NASA Hybrid Electric Hyper Efficiency Aircraft Concept

fuselage, as well as wingtip propellers. A single speed combustion engine drives the rear fuselage fan at very high efficiency, due to the Goldschmied fuselage propulsor. The wingtip propellers are driven by batteries to provide extra thrust for takeoff and climb, and act as wingtip vortex turbines at cruise to extract energy to recharge the batteries. The combination provides a variable disc loading propulsion system that can attempt to achieve optimal cruise efficiency (~200 passenger mpg, ...
