A big country of aerospace with black technology

The prototype carrier-based aircraft T-10K-7 purchased from Ermao had returned to China by sea a few months ago.

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

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

If you are not careful, you will crash into the plane, fall on the deck, or rush out from the deck and fall into the sea.

Even Yingjiang, which has the most experience in aircraft carrier takeoff and landing, has experienced many landing failures and aircraft crashes and fatalities in these years.

Therefore, landing training is a very important thing before taking off and landing on an aircraft carrier.

"Is this our simulated aircraft carrier deck?"

Zhang Xingyang asked, looking at the slightly crude platform in front of him.

The rough cement floor is slightly raised, similar to the shape of a ski jump take-off deck, but this one also seems to be made of cement.

"Can this achieve the training effect?" After looking at it carefully, Zhang Xingyang was a little doubtful.

"According to the data we collected from various places, this is very close to the situation of aircraft carriers taking off and landing."

Yang Wei clasped his hands on his chest and looked at the "concrete 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 whether such a simulated aircraft carrier could successfully complete takeoff and landing.

"The aircraft carrier landing process is relatively complicated, and we are still exploring it."

Yang Wei's words were more tactful, but it can also be understood that there should be no landing training now.

It is also possible that you have practiced but failed.

Aircraft carrier landing is different from what many people have seen in games or movies and TV shows.

It has a very complex process.

The landing of a carrier-based aircraft does not involve flying directly from the tail of the aircraft carrier to the aircraft carrier based on the feeling. Doing so has a high probability of hitting the hangar or flying directly over it.

The landing procedure is a standard five-sided flight process.

On the first side of the flight, the carrier will fly past the right side of the aircraft carrier, release the landing hook when it is about 6 kilometers away from the aircraft carrier, and at the same time adjust the radar altimeter to an altitude of 125 meters.

During this process, the carrier-based aircraft must maintain an altitude of about 270 meters and a speed of 180 meters per second.

When a fighter jet flies by the side of an aircraft carrier, the pilot needs to visually observe the aircraft carrier deck to ensure that the deck is clear.

This operation has been used since World War II. Although communication equipment has been very developed now, pilots can know the situation on the aircraft carrier through communication equipment.

However, this kind of visual operation is still very necessary, because various unexpected situations may occur on the aircraft carrier.

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

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

Turn off the carrier aircraft's throttle, turn off altitude hold, press the bank to the left, and open the fighter's speed brake.

Because the speed brake is opened, the speed of the fighter jet will decrease. 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 fighter's speed brake will automatically retract.

Then the altitude of the fighter jet will be lowered. In the process, the altitude of the fighter jet will be reduced to about 400 degrees.

After trimming the aircraft, fly on the left side of the aircraft carrier until it is 1.5 kilometers from the rear of the aircraft carrier.

Make another turn and enter the fourth side. The slope of the fourth side is 27~30 degrees.

Note that the height is adjusted to 320 meters.

Entering the fifth side, during this process, you must always pay attention to whether you are aligned with the aircraft carrier runway.

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 safely on the deck.

However, generally speaking, as long as the landing hook can successfully hook the blocking rope, there is basically no problem.

"The pilots train very hard, but there are still several problems that trouble us, and we cannot solve these problems."

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

"What's the problem?" Zhang Xingyang looked away 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 subsequent things, so Zhang Xingyang also attaches great importance to it.

Apart from other things, Zhang Xingyang and the others wanted to build a space launch site in the South China Sea near the equator. Without a strong naval escort, it would be like hanging a piece of fat on someone else's doorstep.

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

"The main problem is the aircraft carrier arresting cable. At present, we have not found a manufacturer that can make qualified arresting cables."

Yang Wei sighed and said helplessly.

Blocking cables are a technology that only a few countries on this planet can afford.

The number of countries that can point out this technology tree is no more than one palm.

In fact, there are only three countries.

Although Gaul also has its own aircraft carrier, their aircraft carrier blocking cables are purchased from Eagle Sauce.

"We have considered importing some from Damao before, and we will first resolve the issue of availability."

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

"But Da Mao's technology in this area is still inherited from Mao Xiong. After inspection, it was found that it is actually a bit behind."

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

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

"What about Yingjiang?" Zhang Xingyang actually guessed Yingjiang's face, but he still couldn't help but ask.

After Yang Wei heard this, he smiled helplessly and said:

"They're killing people really well!"

"Do you know what price they offered us?"

Speaking of this, Yang Wei said angrily and funny:

"They want 10 million for a blocking rope!"

"Dollar!"

"It's just robbery!"

Zhang Xingyang was speechless after hearing this.

