An example system includes one or more battery modules, a battery module of the one or more battery modules comprising: a cylindrical pressure vessel; a cooling channel extending axially through the cylindrical pressure vessel; and one or more battery packs within the cylindrical pressure vessel, a battery pack of the one or more battery packs comprising a plurality of battery cells radially distributed about the cooling channel.

Circular configuration of battery cells for aircraft

An example system includes a first plurality of nacelles located on a first side of an aircraft, wherein each nacelle of the first plurality of nacelles includes an electric motor coupled to a propulsor, wherein an outboard nacelle of the first plurality of nacelles includes an electrical energy storage system (ESS) coupled to a first electrical bus; and a second plurality of nacelles located on a second side of the aircraft, wherein each nacelle of the second plurality of nacelles includes an electric motor coupled to a propulsor, wherein an outboard nacelle of the second plurality of nacelles includes an ESS coupled to a second electrical bus.

Aircraft with electrical energy storage in nacelles

A gas turbine engine includes first and second electrical machines coupled to the gas turbine engine, each of the first and second electrical machines electrically coupled to both a primary electrical bus and a secondary electrical bus. The gas turbine includes a first controller configured to control operation of the gas turbine engine, and a second controller coupled to the first controller, the second controller configured to respond to control inputs from the first controller and control an electrical output of the first and second electrical machines to the primary and secondary electrical busses. A converter controller is coupled to an energy storage system, the second controller, the primary electrical bus, and the secondary electrical bus.

Gas turbine engine and electrical system

The present disclosure provides an apparatus with a prime mover coupled to a generator that is directly electrically coupled to an electric motor. A propeller or fan may be coupled to and driven by the electric motor. A bi-directional power converter may be coupled to the generator and further coupled to an energy storage device. The energy storage device may be selectively coupled to the electric motor. Methods of using the apparatus are also provided.

Electric direct drive for aircraft propulsion and lift

A gas turbine engine includes an electrical system that includes a controller coupled to a first inverter/converter controller, a second inverter/converter controller, and a converter/controller that is coupled to an energy storage device. The system is configured to provide electrical power to a first electrical bus and a second electrical bus, from first and second electrical machines, under the direction of the controller. The converter controller is configured to control the amount of electrical power supplied to the first electrical bus and the second electrical bus from the energy storage system. The amount of electrical power received from the first electrical bus and the second electrical bus, and energy supplied to the energy storage system are under the direction of the controller.

One embodiment of the present invention is a unique method of controlling the output of a synchronous electrical machine. Another embodiment is a unique method of controlling the output of a synchronous electrical machine for powering a load. Still another embodiment is a unique aircraft power generation system. Other embodiments include apparatuses, systems, devices, hardware, methods, and combinations for fluid driven actuation systems.

Systems and methods for synchronous power generation

An electrical power generation apparatus is embedded in a contra-rotating propulsion system that includes overlapping first and second shafts operatively connected for counter-rotation about a common axis. The electrical power generation apparatus includes a winding mounted to one of the shafts and a field array mounted to the other of the shafts adjacent to the winding. Relative rotation of the winding and the field array induces electrical current in the winding.
