Patents by Inventor Charlie Carson

Charlie Carson has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10907824
    Abstract: A fuel split control arrangement is provided. The arrangement includes a staged cooling flow control valve and cooling check valve. The staged cooling flow control valve and cooling check valve is connected between the primary and secondary tips of a nozzle in a turbine engine. The staged cooling flow control valve and cooling check valve includes a valve member arrangement operable to prevent fuel flow from the secondary fuel supply manifold to the secondary tip and simultaneously allow fuel flow from the secondary fuel supply manifold to the primary tip such that the primary tip receives fuel flow from both the secondary fuel supply manifold and the primary fuel supply manifold.
    Type: Grant

  • Patent number: 9574448
    Abstract: A split control unit in a distributed flow unit includes a flow inlet configured to receive a fuel flow, a first manifold having flow lines to supply fuel to one or more primary nozzles, and a second manifold having flow lines to supply fuel to one or more secondary nozzles. In an embodiment, the second manifold is in fluid communication with the flow inlet. A metering valve has a first port in fluid communication with the flow inlet and with the second manifold. The metering valve is configured to supply a metered fuel flow to the first manifold. A flow passage is in fluid communication with, and runs between, a flow line of the first manifold and a flow line of the second manifold to allow for a continuous cooling flow in the second manifold when all of the one or more secondary nozzles are closed.

  • Patent number: 8393156
    Abstract: A variable performance valve for use in a fuel nozzle is presented. The valve includes a spring, an inner spool having a port, an outer sleeve, and an orifice, which in a fuel nozzle application may be a calibration orifice. In a low flow condition, the inlet to downstream pressure is the spring force divided by the area on which the pressure acts. At low flow the orifice does not cause any appreciable pressure drop. As the flow increases, a pressure drop develops across the orifice. Since the pressure drop across the valve cannot be greater than the spring force divided by valve area, the valve is forced to open to compensate. As flow is increased, the valve will stroke completely open and the pressure drop at the port becomes negligible and the pressure drop across the orifice is nearly 100% of the pressure drop across the valve.
