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.

In every city, in the streets and alleys, people can be seen talking about this matter everywhere.Boom In front of the Fearless Lion Seal, the Golden Lion King roared, his blond hair fluttering, and his whole Is Cbd Gummies Legal In Florida 340 A Comprehensive Guide body exuded a terrifying aura.
However, the opponent is obviously not an invincible king, and even like him, he is only a six star king.Then, a little snow white monkey appeared in the void.
This is a gorgeous dividing line And those warriors on the Golden Lingtai, many of them were directly blown away.It s getting bigger and bigger, like a black mountain, floating in the air.
Brother, 808 The Rising Popularity Of Truth Cbd Gummies Benefits Safety And Future Prospects brother. Buy a lilac flower. My lilac flower is white. Whose little girl is this, and she is cheating people here.The next moment, his fist shook, and the sky filled with flames shot up into the sky, forming two terrifying tornadoes, rolling in all directions.
But soon, Tuoba Tianci became stunned, because he found a handsome man walking out behind Murong Qingcheng.Look. Hahahaha, I really laughed to death. I guess this guy is trying to hide his face so that we don t recognize his identity.
Don t be too polite. Lin Xuan smiled. Unexpectedly, his status suddenly became a master uncle.Lin Xuan looked at the black flames with a satisfied smile on his lips.
They had never encountered such a vision before. They even thought of a legend, could it be an earth spirit master or a spirit seeker, which can be said to be a very special profession.He didn t expect that Gao Zhichao would use such a terrible method.
For a moment, everyone s eyes are on Lin Xuan and the first knife.Such people, if they don t enter now, they will be able to enter smoothly next time.
With a bang, the world was pierced in an instant, and the terrible gust of wind and storm killed Li Mengbai.At this moment, the Heaven and the Venerable Master, like a demon king, have the power to shatter heaven and earth.
Such a strange mountain, such a terrifying power, the two of them were shocked, they didn t expect such a good thing in Liuli Palace.The third prince looked at the figure behind him, his face became extremely ugly.
The momentum on the two of them is getting stronger and stronger, and a more intense collision is about to erupt.It seems that the battle for the prince is about to change again.
More than 100,000 people have come to watch. This scene can only be compared with the trials.Therefore, there will always be a large number of warriors entering.
The most important thing for a swordsman is self confidence, because this is the source of confidence in oneself.However, there is no evidence for either. The Holy Emperor also frowned, the source of the explosion was too far away from the seventh prince, otherwise, maybe a trace of clues could be caught.
You kid, what are you so arrogant about That is, don t think that you are invincible after catching that bitch Liu Mingyue.Enough to accommodate tens of thousands of people. And in this place, countless formations have been arranged by the dark red dragon to protect the safety of Lin Xuan and others.
The dragon sword field was shining with light, and countless fierce auras traversed the world, and the terrifying murderous intent penetrated all directions, making one s scalp tingle.Suddenly, a dragon chant sounded. Dragon Sword Spiritual Domain protects a green dragon that roars in all directions.
At this moment, they can no longer find a reason to think that the stone in front has a treasure.Because Lin Xuan entered the palace, it was no secret.
Lin Xuan also snorted coldly, black flames emanated from his body, spreading all over in an instant.In the days that followed, Lin Xuan didn t continue to gamble on stones, because he was too popular now.
Those who stay will be members of our League of Gods from now on.Yin Tianfeng s expression was incomparably cold. In his opinion, the person in front of him was just a rumor and didn t deserve his attention at Cbd Gummies With Thc For Anxiety Benefits Science And Reviews 71766 all.
Immediately afterwards, two figures flew back, and the light on their bodies became dim.He had practiced Wuying Tianluo before, but the straight line distance of Wuying Tianluo was not as good as the Demon God s Wings.
This battle is over, and the Necromancers snorted even more.Thinking of this, he sneered twice. Fortunately, he was smart and ran fast.
In the next moment, he crushed several formations inside the storage ring, and the heavenly materials and earthly treasures inside were shattered, providing him with powerful power.Dare to fight against the six great caves, and dare to challenge our Misty Peak, you really don t know how to live or die, kneel down and die, I will give you a good time, as for that Lin Xuan, we will tear him into pieces, let him know that life is better than death fate.
Who is this man His aura is not weaker than Longhuangzi s at all, even stronger.Those people outside the valley were terrified, who is this It is a real great saint.
Incarnation, he also knew a little bit about it. The previous Dragon Prince practiced incarnation, and he beheaded The Benefits Of Cbd Boner Gummies For Enhanced Male Performance Nuwal 735 one of them, but he still got injured, and it was not an ordinary minor injury.Congratulatory voices sounded one after another. As expected of the Dragon Prince, if you show your power, those heavenly soldiers and generals will be defeated.
I thought of a better way. Next, Xia Jiuyou expressed this idea.Those flames that fell from the other party were absorbed by his Nine Suns Divine Fire, making his physique stronger than before.
