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.

Shan Yue felt a little moved when he saw the seal talisman on it.In order to seize the power of the gang leader, some gang members secretly gave birth to the daughter of the gang leader who was only a few years old at that time.
Although he had heard for a long time, what the demons absorbed was the magic energy.After finishing speaking, Lin Haoming planned to get out of the car, but at this moment, Song Ting called again Boss Lin, there is something that I think I need to tell you.
Everyone hid on the island. Before going to the island, Liu Xuan offered a pink handkerchief, which swelled to several feet in size Cbd Gummies Vs 07 Thc Gummies For Sleep Which Is Better For You in a flash of light.It was obvious that something was wrong with his body.
Compared with his disciples, the value of this elixir is much more important than cultivating a disciple.
Lin Xuan now has the identity of Hua Wufeng, so no matter his status or financial resources, he is the top.With this miraculous spiritual tea, it is believed that Shen Jingqiu s injuries can be completely repaired.

If people from Tianwu Continent were here, they would definitely scream out.The bloody sword slashed forward, and the entire void collapsed, even the killing swords couldn t stop it.
But then, he said in a low voice. Although Luo Jiang started the incident and humiliated the people around you, you can t kill him.For a while, the whole scene was very silent. The faces of the six kings including the Dark Red Shenlong changed drastically.
Keke Lin Xuan kept coughing, and every time he coughed, he spit out big mouthfuls of blood.nb Netizens please remind Please pay attention to rest your eyes when reading for a long time.
Angry, so angry that he was blown away again, and what s even worse, he didn t see who the other party was at all.This is a gorgeous dividing line However, there is a strong smell of blood in the sky, which indicates that there must be blood flowing.
This is a small sword that is not as low as any one person.What are you going to do Get rid of the person Surely if you do that, will the others have no idea Chen Shun asked worriedly.
Before Lin Haoming merged several forces, I finally decided to come out and leave only two big boats in Cbd 019 Gummies For Dog Anxiety Calming Your Pet my place, and bring small boats and a small number of people to the mighty North My Fortin Cbd Gummies Results 710 Korea.He only needs to build a huge water conservancy project, then everything can be changed, but even if the people in this world are relatively strong, they can t do it in a few years, but Lin Haoming Can afford to wait.
I was also the one who was in charge of the gate again, so I wanted to get into the woods, but at that moment, a strange voice asked mockingly Captain Cheng, why are you planning to retreat outside the gate When no one thought that things would be deadlocked, Li Shuxian suddenly let out a small Reliva Cbd Cream 782 Review A Comprehensive Analysis Of Cbd For Pain Relief Gjyuw cry, and after that, no one saw you as if you were thrown out.
