摘要： A metering pump incorporates a method of relating inner loop current to a pump output pressure. Pump/motor speed, which correlates to current, is measured and controlled by a system controller. System temperature is also measured by the system controller. The controller monitors the measured system temperature and provides for compensation for system losses, including inductive-resistive (IR) losses, and for density and viscosity shifts, within a pre-determined allowable system temperature operating range. An initial system calibration is conducted using a “shut-off” test, where the metering pump is run at a very slow known speed while the system is shut-off. After initial start-up, a health-monitoring feature continues to monitor the current as an indicator of pump performance and continuously adjusts a motor speed to maintain a desired level of pump performance. This provides the system with the ability to compensate for performance losses, including performance losses due to variations in operating conditions, and to compensate for pump wear.

摘要： 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.

摘要： Oil system components for a turbine engine are used to provide a vacuum system for a fuel stabilization unit (FSU). A vacuum system pulls oxygen and other contaminants from fuel into a vacuum chamber within the FSU. The vacuum system pumps the discharge through a vacuum outlet in the FSU toward a vacuum pump. Due to the quality of vacuum required, a two-stage vacuum pump is used. A first stage vacuum pump is an oil system scavenge pump for the turbine engine and the second stage vacuum is provided by a second stage vacuum pump. The discharge flows from the vacuum chamber through to the second stage vacuum pump and is then added to the oil supply. The oil and discharge mixture is sent through an oil system de-oiler and a de-aerator to clean the oil supply prior to pumping the oil back through the oil system.

摘要： A microwave position sensing system includes a plurality of target components that each move between multiple positions. A microwave generator produces a microwave frequency signal. A divider receives the microwave frequency signal and splits the microwave frequency signal into a plurality of position sensing signals. The position sensing signals are respectively sent to the plurality of target components to determine a position of each of the target components. Each position sensing signal may also be calibrated. In one example, first and second frequencies are transmitted through a common wave guide. The first frequency is reflected prior to reaching the target component to produce a calibration signal. The second signal, which is used to detect the position of the target component, is calibrated using the first frequency.

摘要： A fuel system includes first and second drive assemblies that are independently drivable relative to one another. The second drive assembly has a speed that is selectively controlled based upon a desired fuel flow. A non-positive displacement pump is driven by the first drive assembly. The non-positive displacement pump provides a desired fuel pressure for the fuel system. A positive displacement pump is driven by the second drive assembly. The positive displacement pump meters a desired volume in response to the speed of the second drive assembly in a first rotational direction. The fuel flows from the pumps and passes through a bypass valve that acts as a minimum pressure shut-off valve. During shut-down of the first drive assembly, the bypass valve is opened by a solenoid and the rotational direction of the second drive assembly is reversed to a second rotational direction to evacuate fuel from the system with the positive displacement pump and return the fuel to the fuel tank.

摘要： 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.

摘要： An electric engine starting system includes a permanent magnet motor that is used to start the engine and then to generate power for powering a load while the engine is running. A disclosed system includes a first phase controlled rectifier in series with a power converter and a second phase controlled rectifier. During an engine starting operation, the first phase controlled rectifier is switched to couple the permanent magnet motor to a power source for starting the engine. Once the engine is running, the first phase controlled rectifier is switched off and the second phase controlled rectifier is switched on. The second phase control rectifier converts variable AC power from the motor into DC power. The power converter converts the DC power into an appropriate power for driving the load. One disclosed example includes a filter between the power converter and the load to ensure that the load receives a selected quality of power.
