4. 4 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

5. 5 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.

7. 7 HALE - Barrier Breakthroughs Barrier: On-station extreme duration for HALE vehicles 1 st barrier up to 14 days 2 nd barrier more than 30 days Description: 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.
