"As you can see, this is us Mikoyan. Where the Glevich Design Bureau is located, this piece of design office, fast response, and test center is the basic guarantee for our MiG Bureau to quickly develop world-class fighters. ”

Walking to the interior of the MiG Design Bureau, Yang Hui listened to the introduction, and at the same time kept observing the surroundings, hoping to see some clues, or get inspiration from some places, and retrieve some temporarily forgotten memories of the previous face.

But the time span does have several years, and Yang Hui has been thinking about the problem of building a fast reaction center after he goes back, and there is really nothing else to pay attention to.

When the group walked to the design office design center of the MiG Design Bureau, they paused for a long time, and after some negotiations, several Soviet soldiers came to inspect Yang Hui and others.

Up and down, before and after, Yang Hui and them were checked, which allowed them to be brought into the office area to visit, which made Yang Hui have some expectations, and the design thinking and level of the MiG Design Bureau still have some things that can be studied.

Walking into the corridor, Yang Hui felt an obvious tense working atmosphere, and from time to time someone walked past Yang Hui, but he was not surprised by Yang Hui's strangeness, at most he looked at it twice and left.

The MiG Design Bureau is really famous, and many people come to visit every year, not only the internal personnel of the Soviet Union, but also other customers who are ready to purchase MiG series aircraft will also visit the MiG Design Bureau, not to mention peers like Yang Hui.

The only bad problem is that the security work of the MiG Design Bureau is too good, and Yang Hui went into the office area for an hour and did not see anything meaningful. As he continued to look at the internal situation of the MiG Design Bureau, a middle-aged man in the company finally spoke.

"This is the MiG-29 fighter that was unveiled this year. Can we take a look at this aircraft, the masterpiece of the MiG Design Bureau. We are interested. ”

Seeing the middle-aged man who was not smiling and pointed to the MiG-29 on the wall to choose a photo, Yang Hui was also interested in visiting the MiG-29, which was also a good opportunity.

In the office design center of the MiG Design Bureau, it has always been guarded like a thief, and it is difficult to see anything, and it is also a good choice to go to the outfield to see the test flight of the MiG-29.

The MiG Design Bureau and the USSR Foreign Ministry also discussed at this time, and it seemed that the MiG Design Bureau was not very willing, but the USSR Foreign Ministry clearly had the upper hand in the end.

"Okay. You can take a look at the test flight of our outfield aircraft, our MiG-29 will be an unrivaled maneuverable fighter, it has super combat ability, and it is definitely the king of world fighting. ”

Although he was reluctant to let Yang Hui and a few people go to visit just now, his arms couldn't twist his thighs, and under the arrangement of the Soviet Foreign Affairs Department, the test flight tour was finally opened. Since he couldn't resist, he happily accepted it, and boasted about the MiG-29 along the way.

Walk to the meter test flight station. The crowd saw a large number of planes waiting for test flights, some of which were ready to be delivered for test flights, and some of which were fighters in the shape of a prototype of the MiG Design Bureau.

Yang Hui saw the MiG-29 aircraft among the many aircraft at first sight, but there was no way that this MiG-29 looked too different from other MiGs. It's hard to think of anything outstanding.

Seeing that everyone recognized the MiG-29, the accompanying officer of the MiG Design Bureau once again boasted: "This is our MiG-29 aircraft, and he is the pride of our MiG Design Bureau." Presumably you only learned about the existence of this aircraft this year, but I will tell you: the great Soviet Union, the powerful MiG design bureau. Having put this advanced aircraft into service a few years ago, the aviation industry of the USSR was no worse than that of the United States. ”

Just when the MiG Design Bureau was immersed in its own goodness. Yang Hui didn't have much of the heart to continue to listen to this guy's bragging, because there was a strange MiG-29 prototype that entered Yang Hui's sight.

Although this bizarre MiG-29 is covered with cloth at the nose, this does not affect Yang Hui's observation, and the almost yellowish color on the fuselage and wings makes Yang Hui understand that this aircraft is no longer the early MiG-29 model.

