Abstract: A vertical takeoff and landing aircraft includes rotors that provide vertical and horizontal thrust. During forward motion, the vertical lift system is inactive. A lift fan mechanism positions the fan blades of the aircraft in a collapsed configuration when the vertical lift system is inactive and positions the fan blades of the aircraft in a deployed configuration when the vertical lift system is active.

Abstract: A power distribution system comprises a plurality of energy storage modules coupled in series. A plurality of electrically isolated power converters are each coupled across one or more of the energy storage modules. When enabled, the power converters provide a low voltage output to an output of the power distribution system. A control system controls the power converters to provide the low voltage output. The control system selectively enables the power converters to balance states of charge of the energy storage modules.
