a gas or liquid under pressure, for example natural gas flowing through a pipeline, by means of one or more positive displacement devices that drive one or more electrical generators. The electrical generators may be immersed in the flow stream together with the positive displacement devices as disclosed, or alternately may be isolated from the flow stream, such as by magnetic coupling, in order to promote longevity and to decrease the risk of accidental discharge or explosion of the fluid in the flow stream. To further decrease such risks, the positive displacement devices may isolate the drive fluid from the environment without the use of dynamic seals.
