Patent number: 11371431Abstract: 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.Type: GrantFiled: December 13, 2019Date of Patent: June 28, 2022Inventor: Rodger W. Dyson, Jr.

Patent number: 11303194Abstract: 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.Type: GrantFiled: July 2, 2019Date of Patent: April 12, 2022Assignee: United States of America as Represented by the Administrator of National Aeronautics and Space AdministrationInventors: Ralph H.

Patent number: 11183626Abstract: 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.Type: GrantFiled: December 13, 2017Date of Patent: November 23, 2021Assignee: United States of America as Represented by the Administrator of National Aeronautics and Space AdministrationInventors: Rodger W. Dyson, Geoffrey A. Bruder

Patent number: 10581355Abstract: 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.Type: GrantFiled: December 16, 2016Date of Patent: March 3, 2020Assignee: United States of America as Represented by the Administrator of National Aeronautics and Space AdministrationInventor: Rodger W.

Patent number: 9169855Abstract: 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.Type: GrantFiled: May 18, 2012Date of Patent: October 27, 2015Assignee: The United States of America as Represented by the Administrator of National Aeronautics and Space AdministrationInventor: Rodger W Dyson
