The prototype of the carrier-based aircraft, the T-10K-7, which was bought from Ermao, had already returned to the country by sea a few months ago.

Along with this, there is also a large amount of information on the landing training of aircraft carriers.

The most dangerous moment for a carrier-based aircraft to be on an aircraft carrier is when it lands.

If you are not careful, you will collide with the plane, or fall on the deck, or rush out of the deck and fall into the sea.

Even Eagle Sauce, which has the most experience in aircraft carrier take-off and landing, has had many cases of landing failures and aircraft crashes and deaths over the years.

Therefore, landing training is a very important thing before the aircraft carrier takes off and lands.

"Is this our mock aircraft carrier deck?"

Zhang Xingyang looked at the slightly shabby platform in front of him and asked.

The rough concrete floor is slightly upturned, similar to the shape of a glide take-off deck, but this one seems to be made of concrete.

"Will this have a training effect?" After taking a closer look, Zhang Xingyang was a little skeptical.

"According to the information we have collected from various places, this is very close to the take-off and landing of aircraft carriers."

Yang Wei clasped his hands in front of his chest and looked at the "cement aircraft carrier" in front of him and said.

"Okay, have you done landing training now?"

Zhang Xingyang reluctantly accepted Yang Wei's statement, but he was still a little curious about whether such a simulated aircraft carrier could successfully complete takeoff and landing.

"The aircraft carrier landing process is complicated, and we are still figuring it out."

Yang Wei's words were more tactful, but he could also know that there should be no landing training now.

It is also possible that they practiced but did not succeed.

The landing of an aircraft carrier is different from what many people see in games or film and television dramas.

It has a very complex set of processes.

The landing of carrier-based aircraft does not fly directly from the tail of the aircraft carrier to the aircraft carrier by feeling, and there is a high probability that it will hit the hangar or fly directly over.

The landing procedure is a standard pentalateral flight process.

On the first side, the carrier will fly behind the right side of the aircraft carrier and release the hook when it is about 6 kilometers away from the aircraft carrier, while adjusting the radar altimeter to an altitude of 125 meters.

In this process, the carrier-based aircraft has to maintain an altitude of about 270 meters while maintaining a speed of 180 meters per second.

When a fighter flies over the side of an aircraft carrier, the pilot needs to visually observe the deck of the aircraft carrier and make sure that the deck is clear.

This operation has been applied since World War II, although the communication equipment has been very developed today, and pilots can know the situation on the aircraft carrier through the communication equipment.

However, this visual operation is still very necessary, because there may be various unexpected situations on the aircraft carrier.

If there are aircraft, vehicles or people on deck, landing is dangerous not only for them, but also for the carrier-based aircraft that want to land.

After visually seeing that the deck is clear, when flying 2 to 3 kilometers over the bow of the aircraft carrier, prepare to turn the second side.

Fold out the throttle of the carrier-based aircraft, close the altitude hold, press the slope to the left, and open the jet brake of the fighter.

Because the airbrake opens, the speed of the fighter will decrease, and when the speed of the carrier-based aircraft decreases to 130 meters per second, the landing gear of the carrier-based aircraft will be lowered.

At this time, the jet brake of the fighter will automatically retract.

The height of the fighter is then lowered, and in the process, the height of the fighter will be reduced to about 400 degrees.

After trimming the aircraft, fly 1.5 km from the left side of the aircraft carrier to the tail of the aircraft carrier.

Make another turn into the fourth side, and the fourth side slope is 27~30 degrees.

Note that the height is adjusted to 320 meters.

When entering the fifth side, in the process, you must always pay attention to whether you are aiming at the runway of the aircraft carrier.

This is also the most dangerous and difficult process in the entire landing process.

You need to land this big guy weighing dozens of tons on the deck safely.

However, in general, as long as the landing hook can successfully hook the arresting line, there is basically no problem.

"The pilots train very hard, but there are several problems that are bothering us, and we can't solve them."

Yang Wei turned his head at this time, looked at Zhang Xingyang and said.

"What's the problem?" Zhang Xingyang withdrew his gaze from the cement aircraft carrier:

"As long as we can solve it for you, we will solve it for you as soon as possible."