The early models of the MiG-29 fighter used not aluminum-lithium alloy, but authentic aluminum-magnesium alloy, which means that the early MiG-29 prototype was a silver-white aircraft, which was definitely different from the aircraft that Yang Hui saw now.

Seeing this aircraft, Yang Hui was silent, the MiG-29 has begun to improve the fuselage material, the weight reduction brought by the use of the new aluminum-lithium alloy will bring new combat performance to the MiG-29, if the MiG design bureau can successfully use the aluminum-lithium alloy on this new MiG-29, the situation of the MiG-29 with short legs will be greatly improved.

Why? Because the benefits of aluminum-lithium alloy weight reduction can definitely be achieved, the new MiG-29 can increase at least one ton of oil, as for the space for loading fuel, Yang Hui also roughly saw some clues: the new MiG-29 improved side wing auxiliary air intake has disappeared, which is obviously used to load fuel.

Overall evaluation of this aircraft, Yang Hui can only say: If this aircraft can really be completed, the problem of short legs of the MiG-29 can indeed be greatly improved. But Yang Hui is not very optimistic about the improvement of this aircraft now, which is not only an inference from Yang Hui himself, but also a combination of Yang Hui's memories in later generations.

In later generations, Yang Hui has not heard of the actual production and deployment of a large number of range extender types of the MiG-29, and Yang Hui has not seen the MiG-29 that has canceled the auxiliary air intake.

The most common in later generations is that there are some early models of MiG-29 improved installation of spine protection fuel tanks, or some small batches of experimental equipment with several extended range types, but that is after the recovery of the Russian economy after 2000.

This shows that the aircraft that Yang Hui sees now must not be mass-produced MiG-29 improvements, which is a bit of a taste, and it is only October 86, looking at the appearance of this aircraft, because it should have been put into test flights.

Judging from the design and flight speed of the MiG Design Bureau alone, it is absolutely impossible for such an improved version of the MiG-29 aircraft to be dragged to 91 (the MiG-29 aircraft after 91 was almost semi-discontinued), but this aircraft has not been seen in later generations.

Then it can only be another possibility, the MiG Design Bureau encountered difficulties in the development of this aircraft, which led to difficulties in the finalization and production of this aircraft, and even dragged it out after 91 years, so there was no mass production.

Seeing that this aircraft boldly used a lot of new materials, Yang Hui had roughly guessed the reason why this aircraft was not put into service, because this improved MiG-29 model had encountered problems in the development.

It is nothing more than that there is trouble in the use of new materials, and there is no problem in reducing the weight of new materials, but the use of new materials, after weight reduction, will change the center of gravity of the aircraft, and after the center of gravity changes, the development of the aircraft will definitely take a lot of energy.

On the other hand, the new material will have different mechanical properties from the old material, and different mechanical properties, which will definitely give the MiG design bureau a headache for the first time in contact with this material, and the fatigue damage speed of the aircraft is different, and even a bad aircraft disintegration is possible. In Yang Hui's view, the problem with this aircraft should be the extensive use of new materials.

Pointing to the lonely yellow-skinned MiG-29, Yang Hui asked tentatively: "This is the MiG-29?" Since it is an aircraft that has been in service for several years, will the prototype be pulled out and continue to fly for testing? Or is this a new MiG-29 aircraft? ”

As soon as he heard Yang Hui's words, one of the accompanying personnel of the MiG Design Bureau was so frightened that he immediately covered up something.

"You don't have to worry about this, according to the plan, you just look at the test flight of the MiG-29 aircraft, and there will be a MiG-29 plane that has just left the factory to fly here, come with me, don't look at things that shouldn't be seen."

As he spoke, he was about to take Yang Hui and the others to the side, and at the same time, several other security personnel who accompanied him quickly ran to the side of the yellow MiG-29 and beckoned the ground crew to remove the plane.

Yang Hui and several other people in the team naturally saw the problem here, and looked at the yellow-skinned MiG-29 again before leaving.

In fact, just as Yang Hui thought, the yellow-skinned MiG-29 aircraft that Yang Hui saw just now was the MiG-29M, or MiG-33, and this aircraft had never been put into production at all, because the new materials of this aircraft were used to bring a lot of problems, and the aircraft was finalized until 91.
