Abstract: A hybrid electric aircraft powerplant arrangement can include a first wing pair of powerplants for a first wing of an aircraft, the first wing pair comprising a first electric powerplant configured to drive a first air mover and a first heat engine powerplant configured to drive a second air mover separate from the first air mover. The arrangement can include a second wing pair of powerplants for a second wing of the aircraft, the second wing pair comprising a second electric powerplant configured to drive a third air mover separate from the first and second air movers, and a second heat engine powerplant configured to drive a fourth air mover separate from the first, second, and third air movers.

Abstract: An integrated turbo-compressor includes a compressor with a compressor outlet, a turbine with a turbine inlet, the turbine operatively connected to the compressor by an interconnect shaft, and a compounding drive. The compounding drive is connected to the turbine and has a variable gear ratio and an output member, the variable gear ratio coupling the turbine to the output member to compound output of an internal combustion engine using energy recovered from an exhaust flow received from the internal combustion engine and in excess of energy required to compress combustion air provided to the internal combustion engine. Internal combustion engines, aircraft, and methods of compounding output of internal combustion engines are also described.

Abstract: A hybrid drive system can include a shaft, an electrical machine comprising a rotor and a stator, and a mechanical disconnect system connecting the rotor to the shaft. The mechanical disconnect system is configured to mechanically connect the rotor to the shaft in a first state and to mechanically disconnect the rotor from the shaft in a second state such that rotor does not drive the shaft or such that the rotor is not driven by the shaft. The rotor can be a permanent magnet rotor, for example.

Abstract: An aircraft propulsion system includes a hybrid-electric power plant for delivering power to an air mover for propelling an aircraft. The hybrid-electric power plant includes a heat engine operatively connected to a first air mover, and an electric motor operatively connected to a second air mover. The second air mover is positioned on a wing of the aircraft outboard from the heat engine. A method for reducing trailing vortices includes powering a first air mover of an aircraft with a heat engine during a take-off stage, a climb stage, a cruise-stage and/or a descent stage. The method includes powering a second air mover of the aircraft with an electrical motor during the take-off stage and/or the climb stage. The method includes freewheeling the second air mover during the cruise stage and/or the descent stage to generate mechanical energy and reduce wing tip vortices.

Abstract: An electrical system for a vehicle can include a power supply and one or more electric motors comprising one or more electric motor controllers operatively connected to the power supply to selectively receive electrical energy from the power supply to provide electrical energy to one or more electric motors. The one or more electric motor controller can have one or more switches and operatively connected between the power supply and the one or more electric motors. The electric motor controller can be configured to modify the electrical path between the power supply and the electric motor using the one or more switches to cause at least one of a shunt to the power supply or a shunt to the electrical motor drives in an overvoltage state. The system can also include an electrical load operatively connected to the power supply. The electrical motor controller can be configured to provide overvoltage protection to the electrical load in the overvoltage state without secondary overvoltage protection circuitry between the power supply and the electrical load.

Abstract: A dual-output generator includes a first generator with a rotor, a second generator with a rotor, and first and second power converters. The rotor of the first generator is coupled to the rotor of the second generator for common rotation with the rotor of the first generator. The first power converter connects electrically to the first generator for converting rotation of the first generator rotor into direct current power. The second power converter connects electrically to the second generator for converting rotation of the second generator rotor into constant frequency alternating current power.
