Abstract: Systems, methods, and devices are provided for a turbine driven pump gearbox. A turbine engine may drive a primary shaft having gears. The gears may selectably engage with gears of a secondary shaft that drives a machine (e.g., pump). By changing which gears of the primary shaft engage with which gears of the secondary shaft, a gear ratio may be changed. A power takeoff device (e.g., a generator) may be connected to the primary shaft and may be operated in reverse as a motor to rotate, slow, stop, and/or reverse rotation of the primary shaft. Brakes may be associated with one or more of the primary and secondary shafts. The power takeoff device and one or more of the brakes may be controlled to shift engagement of the shafts between different positions, changing the gear ratio and/or disengaging the shafts from each other.

Abstract: A pumping system includes a pump array of multiple pump-engine assemblies. Each pump-engine assembly comprises a pump and a gas turbine engine driving the pump. A manifold is coupled to the pumps. A master controller is coupled to each of the pump-engine assemblies either directly or via one or more intermediate controllers. The master controller and any intermediate controllers are collectively programmed to respond to user input including a desired hydraulic output at the manifold by automatically calculating and applying inputs to the individual pump-engine assemblies to provide the desired hydraulic output.

Abstract: A system controller manages a gas turbine engine driving a pump directly or indirectly coupled to the engine. The controller is programmed to automatically determine and adjust inputs to the gas turbine engine in order to cause the pump to produce a user-specified hydraulic output.

Abstract: A pump system for high pressure, high volume applications is presented. The pump system includes a turbo-shaft engine having a drive shaft and a high pressure, high RPM centrifugal pump coupled to the drive shaft. In certain embodiments the pump system further includes a second low pressure, high RPM centrifugal pump coupled to the drive shaft.

Abstract: A controller for a gas turbine engine is configured to respond to one or more prescribed engine overspeed conditions. Rather than shutting the engine down, the controller substantially reduces N1 airflow and substantially concurrently activates one or more engine igniters.

Abstract: At least one controller manages a gas turbine engine driving a generator directly or indirectly coupled to the engine. The controller is programmed to automatically determine and adjust inputs to the gas turbine engine in order to cause the generator to produce a user-specified electrical output. Multiple sets of generator, engine, and controller may be used, in which case a master controller individually manages the other controllers to collectively provide the a user-specified electrical output.

Abstract: A method and apparatus is presented for communicating between a platform and multiple objects, where the objects comprise a set of parameters and an object-specific interface protocol, where at least one of the object-specific interface protocols differs from at least one other object-specific interface protocol. The method includes identifying the objects and creating multiple nonobject-specific data structures, where at least one of the nonobject-specific data structures can engage each parameter of each set of parameters. The method further includes transforming, using the plurality of nonobject-specific data structures created, the object-specific interface protocols into a single nonobject-specific interface protocol for communicating between the platform and the objects.

Abstract: A method and apparatus is presented for using multiple device specific interface protocols for communicating with a platform, where each of the devices comprises a set of parameters. For each parameter of each set of parameters a function call is established to set the parameter for each of the devices that enable the parameter. Using each function call, the plurality of object specific interface protocols is then transformed into a non-device specific interface protocol for communication with the platform.
