Jeff A. Lotterman has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • On-board inert gas generation turbocompressor systems and methods
    Patent number: 8015838
    Abstract: The present invention provides a system and method for cooling the bleed air supply in an on-board inert gas generation system. The gas generation system cools the bleed air using a turbocompressor in conjunction with heat exchangers. Exhaust from a regenerative heat exchanger providing air to the turbocompressor is ported to a ram air outlet using a flow-restriction/ejector unit.
    Type: Grant
    Filed: December 21, 2007
    Date of Patent: September 13, 2011
    Assignee: Honeywell International Inc.
    Inventors: Timothy J. Lippold, Giorgio C. Isella, Jeff A. Lotterman, Jon E. Schryver

  • Thermal and secondary flow management of electrically driven compressors
    Patent number: 7633193
    Abstract: A cooling system for an electrical motor or generator includes a first cooling loop, a second cooling loop, and a heat exchange system. The first cooling loop may extract heat from an iron stack and winding of the electrical motor or generator. The second cooling loop may extract heat from end turns of the stator winding, the rotor, and the bearings independently from and simultaneously to the first cooling loop. At least the first cooling loop may pass through the heat exchange system. A liquid coolant may circulate in the first cooling loop and a compressed gas, such as compressed air or compressed refrigerant in vapor form, may circulate in the second cooling loop. The cooling system and method for an electrical motor or generator may be suitable for, but not limited to, applications in the aircraft and aerospace industries, such as driving a cabin air compressor of an aircraft.
