Besides stator coils for the all-electric aircraft, magnesium diboride superconductors can benefit NASA for many applications where light weight power components are required such as generators, motors, transformers, inductors, power conditioning equipment and ADR coils. Other magnet applications that magnesium diboride wires can be considered for are magnetic bearings, actuators, MHD magnets, propulsion engines, magnetic shielding in space, and magnetic launch devices.
For Non-NASA commercial applications, MgB2 superconductor wires for DC applications are: rotor coils for motors and generators, background magnets for MRI systems to eliminate liquid helium bath cooling, inductive type superconducting fault current limiters. Low speed 5-20 MW direct drive wind turbine generators. For AC applications fine filament MgB2 wire being developed in this Phase II would benefit 50-400 Hz stators for generators and motors, transformers, reactors, inductors, and resistive fault current limiters.
This SBIR Phase II proposal overcomes technology barriers for developing highly efficient all electric aircraft systems for the future, with limited impact to the environment. Turboelectric propulsion for aircraft applications is envisioned, and cryogenic and superconducting components are sought. In particular, low AC loss superconducting wires for the stator windings and superconducting wires with filaments less than 10 micrometers in diameter are of interest. There is an intense push in the aircraft industry to ultimately develop an all-electric aircraft, with liquid hydrogen and fuel cells being considered as the prime generation source for aircraft propulsion. The U.S. is in competition with Europe for the development the next generation all-electric aircraft. Superconductivity especially magnesium diboride (MgB2) superconductors are considered an enabling technology that is being investigated by NASA, Air Force, Rolls-Royce, Airbus and EADS. This means the need for a low cost, low AC loss (fine filament superconductor) that can operate in the 10-25K temperature range in 0-2 tesla fields for superconducting stators for motors and generators. This wire is need by 2016-2017 time frame so all cryogenic motors and generators can fabricated and tested in the NASA test bed. In the Phase I Hyper Tech has shown that fine filament MgB2 wires can be fabricated and there is potential for low AC losses in the 60-400 Hz range for stators. In the Phase II Hyper Tech will continue to work on developing, manufacturing, and testing fine filament MgB2 wire. The wires will also be twisted to reduce coupling losses. The wires will be tested for their superconductor and engineering current density and AC losses. The result of this work will be a low AC loss MgB2 superconductor wire for enabling all-electric aircraft development and allow the U.S. industry to lead the world in this needed and rapid developing technology.

If you are a small business concern (SBC) with 500 or fewer employees or a non-profit RI such as a university or a research laboratory with ties to an SBC, then NASA encourages you to learn more about the SBIR and STTR programs as a potential source of seed funding for the development of your innovations.
The SBIR and STTR programs have 3 phases:
The SBIR and STTR Phase I contracts last for 6 months with a maximum funding of $125,000, and Phase II contracts last for 24 months with a maximum funding of $750,000 - $1.5 million.
Opportunity for Continued Technology Development Post-Phase II:
The NASA SBIR/STTR Program currently has in place two initiatives for supporting its small business partners past the basic Phase I and Phase II elements of the program that emphasize opportunities for commercialization. Specifically, the NASA SBIR/STTR Program has the Phase II Enhancement (Phase II-E) and Phase II eXpanded (Phase II-X) contract options.
