RESEARCH & DEVELOPMENT
grated power electronics and cooling, which have the potential
to enable power densities beyond 12 kW/kg for the full electric
drivetrain. Today, aircraft, using gas burning turbine engines,
achieve approximately 6-9 kW/kg. AML and its team have proposed a solution that includes a dual permanent magnet rotor
based on its PM-360 magnets, enhanced cooling allowing for
high current density stator coils, high-power density power converters, and a shared closed-loop cooling system. The PM-360
rotor eliminates the iron used in conventional motors.

" We are extremely excited to be
provided the opportunity to develop
and exhibit our capabilities and technologies for the future of aviation, "
stated Dr. Philippe Masson, CTO of
AML. The company is collaborating
with the Center for Advanced Power
Systems at Florida State University,
which is developing the high-power
density power converters which will
drive and control the motors. This
announcement is for Phase 1 of the
program, which is $654,354.

An award of $1.3 million went to
Texas A&M whose team will focus on
the design, fabrication, and testing of
a lightweight and ultra-efficient electric powertrain. The plan is
to reach peak power density and efficiency via an axial flux motor with lightweight carbon fiber reinforced structural material, a
GaN multilevel inverter, a thermally conductive nanocomposite

electrical insulation, and a two-phase thermal management system with zeolite thermal energy storage to absorb the excess
heat generated during takeoff. Each subsystem is designed for
tight integration with the other subsystems to minimize weight.
With a $2.9 million award, Hyper Tech Research aims to design
and demonstrate a multi-MW, high-efficiency, and high-power
density integrated electric propulsion motor, drive, and thermal
management system. Based in Columbus, OH, the company
provides superconductor solutions for medical and energy
products
It plans to incorporate an advanced and high-performance
induction electric machine with a novel advanced thermal
management technique for synergistic cooling that safely uses
cryogenic bio-LNG as the energy source for power generation
and a large thermal-battery cooling system to provide a highly
compact, light, and efficient thermal management system capability throughout all the different flight phases of a commercial
narrow-body aircraft. If successful, the system would allow for
a cost-effective motor capable of operating at a higher current
density compared with existing conventional non-cryogenic motors without using superconductors.
