Extract From NASA Blueprint for the future
Revolutionary Vehicles: Development of supersonic aircraft capable of global travel to any point within 10 hr. and reducing transcontinental flight times by 50% are goals. Other technologies include creation of new materials, morphing airframe structures, micro surface actuators, intelligent and adaptive flight control systems, hybrid propulsion, hydrogen-oxygen fuel cells and advanced computational tools. Noise reduction of 20dB. and cutting engine emissions up to 50% are key priorities.
