Abstract: A power system is disclosed that includes a chassis configured to house a first board, a second board, and a third board, in which the boards are electrically coupled to one another. The first board is configured to receive power and to output power at a first voltage and a second voltage. The second board is configured to receive power from the first board or at least one internal battery electrically coupled to the second board and to output power using at least two voltages. The third board is configured to receive power from the second board and to output power at two voltages. The boards include one or more converters configured to convert power. The one or more converters are thermally interfaced with one or more portions of the chassis so as to conduct heat into a respective portion of the chassis.

Abstract: The present invention relates to a blade folding apparatus that may incorporate an overhead blade lifting system that reduces binding loads on blade pins induced by blade weight and pitch, and a folding mechanism that removes the necessity of personnel with external guide-poles to rotate main rotor blades. The apparatus may include flap locks, an overhead lifting system support structure attached to the flap locks, and two blade support beams to create and support a lifting point near each blade' s longitudinal and lateral center of gravity. The blade support beams may be fitted with an articulation mechanism that lifts and/or lowers the overhead lifting structure. The apparatus facilitates rapid folding of the main rotor blades, and, when used with blade clamping mechanisms, is capable of aiding in the removal and/or the re-installation of the main rotor blades without external lifting mechanisms.
