Abstract: A power distribution system is disclosed for conducting electrical power through a combination of hollow tube conductors and flexible cabling. Each hollow tube conductor includes an end formed into flat pads. The flexible cabling comprises litz wire, and includes ends crimped to integral lugs. An end of the flexible cabling is coupled to an end of the hollow tube conductor. The other end of the flexible cabling is coupled to an electric device. The other end of the hollow tube conductor is coupled to another flexible cable, which is in turn coupled to another electric device. By connecting the hollow tube conductors, flexible cabling, and electrical devices in this way, an electrically conductive pathway may be established between the electrical devices. The power distribution system conducts alternating current (AC) power, and addresses the skin effect phenomenon that occurs when conducting AC power. The power distribution system can be utilized in the highly-constrained environment of electric aircraft, where weight and space is at a premium.

Abstract: A hybrid propulsion aircraft is described having a distributed electric propulsion system. The distributed electric propulsion system includes a turbo shaft engine that drives one or more generators through a gearbox. The generator provides AC power to a plurality of ducted fans (each being driven by an electric motor). The ducted fans may be integrated with the hybrid propulsion aircraft's wings. The wings can be pivotally attached to the fuselage, thereby allowing for vertical take-off and landing. The design of the hybrid propulsion aircraft mitigates undesirable transient behavior traditionally encountered during a transition from vertical flight to horizontal flight. Moreover, the hybrid propulsion aircraft offers a fast, constant-altitude transition, without requiring a climb or dive to transition. It also offers increased efficiency in both hover and forward flight versus other VTOL aircraft and a higher forward max speed than traditional rotorcraft.

Abstract: A tooling system for fabricating a composite structure comprising a printed thermoplastic material tooling component having a non-tooling surface and a tooling surface, wherein the tooling surface defines a predetermined shape for the composite structure. The tooling system may further comprise a printed thermoplastic material tooling base structure having a plurality of non-tooling surfaces to support the printed thermoplastic material tooling component during layup or cure. The printed thermoplastic material tooling base structure may employ a support structure, such as a honeycomb support structure or a filler material.
