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.

I have repeated my studies for two years and taken the postgraduate examination for two more years.For life. After hearing what Du Heng said, the eldest brother s face turned pale.
There was no embellishment or embellishment, just a very light narration of the whole process.I went to the hospital and was prescribed some anti inflammatory drugs and a bunch of vitamin 123 and so on, but it didn t work anyway.
He immediately called to Du Bing, Stop it, take your wife.That should be to thank him for saving his wife last night, but Du Heng glanced at his sister in law Zhang Sumei, Sister in law, why are you still collecting money Don t talk about the money, I don t even CBD Gummies Benefits Reviews: Weight Loss Wins for 7 American Office Workers want the carton of milk.
It only needs to have a department of traditional Chinese medicine, internal medicine, and surgery.Du Heng quickly asked, Has your father always eaten like this Absolutely.

Liao Quansheng glanced at Du Heng disdainfully, You have What a shame, I wanted to bring him here because he is down to earth and hard working, and he has a rough relationship with you.Why are you looking for me The Agricultural Technology Station is a piece of cake.
Let s just submit our needs and recruit new people.Can I go home in this situation Sister Zhang asked Du Heng a little worriedly.
It s actually quite interesting when you think about it.Xu Pinglin s mentality is difficult to describe. Simpli Health’s Breakthrough on Shark Tank: A Detailed Review She also became nervous when she heard Du Heng said that it would affect the fetus, Does Dr.
Du Heng, you don t have a bad face at all. How did you say this, one thousand a year Do you believe it I just said After we sign with you, we will be taken away for investigation.This is no problem, and he knows it but for patients with high blood pressure of 200, he has never seen this situation.
So, just tell the truth. Isn t that the purpose of you The Impact of Shark Tank Weight Loss Sisters’ Success Story on the Weight Loss Industry looking for me The elegant lady gently turned the tea cup at hand, Finally Let me ask you, do you promise that what you just said is the truth and there is no falsehood For example, when you proposed the treatment plan, she did not agree or reject it, and she did not raise any objection when taking the medicine.
Apart from being a little disgusted, there was no big loss, so he left it alone.After Du Heng finished speaking, he looked at the table in front of him.
He has never seen any stick injuries or knife The Incredible Benefits of Ashwagandha Leaves for Weight Loss and gun injuries, and he doesn t know what they are.Lu Zhongjiang was silent again, Then if we cooperate, What I m talking about is that even if you don t transport patients to us, what role will you play I didn t go into details, but it should be that you sit in the clinic in the morning and go to the ward in the Lifestyle Keto Gummy: Making Keto a Part of Your Daily Routine afternoon.
After cleaning his mouth and nasal cavity, he knew that Du Bing didn t have a car, so he didn t care about dirty hands.The colleague nodded in agreement. Similarly, he also knew the last sentence that Gong Daoyang did not say, that is, not a penny more.
You go in quickly. Huo Yinhua and the other three rushed in following the direction of Zhao Bin s finger, and then heard something inside There was the sound of Huo Yinhua arranging an examination.To say throw it Navigating the Journey: Emily Simpson Weight Loss 4 Strategies away is not an option. What if some big mouthed person goes outside to spread the word that Du Heng threw away or burned the pennant given by the patient Maybe something will happen.
The prescription I prescribed yesterday warms yang and eliminates yin, and steams the bladder to transform it into gas.Du Heng moved a small stool forward and sat down, then gently picked up his right hand to check his pulse.
In the front is the vehicle of the epidemic prevention team, and in the back is the ambulance pulling the patients.
