Chapter 613: The feeling of being full of motivation is so cool!

Although this level of change cannot be said to upgrade the entire standard, it will indeed bring great convenience to the design work.

You must know that aircraft design is actually a very complicated job. In addition to people like Song Wenchong, Yang Wei, and Chang Haonan who do the overall design, there are actually many people who are not noticed and are responsible for subsystems or more detailed parts. Technical staff.

They may not have particularly high talents or extraordinary abilities, but they are the backbone of completing a project.

To some extent, it is also the decisive step of a project.

Chang Haonan before his rebirth should be considered a relatively important one among this group of people.

This improvement in design methodology is of great significance to them.

This can naturally improve the work efficiency of the entire project team.

Of course, this aspect of work does not require Chang Haonan to do anything. There will be people from Rongfei Group who are responsible for standardizing design methods.

If the effect is good, it will gradually be promoted to all units under the aviation industry, and will eventually become a standard when the next standard is updated.

Just like digital design and pulsating production lines.

This is also the benefit of the entire aviation system maintaining a national chess game.

If we really follow the method of the previous life and split the aviation industry into the first group and the second group in parallel, differences will naturally and slowly arise in many places.

Not to mention a lot of internal friction, even if they want to merge back in the future, it will be troublesome.

"Speaking of which, the No. 04 prototype has entered the final assembly process. Do you want to take a look?"

Xu De, who had not spoken for a long time, suddenly suggested.

After all, he was the deputy chief engineer in charge of aircraft production. Although it was impossible for him to know everything about design at this level, he still couldn't say anything in front of Chang Haonan and Yang Wei.

"No. 04... your speed in building prototypes is quite good..."

It was only one year after its first flight. Excluding the No. 02 aircraft used for static damage testing, there was actually a third aircraft available for test flight soon.

"Well...the state's overall allocation to the aviation industry has increased a lot this year. Specifically for key centrally managed projects like our No. 10 Project, this year's budget has increased by nearly a quarter on the original basis. , the funds should naturally be abundant..."

Song Wencong replied from the side.

Although the person who directly manages the project budget should be the chief engineer Xue Chishou, the chief designer is definitely aware of the expenses.

After all, not every project can save money like Chang Haonan with its incredible efficiency——

The expenditure characteristics of turbofan 10 and die forging presses are that the funds originally expected to be allocated in five years are concentrated in two years, and then the results are quickly withdrawn.

If this method of burning money was left in the hands of others, the budget department would be frightened to death.

When talking about this topic, Xu De suddenly became more energetic:

"Yes, I can feel that the above-mentioned views on the aviation industry are gradually changing, especially the financial system, which has gradually regarded us from a bottomless pit of burning money as an effective investment in the short and medium term..."

"At this point, my colleagues across the country have to thank Comrade Haonan..."

Everyone in Rongfei knows the problem of lack of money best.

Now, although I am not at the point where I can spend it freely, but compared to the past when I wanted to break every penny in half, and even the chief engineer took the lead in setting up stalls on the streets to sell noodles to make a living, it is really better. Don't know how much.

Therefore, the tarmac was filled with happy air for a while.

In fact, there is nothing interesting to see in the assembly workshop, because the prototypes are all produced in a single frame, and each frame may be different, so there is no need for any cutting-edge assembly technology.

It's just that since Xu De mentioned it, it was difficult to refuse based on emotion and reason.

Just treat it as part of the visit.

The real highlight was the Project 10 Category II prototype technology seminar on the second day.

Since in theory, the Air Force has not officially named this equipment, it is Rongfei’s current internal official name today.

Correspondingly, the version that uses a binary adjustable inlet and is currently undergoing test flights is naturally called a Class I prototype.

Of course, under normal circumstances, they are simply called J-10E and J-10A.

……

The Guihang Industry team led by Sun Huizhong arrived on a chartered flight the next morning and were picked up as quickly as possible from Rongfei.

"Mr. Song, Mr. Chang, and Mr. Yang, I'm so sorry for wasting everyone's time."

