Chapter 401 Final preparations before the first flight

At this time, Chang Haonan was really not with Beijing Airlines.

Since Sichuan Province itself is not an area seriously affected by floods, Factory 132 is located in a relatively advantageous location and is not prone to water accumulation. In addition, the superior unit sent a truckload of soil-swelling water bags at the most critical moment. Due to the superposition of these factors, the entire factory area was far less affected by this wave of nationwide floods than previously expected.

The 01 prototype of Project was not even moved to a high place. After calculation, it was slightly supported in the assembly workshop to a certain height, thus completely avoiding the threat of waterlogging.

Therefore, about half a month after the rain subsided, Rongfei was able to completely eliminate the negative impact of the flooding and began preparing for the test flight according to the original plan.

As a person who played an extremely important role in the early ground testing process, Chang Haonan naturally received an invitation to participate in the first flight ceremony.

Although I had been prepared for this for a long time, when I actually received the call, the feeling was completely different.

If the Chinese Air Force can be simply and roughly divided into two eras, before the introduction of the Su-27 and after the introduction of the Su-27, then China's aviation industry can also be divided into two eras in the same way, and the watershed is Project !

As a third-generation fighter, its excellent performance is secondary. The greater significance is that it is the first model in China to independently complete the entire process from pre-research, project establishment to finalization and service under the new national military standard system. .

Even if there are still some parts on this aircraft that need to be imported from abroad, it will not affect its status in the history of the development of China's aviation industry.

Prior to this, although there were also independent models such as JJ-1, Chujiao-6 and Shuibo-5 that broke away from the technical route of imitating Soviet aircraft, their technical level was either really low, or they failed to enter mass production due to various reasons. In short All have various regrets.

The J-10 is the first time that China has opened up the complete aviation industry chain from beginning to end.

Don't think that the overall design of the aircraft is a simple matter.

People who have done engineering design will know that even watching others complete a project is completely different from doing it yourself.

Only after completing this leap from 0 to 1 can we have the capital to think so.

You know, even more than 20 years later, there are only a few countries that can "save" an aircraft using imported parts.

Those who are difficult don’t know how to do it, and those who know how to do it are not difficult.

It's a bit like writing a paper. When I read papers posted by others, I always feel like "What kind of rubbish can be published in nature?", but when I actually write it myself, I find that what I write is not even as good as rubbish.

Project No. 10 is the first first-class paper completed by China in the field of aviation industry.

And this paper was directly selected into the top journal.

Therefore, the first flight of the J-10 cannot be missed.

……

When Chang Haonan arrived in Chengdu by plane, it was three days before the first flight.

After all, he can be regarded as an insider who participated in Project No. 10, and the treatment he received is naturally completely different.

In the final analysis, other guests who are just here to observe, no matter how high their status, can only be regarded as "outsiders" to the No. 10 Project. Arriving to Rongfei too far in advance, or being too involved in their daily work will make them appear Rather intrusive.

But Chang Haonan will not.

Not only no, even after he arrived at Factory 132, he was personally brought into the assembly workshop by deputy chief designer Yang Wei.

"Mr. Song, Mr. Xue."

Unexpectedly, Chang Haonan saw Song Wenchong and Xue Chishou in front of the No. 01 prototype that was undergoing the final round of testing.

At this stage, as the chief engineer and chief engineer, what they can do is actually relatively limited.

The main reason why I stay here is for psychological comfort.

In the current timeline, due to the addition of Chang Haonan, the No. 01 prototype did not suffer the two heavy losses during the ground test. Coupled with the optimization of the manufacturing process and production management level, the reason for the previous life did not appear. The first flight was delayed due to the discovery of three oil leaks.

"Xiao Chang, come here and take a look at this plane."

After a brief greeting, Xue Chishou directly pulled Chang Haonan aside.

The afterglow of the setting sun filtered through the glass of the factory building and enveloped the fuselage of the No. 01 prototype, giving it a golden luster, as if it was bathed in holy light.

This is of course not the first time Chang Haonan has seen the J-10.

Compared with the first flight state of the previous life, the hardware of the aircraft in front of me has not changed much. The main difference is basically concentrated in the invisible software part.