"Currently in the world, a single blockage can only cost 1.5 million US dollars!" Yang Wei thought about the arrogant faces of Yingjiang negotiators at that time and said:

"They actually charge us seven times the price!"

At that time, their negotiators still had a mentality that was like giving alms.

Many people involved in the negotiations were so angry that they almost broke down due to high blood pressure.

"An aircraft carrier requires at least four arresting cables. This means that if we import the arresting cables from them, this alone will cost more than 300 million!!"

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

"A blocking rope can only be used a hundred times at most, and a single aircraft carrier deployment requires hundreds of sorties at least."

When Yang Wei said this, he felt a little bad.

It can be seen that the negotiators of Yingjiang were very angry before this.

“If we really accept their plan, the cost of dispatching our aircraft carrier will be too high.

And it's easy to be manipulated by them. "

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

"Dean Zhang, I beg you, can you develop a qualified aircraft carrier arresting cable as soon as possible?!"

Zhang Xingyang was also somewhat infected by his emotions.

"Don't worry, we will do our best to complete the development of the aircraft carrier arresting cable!"

The difficulty in the development of aircraft carrier arresting ropes is mainly the material and processing and manufacturing issues of the rope itself.

The Materials Experiment Center of the Rocket Academy is now one of the best in materials science in the world.

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

Zhang Xingyang patted Yang Wei's shoulder excitedly 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 flying experimental J-15s, trying to conduct aircraft carrier flight training.

We are getting closer to actually flying on an aircraft carrier!

Today, these pilots who are undergoing difficult training on land will one day fly over the vast seas of the motherland.

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

"Our most important work recently is to complete the development of aircraft carrier arresting cables."

Zhang Xingyang didn't waste any time and directly announced his plan to block the development of cable.

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

"Brother Xingyang, none of us have ever been exposed to research in this area."

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

As Zhang Xingyang spoke, he distributed some pamphlets to everyone.

"Most of what is above is the current research data on aircraft carrier arresting cables from various countries."

After getting the information, most people started reading it.

Then they discovered that the information was too detailed.

They even have the material formula and production process for their blocking ropes.

The researcher who read it the fastest asked with some confusion after reading it: "Haven't these already been studied and understood?"

"What else do we need to do?"

Those researchers who had not finished reading but had already noticed something was wrong looked at Zhang Xingyang with doubts on their faces and asked.

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

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

"How long do you need?"

After asking this question, everyone present started to communicate.

After discussing for a few minutes, everyone came to a general conclusion:

"In a month, there should be no problem."

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

Zhang Xingyang said directly without any hesitation:

"In a month, I hope to see the finished product."

After assigning everyone their respective work contents, Zhang Xingyang left the laboratory without saying anything else.

Only the researchers were left with questions on their heads.

However, after a while, everyone began to start their own research work according to Zhang Xingyang's plan.

Zhang Xingyang did not go about other things after leaving as they thought.

On the contrary, he began the work of making high-strength blocking ropes by himself.

In later generations, there was actually no technical difficulty in blocking the steel cables.

It can be purchased directly from large steel cable manufacturing companies.

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

What is really difficult is the other things that come with the blocking rope.

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

Below him, there are many mechanical, hydraulic, and electronic equipment.

It is these devices that ensure that a single rope on the arresting cable can pull a fighter jet that weighs dozens of tons and is as fast as a train.

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

Zhang Xingyang is currently developing an arresting cable device with a hydraulic device and an accumulator.

Able to realize automatic adjustment of aircraft landing speed and weight.

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

Although, in the early stages of the aircraft carrier, there may not be such a variety of fighter jets landing on the aircraft carrier.

However, out of precautionary considerations, Zhang Xingyang designed the arresting cable according to the landing requirements of various fighter jets.

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

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

After testing, this steel cable, which is no thicker than a baby's arm, can withstand the impact of 20 tons of weight at 150 meters per second.

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

"The product is unqualified." Zhang Xingyang said helplessly.

In fact, this does not mean that such a blocking rope cannot be used, but it will cause great risks.

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

The researchers present didn't think anything was wrong.

After all, it has only been half a month, and it is considered good to be able to achieve this level.

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

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

It has withstood the impact of 40 tons of weight at 180 meters per second.

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

"But there is room for improvement."

So, the researchers started improvement work again.

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

This time, the steel cable withstood the terrifying impact of a 60-ton weight at 210 meters per second.

This kind of impact actually exceeds the impact of a heavy carrier-based aircraft when it lands on the ship.

Basically, only when a fighter jet reaches supersonic speed can it achieve such a terrifying impact!

Zhang Xingyang closed the record book in his hand:

"Conformity!"

"It's perfect!" (End of chapter)
