NASA's aero technology to save aviation industry billions

[botsapper]

NASA's Environmentally Responsible Aviation (ERA) project is pioneering new green technologies for the aviation industry. Technologies to reduce fuel consumption, aircraft noise and low-carbon aircraft.
Technologies include; new composite material fabrication, engine efficiency improvements, special outer coatings to reduce weight and air drag from insect strikes/splatter, weight reduction by recommending shorter tail fins with embedded air nozzles for better control, morphing wing shapes with multiple sealing flaps to close all flap/body gaps (reduces noise and efficient surfaces) and new hybrid wing body shapes.

Subsonic Ultra Green Aircraft Research (SUGAR) along with Boeing, created a concept to use distributed turboelectric powered engines for typical short-range flights. Efficient regular jet engines are used for more power in take-offs, then electric power supplement and even takeover the turbofans in lower/zero emission level/cruising flights. Plane concept designs to quieter, reduce fuel burn emission by 70% and be viable in 2030-2050 time frame.
