摘要： A method of determining density of a fluid within a system includes actuating a piston of a hydraulic cylinder at a target velocity. Additionally, the method includes determining differential pressure and volumetric flow rate of the fluid flowing through an orifice under actuation of the piston. The density of the fluid is determined based on the first differential pressure and the volumetric flow rate of the fluid, which is used by the system to regulate a mass flow rate of fluid within the system.

摘要： A filter assembly for a fluid flow system includes a filter housing, a housing inlet to allow the fluid flow into the filter housing and a housing outlet to allow the fluid flow to exit the filter housing. A filter element is located in the filter housing to collect contaminants from the fluid flow. A pressure sensor is located to measure a pressure drop across the filter element. The pressure sensor includes at least one sense line extending into an interior volume of the filter housing. A method of monitoring a filter assembly for a fluid flow system includes positioning a pressure sensor at a filter assembly, extending at least one sense line from the pressure sensor into an internal volume of a filter housing of the filter assembly, and measuring a pressure drop across a filter element of the filter assembly via the pressure sensor.

摘要： A tip clearance measurement system (TCMS) includes a probe and sensing circuitry. The probe directs microwave signals toward a turbine blade and receives microwave signals reflected by the turbine blade. The sensing circuitry includes a switch having a first state in which a main frequency is provided at an output of the switch and a second state in which a reference frequency is provided at an output of the switch. The sensing circuitry further includes a first conditioning circuit that receives a frequency provided at the output of the switch and provides a conditioned frequency to the probe and a second conditioning circuit that receives both the conditioned frequency provided by the first conditioning circuit and a reflected frequency received by the probe, and provides a conditioned output based on the conditioned frequency and reflected frequency.

摘要： A system includes a metering module that receives fluid through a fluid inlet. The metering module includes a rotating component driven by the fluid, an electric machine, and a controller. The fluid is received from the fluid inlet at an inlet flow rate, and the rotating component provides the fluid to an outlet of the rotating component at an outlet pressure. The electric machine is configured to generate electrical power in response to rotation of the rotating component. The controller is powered by the electrical power generated by the electric machine, and controls a rotational speed of the rotating component to control the outlet pressure.

摘要： A fluid system has a fluid actuator that receives a fluid to cause movement of a component. A valve selectively controls the flow of fluid to the fluid actuator. A motor for the valve is provided with an electric voltage or current. A control applies a pulse width modulation variation to the supplied voltage or current. The control is operable to vary the pulse width modulation of the voltage or the current based upon conditions of the system. A mechanical system and a method are also disclosed.

摘要： An in-line shutoff valve includes a valve body with an inlet chamber, an outlet chamber, and a poppet seat disposed between the inlet and outlet chambers. A poppet is movably disposed within the valve body and has an open and closed position. The poppet seats against the poppet seat in the closed position, fluidly separating the inlet chamber from the outlet chamber. The poppet is unseated from the poppet seat in the open position, fluidly coupling the inlet and outlet chambers. A manifold with a servo port and a vent port is disposed within the valve body between the inlet and outlet chambers, the vent port being in fluid communication with the servo port to cool valve internal structures when the poppet is in the closed position.

摘要： An electromagnetic solenoid actuator comprises a ferromagnetic core and a ferromagnetic plunger. The ferromagnetic core supports a plurality of windings, and is oriented along an axis. The ferromagnetic plunger is aligned axially with the ferromagnetic core, and is translatable along the axis to vary a width of an air gap separating the ferromagnetic plunger from the ferromagnetic core. The ferromagnetic plunger and the ferromagnetic core overlap axially at a flux bypass that provides an alternative flux path that diverts increasing flux away from the air gap as the width of air gap decreases.

摘要： Distributed fuel control system and methods are disclosed. A distributed fuel control system may comprise a controller, a fuel delivery system, and fuel delivery system sensors and combustion sensors. The controller may output a control signal in response to at least one of the fuel delivery system sensor or the combustion sensors. In response, the fuel flow to individual multiplex fuel delivery unit may be controlled according to various methods. One such method includes determining a desired fuel pressure differential, directing a torque motor to set a pressure regulator to a position corresponding to the desired fuel pressure differential, determining a sensed fuel pressure differential, and adjusting the torque motor in response to a difference between the sensed fuel pressure differential and the desired fuel pressure differential.
