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.

Modular equipment center distributed primary power architecture

An electrical architecture for an aircraft is provided. The electrical architecture is particularly suitable for relatively small, compact, and lightweight aircraft. In one embodiment, the electrical architecture includes an electrical generator component coupled to the aircraft engine, and an air compression system coupled to the electrical generator component. The electrical generator component is configured to receive mechanical power from the engine and to generate a constant frequency AC electrical power from the engine mechanical power, and the air compression system is configured to receive the constant frequency AC power as an input and, in response thereto, produce a pressurized air output having variable characteristics (for example, a variable flow rate or a variable air pressure).
