The military-industrial scientific research system of the academic master.

While Chang Haonan was watching the Tu-204S in the distance slowly sliding into the parking space from the runway, in another room downstairs from him, Yao Mengna was also sitting on the bed and staring out the window.

It's just that her eyes weren't focused on any particular place, it looked more like she was simply...

daze.

So much so that her colleagues in the same room even called her several times but got no response——

The travel standard arranged by 601 for Chang Haonan is already at the same level as Yang Fenghata and others, but most people still require two people to live in a standard room.

It wasn't until the other party patted her shoulder that she finally came back to her senses.

"What are you looking at? So focused."

Living with Yao Mengna was the same female engineer who was on a business trip to the 624 Institute last time, named He Meiying.

The latter's husband also works in the 601 Institute, but he is mainly responsible for security work, so naturally he cannot go on a business trip with him.

"By the way, after you returned from Fucheng last time, did you ask Chang Gong out?"

He Meiying asked casually while wiping her wet hair with a towel and sitting on another bed.

Gossip is human nature.

What's more, it's the gossip between two young people who have become very famous in the 601st Institute in recent months.

Although there is no such saying in this era, the actual situation is that many people in the same office as He Meiying are waiting to talk about this CP.

"Ah I……"

Yao Mengna never expected that the other party would ask a question of this level, and she was immediately speechless.

"Ah, what? Could it be that the last time you asked me about places suitable for two people to eat near the 601st Institute, you were just trying to treat someone else?"

The fighting power between married women and unmarried women is not on the same level at all.

As an experienced person, even though He Meiying did not have much direct contact with Yao Mengna in her usual work, it was enough for her to see what this young girl was thinking.

"No, I...I didn't make a date." Yao Mengna said, feeling her cheeks feel a little hot.

"what?"

This time it was He Meiying's turn to look shocked. She even stopped wiping her hair with her hands. After a while, she hesitated and asked:

"He refused?"

"That's not true." Yao Mengna shook her head and replied in a somewhat dejected tone:

"Or I don't have the chance to invite you at all."

"On the day I returned to the 601 Institute, I asked him if he was free, but...he just said no..."

He Meiying took a deep breath.

"He said no, and then you never tried again?"

There was quite a bit of hatred in her tone, and it was hard to say who she was targeting.

Maybe it's both.

"He has been busy with the air show since then..."

"Oh my god..." He Meiying sighed and held her forehead helplessly:

"You two are really..."

Then she raised her head and looked at the time on the wall clock next to her:

"It's just about time for dinner. We shouldn't have anything big to do during the air show these days. If you go find him now, it will definitely be fine."

He Meiying was also worried that her CP would not be BEed.

"I..." Yao Mengna's tone was a little shy: "I was just thinking about what clothes to wear better."

At this time, He Meiying noticed three dresses of different colors and styles on Yao Mengna's bed.

She frowned:

"Did you only bring these dresses?"

"That's not true." Yao Mengna lowered her head and took out a few more sets of clothes from the suitcase:

"But I think these three styles are better looking. Is there something wrong with them?"

"That's not true."

"I just think that judging from Chang Gong's usual behavior, he might prefer you dressed like this."

He Meiying shook her head, stood up and walked to the bed next to her, picking out a pair of jeans and a white shirt.

Even though they are part of two separate outfits.

A few minutes later, Yao Mengna stood in front of the mirror after changing her clothes.

In fact, judging from her appearance, it is a bit difficult to make herself look bad.

However, this outfit does have a slightly different feel when mixed together.

At least the advantage of longer legs is very obvious.

"Thank you, Sister He, then I will..."

Yao Mengna was just about to change her shoes and go out when she was pulled back by He Meiying.

"Are you going to go out like this?"

"if not?"

The former glanced down to make sure he hadn't missed anything.

He Meiying was too lazy to talk nonsense, and pulled her aside directly, pressed her on a chair, and then dug out the makeup box from her luggage.

"Just sit here and don't move."

……

An hour later.

When the doorbell of Chang Haonan's room rang, he was summarizing his somewhat detailed thoughts on a piece of paper.

In the nearly ten years from the mid-90s to the beginning of the 21st century, China's military construction went through many detours.

The reasons are naturally very complicated, including simple technical problems, too unrealistic ideas of Party A users, various obstructions and sabotage by internal and external enemies, and even various coincidences.

Therefore, not everything can be leveraged by Chang Haonan.

He needs to promote and use his influence as efficiently as possible.

Project 83 now only has some finishing work left. The subsequent work, including Project 10 and Project 11, will probably be much larger and involve many more fields.

Due to the existence of the system, he does not have to invest all his time and energy in one direction, but can run in multiple threads.

But the human brain is not a computer after all, and even if it is a computer, multi-core optimization will test the level of the software. For example, in the works of a Swedish game company, there are many cases where one core has difficulty with seven cores.

So he needs to roughly divide the projects he can think of into several priorities——

First of all, it must be the third generation of aviation power, which is the turbofan 10 engine.

As the heart of an aircraft, the aviation engine can be said to be the foundation of an aircraft model.

Not to mention that a good third-generation engine core can also expand a complete steam turbine family.

However, although the Taihang Project was established in 1987, by 1996 it was still basically in a state of flux. The overall design plan had been changed again and again but had not been finalized, not to mention the application of various new technologies later.

This is a tough problem in an absolute sense. Even with the help of the system, it cannot be solved by changing the compressor design in half a month.

The second step should be the production of large-size structural parts for aircraft, that is, heavy-duty die forging presses.

The titanium alloy frame of the Su-27 is made of two parts that are forged and formed separately and then welded together.

But on the one hand, titanium alloy welding is inherently difficult. On the other hand, the production efficiency and yield rate are far inferior to direct integrated forging.
