Revolutionary Propulsion Systems for 21st Century

Glenn Research Center, Cleveland, Ohio


Propulsion innovations have been the fundamental driver
to progress in air transportation. Enormous advances in
propulsion performance and efficiency have made it possible
for aircraft to travel at higher speeds over longer ranges while
carrying larger payloads. This has increased capacity by
orders of magnitude since the advent of air travel. The FAA
and commercial sectors are forecasting another dramatic
growth in commercial air transportation in the next 10 to 25
years. Commercial air transportation will again seek and rely
on advanced propulsion solutions to meet this ever-increasing
public demand.
