    摘要： A detonation combustion system includes a detonation combustor. The detonation combustor includes a detonation manifold and one or more detonation chamber walls defining a detonation chamber. The detonation manifold includes a plurality of detonation fluid pathways defined by a monolithic structure of the detonation manifold, and a plurality of detonation orifice groups respectively including a plurality of detonation orifices disposed about a surface of the detonation manifold. Respective ones of the plurality of detonation orifice groups provide fluid communication from a corresponding one of the plurality of detonation fluid pathways to the detonation chamber through the plurality of detonation orifices corresponding to the respective one of the plurality of detonation orifice groups. The plurality of detonation orifices may be symmetrically oriented about a reference element of the detonation combustor.

    摘要： A fuel injector to reduce NOx emissions in a combustor system. The fuel injector including a housing, at least one oxidizer flow path, extending axially through the fuel injector housing and defining therein one or more oxidizer flow paths for an oxidizer stream and a fuel manifold, extending axially through the fuel injector housing and defining therein one or more fuel flow path. The fuel manifold includes a forward portion and an aft portion including an aft face. A plurality of fuel injector outlets are defined in the aft portion, wherein the plurality of fuel injector outlets are configured to inject a fuel flow along a mid-plane of the fuel injector and away from a downstream wall. The fuel flow exiting the fuel manifold undergoes circumferential and radial mixing upon interaction with the oxidizer stream. Additionally disclosed is a combustor system including the fuel injector.

    摘要： Systems for rotating detonation combustion are provided herein. The system includes an inner wall and an outer wall each extended around a centerline axis, wherein a detonation chamber is defined between the inner wall and the outer wall, and an iterative structure positioned at one or both of the inner wall or the outer wall. The iterative structure includes a first threshold structure corresponding to a first pressure wave attenuation and a second threshold structure corresponding to a second pressure wave attenuation. The iterative structure provides for pressure wave strengthening along a first circumferential direction in the detonation chamber or pressure wave weakening along a second circumferential direction opposite of the first circumferential direction. The first circumferential direction corresponds to a desired direction of pressure wave propagation in the detonation chamber.
