Nanomaterials describe, in principle, materials of which a single unit is sized (in at least one dimension) between 1 to 1000 nanometres (10−9 meter) but usually is 1 to 100 nm (the usual definition of nanoscale).
Enhancing the efficiency of propulsion can reduce fuel consumption and emissions in the air transport sector. Novel concepts such as multiple distributed propulsion systems and integration of propulsion into the airframe could help achieve goals.