Especially the flight control program, after integrating the surge prediction and active control system designed by Chang Haonan, it can be said to be completely transformed.

Although this will not directly improve the performance boundary of the aircraft, on the one hand it will be beneficial to flight, especially safety during test flights. On the other hand, it will also allow pilots to more confidently try to squeeze out the potential limit of this aircraft.

In the past, in order to reduce risks, we could only exert 80% of our strength, but now we can exert 90% or even 95% of our strength, and our actual combat level will naturally improve significantly.

Chang Haonan and Yang Wei walked slowly around the plane together.

I really can’t get enough of this airplane.

However, halfway through the second lap, he suddenly frowned slightly.

Because when he habitually looked under the wing, Chang Haonan remembered something that later made the Air Force resentful for a long time.

"Mr. Yang, I see that on our aircraft, the innermost pylon interface of the wing seems to be different from the two outer ones?"

He turned around and asked Yang Wei behind him.

In fact, as a reborn person, he certainly knew that the answer was yes.

The J-10's inner wing pylon is basically designed to carry auxiliary fuel tanks, and does not have a high-capacity data signal interface.

As a result, the two most advantaged pylons cannot carry guided weapons. Even in situations where auxiliary fuel tanks are not required, only the simplest uncontrolled bombs or rockets can be used.

On the one hand, this can save some costs, but it is mainly to leave more space inside the wing for the fuel tank.

Almost all models equipped by the Chinese Air Force in the past were like this.

There is no way. Before the Su-27, the Soviet aircraft that China came into contact with were all models equipped with frontline aviation, with single functions and relatively short range.

In the Soviet army's combat settings, they only need to take off and land from frontline airports to ensure that air superiority is not completely lost.

The Army will take care of the rest.

However, when these short-legged MiGs arrived in China, which has the same vast territory, they had to assume the responsibilities that originally belonged to the homeland defense air force. Therefore, fuel anxiety was generally very serious. From the J-5 to the J-7, China was constantly improving these models. The changing theme is "Let me see where else I can put a gas tank in."

When it came time to design the J-8 and J-10, although the basic range was no longer so pitiful, design habits could be changed at any time. Therefore, these two models still retained a pair of missiles without dedicated data interfaces. shelf.

After hearing Chang Haonan's concerns, Yang Wei's answer was almost the same as the former's expectation:

"Four pylons, two in the middle and two close to each other, are all enough...can the Air Force have so many missiles to hang on?"

"It should be more important to ensure the basic voyage..."

It can only be said that people cannot recognize things beyond objective reality.

In the late 90s, this is really not a problem, because at this time, the mission of the Chinese Air Force is still to simply defend air supremacy and not completely lose it, and to be honest, there are not that many missiles in the arsenal for you to hang, and each aircraft Keeping 4 racks is enough.

But no one could have imagined that in just a dozen years, China would have a new air force capable of both offense and defense.

And by that time, the problem of insufficient racks began to cause trouble.

Four pylons are barely enough for air combat, but if they want to also serve as ground attacks, there will not be enough allocation anyway, so combat units have to come up with all kinds of weird asymmetric mounts.

Although it is not impossible to use, the combat efficiency will be reduced a lot.

Faced with this kind of explanation, Chang Haonan couldn't possibly say that the Air Force would have a lot of demand for ground strikes in ten years. This kind of rack design would be criticized by the troops, so he had to use some slightly more tactful methods:

"This is indeed the case for us at the moment, but hasn't it been decided before that the personal model will switch to a DSI air intake later on. The current version with an adjustable air intake can adapt to a wider range of speed changes, so Will take it for export."

"If you think about the countries that will buy our Chinese fighter jets, none of them need a particularly large range. On the contrary, they all hope that the air force can only equip one type of aircraft that can cover all missions. Then at least it must be able to carry two, two, and nearly four aircraft at the same time. With the need for one air-to-air bomb and two ground-attack weapons, this design may not be conducive to competing with its peers..."

"hiss……"

Yang Wei was originally a genius, but he never thought that he was simply blinded by the current situation.

Now I was reminded by Chang Haonan.

I suddenly felt that the world was vast.
