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

Meeting foreign delegations can only be regarded as an episode.

For Chang Haonan, the most important thing right now is to continue to follow up on the 83rd Project.

It can be seen from the previous aero-engine stability evaluation standards that, given his current situation with a future perspective, the safest route is to gradually increase his influence through the development of technology.

If it were not for the excellent performance of the turbojet 14 after improvement, it would not be so easy for the Science and Technology Commission to make up its mind on establishing an independent aviation industry system.

In the following days, the August 3rd Project Team maintained three-front operations at the same time.

Some people stayed in Fucheng to continue the second-stage full-life test and other test subjects. By the way, they assisted Liu Zhenxiang in supplementing and revising the aviation engine ground simulation test standards.

另一部分人在盛京，负责把410厂新生产出来的两台涡喷14原型机与歼8-3的03号原型机进行适配——在喘振事故发生后不久，这架03号机就转场回到了盛京，准备更换新的动力后再继续试飞。

The workload of this task was much greater than expected.

The weight of the two new engines is more than 601 kilograms lighter than before. In order to balance the weight, the Institute had to make small modifications to the distribution of fuel tanks on several prototype aircraft.

Therefore, until Chang Haonan and Yan Chengzhong returned to Shengjing from Fucheng, the flight engine matching work of the No. 03 prototype was not completely completed.

At the same time, on the day that the 624 Institute completed the first phase of ground simulation testing, another turbojet 14 prototype that had already been sent to Yan Liang was hung on the No. 086 aerial test platform of the Flight Test Institute, and the first test was carried out. Aerial platform testing.

Compared with the high-altitude platform, this aerial platform modified from Figure 16 can simulate some more realistic working conditions, and is an indispensable process in the high-altitude test of aeroengines.

Although the 606 Institute is full of confidence in the improved turbojet 14, it still needs to wait until the test flight of other aircraft is completed before the assembly test can be officially started on the No. 03 prototype.

So before that, Chang Haonan's work became a lot easier. He only had to take time to go to the assembly workshop and follow up on the completion of the two full-state prototypes 04 and 05.

This is exactly what he wants.

Although he had already visited Factory 04 once when the No. 112 prototype made its second first flight, he had never taken a closer look inside the workshop like he did when he went to Factory 410.

……

After returning to House 601, Chang Haonan decided to take a night's rest.

Although he lived in a guest house for two people in Fucheng, the conditions were pretty good in this era, but unfortunately, he met a roommate who snored heavily, and the work was very intensive, so he had to work hard during this period. Suffering from mild sleep deprivation.

Now that I finally returned to my single dormitory, I had to catch up on my sleep no matter what.

However, Yao Mengna, who was traveling with her, was in high spirits.

"Junior brother, are you free tonight?"

Before the two separated at the entrance of the stairs, she called out to Chang Haonan who was about to take out the key and open the door.

"night……"

Chang Haonan hesitated.

Naturally, I didn’t have any plans for my itinerary, but I didn’t really want to go out.

Although he worked very hard, according to the custom of later generations, he was essentially a homebody.

Although it cannot be called social fear by any means, if possible, people generally prefer to stay at home.

However, this moment of hesitation changed its meaning in Yao Mengna's eyes——

Her original intention was to ask Chang Haonan if he wanted to go out for a meal together.

When she was in Fucheng, she lived with a married female engineer, who introduced her to many places suitable for two people to eat near 601 House.

But just after she blurted out that question, Yao Mengna almost immediately realized that she had said something sarcastic.

What does "Are you free tonight" mean?

This sentence can obviously have many meanings depending on different understandings.

As a girl with always-on business intelligence, Yao Mengna always pays attention to her speech and behavior.

It's just that when facing Chang Haonan, Ling Guang's mind often slows down.

This symptom has probably become more and more obvious since the incident involving the senior student...

"It's so disgraceful..."

Yao Mengna was upset.

How could you say such outrageous things?

And now it was impossible for her to explain it, as that would only make it darker and darker.

I can only pray that my junior brother, as a qualified piece of wood, will not think too deeply...

The best outcome is for the other party to directly tell you what she wants to do.

This explanation makes it less obvious that there are no three hundred taels of silver here.

However, she was afraid of what would happen. She saw Chang Haonan who was silent, lowered his head in contemplation, and looked like he was in a dilemma.

In fact, the question just now would not cause any ambiguity at all under normal circumstances.

Unless someone has some evil thoughts.

Therefore, the latter actually didn't think too much, he was just worrying about the time he planned to use to catch up on sleep.

But Yao Mengna next to her was already feeling guilty, and seeing this scene made her whole body numb.

Then she heard her junior brother's answer:

"I've been too busy during this period. I'm going to rest alone at night."

Mainly because of the fatigue after suddenly relaxing, Chang Haonan was already a little over the top, so much so that he opened the door and walked into his dormitory without even thinking of asking the other party's purpose.

"not me……"

Yao Mengna, who stayed in the corridor, looked at the door that was slammed shut in front of her, her mind already turning into a ball of mush.

"Resting alone...why does he emphasize 'alone'?"

"Did he ever want to go anywhere else?"

"He doesn't think I'm a casual woman..."

"And he seemed to have rejected me?"

"This is different from the plot my best friend told me before..."

She didn't even know when she opened the door, but by the time she realized it, she was already lying on the bed.

The last time I felt so embarrassed was the last time.

"Ugh……"

Yao Mengna wished she could have slapped herself five minutes ago.

She looked at the palm that had been raised in the air, and finally slapped it hard on a stuffed bear beside the pillow.

On the other side, Chang Haonan quickly changed into pajamas after returning to the dormitory and threw his entire body on the bed.

"I seemed to have forgotten to ask my senior sister what she wanted to do with me tonight..."

Drowsily, he also vaguely felt that something was wrong.

"Forget it...don't care, I have to go to Factory 112 tomorrow morning to check on the final assembly situation. Then I'll ask my senior sister to go with me. She should be familiar with it..."
