    摘要: The present invention is a pulse detonation combustion system, having a plurality of detonation initiation devices coupled to a main combustion chamber, where each of the detonation initiation devices is operating out-of-phase with each other. Each of the detonation initiation devices assists in the initiation of a detonation in the main combustion chamber, out-of-phase from each other such that the operational frequency of the pulse detonation combustion system is related to the number of detonation initiation devices multiplied by the operational frequency of a single detonation initiation device.

    摘要: In the present invention, at least one detonation initiator is positioned downstream of a main combustion chamber, with the initiator oriented such that it projects a detonation initiation wave forward into the main combustion chamber. The main combustion chamber contains a wave reflection surface. The detonation initiation wave is directed into the main combustion chamber and at the wave reflector surface and is used to initiate, or assist in the initiation of, a fuel and gas mixture in the main combustion chamber. The fuel and gas mixture is detonated, creating a high temperature and high pressure wave that is directed out of the main combustion chamber.

    摘要: A pulse detonation combustor is provided with a fuel-air mixer located upstream from a detonation chamber. A fuel-air mixture exits the fuel-air mixer and enters the detonation chamber, where it is ignited by an ignition source. The flow from the fuel-air mixer passes over the surface of a center body, which extends downstream from the fuel-air mixer. The surface of the center body contains at least one turbulence generator, which imparts additional turbulence in the fuel-air mixture passing through the chamber. The turbulence generator aids in the mixing of the fuel and air of the fuel-air mixture to enhance the deflagration to detonation transition within the pulse detonation combustor.

    摘要: A swirler having cross-sectional area comparable to the area of a detonation chamber is placed upstream of the detonation chamber to enhance the fuel-air mixing. The swirler has a first region and a second region, each of which induces swirl in the flow through the swirler. Each region induces a different direction of swirl in the flow. The residual net swirl present in the flow downstream of the swirler is controlled by the relative properties of each region of the swirler. The swirler also provides high optical blockage to inhibit the upstream propagation of flow due to the detonation shockwave.

    摘要: A two-stage pulse detonation system includes a pre-combustor and a geometric resonator connected via a converging-diverging nozzle to the pre-combustor to create a high temperature and high pressure conditions in the resonator in order to create optimal conditions for detonation initiation. A mixture of a fuel and a gas is burned in the pre-combustor and is passed through the nozzle into the geometric resonator, where the burned mixture is detonated. The detonation propagates through the resonator exit nozzle thus generating thrust.
