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.

I have already thought about this matter. I plan to hold a coronation ceremony in one month Su Yang smiled slightly and expressed his thoughts.Ah A shrill scream came from Liu Ruhua s mouth. I saw that her legs were cut off, dripping with blood, and it was too horrible to look at.
He wanted the city lord to see that he was not as unbearable as he imagined, and his opponent was not as bad as he described.They only need to send a few foundation building monks to patrol from time to time, which can save a lot of spiritual stones.
At that time, Xi Ling er shouted away the young man across from her in a few words, so it did not affect her interest in watching the excitement at all.For these three conditions, it is impossible for Qingyang to agree to any of them.
Thinking of this The long browed ghost king said One horned ghost king Although we are fighting for the pregnancy fruit this time and paying a huge price for it, this thing is yours.The ability to transform into the Buddha Vajra is all driven by the Happy Ghost King.
A Yuanying monk who has advanced to a level of cultivation over decades can already be considered relatively fast.Qingyang could feel that the toxins in his body were almost completely eliminated, and he would soon regain his strength.
Someone next to him saw this and said loudly I won t scare you to death if I say it.It can be said that they got a bumper harvest. Although most of them were relatively low level cultivation resources, there were some good things, such as the knot.
Soon, a terrifying aura was suddenly released from his body, but it was just a short time.After all, Xiao Yuhan s cultivation level was lower.
After coming here, Baimei Ghost King had thought several times whether he could reach here safely alone with his own ability.Moreover, the current situation has reached the point where it is either you or me, and there is no use worrying or being afraid.

are completely different things.How could it be prevented from reacting to the potion specially designed for it The reaction from the instinct of life made Bai Long covet the potion in Zhao Hao s hand, constantly signaling his creator to give it to him quickly.
But fighting in such a strong and open place is completely suitable for its performance.It was he who underestimated these people. They wanted to use the Filial Sword to lead the way, so they did not rush to take action.
Poof The flesh and blood body without any armor was easily pierced by the arrow.After all, compared to the aboriginal forces, their players were the weak ones and should work together to gain support.
After waiting at the place, they ignored Po Jun, Lao Tao and others who looked at the four dragon corpses with shocked faces, and left quickly Green Farms CBD Gummies Review – Everything You Need To Know [871ubnBkw]

action is too late.The third is that the position of the master of the first hall of the Ten Kings Palace is about to be changed, and all the ghost kings with ideas are here.
Yes, more than a hundred years later, the damaged stone statues are still there.Qingyang controlled his speed and walked all the way forward.
x At this time, True Lord Chujiang and the ancestors of the four families also came down.I couldn t resist her, so I had to let her go out to play.
However, as my father s fame became more and more , more and more monks come to him to refine weapons, which gradually affects Zhenjun Chiye s business.These Blood Demon Cult monks counterattacked frantically , actually recovered some of the decline, and injured several monks here.
A few years later, Zhenren Guihe finally broke through to the realm of Yuanying in one fell swoop and became a real Yuanying monk.He pinched his beard and said It is really possible.
At this time, Zhenjun Chiye had already seen clearly that the person who was smashing things in his mansion was actually the golden elixir monk who came to him to refine weapons.However, this matter was originally done by an insider, and Qin Ruyan, the headmaster s wife, helped to cover Top 8 Mounjaro Weight Loss Success Stories to Inspire Your Winter 2024 Journey [Y7n5c39vS]

They have never encountered such a thing for so many years of cultivation.Although he did not speak, everyone could tell that he was preparing to fight with the Fuliu Ghost King.
At this time, the treatment of Xiying s family of three is definitely not much better.I wish senior brother Long Eyebrow Ghost King longevity and good health.
Linglong Ghost King might even be faster than Huanxi Ghost King.Seeing that his feet couldn t break free, he used his spiritual thoughts to use the Netherworld Lihuo Sword, and slashed directly at the seaweed that entangled him.
Qingyang is not afraid of Zhenjun Shifu. What he is afraid of is that these Nascent Soul monks all wear a pair of trousers.
