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 evaluate
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 propulsion systems.
Improves measurement: Standardizes measurement of electric engine efficiencies
Novel: Implements sensors in a unique way to enable testing configurations
Electric aircraft engines, generators, controllers, and batteries

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.