After entering, the leader, Sun Huizhong, shook hands with the person in charge of Project No. 10 one by one.

"It doesn't matter. Everything happens for a reason. Besides, the project is not rushed."

Song Wenchong immediately said it was okay.

"Yes, it just so happens that I haven't been to Rongfei for more than half a year, so I still had half a day to look at the changes here yesterday."

Chang Haonan also added.

Then, on the way to the seminar, we talked about the situation of Guihang Group:

"By the way, Gong Sun, I was at the Air Force Aviation School before, and I heard that they seem to be preparing to purchase a new advanced trainer aircraft. Is there any news?"

When the matter of JJ 9 was mentioned, Sun Huizhong, who was still a little tired, his eyes suddenly lit up:

"Yes, I wanted to call you to thank you for this matter before, but you were not in the capital at that time, so I couldn't get in touch..."

"There are currently a batch of 26 aircraft ordered there, 6 of which are the same version with formation indicators like the Bayi Performance Team, and the delivery time is very fast..."

"..."

After some greetings, the participants arrived at the venue one after another and sat down according to their respective tasks.

Chang Haonan noticed at this time that Lin Tongxin, who had followed Sun Huizhong to the capital before, was also following him this time, and he also had the title of deputy director of the research laboratory.

Clearly the progress is rapid.

Of course, it also reaped the dividends that no one could use in the past two years of Guihang Airlines Group.

Those who participate in this kind of technical meeting are purely their own people, and there is no need for any opening remarks.

After Song Wencong briefly talked about today's theme, the microphone was handed over to Chang Haonan.

"Comrades, before discussing specific technical issues, let me first give a general summary of the improvement plan for the Class II prototype."

As he spoke, he flipped through the PPT on his computer and showed a rough rendering.

After a brief silence, the audience was in an uproar.

"This……"

"Compared with our current Class I prototype, this plan is a bit different..."

"Yes, without going into more details, the shape of the nose and wings have been slightly changed."

"..."

The technicians sitting below couldn't help but whisper. Even people like Song Wenchong and Yang Wei, who had heard Chang Haonan draw cakes before, were a little surprised.

Although the overall appearance still maintains the characteristics of the J-10 - wing-body fusion, mid-range coupled canard + large delta wing, belly air inlet, single engine and single vertical tail, obvious wasp waist structure...

But upon closer inspection, the difference is not small.

Although the overall size is still the same as before, the entire aircraft has become fuller.

In particular, the cross-section of the fuselage has changed from an approximately perfect circle to an oblate shape that is wider on the left and right.

It even has a slight shadow of the Typhoon fighter jet.

The advantage of this is obvious, that is, the usable volume of the aircraft becomes larger while the measurements remain basically unchanged.

But what's the cost...it's obviously more "fat".

"Comrade Haonan..."

Song Wencong felt a little sweat on his forehead:

"You...didn't say you wanted to be so grand..."

He spoke in a very low voice, obviously worried that his words would be heard by the people below and would affect their confidence in their work.

"And this aircraft, I think, must be at least hundreds of kilograms heavier than the current design empty weight, plus the increased drag caused by changing the area ratio..."

Yang Wei's eyes also trembled a little:

"Although our aircraft is a medium-sized aircraft, we can't completely give up supersonic performance, right?"

At this time, Chang Haonan finally continued to speak.

Not just to the other two chief engineers, but to everyone present:

"I know what your concerns are right now."

Having said this, he directly turned the PPT to the next page:

"Just at the end of last month, the domestic turbofan 10 engine expected to be equipped on the Class II prototype aircraft has completed parameter calibration."

"The first mass-produced model, the turbofan 10A, has a maximum thrust of 13.2 tons at sea level."

“The specialized single-engine model, the turbofan 10B, has been specially adjusted to increase the maximum thrust at sea level to 14 tons, which is a 31% increase compared to the current AL12FN, and has been specially optimized for high-altitude and supersonic thrust. "

"So, there is no need to worry too much about the flight performance after the modification!"
