Abstract: Apparatus and associated methods relate to equalizing wearing of a plurality of electrical power generators of an aircraft. Such equalization is achieved by logging operating conditions of at least a powered subset of the electrical power generators and then comparing of the logged operating conditions of each of the plurality of electrical power generators. Based on the comparison of the logged operating conditions, one of the plurality of electrical power generators for use the aircraft is recommended. A signal indicative of the recommended one of the electrical power generators determined is then generated.

Abstract: In at least one aspect of this disclosure, a shut off valve for an ecology fuel return system can include an inlet for receiving a fluid, an outlet for effusing the fluid, and a valve member configured to move between an open position such that the valve member allows fluid to effuse from the outlet and a closed position such that the valve member prevents fluid from effusing from the outlet. The valve member can include a pressure deflector configured to prevent fluid flow from biasing the valve member toward the closed position.

Abstract: An integrated flywheel energy storage device includes an inner stator having an interior support component and multiple stator cores connected to the interior support component, each with an associated stator coil arranged in multiple electrical phases. An outer rotor housing supports multiple active rotor poles which each face inward toward the stator cores, the active rotor poles being permanent magnets, copper relining, an induction squirrel cage, or variable reluctance poles. A vacuum containment housing surrounds the outer rotor housing. The outer rotor housing has a rotational moment of inertia that stores kinetic energy as a kinetic battery, allowing the device to deliver multi-phase electrical power when required. High power density is achieved by integrating the flywheel into the outer rotor housing. The device additionally functions as a gyroscope for stabilizing an exterior structure, or as a gyroscopic reference for navigational purposes when supported on a gimballed platform.

Abstract: 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.

Abstract: A fluid flow arrangement includes a manifold defining a fluid passage. A pressure sensor system is in fluid communication with the fluid passage. The pressure sensor system has a first sensor arranged along a first sense line and a second sensor arranged along a second sense line. The first and second sense lines are in fluid communication with the fluid passage. The first sense line has a first resonant frequency and the second sense line has a second resonant frequency. The second resonant frequency is different than the first resonant frequency.

Abstract: A jam-tolerant electromechanical linear actuator having a contra-rotating axial flux permanent magnet (PM) motor having a first and second rotor shafts in a motor housing. The actuator also includes a first speed reduction mechanism operably coupled to the first rotor shaft and a second speed reduction mechanism operably coupled to the second rotor shaft; a first output shaft operably coupled to a output of the first speed reduction mechanism and a second output shaft operably coupled to an output of the second speed reduction mechanism. The actuator also includes a housing enclosing the PM motor, first speed reduction mechanism and second speed reduction mechanism and a slide mechanism operably coupled to the housing. The slide mechanism permit the housing to slide when the motor housing is fixed to the housing or the motor housing to slide with respect to the housing when the housing is held fixed.

Abstract: An electro-mechanical system has a solenoid with a plunger received in a housing chamber. A plunger portion extends outwardly of the housing. There is at least one coil, and a control for the at least one coil. The control selectively applies a first higher level current to the coil to move the plunger to an actuated position relative to the housing. The control is operable to stop the supply of first high level current to the at least one coil and allow the plunger to move to an un-actuated position. The control is operable to supply a partial power current to the at least one coil when in said un-actuated position to resist movement of the plunger. A method is also disclosed.

Abstract: A heat exchanger is disclosed including an array of interlaced conduits. The conduit array includes a first plurality of conduits connected to a first inlet header at one end of the first plurality of conduits and to a first outlet header at an opposite end of the first plurality of conduits. This first plurality of conduits provides a first fluid flow path from the first inlet header through the first plurality of conduits to the first outlet header. The conduit array also includes a second plurality of conduits crossing and interlaced with the first plurality of conduits. First and second fluid flow paths are provided through the first and second pluralities of conduits, and a third fluid flow path is through open spaces between the crossed interlaced first and second pluralities of conduits.

Abstract: An ecology system includes an ecology tank, a check valve, a shutoff valve, and an ejector pump. The check valve is fluidly connected to the ecology tank and is configured to allow flow from the ecology tank. The shutoff valve is fluidly connected to the check valve, and the ejector pump is fluidly connected to the shutoff valve. The ejector pump is configured to draw fuel from the ecology tank when the shutoff valve is in an open configuration.
