Patent number: 11092175Abstract: A dual-independent hybrid actuator system includes an actuator body defining a hydraulic chamber. The actuator system includes a hydraulic piston assembly, including a hydraulic piston disposed within the hydraulic chamber and dividing the hydraulic chamber into a first hydraulic sub-chamber in fluid communication with a first hydraulic fluid passage and a second hydraulic sub-chamber in fluid communication with a second hydraulic fluid passage. The actuator system further includes a piston rod mounted to the hydraulic piston that passes through the second hydraulic sub-chamber with a distal end that projects outward from the actuator body. The actuator system further includes an electric motor mounted to the actuator body, and a threaded axle mechanically coupled to a motor shaft of the electric motor. The threaded axle passes through the first hydraulic sub-chamber and engages with a threaded port formed in the hydraulic piston assembly.Type: GrantFiled: March 23, 2020Date of Patent: August 17, 2021Assignee: THE BOEING COMPANYInventors: David E.

Patent number: 11016149Abstract: A battery management system (BMS) described herein determines the internal resistance for a cell that may have an internal short circuit. In one aspect, the BMS monitors the voltage across each of a plurality cells that are coupled in series. If the voltage across one of the cells differs from the voltages across the other cells, the BMS can flag the cell as potentially having an internal short circuit. Once flagged, the BMS can use a simulator that stores a model cell that has similar characteristics as the cells monitored by the BMS to determine the internal resistance of the flagged cell. In one aspect, the simulator changes the value of a surrogate resistor that is parallel with the model cell until the voltage across the model cell matches the voltage of the flagged cell. The value of the surrogate resistor indicates the internal resistance of the flagged cell.Type: GrantFiled: June 24, 2019Date of Patent: May 25, 2021Assignee: THE BOEING COMPANYInventors: Jimmy M.

Patent number: 10483880Abstract: A system for controlling multiple actuators that are attached to a structure for moving and positioning the structure include a magnetic flux sensor in a motor of each actuator. The magnetic flux sensor senses a magnetic flux in an associated motor and generates an electrical signal that corresponds to the magnetic flux in the associated motor. The system also includes a control unit that receives the electrical signal from the magnetic flux sensor of each actuator. The control unit is configured to generate a drive command signal to each actuator that balances a torque applied to the structure by each actuator in response to the magnetic flux sensed in the motor of each actuator.Type: GrantFiled: October 10, 2016Date of Patent: November 19, 2019Assignee: The Boeing CompanyInventors: James L.

Patent number: 10218277Abstract: Increased DC-to-AC power conversion efficiency in a scalable, flexible, resilient, cascading inverter driver topology. Plural power cells, which include a rectifier and an inverter, are arranged in a series/parallel topology. Use of plural power cells increases efficiency by reducing voltage transition losses and by increasing duty cycle. Also, the power cells output AC to an electric motor using a forward-looking controller that responds to varying power demand while maintaining motor speed at a maximum efficiency level. Power output is varied by varying the width of rectifier output pulses to the inverters while maintaining pulse voltage. Transitions between power levels are smoothed by pulse density modulation. Pulse density, determined automatically in the inverter, begins high and gradually becomes less dense so voltage changes rapidly then slowing gradually. The topology and power cell components allow faulty power cells 10 to be isolated and bypassed.Type: GrantFiled: February 22, 2016Date of Patent: February 26, 2019Assignee: The Boeing CompanyInventors: Michael A.
