Hybrid internal detonation-gas turbine engines incorporating detonation or pulse engine technology (such as an internal detonation engine), and methods of manufacturing and using the same are disclosed. The internal detonation engine includes a detonation chamber having a fuel igniter therein, a stator at one end of the detonation chamber having at least a first opening to receive fuel, a rotor adjacent to the stator, and an energy transfer mechanism configured to convert energy from igniting or detonating the fuel to mechanical energy. The detonation chamber and fuel igniter are configured to ignite or detonate a fuel in the detonation chamber. Either the stator or the detonation chamber has a second opening to exhaust detonation gas(es). The rotor has one or more third openings therein configured to overlap with at least the first opening as the rotor rotates.

The subject of the present invention is a combustion turbine (1) for intermittent combustion with at least one combustion chamber (3) having inlet valves (2) and an ignition device (18), the at least one combustion chamber (3) having no shut-off devices on the off-gas side and being thus open on the off-gas side at all times. Downstream of the at least one combustion chamber (3), a turbine (4), which can be impinged with process gas obtained in the combustion chamber (3), is positioned, with a flow-through chamber (5) being positioned between the at least one combustion chamber (3) and the turbine (4) axially behind the at least one combustion chamber (3). The flow-through chamber (5) is separated from the at least one combustion chamber (3) by a guiding plate (6) or a further turbine (7).The subject of the present invention is furthermore a process for operation of a combustion turbine (1) and a drive system for a machine having as its core a combustion turbine (1) according to the invention.

An engine contains a compressor stage, a plurality of pulse detonation combustors and a rotary inlet valve structure having a plurality of inlet ports through which at least air flows to enter the pulse detonation combustors during operation of the engine. Downstream of the pulse detonation combustors is a turbine stage. Further, the ratio of the pulse detonation combustors to the inlet ports is a non-integer.

A system of controlling airflow into a pulse detonation engine includes a rotary airflow controller valve receiving air from a high-speed inlet. An engine frame includes a plurality of detonation chambers. A sealing mechanism is between the rotary airflow controller valve and the engine frame. The sealing mechanism is associated with the engine frame and limits leakage of a gas from a first of the detonation chambers to a second of the detonation chambers.

A pulse detonation engine contains a mechanically driven timing device coupled with a stator device, where the timing device has both an opening portion and a blocking portion. The opening and blocking portions open and close air flow access to a detonation chamber of the pulse detonation engine at appropriate times during the pulse detonation cycle.

A pulse detonation system for a gas turbine engine having a longitudinal centerline axis extending therethrough includes a rotatable cylindrical member having a forward surface, an aft surface, and an outer circumferential surface, where a plurality of spaced detonation passages are disposed therethrough. Each detonation passage includes at least a portion having a longitudinal axis extending therethrough oriented at a circumferential angle to the longitudinal centerline axis. The pulse detonation system further includes a shaft rotatably connected to the cylindrical member and a stator configured in spaced arrangement with the forward surface of the cylindrical member and a portion of the shaft. The stator has at least one group of ports formed therein alignable with the detonation passages as the cylindrical member rotates. In this way, detonation cycles are performed in the detonation passages so that combustion gases exit the aft surface of the cylindrical member to create a torque which causes the cylindrical member to rotate. Each detonation passage further includes a first end located adjacent the forward surface of the cylindrical member and a second end located adjacent the aft surface of the cylindrical member.
摘要:
A closed pressure housing is provided having an internal partition dividing the interior of the housing into first and second chambers. The first chamber includes a pressurized gas inlet and a liquid fuel reservoir is disposed within and opens into the interior of the first chamber. Fuel supply means is provided for supplying liquid fuel under pressure to the fuel reservoir and structure is operatively associated with the fuel reservoir for heating the latter and vaporizing the liquid fuel therein. A combustion gas transfer passage communicates the first and second chambers and is controlled by a check valve and ignition means is provided within the first chamber for igniting a combustible mixture of pressurized gas and vaporized fuel within the first chamber. Finally, the second chamber includes a combustion gas outlet and the effective flow rate of the combustion gas outlet is less than the effective flow rate of the gas pressure transfer passage. Accordingly, the second chamber acts as a pressure accumulator for modulating pressure pulses discharged through the transfer passage from the first chamber into the second chamber and a reasonably high pressure of combustion gases is maintained within the second chamber, even though the combustion of gas and vaporized fuel within the first chamber occurs intermittently.
