  • Publication number: 20190023412
    Abstract: An aircraft may include at least one secondary power system requiring secondary power, at least two main engines, and at least three non-propulsive utility power (NPUP) generation systems. The NPUP generation systems may each be configured to provide full-time secondary power during operation of the aircraft. The NPUP generation systems may be configured to provide at least a portion of the secondary power required by the secondary power system.
    Type: Application
    Filed: October 10, 2017
    Publication date: January 24, 2019
    Inventors: David S. Krug, Kamiar J. Karimi, Thomas F. Currier, Andrew J. Bayliss, George M. Roe, Mark E. Liffring, Mark W. Lesyna, Christopher M. Severns, Andrew Johnson

  • Patent number: 9561760
    Abstract: A modular truss assembly configured to be placed in small or narrow spaces such as within the floor, sidewall, or crown of a vehicle for mechanically and electrically mounting system components of a modular equipment center (MEC). A plurality of MECs is spatially distributed throughout the vehicle to service equipment loads. The modular truss assembly provides different voltage levels for powering the system components of the MEC and for powering the equipment loads. In one or more configurations, all or part of the modular truss assembly can be removed from the vehicle for repair or replacement.

  • Patent number: 9413162
    Abstract: Distributed electronic protections and control architecture enabling simultaneous fault clearance without conflicting fault isolation logic. A plurality of modular equipment centers (MECs) is spatially distributed throughout a vehicle to service equipment loads with power and data. In one embodiment, protective functions are embedded on integrated protection chipsets (IPCs) within the distributed architecture of the vehicle. The IPCs implement a plurality of protective functions where coordinated or independent fault assessments are performed.

  • Patent number: 9183983
    Abstract: A modular truss assembly for mechanically and electrically mounting system components of a modular equipment center (MEC). A plurality of MECs is spatially distributed throughout the vehicle to service equipment loads. The modular truss assembly provides different voltage levels for powering the system components of the MEC and for powering the equipment loads. In one or more configurations, a MEC incorporate inductive power coupling for powering a line replaceable unit (LRU) in proximity to the modular truss assembly without exposed electrical connections and such that the MEC may forgo power conversion equipment. In one or more configurations, a sensor is embedded in one or more transfer layers of the truss for measuring a power trace embedded in the modular truss assembly.
