NASA showcasing electric X-57 “Maxwell” airplane at AirVenture Oshkosh 2018

Among its exhibits at AirVenture Oshkosh 2018, held next week at Wittman Regional Airport in Oshkosh, Wisconsin, NASA will showcase the all-electric X-57 Maxwell aircraft (earlier post). The X-57 takes to the skies in 2019 to demonstrate how electric propulsion can be 500% more efficient than conventional aircraft.

On 23 July, NASA’s Jeffrey Vike will present a talk on the X-57 at the event. The goal of the NASA X-57 Electric Airplane was to utilize the versatility and efficiency of electric propulsion to design a cruise-optimized airplane. The wing planform was reduced 42%. A slotted flap and distributed fan system were developed to achieve CL’s in excess of 4.0.

Viken will discuss performance objectives, features of the wing and high-lift system, as well as integration considerations. He will also present CFD performance analysis and details of the integrated structure.



Add a Hydrogen Fuel Cell and reduce the battery weigh...then you would have a practical airplane.


A good application for recent vey high power/weight ratio FCs.

A few batteries or launching facilities to help quicker takeoffs and extend range?

H2 trucks/tankers could be used for very quick refill.


Electrified airplanes, with 500% better efficiency than current airplanes ,could drive inefficient short range JET planes out of business with much lower fares, specially the fully automated (pilotless) version.
