Using supersonic metal particle sprays to get get powder fusion via kinetic impact, not too far from older metal cold spraying techniques. Not using bulk heating so less likely to have warped parts from SLS/SLM methods. Doing aerospace grade titanium, with an ITAR compliance area as well?

European Space Agency Awards €500k for New Cold Spray 3D Printing Technology
Interesting, using cold helium to increase the speed of sound of the neutral carrier gas for a metal powder spray, so it uses impact bonding rather than some kind of laser heating.

Starkey Aerospace Corporation
Some kind of new microturbine design that claims double the fuel efficiency of other engines in its classfor high subsonic/low supersonic UAV propulsion. The aim is to make SST research more affordable, as well as advanced cruise missile work. Also claiming a lube free engine (air/foil/hydrodynamic bearings?)

CAITIN-Advanced Vortical Cooling Technology
Interesting concept for a supersonic vortex refrigerator. I'm not clear how this works, since it would seem to at the least still require a circulation pump, which functionally wouldn't be all that different from a conventional compressor...

A different carbon capture setup, sending slightly pressurized exhaust gas through a supersonic cyclonic separator that freezes the CO2 and water out of the exhaust. Also claims 50% reduction in parasitic load. Basically the same as a twister setup for natural gas cleaning.

Apple Invents New Peer-to-Peer Sharing Technology that Utilizes Unique Magnetic Compass and Supersonic Tone Methodologies - Patently Apple
Interesting tricks here. Doing P2P PAN peer device discovery/pairing by detecting a nearby device's magnetic signature using the onboard conventional magnetic compass (3 axis magnetometer?), as well as using supersonic (ultrasonic?) modulation of it's own speaker to tweak it's own magnetic signature as an ID beacon or coded message.

超音速複葉翼理論
Japanese research about Busemann Biplanes, which use a curious supersonic wave convergence effect to recovery energy lost due to wave compression by using converging waves to create a virtual thrust nozzle. Unfortunately, it isn't simple to utilize as the separation between wings changes next with respect to mach number. Most tricks to fix this had the wing spars on rotating bearings, with both bearings mounted on a rotating circular plate. with both bearings at top/bottom dead center, you have max separation. Rotate the plate, and the upper wing moves forward and down, while the lower wing moves back and up. This changes the vertical separation.
