There are many commercial cryogenic applications where this technology could be used. Specifically H2 circulators for neutron sources and flux reactors could both use this technology in applications that currently use short maintenance interval ball bearing machines. Also many cryogenic high-speed He compressors are needed for cooling superconducting magnets. Finally, cryogenic refrigeration systems require high-speed ompressors and expanders that would greatly benefit from this technology.
This special foil bearing technology will allowhigh speed, more efficient and reliable operation of cryogenic turbomachinery used in many NASA applications. These include propellant densification, cryogen subcooling for long term space storage, LH2 or LOX turbopumps and many other cryogenic pumps and compressors for ground support or space application.
