  • Patent number: 11303194
    Abstract: A cryogen-free partially-superconducting electric machine of the wound field synchronous type includes a room temperature semi-slotless stator, a superconducting motor rotor, a gap between the rotor and stator, a torque tube which isolates the cryogenic superconducting motor rotor from a central shaft, bearings, an acoustic cryocooler integrated within the motor rotor and torque tube, a heat exchange, a rotary transformer, a vacuum pump, a vacuum enclosure integrated with the stator, and an eddy current/thermal shield. The electric machine can act as a motor or a generator and produces a high specific power and efficiency.

  • Patent number: 11183626
    Abstract: A magnetostrictive alternator configured to convert pressure waves into electrical energy is provided. It should be appreciated that the magnetostrictive alternator may be combined in some embodiments with a Stirling engine to produce electrical power. The Stirling engine creates the oscillating pressure wave and the magnetostrictive alternator converts the pressure wave into electricity. In some embodiments, the magnetostrictive alternator may include aerogel material and magnetostrictive material. The aerogel material may be configured to convert a higher amplitude pressure wave into a lower amplitude pressure wave. The magnetostrictive material may be configured to generate an oscillating magnetic field when the magnetostrictive material is compressed by the lower amplitude pressure wave.

  • Patent number: 10581355
    Abstract: A double-fed oscillating linear alternator is provided that includes two concentric Halbach type arrays, one stationary and one movable, that do not require magnets or iron laminations to create a strong magnetic field between the two arrays where the movable array oscillates in a linear motion with respect to the stationary array. The two arrays are manufactured from magnet-less and iron-less conductive material using additive manufacturing techniques.

  • Patent number: 10507934
    Abstract: A thermal management system for an aircraft is provided that includes thermo-acoustic engines that remove and capture waste heat from the aircraft engines, heat pumps powered by the acoustic waves generated from the waste heat that remove and capture electrical component waste heat from electrical components in the aircraft, and hollow tubes disposed in the aircraft configured to propagate mechanical energy to locations throughout the aircraft and to transfer the electrical component waste heat back to the aircraft engines to reduce overall aircraft mass and improve propulsive efficiency.

  • Patent number: 10309376
    Abstract: A thermo-acoustic engine and/or cooler is provided and includes an elongated tubular body, multiple regenerators disposed within the body, multiple heat exchangers disposed within the body, where at least one heat exchanger is disposed adjacent to each of the multiple regenerators, multiple transducers axially disposed at each end of the body, and an acoustic wave source generating acoustic waves. At least one of the acoustic waves is amplified by one of the regenerators and at least another acoustic wave is amplified by a second one of regenerators.

  • Patent number: 10227950
    Abstract: A thermoacoustic engine is provided that uses acoustic energy to operate a piston in a double-acting action. The acoustic energy is amplified as a sound wave travels through the thermoacoustic engine. The amplified acoustic energy is extracted and converted into usable electrical energy.

  • Patent number: 9169855
    Abstract: A flow diode configured to permit fluid flow in a first direction while preventing fluid flow in a second direction opposite the first direction is disclosed. The flow diode prevents fluid flow without use of mechanical closures or moving parts. The flow diode utilizes a bypass flowline whereby all fluid flow in the second direction moves into the bypass flowline having a plurality of tortuous portions providing high fluidic resistance. The portions decrease in diameter such that debris in the fluid is trapped. As fluid only travels in one direction through the portions, the debris remains trapped in the portions.
