Airbus, Rolls-Royce y Siemens han formado una alianza para desarrollar, a corto plazo, un demostrador de vuelo que será un paso importante en la propulsión híbrida eléctrica para los aviones comerciales. Las tres compañías anunciaron esta colaboración sin precedentes, que reúne los mejores expertos mundiales en tecnologías eléctricas y de propulsión en la Royal Aeronautical Society de Londres.
Se prevé que el demostrador de tecnología híbrida-eléctrica E-Fan X volará en 2020 tras una campaña de amplias pruebas en tierra, provisionalmente en una plataforma de pruebas volante BAe 146, con uno de los cuatro motores de turbina de gas de la aeronave sustituido por un motor eléctrico de dos megavatios. Se establecerán disposiciones para sustituir una segunda turbina de gas por un motor eléctrico una vez probada la madurez del sistema.
“El E-Fan X es un paso importante hacia nuestro objetivo de hacer realidad el vuelo eléctrico en un futuro próximo. Las lecciones que aprendimos de una larga historia de demostradores de vuelo eléctricos, empezando por el Cri-Cri, incluso el e-Genius, E-Star y culminando recientemente con el E-Fan 1.2, así como el fruto de la colaboración E-Aircraft Systems House con Siemens, abrirán el camino hacia un avión comercial de pasillo único híbrido que es seguro, eficiente y rentable”, comentó Paul Eremenko. “Consideramos la propulsión híbrida eléctrica como una tecnología convincente para el futuro de la aviación”.
El demostrador E-Fan X explorará los desafíos de los sistemas de propulsión de alto rendimiento, como efectos térmicos, gestión del empuje eléctrico, efectos dinámicos y de la altitud sobre los sistemas eléctricos y problemas de compatibilidad electromagnética. El objetivo es empujar y dejar madurar la tecnología, el rendimiento, la seguridad y fiabilidad para progresar rápidamente sobre la tecnología híbrida eléctrica. La finalidad del programa también es establecer los requisitos para una futura certificación del avión eléctrico formando a una nueva generación de diseñadores e ingenieros para acercar el avión comercial híbrido eléctrico un poco más a la realidad.
Como parte del programa E-Fan X, Airbus, Rolls-Royce y Siemens contribuirán cada uno con su amplia experiencia y sus conocimientos en su respectivo ámbito de competencia:
– Airbus se encargará de la integración global así como de la arquitectura de control del sistema de propulsión híbrido eléctrico y las baterías, y su integración con los mandos de control de vuelo.
– Rolls-Royce se encargará del motor turbo-shaft, del generador de dos megavatios y de la electrónica de potencia. Junto con Airbus, Rolls-Royce también trabajará en la adaptación del ventilador a la góndola existente y al motor eléctrico de Siemens.
– Siemens entregará los motores eléctricos de dos megavatios y su unidad de control de la electrónica de potencia, así como el inversor, convertidor DC/DC y sistema de distribución de la alimentación eléctrica. Todo ello viene a añadirse a la colaboración E-Aircraft Systems House entre Airbus y Siemens, lanzada en 2016 y cuyo objetivo es desarrollar y dejar madurar varios componentes de sistemas de propulsión eléctrica y su demostración terrestre con diferentes gamas de potencia.

Paul Stein, Chief Technology Officer para Rolls-Royce, dijo: “El E-Fan X nos permite aprovechar nuestros amplios conocimientos eléctricos para revolucionar el vuelo y entrar en la tercera generación de la aviación. Son momentos muy emocionantes para nosotros puesto que estos avances tecnológicos harán que Rolls-Royce cree el generador de vuelo más potente del mundo”.
“Siemens ha impulsado la innovación en ámbitos tecnológicos esenciales a toda velocidad”, añadió Roland Busch, Chief Technology Officer para Siemens. “En abril de 2016, abrimos un nuevo capítulo en la movilidad eléctrica con la colaboración de Airbus. Desarrollando la propulsión eléctrica de los aviones, estamos creando nuevas perspectivas para nuestra empresa y también para nuestros clientes y nuestra sociedad. Con la colaboración E-Fan X, damos ahora el siguiente paso para demostrar la tecnología en el aire”.
