NASA : NASA's X-57 Electric Research Plane .- Avión de NASA X-57 de Investigaciones Eléctricas.-

Hola amigos: A VUELO DE UN QUINDE EL BLOG., Con 14 motores eléctricos girar las hélices y todos ellos integrados en un ala de diseño único, la NASA probará nueva tecnología de propulsión utilizando un avión experimental designado ahora el X-57 y apodado: "Maxwell."  Esta concepción artística  X-57 muestra el ala especialmente diseñado de avión y 14 motores eléctricos. los investigadores de la NASA Aeronáutica utilizarán el Maxwell para demostrar que la propulsión eléctrica puede hacer aviones más silenciosos, más eficientes y más respetuosos con el medio ambiente.

“With the return of piloted X-planes to NASA’s research capabilities – which is a key part of our 10-year-long New Aviation Horizons initiative – the general aviation-sized X-57 will take the first step in opening a new era of aviation,” said NASA Administrator Charles Bolden, during his keynote speech Friday in Washington at the American Institute of Aeronautics and Astronautics (AIAA) annual Aviation and Aeronautics Forum and Exposition.


NASA’s aeronautical innovators hope to validate the idea that distributing electric power across a number of motors integrated with an aircraft in this way will result in a five-time reduction in the energy required for a private plane to cruise at 175 mph.

Several other benefits would result as well. “Maxwell” will be powered only by batteries, eliminating carbon emissions and demonstrating how demand would shrink for lead-based aviation fuel still in use by general aviation.

Energy efficiency at cruise altitude using X-57 technology could benefit travelers by reducing flight times, fuel usage, as well as reducing overall operational costs for small aircraft by as much as 40 percent. Typically, to get the best fuel efficiency an airplane has to fly slower than it is able. Electric propulsion essentially eliminates the penalty for cruising at higher speeds.

Finally, as most drivers of hybrid electric cars know, electric motors are more quiet than conventional piston engines. The X-57’s electric propulsion technology is expected to significantly decrease aircraft noise, making it less annoying to the public.
