Abstract: An integrated skid system integrates the functions of multiple skids into a single skid to reduce the skid footprint and the complexity of the overall system. A multi-motor controller monitors the devices on the integrated skid to maintain proper temperature, pressure and current draw in the devices. Base on this information, the multi-motor controller can make decisions on faults and fault accommodation and communicate with a main controller regarding the operating states of the skid devices via a single serial or Ethernet-type connection.

Abstract: An electric motor has at least one component that is submerged in a cooling fluid held in a fluid-filled cavity. The stator, rotor, and rotor shaft bearings are all possible components that may be submerged. The cooling fluid floods the stator, rotor, and/or bearings to cool the components. The fluid may have a high electrical resistance to isolate the motor components from any contact with flammable gasses as well as prevent arcs or sparks. The cavity holding the fluid also ensures continuous lubrication by preventing fluid from leaking or evaporating out of the motor.

Abstract: A portable interconnection system has a housing having and a plurality of communications ports adapted for connection to a plurality of audio communication networks; electronics substantially enclosed by the housing; the electronics including at least interconnection electronics operative to selectively establish a plurality of independent connection sets, each connection set interconnecting at least a plurality of the communications ports for communications between a plurality of audio communication units operating in at least two different and incompatible ones of the audio communication networks; a user interface connected to the interconnection electronics and operative to control the interconnection electronics; wherein a combined weight of the housing and the electronics is not more than fifteen pounds. A display may show an interconnection status of the plurality of audio communication units for a plurality of the independent connection sets simultaneously.

Abstract: A fluid scavenging system is provided for a lubrication system including a gas turbine engine having bearing compartments. A valve includes a housing with an outlet and a plurality of fluid inlets respectively in fluid communication with the bearing compartments. The valve includes a rotationally driven member arranged within the housing with the member having a plurality of ports arranged thereon each defining an arcuate slot. Each of the ports are selectively in fluid communication with one of the fluid inlets through the arcuate slot during rotation of the member for selectively permitting fluid flow between the opening of one of the fluid inlets through one of the corresponding ports in the member. A fluid pump is fluidly connected to the outlet for drawing fluid from each of the plurality of fluid compartments during fluid rotation of the member.

Abstract: The present invention provides a fuel system for an engine including a water supply source for providing water and a fuel supply source for providing fuel. A centrifugal pump is fluidly connected to the water and fuel supply sources, respectively at water and fuel inputs. The pump receives the water and the fuel from the inputs and produces a homogeneous mixture without using other pumps or mixing devices. A metering device is arranged between the pump and one of the supply sources, preferably the water supply source, to produce the desired ratio of water and fuel. The speed of the pump is varied to deliver the desired total volume and pressure of fuel and water to the engine through the pump output. The water metering device may be closed to deliver only fuel to the engine during special conditions such as engine startup and rapid load dumps. Operation of the system is simplified because only one pump and metering device is used.
