Justo después del amanecer del 22 de mayo, Facebook alcanzó otro hito emocionante e importante en el proyecto Aquila –completamos exitosamente nuestro segundo vuelo a escala real de la aeronave–. Esta voló por 1 hora y 46 minutos y aterrizó a la perfección en nuestro sitio designado.
Para poder lanzar la aeronave antes del amanecer, que ese día fue a las 5.15 a. m., estábamos en la entrada del Campo de Pruebas Yuma (YPG) en Arizona desde las 12.30 a. m. Mientras que unos miembros de nuestro equipo empezaban a abrir el hangar y levantaban la aeronave hasta su base de despegue, el resto de nosotros preparábamos las estaciones de control en tierra e ingeniería. Prácticamente todos revisamos las predicciones sobre vientos, constantemente.
El segundo vuelo de Aquila tuvo en cuenta todas las lecciones aprendidas durante nuestro primer vuelo. Antes de este, incorporamos una serie de cambios a Aquila que incluyeron:
La adición de spoilers a las alas, que incrementan resistencia y la propulsión en el acercamiento al aterrizaje.
Incorporamos cientos de sensores para recolectar más datos
Modificamos el software de piloto automático
Integramos nuevos radios al subsistema de comunicaciones
Cubrimos la aeronave con un acabado más liso
Instalamos un mecanismo de detención del propulsor horizontal para poder tener un aterrizaje exitoso.
A las 5-27 a. m., cuando el sol estaba apenas encima del horizonte comprobamos que la aeronave pasara todas nuestras verificaciones anteriores al vuelo: los vínculos de radio (redundantes tanto para la carga como descarga y con ancho de banda extra) eran funcionales, las superficies de control y los spoilers estaban libres y eran correctos y los cuatro motores respondían adecuadamente a los comandos.
Tras completar nuestra lista de verificación anterior al vuelo, nuestra corta espera fue premiada con poco viento medido y poco viento en las predicciones del clima. Un breve sondeo de nuestros pilotos e ingenieros nos dio luz verde para el lanzamiento. La velocidad de despegue estuvo calculada en 43.45 km/h, lo que notificamos a nuestro remolque. El equipo observó de cerca todas las pantallas, esperando la seña que confirmara que el piloto automático hubiera tomado el control y que la aeronave ya estaba subiendo, lejos de su base de despegue.
El lanzamiento fue normal. También se hizo evidente prontamente que todos los sistemas funcionaban normalmente: la corriente del motor, el seguimiento a la velocidad del aire, los indicadores de dirección, vínculos de radio y GPS diferenciales mostraban todos comportamientos normales. La única sorpresa que tuvimos fue del tipo alegre: la tasa de ascenso –54.86 mt/s– fue casi el doble de la de nuestro primer vuelo, lo que atribuimos a los múltiples ajustes de Aquila –puntualmente el acabado más liso– que implementamos desde el primer vuelo.
Así, continuamos nuestro ascenso hasta los 914 metros, esperando todas las señas que mostraban el buen estado de la aeronave antes de que esta excediera nuestro rango de vuelo planeado. Con todas las telemetrías “en negro”, continuamos subiendo. Por diseño, Aquila se toma su tiempo: asciende lentamente, desciende incluso más lento y cuando vuela con el viento no lo hace a más de 16-22 km/h respectivo al suelo. Hemos diseñado Aquila de esta forma porque su fin es quedarse en la misma zona por largos periodos de tiempo proveyendo acceso a internet. Aquila se alimenta de energía solar y es extremadamente eficiente –funciona con la electricidad equivalente de tres secadores de pelo–.
El segundo vuelo se trataba solo acerca de datos. Volamos para surtir largas pruebas a una velocidad, inclinación y altitud constantes para medir la resistencia de la aeronave. Los datos de estos “trim shots”, como los llamamos, serán usados para refinar nuestros modelos aeronáuticos, lo que nos ayuda a predecir mejor el consumo energético y, así, optimizar el uso de nuestras baterías y la ubicación de los paneles solares. También instrumentamos extensamente la estructura del avión, agregando cientos de sensores a este para entender cómo la forma de Aquila responde al vuelo en tiempo real. Estos incluyendo cientos de medidores de esfuerzo y tres ejes de medición de inercia (IMU). Estas herramientas nos sirven para verificar y refinar nuestro modelo estructural, lo que predice la firma estática de la aeronave –además, diseñada para ser muy flexible y responder tanto a los vientos como a las maniobras–.