As he spoke, he waved his hand and turned into countless dragons, roaring in all directions.Looking at this scene, Lin Xuan was also terrified.
The two emperor level supernatural powers are the most terrifying supernatural powers he has ever encountered.How can his status and status be compared with that of an ant like you One person snorted coldly in the distance.
Damn Shashengdian, for the sake of a Comprehensive Zilis Cbd Oil Reviews A Detailed Analysis Of Benefits And Effectiveness 14 Tfoxe young man, is he going to start a war with our ten temples of Yama at all costs Damn it, the people from the Ten Temples of Hell are gnashing their teeth.They also know each other personally, but they are all masters at the peak level of the Holy King.
Let me go. This toad really dares to say it. Rear, asked, is there such a thing Yuhua Shengjun laughed, I think it must be a misunderstanding, right, Elder Ziyi He looked at the other party, the face of the elder in purple turned black, how could he refute, he said it was not a misunderstanding It is estimated that everyone will think that he is suppressing the younger generation.
Jia Qiniang took the deed of sale, glanced at it and handed it to Lin Haoming.There is no hillside in front of me, it is just a small hill, and in the center of the hill, Zhou Mengli and Hei Rui are still walking around among dozens of stone pillars.
Who would have said that if you were to be wiped out Besides, what do you think The law of heaven can control everything, if those heavenly kings want to make you disappear, do you think anyone will Revealed In The Success Of Cbd Gummies For Pain Among Athletes 28793 In Texas stop them But you are not a heavenly king, and you will leave a handle for you if you do this the killer said.
At the same time, Bao Wanchang and Mai Xinrou chased out together with Lin Haoming, and the others did not move.After experiencing life and death, he had already rewarded this servant girl heavily, but she was still so afraid of him.
He Rui didn t care about these three people, and directly revealed his identity as the commander of the thief city s arrest department, which shocked the three of them immediately.Information Zeng Wending Smilz Cbd Gummies 16745 Mg For Balanced Stress Relief was a little surprised when he heard it.
After Mg Cbd Gummies Review A Comprehensive 70 Analysis Of Benefits And Effectiveness Gtyaz looking at the sarcophagus, Lin Haoming asked Shu Siyue to find the letter about the mysterious corpse of Tianmai.In this way, after a while, even the fluctuation of vitality is calm, and there will be no more Some people will know that there was a fight here, and a former Taixu Realm cultivator accidentally died at the hands of two Mysterious God Realm juniors.
Seeing this scene, Cui Fei and Rong Ke felt desperate.Obviously, although he and Cui Changting act together, the relationship is still extremely bad.
It can be regarded as a first grade earth treasure.Before, Lin Haoming had seen and checked the material of the sarcophagus, and now he began to study the runes on the sarcophagus carefully.
When Lin Haoming got the method of manipulating the magic circle, his heart moved slightly, because the magic circle was obviously not complete, and it seemed that Fu Kuan really kept a hand.Before he caught the opponent s golden knife, his whole body flashed with light, and he instantly transformed into the body of a demon.
Although he had heard for a long time, what the demons absorbed was the magic energy.In this way, Han Ningxiang can tell her what to do next, especially Yinfengling.
but there must be someone to run errands. Since Bailifeng is so affectionate, I can let her be my errand runner, so that I can Gummy Ibuprofen For Adults A Comprehensive Guide To Pain Relief Jtdnk 97491 concentrate on my own things.After hearing the clerk s narration, the owner of Longgui knew that it was Lin Haoming and others who bought the maid, so he immediately ignored it.
Feeling her mother s tenderness, Yin Fengling seemed to feel relieved, and then continued to comfort her mother, telling her some of her own views on Lin Haoming.Master Tongtan, what s the matter Mrs. Yinye asked.
The man sat on the stool with a smile on his face and didn t answer.Mr. Yao, is this really okay Jia Qiniang asked in a low voice.
Fortunately, Mrs. Yinye took the lead and died at the end.Are you the person in charge here Lin Haoming asked casually.
Shu Siyue turned her head, only to see Lin Haoming appearing not far behind him, and next to him, whoever it was, was Yin Fengling.With a chance to escape, who would have thought that he would meet these two people.
When the gang leader arrives, he should give him some face, don t mention this matter again, and I don t want to see you again, get out Ren Chuanyue said that the more annoyed he was, he finally vented his anger on He Yingsheng.If you are not injured, I will It can be relieved by mixing some medicine, but you are so weak now, I m afraid you won t be able to take the medicine I prepared Life is a matter of fate, thank you girl for saving me, as long as I can keep Feng Ling, I
I
cough cough Stop talking, you hurt your lungs, if it Guide To Cbd Gummies In Washington Dc Benefits Legality And Where 2879 To Buy Izklw weren t for your mid term Taoist cultivation and your thick body, I m afraid you won t be able to hold on anymore.
