Babylonian Empire

When Tu Jida heard it, half a year was a bit tight, but if the funds are in place, the new fighter can be produced.

"That's fine too, but the modification has to be done in our company." Fred said.

After talking for a long time, I returned to the original topic?

"It is more appropriate to carry out the modification in our Chengdu Airlines." Tu Jida said: "The design and manufacture of the aircraft are all carried out in our company, and the modification is naturally also in our company."

"No, your company doesn't have our advanced equipment, so it's very troublesome to modify it," Kashin said.

The atmosphere became tense again. After all, the Yankee still wanted to get the plane over and study it himself.

"I have a proposal. The United States is too far away, and we have to cross the Pacific Ocean. To be honest, the equipment of Chengfei is a bit outdated. Why don't you go to our new aircraft factory to refit and test the flight!" Zhang Feng said: "Anyway, we Here, there is already a full set of testing equipment, which can meet the requirements of modification and testing, and, in this way, it can be done relatively secretly to avoid the hostility of certain countries."

Some of the countries Zhang Feng mentioned are naturally the big country in the north. If China improves its fighter jets with the help of the United States, the other party must be very upset.

When Fred heard it, although he was not in the United States, there are also a lot of engineers here, so he can fully understand this kind of fighter.

And Tu Keida feels that he can accept it, because this modification plan was originally proposed by His Excellency Qusay, and it was also His Excellency Qusay who helped to contact these avionics equipment. If the J-7 is modified like this, its combat effectiveness will still not be as good as that of the F-20. High, moreover, this fighter plane will be launched into the international market together with Iraq in the future. So far, the domestic air force still has no intention. All the funds for the modification are prepared by ourselves, so there is no need to worry about leaking secrets to Iraq.

The proposal was accepted by both parties, and it was passed.

"So, what kind of avionics equipment do you need?" Kashin asked.

"We need to use the 1553B data bus for the whole aircraft, and use your radar, cockpit display system, inertial navigation system and onboard computer installed on the F-20 fighter to form a brand new avionics system for our entire fighter," said Tu Kida. . "We plan to introduce [-] sets in advance."

These Freds have already learned from Zhang Feng in advance. The other party just wants to modify the avionics, and he also wants to sell the avionics. Anyway, this fighter is also exported, so there is no need to worry about too many technical leaks.

Fifty sets?When Fred heard this, he knew that it was really a big deal. He calculated it in his mind and said, "We have made a preliminary budget, which is about [-] million U.S. dollars."

Five hundred million U.S. dollars, a set is 1000 million U.S. dollars. You know, the F-20 is only 100 million U.S. dollars.

The Yankee's asking price is too harsh. You know, even the foreign exchange reserves of China as a whole don't even have [-] million US dollars.

"Mr. Fred." Zhang Feng spoke this time: "I hope you know that modifying the J-7 fighter is actually an international cooperation project. It is pushed to the international market, and the target of sales is also poorer countries like Asia, Africa and Latin America. There will be no competition for the sale of your fighters. However, if you add this kind of avionics, the cost will be too high, and it will not be the same at all. It won’t even be sold, let alone $[-] million, if that’s the case, there won’t be five dollars.”

Zhang Feng has already made it clear that you provide the technology for the modified avionics, but the asking price should not be too high, otherwise, I am not being taken advantage of, and I paid for the money myself. Besides, if you ask for such a high price, there is no Feasible, the plan can only fall through.

After finishing speaking, Zhang Feng looked at his watch and added: "I think the time is running out, you should fly back to the United States! Your company must be urgent."

Seeing the situation, Fred knew that he really wanted a lot. If he knew that Mr. Qusay was the one who paid the money in the end, he wouldn't raise the price so high: "This price is proposed by the company. The price, however, I will discuss it with the president when I go back this time, and the price should come down."

He can't say he is dead, so that both parties have room for maneuver, and, in the later stage, they can continue to increase funds!

"Up to 5000 million, including all modification costs, otherwise, I can go to Dassault to have a look." Zhang Feng said.

Fred was shocked in his heart, but his face remained calm, and he said: "After returning to the company, I will give you an answer as soon as possible."

5000 million US dollars, then, one is 300 million US dollars, and the profit is 150 million US dollars. Although the profit is not low, but this is a high-tech electronic technology, Fred feels that it is only within the acceptable minimum.

Watching Fred's passenger plane take off into the blue sky, Zhang Feng looked at the two Chinese people beside him, and said, "Tu Lao, Song Lao, that's all I can do. I hope your fighter jets, The test flight can be carried out as soon as possible, and I can invest 2000 million US dollars in advance for you, so it should be possible to manufacture a prototype, right?"

2000?Old Tu was overjoyed. With these 2000 million, four or five prototypes could be produced!

"No problem at all." Tu Lao said, "Your Excellency Qu Sai is really our great friend!"

"I have always attached great importance to the exchanges with your country, because your country will surely usher in a new take-off in the future!" Zhang Feng said.

"Next, I invite you to visit our aircraft production line. However, the factory is still in chaos, because some equipment is still being installed and debugged."

They were very excited to hear that they were invited to visit the production line, which was one of the purposes of their visit.

On the way to Zubair, Zhang Feng thought about his investment in Chengfei. Although his current funds are very tight, he still made this investment. However, after the successful development, the market potential is still very large. Neighboring Pakistan may have dozens or even hundreds of orders. At that time, this investment will bring real benefits.

Progress has been made in improving the nose, and Zhang Feng knows that it is time to explain the next plan to these experts.

"Tu Lao, in fact, the potential of the J-7 can be further tapped." Zhang Feng said. ?Sitting in Zhang Feng's business car, Tu Lao and Song Lao sat looking at Zhang Feng, but didn't understand for a moment. Is this person a natural talent?The improvement of the J-7 he mentioned is already a huge progress, and now he said, can the J-7 be transformed further?