Durante todo el vuelo, continuamos monitoreando la resistencia creada por los nuevos spoilers de Aquila en diferentes ángulos. Estos spoilers son estructuras móviles en el ala de una nave que le permiten incrementar la resistencia para reducir la velocidad y la propulsión. También probamos la fuerza de señal de los dos vínculos radio desde varios puntos angulares.
Después de probar el algoritmo de aterrizaje con una versión elevada, hemos puesto la nave a hacerlo de forma completa, y exitosa, en el lugar designado.
Aquila no tiene un mecanismo de aterrizaje en el sentido tradicional. En cambio, aterriza sobre bases de Kevlar unidas a la parte baja de las cápsulas del motor. Nuestro razonamiento para esto se debe a dos razones: primero, aterrizamos a una velocidad respecto al suelo y nos acercamos al suelo de forma muy lenta, para que podamos disminuir el peso y la resistencia en las riostras y ruedas; y, segundo, porque mucho del peso de la aeronave está concentrado en las cápsulas del motor, pues es acá que están instaladas las baterías. Una vez las baterías han tocado suelo, detener el descenso del resto de la aeronave no representa un gran esfuerzo para la estructura.
Para la base de aterrizaje creamos un círculo de 152 metros de gravilla de unos 15 centímetros de profundidad con la consistencia de arena gruesa. El vuelo de Aquila es autónomo salvo por intervenciones manuales, como las necesarias para alinearse con el viento. Por lo tanto, justo antes del aterrizaje, el equipo de vuelo carga un plan de aterrizaje basado en la dirección del viento para que la aeronave aterrice con el viento y respetando el límite de vientos cruzados.
Al aterrizar Aquila sigue un camino de descenso con inclinación de 3 grados que empieza en el aire y termina en el piso. Una característica de este tipo de aeronaves es la baja resistencia –es la única forma posible de volar con la energía limitada que provee la luz solar–. Pero mientras la resistencia es el archienemigo del vuelo, ella es la primera aliada del aterrizaje. Los spoilers que agregamos a la aeronave son controlados por el piloto automático. Cuando este siente que la nave excede la inclinación, cierra los spoilers. Cuando siente que está pode debajo, los abre más. Mientras tanto, como durante todo el vuelo, el piloto automático sube y baja su punta usando elevons, que ayudan a incrementar o reducir la velocidad de vuelo.
A unos segundos del aterrizaje, el piloto automático detiene los motores del avión y los bloquea automáticamente. Se bloquean así para evitar dañarlos durante el aterrizaje. Todos los motores están detenidos, pero solo uno de los propulsores está horizontal. La aeronave hizo contacto gentilmente en la superficie de aterrizaje y se detuvo en unos 10 metros. Fue absolutamente perfecto. Igual que cuando se conduce un auto en gravilla, aterrizar la aeronave en este material causa apenas unos pocos y fáciles de reparar rayones. En todos los otros aspectos, Aquila aterrizó en la mejor forma.
Desde nuestra estación de ingeniería, en las cercanías, el equipo de Aquila vimos una transmisión de video que nos mostraba la vista desde el aire, tomada por nuestro helicóptero de seguimiento. Tuvimos asientos de primera fila para ver a la aeronave deslizarse suavemente hasta la quietud en una nube de polvo –y ver a la estación de ingeniería levantarse en aplausos–. Después del aterrizaje de Aquila, el equipo de YPG informalmente bautizó el área de aterrizaje como “Playa Aquila” –¡nombre que nosotros estuvimos orgullosos de adoptar!–.