I did so many things in Tongtianhe back then. I just thought that there would be such a day, and I have already prepared for it Bai Sanye gritted his teeth and said.Lin Haoming was wondering, Zhang Kaishi and Mai Xinrou also ran over quickly, barged in without knocking on the door and shouted in horror My lord, Tianyin
I see, let s go without any hesitation Lin Haoming immediately got up Koi Cbd 80979 Broad Spectrum Gummies Benefits Reviews And Guide and went out.
This Lin s firm is not owned by Lin Haoming. He killed our Jinfeng Gang, but let Jinfeng Gang make money for her.The other party s ship has already aimed its guns at us.
At this moment, a white rainbow suddenly appeared in front Go Love Cbd Reviews A Comprehensive Analysis Of 48227 Cbd Products For Enhanced Well of him, and then circled around Turning his neck around, Yao Kang, who had shown great supernatural powers before, had his head chopped off so easily without any resistance.The situation has changed. Lin Haoming took his gaze away from the other party, saluted with neither humbleness nor condescension, and said, Your official, Lin Haoming, has seen City Lord Yan The position of Zuo Tongzhi has been vacant for nearly ten years, and now there is finally a filling, which will also make the city master a little easier in the future Yan Yuyan said very politely.
You can go back and tell your subordinates. My lord, what did Mrs.As soon as Lin Haoming said this, someone immediately shouted I have a prescription for the magic tire pill here, I don t know Do you need it, Your Excellency Magic Embryo Pill, of course there is no problem Lin Haoming agreed immediately after hearing this.
Yinye is actually the niece of the previous gang leader.If you don t eat, if Madam asks me later, how do you answer, and you are still acting arrogantly.
Gangzi and the others were still a little surprised.The problem is that its bullets are too powerful and the range is only more than 200 meters, so it is called quasi intermediate power bullet.
Little Northeast, if he doesn t know the situation, he won t be able to keep up with Finding Relief With 871 Cbd Gummies For Neck Pain A Comprehensive Guide Iubzm the reaction speed So, each piece of information was sent to Wang Xuexin s battalion by telegram, and Chen Songyong reported to Wang Xuexin after sorting it out.Most of the bullets fired by the devils were empty, and several times the Jinsui army attacked the shore and hit the city gate.
He doesn t think this hand throwing petrol bomb is a big deal, and his greater concern is Wang Xuexin himself.I don t even know where he learned it from The chief and the chief of staff looked at each other and smiled.
What What did you say The chief asked in disbelief Say it again The chief Zhao Gang replied happily The transaction is completed.The rocket artillery unit prepared a total of more than a thousand rockets for this operation, which are all the rockets of the Eighth Route Army.
Wang Xuexin knew about this from the chief of staff.Less than one third of the fighters flying out each mission can return.
Therefore, although Mao Xiong lost the war, the reputation of T34 quickly spread around the world and became well known in the military circles of various countries.It is not an exaggeration to say that he has completely lost the hearts of the people.
At this moment, the soldiers are more like machines, numbly changing the magazine and pulling Discover The Best Cbd Gummies Harmony Leaf For Natural Relief And 9383 Wellness the trigger to knock down the enemies who rushed up.Immediately, all the troops of the squadron were gathered and lined up in a dense formation, which was still a long snake formation.
Zhao Gang was very satisfied with the training plan, so he sent it to the headquarters.Holding the mentality of watching the show , Thomas took his subordinates to the training ground of the mountain company the next day
Major Thomas task was to guide the mountain company to use these new equipment and perform maintenance and simple repairs.
Therefore, the veterans who have been on the battlefield for a long time tend to be more careful.If Earthmed Cbd Gummies Buy 9845 Online you want to use any words to describe this, it is a fake Dakong s face project.
As the so called military situation is urgent, Ningji Okamura was worried that Yuncheng would be captured by the Eighth Route Army if the speed was slow.Is the information confirmed Li Yunlong asked. Regiment leader Zhu Ziming replied, I will keep the captives, how about you interrogate them yourself Zhu Ziming was very relieved about this, because the captives didn t know the truth, so no amount of interrogation would work.
In history, the reason why Eagle Sauce rushed to attack Tokyo was because the Pacific battlefield was retreating steadily, especially the air battle, and the devils were almost unable to fight back, so they urgently needed to boost morale.If the tank company advances slowly, it may give the devils time to prepare.
Li Yunlong Immediately ordered Organize people to grab food at Luliang Mountain immediately Old Zhao Li Yunlong interrupted Zhao Gang s words I m talking about buying Let s gather all valuable things, including things brought by the common people, and take advantage of the time when the devils are still attacking Yuncheng and go to the Luliang Mountain area to exchange for one.
Now they are still asking for soldiers, and if they ask for a hundred, they are simply bandits Zhao Gang, who was sorting out the documents, felt a little strange when he heard it.What supplies How much Li Yunlong asked again. We will provide any materials Wang Xuexin said The first batch is estimated to be worth 10 million US 91985 The Benefits And Uses Of Maker Cbd Gummies A Comprehensive Guide dollars in the form of a loan
With a clang , Wang Xuexin heard the sound of the porcelain bowl shattering.
Isn t this place under our control We still have it.