The aircraft carrier project is related to many follow-up things, so Zhang Xingyang also attaches great importance to it.

Not to mention, Zhang Xingyang wants to build a space launch site in the South China Sea near the equatorial sea, and without a strong naval escort, it is equivalent to hanging a piece of fat meat at the door of someone else's house.

Therefore, Zhang Xingyang's desire for the navy to become strong as soon as possible is actually much stronger than most people.

"The main problem is the aircraft carrier blocking cable, and at present, we have not found a manufacturer that can make a qualified blocking cable."

After Yang Wei sighed, he said helplessly.

The blocking rope is a technology that only a few countries on the planet can afford to play.

There are no more than a handful of countries that can name this tech tree.

In fact, there are only three countries.

Although Gaul also had its own aircraft carriers, their aircraft carrier blocking ropes were purchased from Eagle Sauce.

"We had previously considered importing some from Da Mao and solving the problem of having it first."

Yang Wei talked about their difficulties in finding the aircraft carrier blocking cable:

"But Da Mao's technology in this area is still inherited from the old Mao Xiong, and after the investigation, I found that it is really a little backward."

Since the disintegration of Mao Xiong, Da Mao has basically stagnated in aircraft carrier technology, and most of the funds of the navy have been invested in strategic nuclear submarines.

Thirty years after the separation, their aircraft carriers were basically completely scrapped, and the tonnage of surface ships was not comparable to the strength of a domestic fleet.

"What about Eagle Sauce?" Zhang Xingyang actually guessed the face of Eagle Sauce a little, but he still couldn't help but ask.

After Yang Wei heard this, he smiled helplessly and said with a wry smile:

"They're so good at killing people!"

"Do you know what kind of price they offered us?"

Speaking of this, Yang Wei said angrily and funny:

"A blocking rope, they want 10 million!"

"Dollars!"

"It's a robbery!"

Zhang Xingyang was also a little speechless after hearing it.

"At present, in the international community, a blocking rope is only 1.5 million US dollars!" Yang Wei thought about the arrogant face of the Eagle Sauce negotiator at that time and said:

"They even demanded seven times the price from us!"

At that time, their negotiators were still in a state of mind as if they were giving alms.

Many people who participated in the negotiation were so angry that they almost broke their bodies because of high blood pressure.

"An aircraft carrier needs at least four blocking cables, which means that if we import blocking cables from them, this alone will cost more than 300 million!!"

Not only that, the blocking cable is not a one-time expense, it has a service life.

"A blocking cable can be used at most about 100 times, and an aircraft carrier will fly hundreds of sorties, let alone a few hundred sorties."

When Yang Wei said this, the whole person was a little bad.

It can be seen that the negotiators who were Yingchan were very angry before this.

"If we really accept their plan, the cost of our aircraft carrier sortie is too great.

And it's easy to be picked up by them. ”

Yang Wei said, grabbed Zhang Xingyang's hand and said:

"Dean Zhang, I implore you to be able to develop a qualified aircraft carrier arrestor as soon as possible?!"

Zhang Xingyang was also somewhat infected by his emotions.

"Rest assured, we will do our best to complete the development of the aircraft carrier arresting cable!"

The difficulty in the research and development of the aircraft carrier arresting cable is mainly the material and processing and manufacturing problems of the rope itself.

The Material Experiment Center of the Rocket Research Institute is now one of the best in the world in terms of material science.

"Although we have not carried out similar development work before, in order to allow you to use a qualified blocking cable, I promise to complete the development work in the shortest possible time!"

Zhang Xingyang patted Yang Wei's shoulder with some excitement and said.

Before leaving, Zhang Xingyang took one last look at the cement aircraft carrier not far from him.

In the sky, there are pilots piloting the experimental J-15 and trying to conduct aircraft carrier flight training.

It's getting closer and closer to a real flight on an aircraft carrier!

Today, these pilots, who are training land, will one day gallop on the vast sea area of the motherland.

Back at the research institute, Zhang Xingyang found researchers from the materials laboratory in the research institute who did not have important research tasks.

"Recently, our most important work is to complete the development of the aircraft carrier arresting cable."

Zhang Xingyang did not waste a little time, and directly announced the plan to block the development of Suo.

