Now, Qin Feng talked about the entire arc-shaped overall windshield, and when he heard Qin Feng's statement, Tu Lao also nodded: "Yes, in the past, we had no choice, but now, we finally have this technical foundation, this overall windshield, we are researching, and in the future, we will equip the troops." ”

In the past, the three-piece cockpit windshield was very popular, even if even the F-14 Tomcat fighter jet, the use of this kind of windshield, first of all, the first benefit, is sturdy and strong, you know, the fighter is often to fly to Mach 2, although the air at high altitude is thin, the impact of the airflow is also very strong, so, this three-piece form of windshield, with two fixed ribs, is the most sturdy and strong.

This point can be seen J-8, in later generations, other domestic fighters have been replaced with an overall arc windshield, but J-8 still uses this three-piece windshield, one of the reasons is for high-altitude and high-speed, after all, the research J-8 special windshield is time-consuming and labor-intensive, and the demand is not large, so it is not necessary.

And the three-piece windshield of the J-7, the glass in front of it is flat, which is also a great benefit.

What are the benefits?

There is no optical distortion.

Inside the curved bubble cockpit, it looks tall, but if you sit inside and look out, you can see that the outside world has changed.

The curved bubble canopy is like a magnifying glass, and the light coming in from the outside will be refracted when passing through the cockpit, resulting in visual differences, which is the same as putting chopsticks into a water bowl and finding that the chopsticks have become bent.

This effect is not a big problem in the rear canopy, if the outside is magnified, it is still beneficial, it is easier to see the enemy aircraft, but if this optical distortion also occurs in the front windshield, it is inappropriate, especially for the previous era of optical shooting sights, this is simply catastrophic.

If the windshield in front of you becomes curved, how do you aim? In the past, the shooting sight, even the measurement distance was converted according to the wingspan, if the front windshield is arc-shaped, the light is bent, the measured data is absolutely inaccurate, so the windshield in front of the cockpit canopy is made into a flat plate, in order to avoid this refraction phenomenon, there is no other way.

This is another big problem.

Fortunately, now, they already have this condition, because their cannon aiming, has adopted the hotline method, through the calculation of the on-board computer, a hotline is formed on the front head-up display, as long as the hotline is aimed at the other party!

In the era of missiles, of course, it doesn't matter how this windshield is refracted, only with a direct-aiming weapon such as a cannon.

Now, if your windshield becomes arc-shaped, then you only need to modify the internal program of the computer to take into account the refractive light factor of the curved windshield and modify the display of this hotline.

In the West, the advanced third-generation aircraft use an arc-shaped overall windshield, that is, they have all made this correction, so they can now be regarded as having this condition!

In fact, the cockpit of the J-7, the 132 factory has been modified, the earliest cockpit canopy was opened forward, the success rate of ejection was very low, and later it was changed to open backwards, and this front windshield was still sandwiched with a piece of bulletproof glass in the past, it is precisely because of this bulletproof glass that the front vision is very blurred, so, the later J-7 production type, this bulletproof glass was directly removed, so that it was simplified, and the vision was clearer.

Now, Qin Feng proposed to improve the cockpit windshield, from the pilot's point of view, any pilot does not like the front windshield bulkhead, it is too eye-catching, there was no way in the past, it must be endured, when I saw the cockpit canopy of the F-16, no one liked this kind of windshield anymore.

The pilots of Lao Ba must have also criticized this kind of windshield.

The canopy and windshield are transparent, but not glass at all, it belongs to plastic, this kind of thing is easy to form, it is not difficult to make the overall curved windshield in front, the difficulty is to have the same mechanical strength as the three windshields, increase the resistance when hitting birds, and make complex optical corrections.

Now, Tu Lao has nodded, this project, we can carry it out now, of course, I can't eat hot tofu in a hurry, I must experiment, it will take a while, but there is no problem with the technical aspects of this project.

Besides, there are many projects in the 132 factory, and the most advanced one is the super seven project developed with Grumman, and the windshield of this project is the whole, so from this project, the technicians of the 132 factory can also learn the design in this area.

Now, this overall windshield has been adopted on the J-7, which is also an improvement, and domestic aircraft in the future will definitely adopt this method in large quantities, although it seems to be only an insignificant aspect, but for pilots, it is crucial.

"I'm looking forward to it." Qin Feng said.

A smile appeared on Tu Lao's face: "Don't worry, there will be bread, everything will be there." "After going to the United States for a while, Tu Lao can also say American proverbs.

"By the way, how is Super Seven progressing?" Qin Feng asked Tu Lao, when the Jian-7 CP finally evolved into the Super Seven, the performance had been further improved, from a modification of a second-generation aircraft to an authentic third-generation aircraft, Qin Feng was still looking forward to this aircraft.

Although the domestic J-10 has been making slow progress, this Super Seven is cooperating with Grumman, so the progress is much faster.

"The feasibility study is almost underway, and the basic aerodynamic layout of the airframe is almost complete." "We are very confident in this project. ”

After finishing speaking, Tu Lao smiled and said to Song Lao: "Old Song, you have to come on, maybe, our super seven can still be exported to domestic sales." ”

Now, the prospect of Super Seven is very good, both the mobility of the third-generation aircraft, and the lower cost, and the 132 factory has a lot of experience in this area, such as the J-7M is a successful example of export to domestic sales.

Hearing Tu Lao's words, Song Lao didn't answer, but just showed a wry smile, of course I have to come on, but now, the design can't be frozen, and even some technical indicators are still being demonstrated, and the most critical engine still has no shadow!
