摘要： A control surface disconnect detection system includes a mechanical disconnect detection device that includes: a first contact element; a second contact element; and a mechanical fuse that includes a conduction path. In a normal operational state the conduction path creates an electrical pathway between the first contact element and second contact element and when in a control surface disconnected state the conduction path does not create an electrical pathway between the first contact element and the second contact element. The system also includes a radio frequency identification (RFID) tag connected to the first contact element and the second contact element such that when the mechanical disconnect detection device is in the normal operation state the RFID tag does not transmit information, and when the mechanical disconnect detection device is in the control surface disconnected state the RFID tag does transmit information.

摘要： A controller for an inline valve includes a manifold seating a set screw and has a reference fluid port, a control fluid port, and an actuator fluid port. A selector is movable within the manifold between a first position and a second position, the reference fluid port in fluid communication with the actuator fluid port in the first position, the control fluid port in fluid communication with the actuator fluid port in the second position. A biasing member is arranged between the selector and the set screw and urges the selector towards the first position. The set screw extends through an exterior of the manifold for adjustment of differential in pressures at the reference fluid port and the control fluid port responsive to which the selector moves between the first position and the second position. Inline valves and methods of controlling fluid flow through inline valves are also described.

摘要： A ram air fan and fan bypass shutoff check valve assembly includes a ram air fan configured to draw an airflow through a fan inlet, and a ram fan bypass duct positioned downstream of the ram air fan. The ram fan bypass duct includes a valve assembly configured to selectably direct the airflow through the ram air fan when the valve assembly is in an open position, and direct the airflow through a bypass duct thereby bypassing the ram air fan when the valve assembly is in a closed position.

摘要： An electric motor control system, including an electric motor having a first winding set including first and second parallel windings, the first and second windings operable to each current based on the combined phase current, and a differential current sensor operably coupled to the first winding and the second winding. The differential current sensor measuring a differential current flowing through the first winding and the second winding and operable to transmit a signal indicative of the differential current based on the measuring. The system also includes a motor controller connected to the electric motor, the motor controller operable to direct the combined phase current through the phase lead, receive the differential current signal, determine if the differential current flowing through the winding set exceeds a selected threshold, and identify a health status of the motor winding set as degraded if the differential current exceeds the selected threshold.

摘要： A tank assembly is provided and includes a housing which has a housing volume and which is chargeable with a volume of a first fluid, a bladder disposed within the housing and chargeable with a second fluid such that the bladder has a minimal volume in an uncharged state and a flow system. The flow system includes a portion thereof which is coupled to the bladder and which has a second volume within the housing. The flow system is configured to at least charge the bladder with a volume of the second fluid which is equal to or less than a difference between the housing volume less a sum of the minimal volume and the second volume and the volume of the first fluid.
