Buy a plane?

"Mr. Yemelyanov, you probably don't know that our current J-5 is for the navy. If there is a problem and we want to solve it, the navy's funds will be used. If we want to purchase the Su-35,

The Navy won't want it, it can only be used by the Air Force. Our Air Force has no plans to update its equipment for the time being. Therefore, this solution is not feasible. Please think about it again, is there any other way?" Li Ming said very

He quickly reacted and explained like this.

"Yes, this is also a problem." Yemelyanov nodded: "We originally wanted to sell you the most advanced fighter jets in the country. Since you don't want it, then we will exchange it for a two-seat fighter-bomber.

How about the Su-30?”

Using the funds from the export of the Su-27, the Sukhoi Design Bureau has improved the two-seat fighter-bomber Su-30. There are many models of this aircraft. In history, ordinary people exported to the East, like the Su-30

Like the -27 two-seat aircraft, the one exported to Asan is taller. It not only has canards in the front, but also has vector nozzles in the back. Although it only has a lifespan of thirty hours, and although it is purely manual, Asan's heart is still

Satisfied, their Su-30's performance is much higher than Dongfang's!

Now, the Su-30 modified by the Sukhoi Design Bureau has a canard layout. They want to sell this aircraft to the East, so that they can continue to make a lot of money, and they are determined

The idea is to purely export this time and no longer be able to export production lines! To avoid being copied by the Orientals again.

There is nothing to say this time. The Navy also needs powerful fighter-bombers, especially fighter-bombers that require long range! The Su-30 is the best choice for the Navy!

"As long as your navy purchases forty Su-30s, we will solve the flight control problem for you. In fact, you have a simpler way, which is to purchase Su-33s directly from us." Ye Melyan

Nov was extremely happy.

In the past, when the Orientals copied the J-5, the Sukhoi Design Bureau was very angry. Yemelyanov once came angrily to criticize, but it was meaningless. The Orientals also threatened to replace all the parts.

, no longer relies on Sukhoi Design Bureau.

What now? If something goes wrong, don’t we have to come for help? Since we are asking for help, we have to agree to the Sukhoi Design Bureau’s request!

Yemelyanov has secured the Oriental. These forty orders are too precious for Damao. With this funding, the development of their new fighter jets will go more smoothly!

"Is there no other plan?"

"Of course not. If you just want to invite a few of our experts to help solve the problem, it is absolutely impossible." Yemelyanov firmly rejected the requests of several people: "You can only purchase fighter jets.

way to obtain technology export licenses, and you also know that we have been very lenient towards your copycat behavior."

Sun Chong had no other choice but to rush back to Huangdi Village. It was already late at night. He did not report to Wu Shengli, but first introduced these plans to Luo Yang and others.

"Isn't this old man too cruel?" After hearing this request, everyone exploded.

"Forty aircraft, each worth at least 50 million, which is two billion US dollars, or even more expensive. Where does the Navy get so much money?"

"That is, they are sure that we are not capable of solving the technology, so they ask us to spend huge sums of money to purchase it!"

They thought that they would be yelled at by Lao Maozi, but what they thought of was that Lao Maozi asked for tens of millions of dollars in technical consulting fees. Now this kind of request of billions of dollars is really too much!

Sun hurriedly spoke hesitantly: "Actually, our navy does need a batch of fighter-bombers. If the navy can purchase a batch, we can also survey and map the above technology, and it will be easier for us to develop a two-seat fighter-bomber ourselves."

"When the Navy wants to purchase, the Navy first has an intention, then goes through systematic demonstrations, and finally makes the purchase. Our Navy has to be proactive. Now we are passive in purchasing. If word gets out, won't the Navy be laughed at in the future?

?" Luo Yang said: "And what about us? Because of our incompetence, the Navy was forced to purchase a batch of fighter jets. Do we still have face? There is no need to report this news to the Navy! If the Navy is forced to do this

, I would rather resign than be angry with you!"

Luo Yang's attitude was very determined.

"If we don't do this, what can we do?" Sun hurriedly asked.

"Go to the 611 institute and ask them for help. Even if we are in competition, the 611 institute belongs to us and is our own! We will solve the problem ourselves and don't let the old fools take advantage of us!"

Sun hastily sighed: "Yes, this is the only way we can do it now. We are treating a dead horse as a live doctor. I hope the technical experts from the 611 Institute can find the cause of the malfunction for us."

The telegram asking for help was sent out in the middle of the night. On the evening of the next day, experts from the 611 Institute arrived at the base of Huangdi Village. The leader of the team was Yang Wei, the leader among the young people from the 611 Institute.

"Gong Yang, thank you for coming to help." Luo Yang greeted him: "We can no longer find the program bug. I hope you can help solve it."

"This aircraft is related to the Navy's aircraft carrier strength. We will definitely go all out. Now, please give us the flight control laws."

Hearing Yang Wei's words, the people present were a little embarrassed: "Gong Yang, we haven't fully understood the flight control laws yet."

What?

Yang Wei looked at everyone in surprise: "If you don't understand it thoroughly, how did you write the flight control software?"

"We just transplanted the flight control software from the prototype and made simple modifications."

