Chapter 72: Return to Beijing Airlines (25 for Alliance Leader Flankerr)

With the cooperation of two people, the design optimization of the new wing of the 83 Project was completed in only about 20 days.

The final simulation results show that the improved wing can greatly improve the maneuverability of the aircraft, the position of the aileron reaction in the bombed state is greatly delayed, and the available overload at the stall angle of attack and the high angle of attack are also significantly improved.

Of course, the specific performance data will not be known until the wind tunnel test is completed, and the new wing is built and installed on the No. 04 demonstration aircraft for test flight.

In fact, if the 83 project is simply replaced with a double delta wing, then there is still potential for further improvement in this aspect of performance.

But this deviates from the original intention of the development of the J-8 model.

You know, the performance of the 1471G radar that is expected to be replaced by the 83 project is almost the same as APG66 (V), and it is even possible to directly replace the 1473 type derived from it in the future, that is, the same radar of the J-10, plus the foundation of the double-engine heavy interceptor, so the cost is not low.

Under the condition that both Project 10 and Project 11 are progressing smoothly, Project 83 can only be positioned as a specialized high-altitude and high-speed interceptor aircraft in the People's Air Force, taking the line of differentiated competition, and doing things that are not easy for two third-generation aircraft.

Therefore, all the changes made so far must be to optimize other performance as much as possible on the premise of ensuring its high-altitude and high-speed capabilities.

If it becomes an aircraft with no obvious strengths and weaknesses, it will have no advantage compared to the future J-10 and J-11.

Under the guidance of such ideas, combined with the current level of China's aviation industry, Chang Haonan has done his best in wing design.

In addition, while waiting for the calculation results, he also completed the explanatory document promised Xu Yang by the way, and handed it to the other party on the last day before leaving the Institute of Computing Technology.

……

Originally, Chang Haonan should have followed Yang Xia back to Shengjing after the work here was over.

But if you count the days, it is not a few days before the graduate interview of Beijing Airlines University.

Although with his current achievements, even if the confidential part of the 83 Project is excluded, this interview is also a formality based on the first grade point in the whole grade, a paper in the Journal of Aeronautics, and most importantly, the identity of the first person to complete the advanced technological achievements declared by 603.

But this cutscene still has to go.

Just like more than 20 years later, a professor at Beijing Aviation University became an astronaut, and he also had to hold group meetings and preside over students' graduation defenses in the space station.

In 1996, there were few places to connect the Internet, the upper limit of Internet speed was generally 56K, and the better conditions could reach 128K, and it took a while to open the simplest web page, so an online interview or something......

Don't even think about it.

Of course, considering Chang Haonan's special situation, the college also said that if he really can't come back, he can use the camera to record a video for a few minutes and play it on the spot at that time.

However, he himself is now in the capital, and after the wing improvement is completed, there seems to be nothing particularly urgent in the short term.

What's more, the act of participating in an interview by video itself has a sense of beauty that there is no silver in this place.

So after thinking about it again, I decided to explain the situation to Yang Fenghata and go back to school to handle the matter of Zhibo.

"Sister Xia, I want to have a phone call with Chief Master Yang."

Although this call has nothing to do with the specific content of the wing improvement, after all, it involves the itinerary of him and Yang Xia, so it is safer to contact him through confidential means.

"Phone? But we will return to Shengjing tomorrow or the day after tomorrow. Yang Xia looked at Chang Haonan with a puzzled expression and asked.

"This ...... I have something going on at school, so I may need to stay here in the capital for a few days. ”

Yang Xia was tasked with assisting Chang Haonan, so she did not interfere with the other party's decision, but only led the latter to an office at the Institute of Computing Technology, where there were several red telephones.

"You can use any one, I'll wait for you outside."

After finishing speaking, Yang Xia turned around and left the room.

Chang Haonan quickly dialed the phone number of Yang Fenghat's office and explained the situation to the other party.

"Of course it's fine."

The reply over there was also very pleasant.

After all, Chang Haonan is not a member of the 601 Institute in the end, and in the past month or so, he has also made great contributions to the entire 83 Project.

Even the mere early detection of flaws in the wing design can save the project several months.

Not to mention that he directly solved this problem, and even optimized the low-altitude and low-speed maneuvering problem that has plagued the J-8 for many years.

"In that case, I'll ask Engineer Xu Jinxu to come over for you, and let him bring the data back with Yang Xia."

Obviously, due to the importance of this data, it can't be brought back by Yang Xia alone, and it must be accompanied by a second person with the same level of secret.

And Xu Jin is the old engineer mentioned by Lin Xikuan before, and he had a relationship with Chang Haonan at the first progress seminar.

It was quite thoughtfully arranged, and the latter naturally could not have any opinions.

In addition, perhaps considering that after the wing design improvement work is over, it will take some time to manufacture a new wing, and Yang Fenghata even specially approved half a month's vacation, so that Chang Haonan can concentrate on handling the affairs of the school, and by the way, he will have a good rest.

Of course, if there is any emergency in the middle, you still have to make sure that you are on call.

So, the next morning, after Xu Jin, who rushed to the capital with the wind and dust, completed the handover, Chang Haonan finally returned to Jinghang University again.

At this time, it was already mid-August, just in time for the 1996 college freshmen to report -

Because of military training, they have to arrive at the school about half a month earlier than the old students.

So the school gate was filled with new students who were a little dazed as usual, as well as parents who came to see off the students, which made Chang Haonan take some effort to finally squeeze into the school.

"Hello classmates, do you need ......?"

Before he could recover his senses, he heard a somewhat familiar voice.

"Old Wu?"

Chang Haonan raised his head and saw Wu Yifan standing under a parasol on the side of the road, obviously taking him for a new person with a suitcase in his hand.

"I'll go, Nanshen?"

The other party obviously recognized Chang Haonan: "Why did you come here so early this year?" ”

Then he realized something immediately, and replied to himself, "Oh yes, I have to prepare for the interview ...... the research institute."

"Ahem...... Don't talk about this. Chang Haonan waved his hand: "What are you doing here?" ”

Not far behind Wu Yifan, there stood twenty or thirty juniors who looked like they should be sophomores or juniors at the beginning of the semester.

A little farther away are three tables filled with cardboard boxes, which look like IC phone cards, tape recorders, electric kettles, and other small things.

"Hey, I'm not as capable as you, so I can only take this opportunity to make a little money if Academician Du takes a fancy to go to graduate school......

Today's liver is here, and tomorrow it will continue to be added
