In China, the main weapon of air combat is still machine guns, and the aiming of machine guns is very complicated.

All fighters use dynamic halo sights, and pilots must understand the principle and master the steps: "follow well", "wrap well", and "stabilize well".

These operations are quite cumbersome, and in air-gun combat, as the speed of the aircraft continues to increase, it is necessary to chase the attack, and it is possible to hit within 500 meters.

No one in China has delved into the new technology of machine guns, after all, for machine guns, which are mechanical weapons with mature principles and simple structures, there is not much room for performance improvement and no great value; There is limited room for the projectile to increase its lethality, and it is unlikely that the dispersion will be substantially improved, and the effective range is limited by muzzle velocity and dispersion, and it is even less likely to increase far.

The goal of all fighter designers is to put on the missile, few people know that the cannon is actually developing, although the cannon itself has no potential for development, but the comprehensive application of radar, head-up display, electronic computer, so that its aiming method has achieved a revolutionary breakthrough.

Qin Feng's favorite thing is to read foreign aviation frontier newspapers and magazines, all kinds of materials, he has long known about this advanced cannon aiming system developed by the West.

This has to start in 1969, when the US Air Force personnel, who could not tolerate the active halo sight, put forward a request to the United States to develop a new principle cannon aiming method based on the experience of the Vietnam War. The sight of the new technology is applied to develop a new type of hot-wire aiming based on the electronic computer, head-up display and radar.

The hotline aiming takes the electronic computer as the core, and counts the data of the fighter in various states, including altitude, speed, angle of attack, sideslip angle, pitch, slope, warhead muzzle velocity, ballistic coefficient and other conditions, that is, the impact point of each shell launched relative to the position of the machine is calculated, and connected into a dynamic curve, which is displayed on the heads-up display; The starting point of the hot line is a cross, which represents the muzzle, while the farthest point corresponds to the maximum range in the design of the sight.

When he first saw this kind of aiming system in the journal, Qin Feng was already full of yearning.

There is no need for those cumbersome step tracking-ring stabilization processes, and there is no need to cut into the opponent's rear hemisphere for stable tracking; The greatly shortened aiming time makes it possible for one side in an air battle to complete a successful lethal attack and shoot down the other side as long as it accurately points the nose of the aircraft at the opponent within the range of the cannon.

This thing is simply cross-era!

The latest domestic J-7 is a cannon, and the J-8 that is now flying is still a cannon.

Since he has left Chengdu, Qin Feng does not know that Tu Lao has begun negotiations with Marconi Company on these electronic equipment, and a few years later, this improved J-7IIA fighter is Qin Feng to test fly.

Qin Feng's question made Boileau's face hesitate slightly.

Is it that easy to aim at the cannon hotline? How could there be such a fighter designed ten years ago?

Only the Mirage 2000 has achieved this feature!

Can they deny it now? Say you don't have this kind of technology?

Of course not, doesn't that make it seem that French aviation technology is not advanced enough?

In fact, France's aviation technology is still a notch lower than that of the United States, but how can they verbally admit defeat?

He couldn't help but secretly complain in his heart, thinking that these people from the East are really not easy to fool, this is to let himself introduce the Phantom 2000!

Since the Mirage F1 is not good, let's move on to the Mirage 2000.

So, Boileau continued: "We have implemented hot-line aiming of the cannon on the Mirage 2000, but this fighter is still under development and has not yet been fully finalized into service, if you want to buy it and immediately form a combat force, I still recommend choosing our Mirage F1."

That's right, the Mirage 2000 has been in development for several years, and the No. 1 prototype first appeared at the Fainsberg Air Show in the summer of 1978 and made a big splash, shattering the mystery that delta-wing fighters were not suitable for low-speed flight. Prototypes 2, 3 and 4 were then completed and entered into a busy test flight, which did not begin production until November 1982.

Of course, we have the technology of hot wire aiming for the cannon, but the carrier aircraft has not yet completed the test flight, which is not a shame, after all, our Mirage 2000 is also a third-generation aircraft, and we are not comparable to the United States, earlier than the Soviet Union.

"Can you please tell us about Mirage 2000?" General Lin asked.

Sure enough, the Orientals are very interested in their own Mirage 2000! Boileau was overjoyed, although he did not sell the Mirage F1, but if the Mirage 2000 could be sold to China, it could also greatly alleviate Dassault's tight financial situation.

"Okay, please read on." So, Boileau could only continue to introduce.

The room went dark again, and Boileau took out the second set of slides, anyway, the Phantom 2000 is not a secret, after Dassault developed it, it wanted to open up overseas markets.

The performance of the Mirage 2000 is excellent, but unfortunately it was born at the wrong time, and the French Air Force still uses a large number of Mirage III and Mirage F1 fighters. The immediate demand for the Mirage 2000 may be only a few hundred.

This medium scale simply cannot make Dassault profitable, and even the cost of research and development cannot be recovered, and even if the French Air Force agrees to a full replacement, it will take quite some time. And the European customers have basically been monopolized by the American F16 fighters. In this case, China is their biggest market.

Now that they all know about their Mirage 2000, it's time to introduce them to it.

"Look, this is our Mirage 2000." Boileau released the next slide and slowly turned his head back to look at the screen.

Qin Feng's eyes widened, this was a very rare structural diagram! The French are so interesting.

The so-called structural diagram is as if the outer skin is transparent, and the inner partition frame, girder and so on, are clearly drawn with the principle of perspective.

For aircraft designers, seeing the structural drawings can be huge, and who would have thought that they would be able to see the structural drawings of France's most advanced third-generation aircraft?

"Oh, shit." At this moment, Boileau turned around and saw the content of his slide, and immediately became angry, who did it?

This is the internal R&D data, the slides used by everyone in meetings to study problems, or when reporting to the Air Force, how did you bring it here?

Boileau took the slide down, and looked at the people present with relish, regretting that he had taken it wrong.