Sobra decir que el equipo entero estaba sumamente feliz con estos resultados. Nuestro objetivo de conectar a la gente con aeronaves de vuelo a gran altitud y con energía solar es valiente, pero hitos como el marcado por este vuelo hace que meses de arduo trabajo valgan la pena. Por eso, es particularmente gratificante, que las mejoras hechas según el desempeño de Aquila en su primer vuelo hicieran una diferencia significativa en este segundo vuelo.

Existen muchas ventajas al incorporar inteligencia artificial, ya que atienden tres pilares fundamentales: Predicciones y previsiones, detección de anomalías y pronóstico de rendimiento de la organización.
IDC calcula que las empresas dedicarán al menos 28% de su presupuesto de TI a la contratación de servicios en la nube durante 2017, con lo que inician la transición a un modelo de consumo bajo un esquema de Opex (gasto operativo).
El año 2024 se presenta como un periodo emocionante y desafiante para la fabricación aditiva. Los avances tecnológicos, las tendencias sectoriales y la evolución en la gestión de la cadena de suministro están destinados a redefinir la industria, marcando un camino hacia un futuro donde la impresión 3D desempeñará un papel cada vez más crucial en la fabricación moderna.
From the information received from the surveillance, both Elder Baili and the Foundation Establishment monks guessed that the two late stage Qi refining monks had gone to assassinate him, so it was normal for the items of the two late stage Qi refining monks to be in his hands.But under the infrared probe, the thermal image of Lao Si was clearly exposed to Li Shiming s eyes.
Usually this situation shows Jin Shufeng s special status.If he saves five breaths of time, he can also increase the maximum distance to three hundred meters, which is the farthest teleportation distance he can achieve.
If two are not enough, then use more. Of course, the middle grade magic weapon Gatlin needs to be controlled.He saw that the three foundation building monks of the Tie clan were still attacking, but the attack frequency was no longer so intensive.
He quickly analyzed and calculated his winning rate in the battle.When flying close to Duifeng, I received a reply allowing the assessment.
This is still skin, Yun Xingyi s muscles have stronger defense.At least until the problem of greater energy is solved, Li Shiming cannot equip Nezha with more powerful thermal weapons.
Hearing these familiar words in the world of cultivating immortals made him feel extremely bad.He gritted his teeth and said. Nowadays, the involution is very serious.
He knew about this formation. The formation s function was to transmit messages, scan the surrounding spiritual energy fluctuations, and be used for communication and warning.It is all rumors and the like. This can be regarded as satisfying the curiosity of the monks in the Qi Refining Stage about the elders.
Competitive. Hesitating in battle will result in losing the opportunity to enter the battle.Although the space here is isolated by spiritual beings with an insulating aura, he does not believe that this method can take him out of the Hundred Thousand Mountains.
Next to the spirit stone, three golden jade slips and one purple jade slip were suspended in the air, attracting his attention.The middle grade magic weapon Gatling is a real killer weapon.
They are waiting here, ready to watch the show. If Wang Chengjun comes back, it means that Li Yuanba, the true disciple, is finished.If one does not break through the Golden Core Stage, he will never be able to break through again.
Perhaps there are two branch spiritual veins heading towards Eagle Beak Island.It is estimated that even if all the sword cultivators in the Beishu continent are captured, there will not be this number.
Seeing the seven monks coming out, the Qi Refining monks from Beishu came forward without giving in at all.Elder Yin completely accepted this explanation without any doubt.
There is no need to worry about the problem of dizziness caused by spinning too much.You must know that he would not eat the middle grade Bigu Pill himself.
Li Shiming did not hesitate at all. He was convinced that his body s defense against high temperatures would not be harmed at least in a short period of time.He put the Light Body Technique in his hand and read several other books, Fire Bullet Technique , Object Expelling Technique , Sound Transmission Technique , and Freezing Technique.
Whatever he wanted to do, he put away the formation flag and moved on the valley wall towards the direction of Wei s station.He had been hit hard before, and now it was time to take revenge.
Xu Chuan, why are you hurt so badly Uncle Ma glanced at Xu Chuan and said while throwing out a bottle of pills.Besides, if you use a defensive weapon, you may suffer less damage.
