Chapter 1187: Can airliners also play stunts?

"Xiao, I regret it!" Eminem looked sad.
After everyone had left, Xiao Peng and the others returned to their scientific expedition life, as if nothing had happened--famous or something was the most annoying.
But Eminem is speechless to the extreme. Why is this happening? It's just that the boat is so boring! Just a little space, so few people, no matter who stays at sea for half a month will go crazy.
Xiao Peng took the fishing rod and sat on the side of the ship's gunwale and said unhurriedly, "Plain, my buddy. Look at how smart they are, and just leave. Look at you fool, I have to stay, I I advised you not to listen."
"There has been too much work during this time, plus this Grammy is so angry. So I want to find a place to relax, who would have thought this is the case." Eminem said bitterly.
Xiao Peng curiously asked, "Isn't this relaxation? What does relaxation look like in your eyes?"
Eminem replied without even thinking, "Beauty and wine."
Xiao Peng curled his lips: "Vulgar, so you can talk to Mengzi, you two have the same virtue!"
Yang Meng also pointed his ears: "Hey, it's not good people who speak ill of people behind their backs!"
Xiao Peng pointed to himself: "Do you think I look like a good person?"
"No!" Yang Meng didn't want to answer directly.
"Then what else are you asking?" Xiao Peng asked back.
Yang Meng sighed: "People are shameless, and the world is invincible."
Xiao Peng smiled slightly and changed the subject: "How about the Warriors of the Four Seas?"
Yang Meng shook his head after hearing this, "I'm still there to try, Huang Bin said it's luck. Maybe I'll send it back!"
After hearing this, Xiao Peng scolded angrily: "What's the matter, you have to change the big boat! This boat is not good for scientific research! Tell Huang Bin, do your best, anyway, this time I have found the baby! It is really impossible to go home! If you want to do well, you must first sharpen your tools. Our ship is not good for long-term scientific research projects! I want to transform this ship into a yacht when I go back, and then order a comprehensive scientific research ship. What do you think of the salvaged one? "
The ‘Warrior of the Four Seas’ broke down again, this time there was a problem with the power transmission. Huang Bin is a master mechanic, but the ‘Warrior of the Four Seas’ has indeed exceeded his abilities, so he feels helpless now. There must be professional personnel to solve the problem, but this seems to be too small.
However, there is no problem for them to go back now, because this time they came out really rewarded!
In addition to the polymetallic nodules, they found a large area of ​​rutile and monazite veins in the seaside ore!
Needless to say, rutile is high-purity titanium dioxide. The content of titanium dioxide in a piece of rutile is more than 95%. The metal titanium extracted from this thing is resistant to high temperature, low temperature and corrosion. However, this thing is very scarce in China. Only a few thousand tons, it is one of China's 14 strategic reserves that rely heavily on foreign resources! And China's annual demand has reached one million tons!
Although the price of this gadget is about the same as copper, it is in great demand, ranging from welding rods to high-grade titanium-white-powder and rocket fuel! Just for this stuff, it's totally worth mining here!
In addition to rutile, they also discovered monazite veins, which is more interesting.
In addition to the niobium used to make rockets and airplanes, the monazite also contains tantalum used in microcircuits, which is needed to make semiconductor chips. More importantly: there are uranium and thorium in it! With a certain amount of radioactivity! Although the amount is usually very low and there is no need for special protection, they found a monazite vein, which requires care-too much.
But in any case, the three discoveries of these two ore veins and polymetallic nodule mines this time have been considered overfulfilled. So no one said anything even after returning home.
Xiao Peng stared for a long time, but didn't get Yang Meng's answer. Looking back, Yang Meng looked up at the sky.
"What are you looking at? Can't you hear me talking to you?" Xiao Peng asked.
Yang Meng sighed and said, "This Star Tiao countryman just knows how to play!"
"Huh? Why do you say that?" Xiao Peng asked puzzledly.
Yang Meng said, "This is the first time I have seen this jetliner play aerobatics."
"Huh?" Xiao Peng was confused when he heard this. Who played aerobatics with jet airliners?
He followed Yang Meng's gaze, and as expected, a passenger plane flew by at high altitude.
It is no surprise to see an airplane over the Aleutian Islands.
Many people think that the plane from China to Star-Stripe Nation flew directly over the Pacific Ocean, but this is really not the case.
Take the capital to Los Angeles as an example. After taking off, Huaxia’s plane must first go all the way north, cross Mongolia, the Bear Country, and the Bering Strait to Alaska, fly into the Maple Leaf Country and then to Los Angeles.
This is because a lot of accidents occur during the flight of the aircraft. If it falls into the sea, it is difficult to rescue. Therefore, when flying, it is flying along the land. Even if it is over the ocean, it will not be too far from the land.