"J-7 has been improved in this way, and its beyond-the-horizon capability is relatively strong, but its short-range combat capability is still not very strong. In fact, as long as the wings of the J-7 are improved, the combat effectiveness can be raised to another level." Zhang Feng said: "This method is to modify it into a double delta wing."

Double delta wings?Tukida asked: "Is it the double delta wing used by the Swedish SaabJ35 Dragon fighter jet?"

Zhang Feng shook his head first, then nodded: "Yes, but not entirely."

Chapter 3 Chapter Seven

To say that the father of the double delta wing is the Dragon fighter produced by the Swedish Saab company.

The so-called double delta wing means that the ordinary wing is a pointed triangle shape, and the wing sweep angle is a fixed value, while the double delta wing is more like the structure of two different triangles combined, such as the dragon style For fighter jets, the inner wing with a sweep angle of 80 degrees adopts a large-thickness wing-body fusion design, which provides ample space for fuel and main landing gear; the outer wing section is a small delta wing with a thin airfoil, and the leading edge is swept back The angle is 57 degrees, and the design of the outer wing section is conducive to improving the low-speed performance of the fighter and shortening the take-off and landing distance, while retaining the low-drag characteristics during high-speed flight; the vertical tail also adopts a swept back design.

Because the Dragon fighter is a tailless delta wing layout commonly used in the West, while the J-7 is a normal aerodynamic layout of wings and tails, the two are not the same.

"Our fighter plane also needs to be modified into a double delta wing shape, with an inner wing sweep angle of 57 degrees and an outer wing sweep angle of 42 degrees, and the addition of front and rear edge maneuverable flaps. After this improvement, this fighter will have Unrivaled close-range combat performance, even the American F-16 can't take advantage of it in close-range combat." Zhang Feng said while gesturing.

At the beginning, I didn't tell the other party about this improvement, not because Zhang Feng deliberately concealed it, but because Zhang Feng had to first determine whether the other party would really make up his mind to make improvements. As long as the other party made up his mind, then of course he would tell what he knew other side.

However, Zhang Feng knew that this knowledge was originally summed up by the other party a few years later. Historically, until the end of the 80s, Lu Yingyu, the chief designer of the J-7E and a student of Tu Jida, made a bold attempt to introduce Northwestern Polytechnical University sand Professor Bernan's research results creatively changed the original delta wing to double delta wing, and equipped with front and rear edge maneuverable flaps, which greatly improved the maneuverability of the aircraft.At the same time, a new type of high-power engine was installed, and the maneuverability of the J-7 was improved by a notch, far exceeding that of the MiG. In fact, Zhang Feng plagiarized their research results, but anyway, it was applied to the original object. On, just a few years late.

"Your Excellency Qu Sai, your knowledge is too rich." Song Wencong said, "We didn't expect that you are so knowledgeable, and we both feel ashamed."

"Where, where." Zhang Feng said: "Using this kind of wing structure, it needs to be redesigned, using the integral fuel tank of the wing. There's plenty of range."

The integral fuel tank of the wing refers to sealing the inner space of the wing to form a fuel tank structure, which can increase the fuel load by nearly 50.00%, increasing the voyage.

"If our fighter plane can be put into mass production in the end, then its performance will definitely be a qualitative leap above the original J-7." Tu Jida said.

"Yeah, should this fighter be given a new name?" Elder Song also said.

"This fighter jet can completely surpass the J-7. I think it would be better to call it Super Seven." Tu Lao said: "Our internal engineering code name should be called Super Seven."

Super seven?Sure enough, history is surprisingly similar!Zhang Feng thought about it, looked out the window, and said, "Our aircraft factory has arrived."

In the car behind, Kashin also got out of the car. Originally, the production line of his company had to go through strict approval before being visited. However, even if the agreement with these Chinese people was reached, they would also They came here for the installation and test flight of fighter jets. Moreover, this production line is already very backward compared to the United States. It was refitted from the F-5 production line, so Kashin did not raise any objections.

At this time, in the huge factory building, various equipment is being installed and debugged under the guidance of American technicians.

Although it is outdated equipment imported from the United States, it is still very impressive for Chinese visitors. The workshops that produce fighter jets in China at this time are still very backward.

For example, in the large workshop for producing aircraft girders, there is a large piece of equipment: CNC machine tools!

The main beam of the aircraft is the main stress-bearing part of the aircraft. It is equivalent to the spine girder of the human skeleton and plays a vital role in the flight of the aircraft. The uneven wall thickness of the girder will directly affect the flight performance of the aircraft. The processing quality of the girder will directly affect the flight performance of the aircraft. It affects the flight safety of the aircraft.For example, due to processing errors, the strength of some places is reduced. Then, in a fierce air battle, a large overload may cause the beam of the aircraft to break, and the fuselage will also be broken into two sections.

Regarding the production equipment of this set of girders, the negotiating team sent by Zhang Feng also spent a lot of effort. Northrop only provided finished girders at first, and did not want to provide processing equipment, because this kind of CNC machine tool is quite It is a complex processing machine, and it is also an export processing tool strictly controlled by the United States.

If you don't provide processing equipment, what is it to provide a production line!For this issue, the two sides negotiated for a long time, and finally reached an agreement: the United States will provide the forged girders, and the Iraqi side will carry out the cutting and processing.

The girder is first pressed into the desired shape by a large hydraulic press, and then cut. Therefore, although Northrop has generously promised to export the production line, it is still trying to hinder it in terms of specific problems.

The Iraqi side agreed, and Zhang Feng knew that obtaining a set of CNC machine tools meant that Iraq's processing level had greatly improved.
