Abstract
A pulse detonation combustor (PDC) assembly includes an upstream chamber forming an inlet plenum, a downstream chamber including a downstream portion of at least one PDC tube, and an integrated PDC head coupled to the upstream chamber and the downstream chamber. The integrated PDC head is configured to facilitate fuel injection and ignition within the PDC tube. The PDC tube includes an inner seal surface and an outer seal surface configured to mate with the inner seal surface, wherein the inner seal surface includes an elevated section thereon that engages with the outer seal surface such that the PDC tube is free to partially pivot about a longitudinal axis thereof.
Claims17
A pulse detonation combustor (PDC) assembly, comprising:
- an upstream chamber including a primary air inlet and a secondary air inlet, the primary air inlet configured to allow primary air to be directed to a primary air plenum, the secondary air inlet configured to allow secondary air to be directed to a secondary air plenum;
- a downstream chamber including a downstream portion of at least one PDC tube, the downstream chamber in flow communication with the primary air plenum to allow primary air to flow into the at least one PDC tube, the downstream chamber further including a cooling plenum in flow communication with the secondary air plenum to allow secondary air to cool the downstream chamber;
- and
- an integrated PDC head coupled to said upstream chamber and said downstream chamber, said integrated PDC head configured to facilitate fuel injection and ignition within said at least one PDC tube.
A pulse detonation combustor (PDC) tube, comprising:
- an inner seal surface;
- and
- an outer seal surface configured to mate with said inner seal surface wherein the PDC tube is used within a pulse detonation combustor;
- and
- wherein said inner seal surface includes an elevated section thereon that increases an outside diameter of said inner seal surface, the outside diameter of said inner seal surface being slightly less than an inside diameter of said outer seal surface such that the PDC tube is free to partially pivot about a longitudinal axis thereof.
A pulse detonation engine (PDE), comprising:
- a pulse detonation combustor (PDC) assembly in communication with an axial flow turbine assembly, said PDC assembly further comprising:
- an upstream chamber including a primary air inlet and a secondary air inlet, the primary air inlet configured to allow primary air to be directed to a primary air plenum, the secondary air inlet configured to allow secondary air to be directed to a secondary air plenum;
- a downstream chamber including a downstream portion of at least one PDC tube, the downstream chamber in flow communication with the primary air plenum to allow primary air to flow into the at least one PDC tube, the downstream chamber further including a cooling plenum in flow communication with the secondary air plenum to allow secondary air to cool the downstream chamber;
- and
- an integrated PDC head coupled to said upstream chamber and said downstream chamber, said integrated PDC head configured to facilitate fuel injection and ignition within said at least one PDC tube.