In addition, the airflow in the Pacific Ocean is very unstable and severe weather often occurs. As a fisherman, Xiao Peng deeply understands this. Flying in such a place is very dangerous.
Xiao Peng looked at the passenger plane in the sky, hey, he was really playing aerobatics as Yang Meng said.
Okay, it’s a bit exaggerated to say that it is playing aerobatics, but the attitude of the aircraft is really weird-first the nose dived down for a while, then the aircraft was pulled up for a while, then it dived for a while, and then again Pull up for a while. . . . . .
Yang Meng was at a loss: "What is this pilot buddy doing? Dislike too much fuel on the plane?"
Xiao Peng was also puzzled. After watching for a long time, he couldn't think of a reason.
Qian Congcong heard the excitement and ran out of the cabin to take a look: "I said, this plane won't fall, right?"
Xiao Peng gave him a white look: "Can you make a good judgment? The whole big crow's mouth!"
Qian Congcong shrugged and said: "Can I be blamed for this? Let me tell you, you know the Boeing 737MAX that fell from Ethiopian Airlines? Actually, I almost flew on that plane at the time. Thinking about it now, I am afraid."
Some time ago, a Boeing 737MAX crashed in Addis Ababa. No one survived on the plane. It was a brand new plane that was only four months old. There is also a Chinese the plane.
After the incident, people thought of the crash of a two-month-old Boeing 737MAX in Indonesia last year, only to discover that this was a terrifying model with fatal safety flaws, so countries around the world began to ground this model.
This is a tragedy in itself, but the incident has caused an uproar on Huaxia.com, and the reason for this is that the girl is rich at home.
So there are all kinds of sour words, and bad language such as ‘Send X a Thousand Miles to Return Your Life’ is endless.
Is this what people say? What is all special from the orphanage? No parent education?
In the eyes of these dirty people, as long as they are richer than me, they deserve to die! People with red eye disease can't say anything. Besides, let’s not talk about whether they have any foreign boyfriends. If they do, it’s your business?
In the eyes of some people (let's call them humans), this Chinese man seeks foreign women to win glory for the country, and Chinese women seek foreign men to make money for DIAO. Isn't that funny?
Yang Meng laughed after hearing this: "This is impossible. Boeing 737MAX are grounded worldwide. How can I still see that stuff now?"
Xiao Peng was taken aback, thought about it carefully, and looked up at the sky: "Fuck! You are really right. This is a Boeing 737MAX. Where is the Star Stripe Country? Boeing’s hometown! Other countries around the world have airplanes. Grounded, except for the Star Striped Nation! People say their planes are safe!"
Yang Meng asked puzzledly: "How do you know this is a Boeing 737MAX?"
"You can't see the two big engines? They are not in proportion!" Xiao Peng took a cold breath: "Mengzi, go get the binoculars, I rely on, why do I look more and more like something wrong? The MCAS system is sick again Up?"
The Boeing 737 has been in market for more than 50 years since its introduction. It is one of the most successful narrow-body civil airliners in the history of civil aviation in the world. It has developed 14 models.
The problem is the fourteenth model, Boeing 737MAX8.
Compared with the previous model, the biggest feature of Boeing 737MAX8 is the replacement of two LEAP-1B engines. This engine is 15% more fuel-efficient than the predecessor and has more horsepower! Make the MAX8 the farthest airplane in the Boeing 737 series.
But because of the replacement of this engine, it is easy to make the wings produce a greater angle of attack. To put it simply, the plane will raise its head when flying. If you raise your head too much, the plane will ‘lost speed’, which is what we call a stall.
In other words, the higher the nose of the aircraft is, the easier it is for the aircraft to lose lift and fall down!
Boeing’s designers didn’t take this into consideration, so they designed a maneuverability enhancement system, commonly known as MCAS. This system looks very high-end. To put it bluntly, it is similar to the autopilot system on a car. When the car is found to have deviated from the lane during driving, the autopilot system will correct the front of the car; while the MCAS system will force the nose of the aircraft down when the aircraft is raised too high!
But after all, this is an automatic control system, just like a car's automatic driving system. If the sensor works normally, then the automatic driving is normal, but what if the sensor is not faulty?
The same is true for the MCAS system, which has an angle of attack detector. If the detector fails, the MCAS system will push down the nose of the normally flying aircraft, and eventually an air disaster will occur.
After the Boeing 737MAX crashed in Indonesia, it passed the black box investigation for this reason. The Ethiopian Airlines crash should be similar.
So this aircraft is now grounded globally, and only the Stars and Stripes can see it.
Yang Meng looked up and suddenly turned over and slapped Qian Congcong on the head.
"It hurts, Mengzi, why are you hitting me?"
Yang Meng pointed to the sky: "You crow's mouth, you are right! There is a problem with this plane!"