Uno de los desafíos del sector de la aviación actual será avanzar hacia un medio de transporte con mejores prestaciones medioambientales, más eficiente y que dependa menos de los combustibles fósiles. Los socios se han comprometido a alcanzar los objetivos medioambientales técnicos europeos del informe de la Comisión Europea «Flightpath 2050 – Vision for Aviation» (reducir las emisiones de CO2en un 75%, reducir los NOx en un 90% y reducir el ruido en un 65%). Estos objetivos no pueden alcanzarse con las tecnologías que existen en la actualidad. Por consiguiente, Airbus, Rolls-Royce y Siemens están invirtiendo y orientando los trabajos de investigación hacia diversas áreas tecnológicas, incluso la electrificación. La propulsión eléctrica y la propulsión híbrida eléctrica se consideran entre las tecnologías más prometedoras para afrontar estos retos.

He never thought about the possibility that the two late stage Qi refining monks would escape.The most basic magic runes include spirit storage runes, acceleration runes, solidity runes, slowness runes, fire runes, frost runes, etc.
At this moment, he no longer had the last thought about that inheritance.He didn t tell Fan Yiyang that he was coming to the palace, so how could Fan Yiyang think of saying this.
Not to mention other weapon makers, even Li Shiming himself, as long as he has the raw materials of spiritual wood, he can make countless Senluo Lings that are exactly the same, and it is impossible to tell the real ones from the fake Apple Cider Vinegar For Weight Loss | Can It Really Reduce Belly Fat? [LExnFbru3y4] - Digital Writing ones.Even if his level is similar to that of Elder Sword , can even fight with Elder Jian.
This is the address for participating in the monk market.He forgot everything, absorbed the purple energy every morning, and then practiced the Vajra Body Protection Magical Technique and the Sword Demon Secret CBDfx ベイプキットMini の使い方 [IXpFLFQZUs1] - Digital Writing Code , and spent the rest of his time practicing the Nine Heavens Thunder Strike Technique.
Brother Li, fight quickly and don t waste time Xu Chuan reminded softly.The secret technique left in Baili Jinyan s body has lost its induction, but it has not disappeared.
Of course, the Fiery Flame Sword still couldn t be controlled by the Expelling Object Technique , and he probably guessed the reason why.The headless Xuanming Sect Qi Refining cultivator collapsed suddenly, and his head rolled away several meters away.
If we really pursue the case, he, the prefect, may not even be able to save his life.It was this white jade cup that brought him a sense of oppression.
Just when he was about to return to the cave, news came from the identity jade disc.Even though the seven casual cultivators were the Half Cocked / Male Enhancement [yMMYUILqEZI] - Digital Writing lowest in strength, even at the lowest level they were at the same fourth level of Qi refining as him.
You must know that many studies in previous lives were limited due to material issues, but this world has unique advantages in materials.In the temporary stall, he also saw people exchanging secular calligraphy and painting treasures for spiritual stones, but he didn t know what kind of monk would exchange spiritual stones for those things.
The quality of this long sword is even higher than that of high grade magic weapons.Lan er misses you so much When Yin Shilan said this, she didn t know what she thought of, and tears of grievance filled her eyes.
Digression Thanks to My Love Weak Water Three Thousand for the reward of 10 yuan Li Shiming didn t know why, but the formation tasks had become much heavier in recent times.But now it seems that all the elites of the Yun clan will be charged with betraying the clan.
It seemed that the law enforcement monk had sinister intentions.
Suddenly Zhao Hao chewed on Mia s description. If you describe it like this, it is definitely not unreasonable.Two special circumstances created completely different roles for Bailong at sea and on land.
But the arrogant elf didn t give him any face, so he kept sinking for decades.tumultuous However, two golden daggers that were also burning with flames cut the fireball, and pierced his body with the daggers like lightning, instantly igniting his body.
The opponent s strength is indeed good, but he doesn t have much combat experience, so he can easily solve it with a simple trick.He had not had the ability to make several people take him seriously with just one word before.
The flames are killing the cultists Unlike the military units on the battlefield, which often suffer thousands or tens of thousands of casualties, this is because cultists know how to hide, retreat, etc.Buzz The flashing magic lines provided power for the Storm, causing the speed to instantly rise to the same as that of a steel battleship, neither a minute faster nor a step slower.
