After inspecting the factory, the morning passed, and at noon, everyone went to the local customs and ate in the factory canteen.

"Mr. Lamour, what you have achieved is truly the envy of us." When eating, everyone originally sat separately, but Qin Feng deliberately chose the position next to Lamour, after all, everyone is a pilot, and there are a lot of common topics.

Qin Feng has a very important advantage over others, that is, Qin Feng can speak English, and there is no problem in communicating.

"Yes, we have to make ourselves strong because of the needs of the war, you guys are very sorry, it was not a low start, but it was a pity that it was abandoned for ten years."

Lamor still has a certain understanding of the East, and when he said this, Qin Feng was a little heavy, and the ten years were the era when all kinds of science and technology in the West were advancing by leaps and bounds, and the country lost precious time in vain.

In the sixties, domestic scientific research was not lagging behind, for example, in the most critical electronic system, its own transistors were not much later than the West, and the same was true for integrated circuits, but in those years, the Western world was developing rapidly, while its own side was standing still, so the gap came out.

The same is true for fighters, J-7, J-8, originally came out in the sixties, but it can't be used at all, the test flight work is intermittent, fortunately, it is back on track now, and there is a gap on its own, and it is also facing this gap, since there is, then we must take a big step and strive to catch up!

Don't complain about the past, take the vision of development, face the future, and be down-to-earth.

Wait, the other party is taking the topic astray!

Qin Feng came back to his senses and quickly pulled back the topic: "I think your Cub fighter has a good starting point, with the J79 engine, coupled with advanced avionics, it is even more like a tiger with wings, if this fixed canard wing is changed to a movable canard, plus fly-by-wire control, maybe, the performance is comparable to the Mirage 2000, if it is replaced with a third-generation turbofan engine, it will definitely be surpassed!" ”

Qin Feng's topic is not far from the aircraft, and it is the development of the aircraft, hearing Qin Feng's words, Ramour was also thoughtful, and finally, he also sighed: "Yes, you are right, in fact, we really had such a plan." ”

The LAVI fighter is not extremely secretive, and their project is destined to be an open project if it is to be carried out together with the United States, and at the same time, it is also to demonstrate their strong military research and development capabilities, so as to facilitate the sale of military products.

This is very similar to Dassault Systèmes.

Israel's historical origins determine the continuous war, in the war, they have trained their powerful troops, and they also have a first-class military industry, but it is definitely not possible to use it only for themselves, and the military industry must be sold if it wants to become a profitable project.

Needless to say, the latest LAVI fighters, just the current Cub fighters, are quite promising, they have already reached export agreements with several customers, and even helped a certain country improve their fighters.

As long as they give money, they can sell it, and the last time they sold the Monster Snake-3 missiles to China, there were political considerations, as well as economic interests, and they had to make money in order to feed their military-industrial complex.

So now, some of the previous stories of the LAVI fighter can also be told to Qin Feng, after all, these are all in the past, and it is not worth keeping secret.

Holding a knife in one hand and a fork in the other, while eating the medium-rare steak in front of him, Lamor talked to Qin Feng at the same time.

"We were planning the next model of the lion cub as early as when it was just finished, and we received a lot of encouragement based on the cub." Ramour said.

They were able to increase the aircraft's high angle of attack performance by 50 percent with just one canard wing, and the angle of attack range could easily reach 30 degrees.

Since then, Israel Aircraft Industries has been fascinated by the canard layout, and after further research, they decided to continue with their swept wings, with the canard and main wing overlapping design features.

It can be seen that the canard wing and the main wing overlap and the wing adopts a swept wing design with a relatively large aspect spread, which can compress the total length of the hull and the wing size to the maximum, and squeeze the canard layout and vortex lift interference ability to the limit, which is also a characteristic of the Jews.

In 1974, they had already decided to enter the specific development, and in the engine, the latest American F100 engine was replaced, but it was denied by the Air Force.

The Israeli Air Force has been able to buy the third-generation aircraft of the United States, and they have found that this Cub C2 scheme is seriously insufficient, and there is a considerable gap in the data of stable hovering and combat radius, so why doesn't the Air Force directly buy the F-16?

The Air Force wants to support the research and development of domestic military aircraft, but they also have to fight, and if the performance is insufficient, they will not compromise.

Later, they could only continue to improve, changing from single to double, and at the same time using the way of belly air intake, which is much better than the air intake on both sides of the lion cub, which is blown out of the wind tunnel.

At that time, it was planned to use two F404s, and later, after further development, it was finally determined that the Pratt-Whitney PW1120 engine would be used, and the overall layout of the fuselage was also determined.

"The research and development of fighters is really not easy, we have a saying, called slow work and meticulous work." Qin Feng said with a sigh, he knew that what Ramour introduced to himself was another advanced fighter that he was about to inspect, LAVI, and now, what he heard was the origin of this fighter, and Israel's aircraft experts have also been groping back and forth for about ten years, and Song Lao and them, how similar they are!

The failed Jian-9 project has been engaged in more than ten years, and the current No. 10 project has gone through several years, and now it has only begun to be formally developed.

Actually, there is another sentence that Qin Feng didn't say, which is called a good thing and a lot of grinding. The domestic research and development of fighters has gone through a difficult and tortuous road, and it is conceivable that there will be many difficulties and problems encountered in the future, but no matter what time it is, it will not give up, and if you persist, you will be able to go to the other side of victory!

The story of their fighter research and development, I have to take the time to tell Song Lao and them, which is also a harvest this time!