In order to avoid getting Li Yuanba into big trouble, Li Shiming took his natal corpse into the computer room and used plastic surgery to modify his face.Under the control of his consciousness, it is no different from him in the outside world.
Otherwise, the world of immortal cultivation would not attach so much importance to the spiritual roots.If the genius monks are lucky enough, they may be able to go one step further and become a golden elixir monk.
Several of these monks also hid their faces, and even some of the stall owners hid their faces.He did not think he was qualified to ask about this matter.
What they were examining was the situation at one of the 128 nodes at the earthquake peak.This was specifically mentioned by Xu Chuan. He was not too confident about the channels here.
He canceled the Sword Escape, replaced it with the Flying Technique, and moved close to the ground towards the location where the sound was coming from.Physical labor such as spiritual mines is performed by monks.
This method of communication cannot see the other party s expression, and you always have to guess what the other party is thinking.He walked across the stone bridge and was about to return to his yard.
Li Shiming did not participate in the final auction of the super grade magic weapon.When he returns to the cave, through the ghost environment of the Netherworld Ghost Realm , the clone s injuries in the corpse refining state can be quickly recovered.
Originally, the mission this time was very simple. A monk who was doing things in the secular world would not be too strong.From Xiaosi Mo Yan, I learned that there is black stone in a nearby mountain.
But it s different when Elder Sheng takes charge. Elder Sheng has nothing to do with Li Shiming.Judging from the situation in the pit and surroundings, the power of this blow is extremely amazing, even exceeding the power of ordinary Qi refining in the later stages.
Moreover, when the clone practiced the Bing Xin Jade Thought Technique , the spiritual thoughts improved a little too fast, even exceeding the improvement speed of the main body s spiritual thoughts.After entering, there was a main hall with hundreds of stone tablets erected in it, which looked extremely strange.
While he was watching, the transparent flying boat stopped, and the five monks spread out to outflank him.Sword Intent, this is a sword cultivator He exclaimed.
That day, he was chased by the four clawed dragon demon.I can only hope that the true disciples can contain this half step Arhat Elder Jindan shook his head and sighed.
She had spent some time with Li Shiming, had seen Li Shiming s combat power, and knew the defense of Li Shiming s turtle shield.The monk of Wanfo Sect had a chance to break away from the battle.
He sent a message to Yu Yongan from Qianlong Trading Company to order a high grade metal sword.The rest are top grade magic tools. Even the top grade magic tools are of extremely high quality.
Mo Yan, you should study hard with Manager Zhang and be more stable Li Shiming turned to Mo Yan and confessed.This is the country s most important talent training channel.
No matter which sect, The Jindan elders are extremely mysterious.Monks have many invisibility techniques, but most of them are of little use to monks.
No matter whether Mr. Wang s bodyguard was out of helplessness or not, it was a fact that he was threatened with poison.His consciousness entered the computer room space. In the computer room space, there was a long pipe.
But it s different now. A piece of third grade metal is placed in front of him.This kind of fighting experience is not much, even the slow enemies have at least one or two explosive methods.
Look at your appearance, how can you be worthy of Fairy Yin You are a piece of garbage with three spiritual roots.What a joke, the Qi Refining monk is not a monk except his son.
If he wants the sect s foundation building monks to handle this matter, only if he dies in Zhongdu can the sect send the foundation building monks over.No matter whether it is the Seven Sects monks or the Northern Shu Qi Refining monks, they have no right to take the initiative to admit defeat.
The world of Immortal Cultivation in Northern Shu is called chaos , and the emergence of the Senluo Order is only a small aspect of it.He has experienced too much in the world of immortality and has long been accustomed to being on guard.
All the secret books here are from the Ten Spiritual Stones stall owner Zhang replied in a deep voice.Boom , the attack of the three powerful talismans only made a loud sound.
I like flowers and plants very much. Thank you, Second Senior Brother and Third Senior Brother Li Shiming smiled quickly.As for the spirit insects, under the intensive attacks of sword light and sword intent, each body was broken into several pieces.
After a soft introduction, she stood behind her father, Elder Yin.However, with Li Shiming s reminder, he quickly discovered something unusual.