Most of the researchers present looked at each other, a little confused.

"Brother Xingyang, none of us have been exposed to this research content."

"That's not a problem, you can take a look at this first."

Zhang Xingyang said as he handed out some pamphlets to everyone.

"Most of the above are the current research data of various countries on aircraft carrier blocking cables."

After getting the information, most people looked through it.

Later, they found out that the information was too detailed.

Even their blocking cable material recipe and production process are there.

The researcher who saw it the fastest, after reading it, asked with some puzzlement, "Haven't these already been studied?" ”

"What else do you need us for?"

Those researchers who hadn't finished reading it, but had already seen that something was wrong, also looked at Zhang Xingyang with puzzled faces at this time and asked.

"I need everyone to work together to reproduce them."

Zhang Xingyang did not answer the question of the information, but asked everyone:

"How long will it take you?"

After asking this sentence, everyone present began to communicate.

After a few minutes of discussion, everyone came to a general conclusion:

"A month's time, there should be no problem."

"Okay, I'll give you a month."

Zhang Xingyang did not hesitate and said directly:

"In a month's time, I hope to be able to see the finished product."

After assigning everyone's respective work content, Zhang Xingyang didn't say anything and left the laboratory directly.

Only the researchers were left, and their heads were full of question marks.

However, after a while, everyone began to follow Zhang Xingyang's plan and started their own research work.

Zhang Xingyang didn't go to other things after leaving as they thought.

Instead, he began to work alone to make high-strength blocking cables.

In later generations, in fact, there was no technical difficulty in blocking the steel cable.

Among the large steel cable manufacturing companies, it can be purchased directly.

It is not impossible for ordinary people to buy steel cables for aircraft carriers.

What is really difficult is to block the other things that are supporting the cable.

Because the arresting line is not just a rope tied to an aircraft carrier.

Beneath him, there are many mechanical, hydraulic, and electronic devices.

It is these devices that ensure that a single rope of the blocking cable can pull a fighter jet weighing dozens of tons and a speed comparable to that of a bullet train.

Without these devices, the interception success rate and safety of the blocking cable will be greatly reduced.

What Zhang Xingyang is now developing is a blocking cable device with hydraulics and accumulators.

It can realize the automatic adjustment of the landing speed and weight of the aircraft.

It can adapt to the landing needs of fighters, early warning aircraft, and electronic countermeasures aircraft of different types and weights.

Although, at the initial stage of the aircraft carrier, it is possible that such a wide range of fighters will land on the aircraft carrier.

However, out of the consideration of taking precautions, Zhang Xingyang still designed the blocking cable according to the landing needs of a variety of fighters.

Half a month later, the first aircraft carrier arresting cable was born in the workshop of the experimental center.

This blocking cable is stranded with multiple steel cables, and there is a high-strength steel cable as the core in the center, which can greatly improve the strength of the steel cable.

In the test, this steel cable, which is less than the thickness of a baby's arm, can withstand the impact force of 20 tons of weight for 150 meters per second.

For intercepting light carrier-based aircraft, it is already relatively qualified.

"The product is not up to standard." Zhang Xingyang said helplessly.

In fact, this kind of blocking cable does not mean that it cannot be used, but there will be great risks.

For some heavy carrier-based aircraft, it is still a little too vulnerable.

The researchers present didn't feel anything.

After all, it's only been half a month, and it's good to be able to do it to this extent.

A week later, the second batch of completed steel cables appeared in the test center.

This time, the performance of the steel cable has risen a lot compared to the first time.

Withstood the impact of 40 tons of weight and 180 meters per second.

"The product is qualified." Zhang Xingyang said with a smile:

"But there's room for improvement."

So, the researchers began to work on improvements.

Four days later, the third batch of steel cables was freshly baked.

This time, the steel cable withstood the terrifying impact of 60 tons of weight 210 meters per second.

Such an impact force actually exceeds the impact force of a heavy carrier-based aircraft when it lands on a ship.

Basically, only a fighter can reach such a terrifying impact when it reaches a supersonic state!

Zhang Xingyang closed the notebook in his hand:

"The product is qualified!"

"Perfect!" (End of chapter)
