Potential Benefits for Civil Aviation:

Al Bowers, NASA, 2000


Reduced wetted area to volume ratio by up to 33%:

friction drag fuel burn environmental impact Direct Operational Cost (DOC)

Increased lifting surface: about 20% increase in maximum Lift/Drag (L/D) ratio

Reduced noise: engines placement above the wing and streamlined geometry

Increased PAX capacity: Reduced Airport-Airspace congestion and reduced Fairs

12% DOC, 21% Fuel efficiency, 6% Gross weight, 17% Greenhouse gas emission 7

Manufacturability


Year 1: design, build, test, and fly a 3D Printed, low speed UAV with BWB configuration • Mission profile: RC controlled UAV to fly at maximum altitude of 10,000 ft and

maximum speed of 0.2 Mach (225 fps) • Airframe: hybrid airframe (composite (skin)/lattice material (primary structure)) • Payload: zero • Power-plant: Electric

Year 2: add VTOL capability to the BWB-UAV

Year 3: Expanding payload capability and modify design accordingly

Year 4: Expanding UAV mission profile to transonic/supersonic speed employing hybrid power-plant (rocket/jet engines)

Milestones:

Aircraft Structural Development in Aerospace Industry
