Chapter 60 Shocking words (2 in 1) (page 12)

"Of course there's no problem with that, but I need to know what you're going to say first, so that I can be prepared so that if something goes wrong, I won't be unable to step down."

Lin Shikuan agreed to Chang Haonan's request without much thought.

Mainly because he was about to have a psychological shadow on speaking.

After all, others are reporting on xx progress in their work. Even if there is nothing worth mentioning, everything is going well. Such a comparison makes their group very useless.

"It's nothing, but I have basically determined that the existing wing design needs to be modified to a certain extent. As for the specific data, I am still calculating it. If nothing else, I will probably get it by this time tomorrow."

This explosive news made Lin Shikuan almost breathless.

He did think that Chang Haonan could help them fight a comeback, but he never expected that it would happen so quickly...

"Dr. Chang, modifying the wing design is not a trivial matter. Are you...are you sure you can come up with a feasible modification plan in just one day?"

"No, no, no, you misunderstood. Of course, it is impossible to know how to modify the wing in one day." Chang Haonan waved his hand and explained: "But it is enough for me to confirm that there is a problem with the wing and it must be modified."

"Cough cough cough-"

Lin Shikuan, who had just managed to catch his breath, held it back again.

This time Chang Haonan did not continue to make shocking remarks, but quietly waited for him to recover.

"But what you just said is half right. If you use traditional design methods, then modifying the wing is indeed a matter that affects the whole body. But if digital design can be realized, then such a magnitude of modification will not delay Too much progress.”

"But the 83rd Project has not yet achieved full digital design." Lin Shikuan said, rubbing his chest that had just stung due to a violent cough.

"So Lin Gong, you have to speed up the progress and let the other teams of the 83 Project see that the digital design team is not only not a burden, but can also help them greatly improve their efficiency."

Chang Haonan's words made Lin Shikuan's eyes suddenly brighten.

"You're right, Dr. Chang, you're right..."

The latter turned around and strode out of the room, returning to the computer room where everyone was just now.

"Work overtime tonight!"

……

The day passed quickly. After dinner the next day, Lin Shikuan took Chang Haonan and Yao Mengna to a large conference room.

After all, the progress seminar is required by every group involved in the 601rd Project in the Institute, and some groups with more complicated work even have to send several people over.

As soon as the three people entered the door, Yang Fenghata, who was sitting at the head of the long conference table, noticed this.

"Xiao Chang, Xiao Yao, how do you two feel about being in the digital design team? Did Lin Gong help you get familiar with the work?"

Lin Shikuan almost rolled his eyes when he heard this question - he didn't feel that these two people needed him to help them familiarize themselves with the work. In the past day or so, he had been led by the other party to make a lot of progress.

It is no exaggeration to say that this day and a half more work than they have done in the past year and a half.

After all, after working overtime last night, everyone in the team was convinced that they were finally heading in the right direction.

"We have been working on it for more than a day, and I feel pretty good. The forest workers are very efficient. They just didn't find the right direction before."

Chang Haonan took the opportunity to help Lin Shikuan and others explain, and then received a grateful look from the latter.

When he was just reborn, he had already thought about using the system to improve the power of the entire Chinese scientific research system.

But this can only happen step by step.

Chang Haonan, who was a screw in the military industry in his previous life, had no decent management experience at all. Although he had taken charge of several projects, they did not require any complicated division of labor and collaboration, so that the system evaluated his management ability at level 0 and 0 experience.

This digital design group with a simple structure, generally young members, and no pretensions or baggage is just right for a novice like Chang Haonan to hone his management and organizational skills.

Therefore, he would find ways to boost the confidence of Lin Shikuan and others.

In fact, since yesterday afternoon, the system has shown that Chang Haonan's management ability experience has been slowly increasing, and it has reached 15 o'clock just after receiving Lin Shikuan's gratitude.

While the three of them were talking to Yang Fenghata, other participating project members also entered the conference room one after another.

After everyone sat down according to previous habits, the seminar officially started soon.

Since Chang Haonan had never been exposed to projects related to the J-8 before, and the August rd Project was indeed somewhat legendary to this generation of military workers, he listened to the whole process with great interest.

In general, the test flights of the three prototypes went relatively smoothly, but some teams also mentioned some problems.

For example, the WP14 engine is still not mature enough and will induce surge under certain circumstances, especially at high speeds. However, the probability of this problem is very low, so the specific reasons still need to be further investigated.

Still WP14, the engine life, especially the life of the turbine blades as hot-end components, is not ideal and there is still room for improvement.

In addition, as a typical second-generation high-altitude and high-speed interceptor aircraft, there are problems with the stall angle of attack in a specific speed range and the available overload at high angles of attack. It needs to be limited by the flight control software to avoid entering a stall or spin state.

In addition, the fire control equipment group stated that the imitation progress of the PL1471 air-to-air missile, an Aspadian-made model matched with the 11G radar, is so slow that they simply do not have enough ammunition for over-the-horizon attack testing.

Finally, there is a somewhat peculiar problem. When the J-8-3 uses the innermost pylon of the wing to launch PL8 air-to-air missiles, there is a certain probability of causing the engine to stop.

The reason for this matter is not complicated. The smoke and dust generated when the propellant of the PL8 missile is burned is very heavy, and the interference with the air inlet when the inner pylon is launched may lead to insufficient air intake or turbulent air flow.

It's just that this is the same problem as the slow progress of the previous PL11 missile, which needs to be solved by the missile research and development unit.

As for the problem of the WP14 engine, it is also not something that the 601 can handle. However, even if the worst possibility is considered, the J-8-3 can temporarily use the WP13F engine with a slightly smaller thrust, so that it will not be completely unable to reach the sky.

Therefore, after listening to the previous report, both Yang Fenghata, who presided over the meeting, and the team responsible for these tasks were in a relatively comfortable mood.

"Then finally, let the digital design team talk about their progress."

Yang Fenghao looked at Lin Shikuan, who was sitting in the back corner of the conference room.

Since the digital design team is unable to guide aircraft design, they have almost become outsiders of the 83rd Project, and have been placed at the end of the report for a long time.

But this time, it was not Lin Shikuan who stood up, but Chang Haonan, who was holding a report in his hand.

To most people in the room, this was a new face.

And usually, when the digital design team gives a report, it means that the seminar will end soon and everyone will relax.
