Patent number: 11681312Abstract: Aircraft power distribution systems and methods for regulating a system voltage in aircraft power distribution systems are described. An example system includes a first generator, a first power feeder, a second power feeder, a first load, a second load, and a plurality of contactors. The first power feeder and the second power feeder are coupled in parallel between the first generator and a power panel. The first load is coupled to the first power feeder, and the second load is coupled to the second power feeder. The plurality of contactors is configurable to transfer power in a first direction from the first generator to both the first load and the second load during a first mode of operation, and configurable to transfer power in a second direction from the power panel to the first load or the second load during a second mode of operation.Type: GrantFiled: January 4, 2021Date of Patent: June 20, 2023Assignee: The Boeing CompanyInventor: Jeffrey J.

Patent number: 11465759Abstract: On an aircraft, a multi-mode power generator is operated in a variable voltage mode to power an electric Wng Ice Prevention System (eWIPS), and is operated in a fixed voltage mode to provide backup power. When atmospheric conditions are conducive to the formation of ice (and main generators are operative), the multi-mode power generator is operated in variable voltage mode to power the eWIPS with a first or second variable voltage. The first variable voltage, the value of which depends on atmospheric conditions, is for anti-ice operation. The second variable voltage, which can be the maximum output voltage, is for de-ice operation. Transitions between different variable voltage levels are not instantaneous which eliminates fatigue damage due to transients. If a main generator fails (or when atmospheric conditions are not conducive to the formation of ice), the multi-mode power generator is operated in fixed voltage mode to provide backup power.Type: GrantFiled: July 13, 2018Date of Patent: October 11, 2022Assignee: THE BOEING COMPANYInventor: Jeffrey J.

Patent number: 11034463Abstract: An auxiliary power unit (APU) control system for an aircraft is disclosed and includes an APU, an air inlet having an effective area, an air inlet door moveable to vary the effective area of the air inlet, an actuator configured to move the air inlet door into a set position, one or more processors, and a memory coupled to the one or more processors. The memory stores data comprising a database and program code that, when executed by the one or more processors, causes the APU control system to receive one or more ambient signals indicative of an air density value. The system also determines the effective area of the air inlet based on the air density value. The system is further caused to instruct the actuator to move the air inlet door into the set position.Type: GrantFiled: March 26, 2019Date of Patent: June 15, 2021Assignee: The Boeing CompanyInventor: Jeffrey J.

Patent number: 9588535Abstract: An apparatus and method for resetting a motor controller. It is determined whether a tripping of the motor controller is accompanied by an undesired condition elsewhere in a power system wherein an alternating current bus receives alternating current power from a generator, a power converter converts the alternating current power on the alternating current bus to direct current power on a direct current bus, and the direct current power on the direct current bus powers the motor controller. In response to a determination that the tripping of the motor controller is accompanied by the undesired condition, it is determined whether the undesired condition is less than a threshold for more than a time delay. The motor controller is reset in response to a determination that the undesired condition is less than the threshold for more than the time delay.Type: GrantFiled: June 23, 2014Date of Patent: March 7, 2017Assignee: THE BOEING COMPANYInventors: Eugene V.

Patent number: 8760094Abstract: An apparatus and method for protecting a power system comprising a generator providing power to an alternating current bus, a power converter for converting alternating current power on the alternating current bus to direct current power on a direct current bus, and a direct current load powered by the direct current power on the direct current bus. An undesired condition is identified at the input to the power converter from the alternating current bus. The undesired condition is caused by at least one of the power converter, the direct current bus, or the load. The power converter is disconnected from the alternating current bus in response to identifying the undesired condition for at least a time delay. The time delay is selected such that the power converter is disconnected from the alternating current bus before the alternating current bus is disconnected from the generator due to the undesired condition.Type: GrantFiled: December 9, 2011Date of Patent: June 24, 2014Assignee: The Boeing CompanyInventors: Eugene V.
