Our success is measured by the extent to which our results are used by others to improve the quality of life and
enable exploration and scientific knowledge
To provide advanced aeronautical technologies to meet the challenges of next generation systems in aviation,
for civilian and scientific purposes, in our atmosphere and in those of other worlds.

Vehicle Systems Program
• GOAL:– Provide breakthrough technology for
significantly advanced future air vehicles.• APPROACH:
– Develop technologies and demonstrate them in flight to provide evidence of barrier breakthroughs.
• BENEFITS:– Opens more communities to air transportation– Enables new air transportation models by doubling
vehicle speed capability– Eliminates aviation pollution– Enables new science platforms

Demonstration Projects
ZERO EMISSIONS AIRCRAFT — Start by demonstrating an aircraft powered by hydrogen fuels cells.
SUBSONIC NOISE REDUCTION — Start by demonstrating a 50% noise reduction compared to 1997 state of the art.
SONIC BOOM REDUCTION — Start by demonstrating technology that could enable an acceptable sonic boom level.
HIGH ALTITUDE LONG ENDURANCE — Start by demonstrating a 14-day duration high-altitude, aircraft.

HALE - Barrier Breakthroughs
Barrier: On-station extreme duration for HALE vehicles • 1st barrier up to 14 days • 2nd barrier more than 30 daysDescription: Demonstrated endurance of HALE systems to date limited to less that
3 days (SOA Boeing Condor, 1989).• HALE systems require significant support personnel and ground station
infrastructure to operate, while not yet achieving levels of safety and reliability equivalent to piloted systems.
Objectives: • Project will develop specialized technologies that enable extreme duration flight:
– ultra-lightweight structural concepts, – highly-automated uncrewed flight systems capable of achieving required
levels of safety and reliability, – efficient fuel cell/solar based regenerative propulsion systems.
• Project will integrate technologies into a commercially viable flight system and verify the achievement of desired capability goals through flight demonstrations.
• HALE Demonstration Project will enable new capabilities for the NASA science and exploration missions.
