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.

He carefully used his spiritual consciousness to search the mustard seed ring, and soon he found a green gem.The clone Li Yuanba is in Zhongzhou, but to enter that treasure, you need the jade token in his hand as the key.
One year passed in the blink of an eye. Li Yuanba ended his retreat.Not to mention the items on the second floor, even the items on the first floor can be clearly seen.

As a result, Qin Feng arbitrarily believed that the Fan family had cooperated with the Yangguo people based on a few words, which was Candid and Honest: Tru Bio Keto Gummies Reviews Shared by Those Who Tried Them
really a false accusation.These Yangguo people were wearing kimonos and had a sword at their waist.
Chen Chuqing would not rely on others because of her predicament, but now she was dependent on Ye Rufeng because of her own predicament, and even chose to stay after being humiliated by Ye Rufeng.Haha. The other side smiled coldly, ending the topic.
So she was dizzy and signed several pages of paper with her name.I suddenly felt that you are more interesting than Chu Tiankuo.
Yanzi reacted the fastest and quickly took the lead What, everyone has worked hard tonight, let s go up and rest first, don t live up to General Yehuang s kindness Others also hurried down the steps when they got there, and everyone said that they were If you feel sleepy, go upstairs quickly.As for Zou Qi, he can t even talk about practicing skills.
I have to suppress the news. Yes. Qin Feng nodded I ll leave this to you, Du Tianhu will take care of it.After saying hello to Xu Shaoqin, Qin Feng left Splashing Star Hall first.
With the instructions of others, I must have gained a lot of benefits.He drove himself, taking Miao Jin and Tang Kexin with him, and stopped in front of the Qin family.
He looks ordinary and has no special features. The Panlong Palace was famous back then, but this is the only one here today Isn t that right, Tang Can Chu Tiankuo, the Dragon Lord of Understanding the Benefits and Uses of CBD Gummy Bears for Overall Well-being
Tang s Panlong Palace, hold up the show On the Panlong Palace side, Qin Feng brought four people with him when he entered.
Nonsense Qiu Luoluo sneered at Qin Feng s argument.If you know you can t afford to go, it s better than being kicked out and embarrassed when you get there.
Then, Qin Feng was seen grabbing Yuan Shan s neck and lifting him up from the ground.Compared to the calmness of the middle aged man, Dou Longyang and the others on the other side were more nervous.
Old Mrs. Ye glanced at it. With him, our Ye family s industry can hardly get involved, and the gray industry underground in Shencheng is even more out of reach.If you kill him, won t you be afraid that Long Daoling will kill all the disciples of our mountain sect Uncle Liu s face was ashen.
Okay, okay, stop flattering, people are here. While speaking, Qin Feng and others had already arrived at the entrance of Splashing Star Hall.
Chen Xian was surprised that Su Ye had not used it before.However, Luo Qiu has lived in Nanshan in Tianjing City all year round, so he has the theory of Tiannan Sage.
The book saint s daughter can t be beaten, so why are they just having fun Slip away, slip away No one was playing, so Su Ye gave Chen Xian nine yuan with a handful of puzzle cards, and then asked Luo Qingqing How many lantern riddles did you guess Luo Qingqing smiled and said, Not as good as Brother Experience the Revolutionary Power of K3 Keto Gummies: A Game-Changing Solution for Your Keto Journe
Su, who only guessed five correctly.
You, Luo Qingqing, are bold and affectionate by nature.However, I can provide several more elixirs for refining.

Yes, there is another way Su Ye had noticed a problem before.In addition, the second job Su Ye thought of was working in a drug store.
As a rule maker, you must be willing to abide by the rules so that others can be convinced and willing to abide by the rules, and at the same time believe that they Is It OK to Take CBD Gummies Daily? Benefits, Dosage, and Safety

The demon is just a servant, a kid who obeys orders.Among them, there are more than one hand can count that can be passed down through the ages, are familiar to people, and can be recited by heart.
I can t hold it back anymore. After all, after living a good life, who wants to live a poor life again.He said that he led the team out of the mountain, and he was the one who sent people into Huyue Gorge to pick up black sand crystals.
How can you do it without some cover up Of course, the status of a scribe is also very important.You kid can t trust me. In the mountain cabin, Lu Feiyu was lying on a rocking chair, sipping tea and said, Can I still rely on you Counting the lantern festival, you now have four egret seals.

Chu. But the most important thing is that there will be a big storm in the upcoming martial arts conference, and he must have enough strength to deal with it as soon as possible.Although Qin Feng exposed it, Meng Changfeng did not panic at all.
The two sides haven t met yet, but the expressions of Han Qiusheng and Du Bangyan have dropped to freezing point.The martial alliance has close contacts, and I m afraid there will be a lot of trouble in the future.
But
An Jiuxiao pondered for a moment and sighed softly What is the reason for his burst of power this time It s hard to say whether to vent the last of his strength to save his life, or to truly refining the strength gained this time without breaking or establishing
Chen Chuqing breathed a sigh of relief when An Jiuxiao said that Qin Feng s life was not in danger.
They came to Dragon City Why Qin Feng asked curiously.Although dozens of people died that day, there are still remnants left in Shencheng.
Tang, who had never wanted to see Qin Feng, rarely smiled when she heard this, although it was just a faint smile.And following her was Xu Yue er who had just come off the court.
She said that she should believe Qin Feng, and she also believed that if Qin Herbal Harmony CBD Gummies: Review the Supplement Ingredient Benefits
Feng could speak, he would never let them go in and take risks.His men pulled the black cloth off the man s face, and a face full of tears and despair appeared in front of Qin Feng.
The reason why it is a secret is that this task was handed down directly by Mr.She is still working as a dishwasher in our restaurant.
Hearing that Chu Huaijiang actually said such treacherous words, the man behind Mu Miye The helper suddenly frowned.However, during the heyday of Panlong Palace, he didn t even know what the world was like.