Even if he did not use the Foundation Building Pill , there was a certain probability of successfully breaking through to the Foundation Building stage.Elder Yin did not participate in the battle. After the battle here, he notified the elders of each sect to come and look for the enemy.
It is a medium grade defensive weapon. I will charge you three hundred spirit stones The old monk nodded hurriedly.Weapons in the golden elixir stage are called magic weapons.
Today, I sold it again to Aoming Technology, which was backdoored by Xingyu Technology.Hua Yu was not at home, but working at Stars Capital.
the Shanghai Composite Index finally closed up 0. 35 at 2315.In the recent period, when the concept stocks of Galaxy Group have been hitting their daily limit continuously, the big financial sector has been very excited.
Now the investors who won the lottery for Xingyu Technology have already received text messages, and the stock trading circles are basically discussing it.After the market opened, Quantitative Capital quickly rushed to the price of 43.
As long as the market falls, the stock will rise, so it s okay to be bold and buy the bottom when the market falls.Last year, he earned more than 50 billion yuan from going long in the A share market.
Of course, this is also reflected in Xingyu Technology s operating costs, which are far higher than those of its competitors.Tian Jiayi nodded to himself thoughtfully, it is indeed a very good one to be linked to his personal medical credit rating.
They then use these profits to amortize R D costs, and products are soaring under Moore s Law.My colleagues are so envious Lingke TV will probably become the largest platform in the domestic online live broadcast field.
To put it more down to earth, at this time, you must develop steadily and not be reckless.The hacker in the video claimed that in order to reveal the truth and uphold justice, he hacked those social networking sites and claimed responsibility for the network intrusion.
The reason for the surge is the expectations brought about by the listing of a series of subsidiaries of Qunxing Capital.There was such a huge demand for computing power. and data needs However, this also made many people realize that Chen Yu was really spending real money to invest in technology development.
but was tricked into it by the good news. The index gapped down by 1.The exploration site in this video material is located in the upper reaches of the Yellow River Basin.
Since this company joined the Xingyu Technology supply chain system, the company s stock price is Rising steadily all the way, it is one of the few stocks in the two A share markets that bucked the trend and strengthened under the bear market environment.Throughout September, the market index fell into dog territory.
In fact, the same is true for animals in nature. when the living environment becomes harsh, animals will reduce the behavior of breeding offspring.Qunxing Capital is not hot money. Even if the hot money is doubled 10 million and earns 100 million, the 90 million earned can be thrown into a few steel shops in the market.
On Wednesday, September 25, the stock price of Quantitative Capital broke the limit for the first time, with the stock price falling to 203.5 billion from QunXing Capital. MiHoYo s post investment valuation was RMB 7 billion.
It actually told me the position of the exhaust valve, and also asked if I wanted to search for pictures
The man was surprised. The contact entries generated were so powerful.4 billion yuan. Moreover, the market is so strong that it holds high and the holders have little desire to stop profits.
This is the result of Fang Hong s massive investment in the semiconductor field by Star Capital over the years.Since the market pulled up a strong positive line last Friday, it has not continued to hit new highs this week, breaking through the high point of 2145 hit last Friday.
When the United States and the United States start to fight a technology war, Qualcomm will definitely lobby harder not to do so, and will try its best to help Xingyu Technology speak up.People who bought today were relieved after the shock in the market and expected to double the amount of meat, but now they were dumbfounded.
If he stepped into the room with his left foot first, he would be fired directly Or if you get the handle, send the person in directly to step on the sewing machine
The next morning, Fang Hong came to the Quantitative Capital headquarters again.256 billion yuan. What is this concept In the past year of 2011, Xincheng s total fiscal revenue for the year, excluding the tax paid by Qunxing Capital, was approximately 139 billion yuan.
71 at the end of the day. The stock price closed at 169.This is a counterattack. Foreign countries are now planning to stop selling our lithography machines.
There are quite a few people who seem to have been infused with inexplicable courage.Senior Brother Xiang is in the ninth stage of the True Law.
As for Yu Li s blow, since it was taken, there was no reason for it to miss.Two people from the east, two people from the west, Walk towards each other.
