PEFCs to transform UAVs
Advancements in polymer electrolyte membrane fuel cells have
resulted in longer endurance missions for smaller UAVs as well as
an enabler for electric aircraft that require vertical takeoff and
landing capability.
Hovering aircraft programs
The AW609 tiltrotor and the X3 compound helicopter offer different
technology solutions to the challenge of achieving higher speeds
and higher quality point-to-point air transport.
