Patent number: 9475574Abstract: A system is provided for dissipating heat in an onboard non-engine powered aircraft wheel drive assembly with drive means that power one or more aircraft wheels to drive the aircraft autonomously on the ground without directly using the aircraft engines. The heat dissipation system is integral with a wheel drive assembly mounted substantially completely within a nose or main landing gear wheel. A reservoir mounted outboard or inboard of the wheel drive assembly increases thermal distribution mass and fluidically communicates with wheel drive assembly components to automatically circulate heat transfer fluid between the wheel drive assembly and the reservoir when the operating temperature exceeds a predetermined maximum temperature during aircraft ground travel. The heat dissipating system can be retrofitted in an existing aircraft to improve thermal distribution and prolong wheel drive assembly and drive means operation and useful life.Type: GrantFiled: September 14, 2012Date of Patent: October 25, 2016Assignee: Borealis Technical LimitedInventors: Jonathan Sidney Edelson, Rodney T.

Patent number: 9404834Abstract: A wheel testing system and method are provided that simulates realistically conditions likely to be encountered during operation of vehicle wheels, especially powered drive wheels and wheel-connected structures. The system may include an integral support frame designed to adjustably mount wheels or wheel-connected structures to be tested, a load motor drivingly connected to an inertial load, and an adjustable mounting sled configured to adjustably mount a test wheel or a wheel-connected structure with an hydraulic system actuatable to adjust the location of the test wheel relative to the inertial load to vary or fix the load on the test wheel desired. Speed of the test wheel can be varied or fixed by controlling the speed of the load motor. System measurement and data collection electronics measure a range of selected wheel parameters and gather data for transmission to a processor or non-transitory storage medium for processing and evaluation.Type: GrantFiled: March 28, 2013Date of Patent: August 2, 2016Assignee: Borealis Technical LimitedInventors: Jonathan Sidney Edelson, Scott Perkins, Robert M.

Patent number: 9302541Abstract: A sprag clutch assembly for an aircraft drive wheel drive system capable of moving an aircraft autonomously on the ground in both forward and reverse directions is provided. The clutch is mounted within an aircraft drive wheel to be operatively engaged to control drive means braking torque when the aircraft is driven in a forward or reverse direction. The clutch assembly includes a plurality of pivoted sprag elements activatable to transmit torque and configured so that ratcheting occurs only when the aircraft drive wheel is driven in a forward direction and a braking torque is applied when the aircraft drive wheel is driven in reverse when the relative speed of the drive system is slower than the drive wheel speed, thereby permitting the drive system drive motor to function as a brake when the clutch assembly is engaged and the aircraft is reversing.Type: GrantFiled: January 17, 2014Date of Patent: April 5, 2016Assignee: Borealis Technical LimitedInventor: Jonathan Sidney Edelson

Publication number: 20160052624Abstract: A method is provided for restoring mobility to an aircraft equipped with at least one self-propelled drive wheel powered by a driver when the aircraft has been rendered immobile as a result of one or more wheel tires adhering to and becoming stuck to tarmac or another ground surface. The method uses forces generated by the cooperative action of the wheel driver, the aircraft steering, and the aircraft braking system to release adherent tires of each set of main wheels and/or nose gear wheels by applying differential force to one set of wheels at a time to release any adherent tires so that the aircraft is able to move on the ground surface and travel in a desired direction at a desired speed.Type: ApplicationFiled: February 3, 2012Publication date: February 25, 2016Inventors: Jonathan Sidney Edelson, Isaiah W Cox, Neal Gilleran, Scott Perkins

Patent number: 9216819Abstract: A wheel design is provided for an aircraft landing gear wheel that is configured to maximize the space available within a landing gear wheel well to support a motor driver assembly that drives the aircraft wheel when the aircraft is on the ground. The wheel includes inboard and outboard support walls that are spaced apart a selected distance along the wheel axle so that the motor driver assembly components are substantially completely contained within the wheel space defined by the support walls. The preferred motor driver assembly includes an electric motor and a gear and clutch assembly operatively connected to the wheel to drive the wheel and move the aircraft on the ground. The wheel and motor driver assembly described herein may be retrofitted in an existing aircraft wheel without changing existing landing gear components, including tires, piston, and axle.Type: GrantFiled: March 29, 2011Date of Patent: December 22, 2015Assignee: Borealis Technical LimitedInventors: Neal Gilleran, Robert M.

Patent number: 9193449Abstract: A method is provided for automatically or manually optimizing independent ground travel operation in an aircraft equipped with one or more self-propelled nose or main wheels powered by a driver means, wherein selected operating parameters indicative of optimized ground travel are monitored by sensors or detectors to provide data and information relating to the selected parameters during operation of the ground travel system. Selected operating parameters can include, for example, speed, direction of travel, torque, component thermal data, aircraft location data, and operator inputs, commands, and feedback, as well as other operational data or information. Data is collected, recorded, and analyzed to enable changes to be made to the ground travel system components in real time automatically by intelligent software or manually by a system operator or at a later time to ensure optimum operation of the system.Type: GrantFiled: August 22, 2012Date of Patent: November 24, 2015Assignee: Borealis Technical LimitedInventors: Isaiah W.

Patent number: 9010959Abstract: A system and method for generating artificial light for interior or exterior illumination are provided to illuminate interior and exterior underground, underwater, ground level, and above ground structures and spaces by employing various combinations of solar photovoltaic-generated power and conventional power to directly power LED or other light sources to provide interior or exterior illumination of a desired optimal intensity. One embodiment of this system provides a virtual skylight that illuminates interior structures and spaces with the benefits of illumination provided by a conventional skylight but without the disadvantages. A direct connection between a solar photovoltaic cell and the LED or other light-producing source eliminates complex and costly circuitry in both interior and exterior applications. The system is configured to provide, alternatively, solar PV power and/or conventional power as required to maintain artificial illumination at a desired optimum threshold intensify.Type: GrantFiled: August 8, 2012Date of Patent: April 21, 2015Assignee: Borealis Technical LimitedInventors: Jonathan Sidney Edelson, Rodney T.

Patent number: 8299673Abstract: A high phase order induction machine wound and permitted by coil symmetry to operate at fewer than the magnetically optimal number of poles is constrained by symmetry to be a two pole machine and be capable of operating on odd harmonics only, but with back-iron, end rings, and rotor core optimized for 10 pole operation, might be used normally in ‘5th harmonic’ mode, with ‘7th harmonic’ utilized to engage the ‘mesh effect’. Such a machine thus appears to be operating in the ‘1.4 harmonic’. A high phase order induction machine driven by a second harmonic drive, in which a symmetry imposed by full span windings is broken. This may be most simply accomplished through the use of short pitch windings. Other possible approaches include using non-wound slot drive, and using toroidal windings which localize coils to individual slots.Type: GrantFiled: January 9, 2008Date of Patent: October 30, 2012Assignee: Borealis Technical LimitedInventor: Jonathan Sidney Edelson