Come on. When you re done, just light the fire with the green flint and ignite it.This is the reason why after this person used the magic method of leaving the body with his gloves, his hands, which were only a few feet in size, were able to block nearly half of the damage in one fell swoop.
Qingquyu looked even more disbelieving and said Gui Taoist friend
are you saying that the ancestral domain will be unified and there will be no more chaos Which hero, who has not been born for thousands of years, can do such a thing Gui Wu Jiu smiled and said, You don t dare to be a hero who has not been born for thousands of years.
Everyone looked up and looked at each other, with astonishment on their faces.Now he can help temporarily, but it is beyond his imagination.
As soon as Jiang Minyi s punch came into contact, the complete attack power immediately turned into full repulsion power.With Xi Lerong s advanced realm, it is not difficult to catch the slightest abnormality.
The real reason is that Gui Wujiu, as this dome The true core is suddenly closely connected at this time, and external forces are naturally absorbed and endowed with spirituality.Xi Zhenzi and Mr. Li. Passing through the court mountain area of Dajue Mountain, a half decayed Yin Yang Cave was found by the last use of this cave, it collapsed and its traces were covered.
Because I don t like its greasy nature, I almost never eat it Fei Nan smiled lightly and said Why should you be surprised The sky is like this, the earth is like this, the sun is like this, and the moon is like this.However, Xi Lerong Yingyuan s scorching gaze fell on Xi Lerong without hesitation apart from not believing it, There seems to be another difficulty in letting go.
Gui Wujiu s journey to break through the realm, Ziwei Sword gained a lot, but no matter how much it was, it was not as much as the little blacksmith.Mo Tianqing said silently in his heart Bao Yue Kongyin, the Great Demon Lord.
One step wider, including those who have influence, know their way and hear their names, the scope is much wider roughly eight tenths of the important places in the Ziwei world that are rich in resources, outstanding people, and have good luck are included.Just now, Teng Ziliang was the first outstanding character but the person in front of him has greatly improved.
If you take the path of detailed analysis and detailed observation, you can only get a complete and slow glimpse of the whole picture, which cannot be reflected in your heart But if you add the best forbidden method to deduce the secret technique, there is still a chance.The words surrounding it, with writings the same size as those in normal books, are the secret scriptures of various clans in martial arts.
If it is expressed in words, no matter how voluminous the volume is and the words and sentences are carefully chosen, it will still be slightly distorted.I would not have thought that the display of boxing skills in this cultivation way is actually completely redundant.
Qin Menglin reached out and flicked it, and the image of the soul pearl flashed from his palm.The four of them turned to look at each other at the same time.
Liang Zhenjun was startled and said Yes. Just go to the Jiuzhuan Lingguang Palace.When they first mentioned it, Xian Dao and Ying Yuan asked about the situation of the two formations of the Dragon Clan and the Phoenix Clan, and said that they had a way to deal with it.
The length of time the Wait Array persists is the same.But Gui Wujiu had already made up his mind. Since I have been able to complete the path to enlightenment so far, I will definitely be able to complete this wonderful deed.
The shadow of the fist is in front, and the shadow of the toad is behind.Just one breath after Dongfang Wanqing said twenty breaths , Feng Qing entered the battle, and Long Yun was in the rear sweep formation.
There is only one flaw Taoist friend You Caixin does not yet have the combat power shown in your imagination.Xu Muyin frowned, but stepped back continuously. Just as the rabbit was rising and the falcon was falling, the situation of the battle seemed to be somewhat beyond his expectation.
Look at this baby image. It stands firm immediately after landing, and its big eyes are bright and lively.Xiandao and Yingyuan did not really want to escape and hide with them.
It can quickly analyze the pros and cons, check and balance the solution
While speaking, Qin Menglin s voice was erratic, and he returned to the way he had just reformed Mo Tianqing.Even if he doesn t have such shocking achievements today, this status alone is enough to be transcendent.
In other words, Gui Wujiu s wonderful idea of the combination of his own paddle wheel, the sword s paddle wheel, and one of the nine branch paddle wheels, the three paddle wheels , could not be completed for a while.
