20120232728 | Vehicle Electrical Power Management and Distribution - Vehicles, systems, and methods are disclosed for providing and directing first power, such as vehicle generator power, and alternate sources of power. In a particular embodiment, a vehicle includes a power distribution grid that includes a plurality of power sources and a plurality of distributions buses configured to distribute power from the plurality of power sources. The plurality of power sources include an engine-driven power source is configured to provide first power where the first power has first power characteristics. The plurality of power sources also includes a plurality of engine-independent power sources including a first alternate power source configured to provide first alternate power. The first alternate power has first alternate power characteristics that are different than the first power characteristics. The plurality of engine-independent power sources also includes a second alternate power source configured to provide second alternate power. The second alternate power has second alternate power characteristics that are different from the first power characteristics and different from the first alternate power characteristics. The vehicle also includes a global controller that sends control signals to control generation of power by the engine-driven power source, the first alternate power source and the second alternate power source via the plurality of distribution buses responsive to power demand of the power distribution grid. | 09-13-2012 |
20150102659 | Modular Equipment Center Lightning Threat Reduction Architecture - A composite vehicle architecture without a current return network for reducing lightning threats. A plurality of modular equipment centers (MECs) are spatially distributed throughout the vehicle. Equipment loads within the vehicle are each serviced by the nearest MEC. Twisted and shielded electrical conductor pairs provide secondary power to the equipment loads to minimize the amount of wire throughout the aircraft as well as the return currents on the aircraft. | 04-16-2015 |
20150102660 | Modular Equipment Center Distributed Equipment Packaging Truss - 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. | 04-16-2015 |
20150102661 | Modular Equipment Center Distributed Primary Power Architecture - A plurality of modular equipment centers (MECs) spatially distributed throughout a vehicle servicing equipment loads. Each MEC independently provides localized power and communication to service the equipment loads and each equipment load is serviced by the nearest MEC. In at least one embodiment, only primary power is distributed across section breaks of the vehicle to minimize the number of connections between section breaks, reduce overall vehicle weight, and to increase vehicle build rate. | 04-16-2015 |
20150102662 | Modular Equipment Center Zonal Standalone Power System Control Architecture - A plurality of modular equipment centers (MECs) spatially distributed throughout a vehicle servicing equipment loads. Each MEC independently provides localized power and communication to service the equipment loads. A zone of electrical loads is assigned to and serviced by the nearest MEC. Power and communication data are synchronized in that each equipment load receives power and data from the same MEC. In one embodiment, if a MEC experiences an operational inconsistency, one or more other MECs are assigned the equipment loads of the operationally inconsistent MEC. | 04-16-2015 |
20150103457 | Modular Equipment Center Solid State Primary Power Switching Network - A solid state primary power switching network for modular equipment centers (MECs) distributing primary power throughout a vehicle. The solid state primary power switching network includes multiple primary power switch network devices (PPSNDs) of a MEC for controlling and distributing primary power to other MECs spatially distribute throughout a vehicle. In one or more configurations, the PPSNDs have a universal structure in that each includes a common power input source and a plurality of common power outputs. In one or more configurations, primary power sources to the vehicle are switched without a perceivably visible break in power. | 04-16-2015 |
20150103458 | Modular Equipment Center Integrated Truss Sensors - 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. | 04-16-2015 |
20150151847 | NON-PROPULSIVE UTILITY POWER (NPUP) GENERATION SYSTEM FOR PROVIDING SECONDARY POWER IN AN AIRCRAFT - 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. | 06-04-2015 |