Yang Wei frowned: "This is troublesome."

Americans do not touch the canard layout. On the one hand, it is because of the powerful engines, and on the other hand, the control of the canard layout is not linear. It is difficult to program the flight control system. The reason why the 611 can defeat the J-10 is because they have been fighting for N years.

They have already understood the flight control laws thoroughly. Later, they also conducted a lot of experiments on the Iron Bird test bed to try to be foolproof. The first flight of the J-10 was statically unstable, which fully demonstrated their technical skills.

However, other units cannot.

The Su-27 fighter jet is still too big for the 601 Research Institute. Although they have tried hard, they still cannot fully understand its flight control in a short time. The Navy is eager to get it, so it can only transplant the flight control directly.

Their fault investigation only looked for software defects, but did not connect them with the aerodynamic layout of the aircraft. Finding the cause of the fault in this way was like looking for a needle in a haystack.

"Gong Yang, what should we do now?" Sun hurriedly asked.

"Take its model and let's go to the wind tunnel."

What?

Everyone was immediately dumbfounded.

"Gong Yang, this is just a last minute move! Isn't it a little late for us to go to the wind tunnel now?"

"Yes, how long will this delay?"

Everyone is unwilling.

"Everyone, if you want to find out why the plane suddenly pitched up, you have to study the situation at the time. We don't need to use comprehensive wind tunnel data. We just need to blow the situation at the time and simulate it, and then compare it with the flight control data.

Find out what happened. Since you can't find the cause of the malfunction, then we are here and can't even find it!" Yang Wei explained.

Everyone was a little silent.

As soon as Yang Wei came, he proposed a completely different fault finding route than them. Moreover, if you think about it carefully, this route is really more thoughtful than them. There is no point in continuing to check the code. It is better to go to the wind tunnel.

Use a blow tunnel to identify the problem.

"Okay, then let's go to the wind tunnel!"

The location of the accident investigation was moved from Wasteland Village to Wind Tunnel.

If you want to develop aircraft, you must have a wind tunnel. Due to the Western blockade, the country was forced to build a large number of wind tunnels. In later generations, they even became the first in the world. Since the landing speed of aircraft carriers is not very fast, there is no need for them.

Special hypersonic wind tunnel, just go back to Shenyang.

In 1960, the country's first supersonic wind tunnel FL-1 was put into use at the Shenyang Aerodynamics Research Institute. Hundreds of products were tested numerous times in this wind tunnel.

Now, this wind tunnel once again welcomed a special guest. A scaled-down fighter model was put in and the situation at that time began to be simulated.

Yang Wei devoted himself wholeheartedly. Although he was not familiar with the Su-27 fighter, he was familiar with the fly-by-wire flight control. As long as he blew out the data and combined with the feedback from the fly-by-wire system, he could better find the cause of the failure.

Don't be anxious about this, he has enough patience.

However, Lao Maozi couldn't sit still.

"Mr. Li, how are your navy's considerations going?" Yemelyanov came to Li Ming's office again and asked him.

"The Navy is still having a meeting. After all, the request you made is too sudden. It is not easy to spend such a large sum of money. It must go through a lot of investigation and demonstration. It is very likely that we will need to send people to your place.

Investigation." Li Ming said: "Please don't be anxious."

"Isn't your navy anxious? All your J-15s have been grounded!" Yemelyanov said.

The outside world doesn't know about this kind of thing, but people in related industries can quickly find out the clues. As long as there are reconnaissance satellites scanning the sky, they will know.

"The Navy is also anxious." Li Ming said: "If you lower your requirements, for example, let us purchase two Su-35s first, I think the Navy will definitely approve it immediately."

Two planes? Of course two planes won’t work! If the Orientals only purchase two planes, there must be a conspiracy! It must be for surveying and mapping purposes!

"You can't eat hot tofu in a hurry, old friend, you are too anxious." At this moment, a voice came from outside.

Hearing the sound, Yemelyanov turned his head and saw a familiar figure.

"Mr. Qin?"

Qin Tao had completed his inspection of Shuangyang Factory and made various arrangements. After he came back, he heard that the accident investigation had not been completed yet, so he came over to join in the fun.

Wu Shengli and Qin Tao came together, but they had already gone to the wind tunnel. Qin Tao came alone and happened to hear the conversation inside.

"You are so anxious, do you plan to use this money as research and development funds to develop a new fighter jet?" Qin Tao said with a smile.

"Mr. Qin, I will not hide it in front of you. The plan you proposed last time is very good. It allows us to upgrade to a stealth machine in the simplest way. Therefore, we want to carry out such a transformation, but we must

Spend a lot of money on research and development.”

"Have you ever considered international cooperation?" Qin Tao continued, without giving the other party more time to think: "For example, if you cooperate with us, let us jointly complete the research and development and technology sharing of new fighter jets. By then,

We can equip it together, which is very popular in Europe."

Li Ming's eyes widened. Mr. Qin is so awesome. This suggestion is great!

601 is working hard to understand the technology of the Su-27. However, this world-advanced fighter jet far exceeds their research and development capabilities, so progress is slow. Now, if we cooperate with Damao, we can learn from it.

I gained a lot of useful experience.
