Turbo-Electric Distributed Propulsion
An Armstrong team is
developing a static test stand for single-engine electric aircrafts.
Researchers will use this technology to identify ways to measure motor and
battery efficiencies; evaluate multidisciplinary dependencies; and provide
insights into propeller, motor, and electronics designs specific to electric
aircraft propulsion. The ultimate goal of the project is to determine a
standardized way to measure electric engine efficiencies.
Work to date: In 2013, the team
began constructing the test stand and researching electric
propulsion test motors. Small-scale versions of the stand were also designed
and built to demonstrate the effectiveness of test sensor installation
techniques and measurement technology required for the full-scale design.
Looking ahead: The group will complete construction and
static testing and mount the stand on a truck for dynamic testing.
A ground testbed for performance and control characteristics will be used to
new electric propulsion technologies that could be applied to
vehicle integration. This research has already spawned interest in a follow-on
proposal from NASA's Hybrid Electric Integrated System Testbed (HEIST) project,
which is investigating power management and distribution for hybrid electric

Efficient Aerospace Vehicle Technologies
Increasing efficiency in aerospace systems is a key goal across
the spectrum of NASA operations.
Armstrong researchers are constantly striving to build
efficiency into all phases of flight projects, through development,
fabrication, and operations processes.
From a new wing design that could exponentially increase total
aircraft efficiency to a novel test stand for single-engine electric aircraft,
our researchers are finding unique solutions that increase efficiency.
