Qin Guan frowned and said, "you have aviation experts. You should know that re matching an engine is a complex and big project. If it is a turbofan engine with similar air flow, it is easy to match. If it is a turbojet engine, it will be troublesome."

Also coming with us was lafar, general manager of Davidson Aviation Industry Corporation. He was the person in charge of the Lavi project. It was after studying the jian-9 model of Han and hearing that the other party had improved the control rate and had an appropriate digital Telex system that he decided to give up the project of introducing the jian-14 and concentrate on building his own new duck layout fighter.

Now, when the other party raises such a question, it is also quite difficult for lafar.

Although things are in a hurry now, grassa and Rafael have not discussed in advance, and they know that now, if they want to reach this contract, they can only try their best to sell it to rainbow country.

Over the years, rainbow country has been subject to the world's arms embargo, while David country, backed by the eagle country, is not afraid of heaven and earth. It has been cooperating with rainbow country. Apart from others, rainbow country has a vast land. What weapons to experiment with and has a vast space. Apart from others, the ballistic missiles they want to experiment can only be launched from rainbow country, The two countries have also cooperated closely on nuclear weapons.

At present, the number of available fighters of the rainbow national air force is not large. They have 40 "phantom" F.1 in the 1970s, which are the latest aircraft.

For a medium-sized country, there are a lot of these fighters, but for a country with border war, once the aircraft are damaged, they will not be able to supplement. If these aircraft are shot down, they can only fight with the "phantom" III in the 1960s.

Due to the short range of "phantom" III, the engine and weapon equipment are old, the ammunition load is not good, and the war damage rate will be higher. Therefore, the rainbow national air force decided to upgrade the old "phantom" III first.

In this way, they found David, who purchased a batch of "phantom" III from chicken before the "Six Day War" in 1967, and ordered 50 "phantom" 5, that is, the improved version of "phantom" III.

Although the chicken country imposed an arms embargo after the war, the Davidian country stole the "phantom" III drawing and used it to make its own fighter.

With these aircraft, the kingdom of David finally transformed the lion cub fighter.

Rainbow national air force believes that they can make the same attempt. They purchased the production license of "phantom" III / F.1 and "atta" 9k-50 turbojet engine as early as the 1970s, and also have the corresponding drawings on hand.

The two sides hit it off and began to upgrade phantom 3. This is the "cheetah" project. Now this project is under planning, but rainbow country knows that this is a transition project after all. No matter how much improvement "phantom III" can compete with the real third-generation machine.

In other words, rainbow has the demand for three generations of state-owned aircraft. Historically, this is the "Carver" project, which is a light multipurpose fighter.

In the development of this fighter, the experts of Davidson are also closely involved. Of course, these are the later things. Now, for Davidson, they know the needs of rainbow country and that they want to develop the third-generation aircraft by themselves. Then, selling the j-14 to them is the best choice.

However, in terms of engines, they can only choose their own "atta" 9k-50, and it is impossible to buy new engines from any country.

Anyway, when the j-14 was sold, it was also without an engine. It happened that the two sides could match up, but this match was not easy.

In the development of fighter, the matching of inlet and engine is also a key point.

Although Qin Guan is a layman, Qin Guan is also clear. Now, of course, Qin Guan continues to be confused: "now, if you can't use the f404 engine, the rb199 in Europe is more appropriate and the changes are the least. As for others, it's really unexpected."

Qin Guan knew what kind of engine they were going to use, so now he wanted to exaggerate the difficulty. The kingdom of David could purchase from the kingdom of eagle, but it was absolutely impossible to use it for the kingdom of rainbow.

After all, if the "atta" 9k-50 engine is used, it can be explained that the aircraft is developed by rainbow country itself. After all, the appearance of the j-14 fighter is very similar to that of the F-16. Except for the different inlet ports, it is reasonable for other countries to make a similar one, but if the f404 engine is used, just investigate the source, Then the kingdom of David was completely exposed.

They wouldn't do such a thing.

"Our third party has only one turbojet engine on hand and the afterburner thrust is only 70 kn, so we may need to improve," lafar said.

The "atta" 9k-50 turbojet engine has a maximum military thrust of 49.2 kn and an afterburner of 70.6 kn, while the f404 engine has an afterburner thrust of 80 kn, so the power is not enough.

It seems that major changes are needed.

"We can increase the proportion of composite materials in the body to reduce the weight of the body," lafar said. "We can modify and match the inlet, which is enough."

Qin Guan frowned: "that's a big operation! Maybe it's a newly developed aircraft. No, forget it. Our business is not benevolence and righteousness. In the future, you'll have to equip j-14 yourself. Let's start negotiations again."

Qin Guan thought it was troublesome. Forget it. Let's stop doing it. It's almost like a newly developed aircraft. Let's not bother.

Qin Guan said so, and glassA hurriedly said, "we will bear the expenses incurred."

For David people, there is nothing that can not be solved with money. Unfortunately, money doesn't work here in Qin Guan. I have a money cemetery. Money is nothing to me. What I lack now is an excuse and a cover up.

"We're not short of money." Qin Guan said faintly. Just like last time, this sentence made glassA tick in his heart. He knew that the other party was asking for something again.

"Then how do you think you can change it with great effort?" glassA said, swallowing a mouthful of spit. It's not your own good things. There are few confidential things.

Then he saw the smile on Qin Guan's face and thought it must be impossible to keep it.

Sure enough, Qin Guan said, "such a big project must be exchanged with missile technology. The technology of the strange snake 3 missile, the Tammuz missile and the supporting production line you are developing are exported to us, and we can do a good job in the matching of fighters."

The food should be eaten mouthful by mouthful, and the food should be asked little by little. If the other party doesn't give it, let's talk about it later, or our party can show the new technology again. However, the composite armor technology alone will hang the other party's appetite, and the other party has to compromise.
