On the last day of 86 years, Southwest Science and Industry is still busy with green, the completion of the titanium alloy processing base in Guiyang has attracted the attention of almost everyone, under the leadership of Director Bai, the entire team has completed the handover from the Heilong River border port.

The arrival of titanium alloy processing technology equipment has been inseparable, and the equipment installation personnel and technical training personnel of the Soviet Union have once again set foot on the land of a republic.

The only thing worth mentioning is the expression of the Soviet Union when it got the content of the intelligence, it was like burning its ass, and it ran away without caring about anything, it seemed that it was going to verify the intelligence and deal with these troublesome things.

After the equipment was loaded onto the train, the whole team set off for the south again. Part of them went to the southwest science and industry, and some of them went to Hongdu, and Robles, the vice president of the Morozov Test Flight Institute, had the experience of presiding over the test flight of the L39 training aircraft, and this time he was also honorably sent to the south of the Republic to spend the harsh winter.

What they don't know is that the situation in Hongdu now is much more complicated than when Shi Ping visited the Soviet Union two months ago, and the NATO intelligence network has cast a huge net in the Soviet Union, and there is naturally no reason to miss such an important place as the Morozov Pilot Test Institute, and NATO countries have already reacted to the news that the republic has begun to contact the Soviet Union.

Although the Italian Markey Company has already made some concessions, although it is still unwilling to cooperate in the anti-tail spin test flight, in order not to let the Republic and the Soviet Union get too close, the Markey Company sent a large number of technicians to the Hongdu factory to modernize and improve the Qiangwu under the leadership of Chief Lu Shi, and also monitor the cooperation process between the Republic and the Soviet Union.

At that time, what kind of dragon and tiger battle will break out between the Morozov Test Flight Institute and the Marki Company on the foreign land of Hongdu, and how much will it benefit from in the Republic?

That's all for later. Due to the deviation of the historical trajectory, Yang Hui does not know what will become of him in the end. Yang Hui is now staring at the YZ1's large-edged wing technology demonstrator, which has been flying for a month and a half since its first flight. But now the meaning of this test flight is different.

The first few times were factory test flights of the aircraft itself, and they flew very conservatively. Now it is different, this time it will be more bold to test the advantages and disadvantages brought by the large side strip wing, that is to say, the current test flight is the real work of this technical verification aircraft.

"Li Yun, the first few test flights are very conservative, the requirements for the fly-by-wire system are not high, and even a large-scale maneuver has not been done, this time we have to do some large-scale elevation maneuvers that we have never done, and the requirements for the fly-by-wire system are very high!"

Yang Hui didn't bother the test pilot now. He has been concerned about the research of the big side strip wing from the very beginning, which is obvious to all people in Southwest Science and Industry, and now Yang Hui has no worries about the aerodynamic design of the verification machine itself, and the only thing that is not at ease is the three-axis four-redundancy digital fly-by-wire flight control system used by the verification aircraft.

As a member of the development of the digital fly-by-wire flight control system, he is a general. Although Li Yun is only a student who follows his mentor to participate in the project, he can't stand his multi-specialization and multi-ability in fly-by-wire flight control and software programming.

So much so that this time, the two major units participating in the telex flight control 0611 and Hongdu threw olive branches, and they were ready to recruit this talent under their command, but fortunately, Yang Hui had already prepared. Li Yun, a potential stock that has shown extraordinary ability, has long been a member of the Southwest Science and Industry camp.

After taking off, I did a warm-up, and I was about to do a large-scale maneuver test, Yang Hui naturally stood with Li Yun, and any questions could be raised as soon as possible.

Li Yun is the main scientific researcher in the preparation of this flight control. Very confident in the flight control rate in the flight controller.

"As long as there is no problem with the hardware of the flight controller, there will be no mistakes in the entire flight controller, and there will be no major problems with the flight control rate. We ran the simulation many times and it always ran smoothly and error-free. ”

Li Yun is very confident in the preparation of the flight control rate this time. Even his self-confidence infected Yang Hui, the general manager, and the current test flight of the verification aircraft began when Yang Hui took office. There is no room for error.

The test pilot pulled up the control stick, and the aircraft entered the flight stage at a large elevation angle, which clearly showed the superiority of the large side strip wing, which was much better than the large angle of attack climb in the J-74 test flight.

Both aircraft have the same thrust, and the large side strip wing design allows for greater elevation angles and longer climbing times. This is followed by the test pilot's experimental maneuvers for the next test flight project.

Quickly pedaling the rudder, the aircraft entered the hovering flight performance test, which is very important in modern air combat, and the test is not the stable hovering performance, but the instantaneous disk performance.

Instantaneous disk performance is a very important point in the development of the third generation fighter, in the third generation fighter, the emergence of high-performance missiles, what is needed is the first enemy to discover, the first enemy to lock, and then launch the missile.

In order to detect the enemy first, it is necessary to have radar to illuminate enemy aircraft first, the nose needs to be pointed at enemy planes first, and the nose needs to be pointed faster. The nose pointing speed refers to: instantaneous disk.

The demonstrator in the air did this action, and after the aerodynamic improvement of the large side strip wing, the test pilot and the ground measurement and control personnel were surprised to find that the instantaneous disk performance of the aircraft with the large side strip wing design has also been greatly improved.

"Chief Engineer Yu, you take a look at this measurement and control data, this is a new situation that we did not find in the initial wind tunnel test, the design of the large side strip wing has a great increase in the instantaneous disk capacity, and the emergence of this point once again raises the importance of the large side strip wing technology to a higher level."

As he spoke, Liu Jun handed the measurement and control data he had just gotten in his hand to Chief Engineer Yu, although the plane had not yet landed, there was already a huge sensation on the ground.

Yang Hui, who followed closely, also learned of this major good news, and the large side strip wing has increased its instantaneous disc ability, which is another new situation.

Around a large group of people here, not only the scientific research personnel of Southwest Science and Industry, but also the technicians sent by Northrop couldn't help but be happy, when Northrop studied the small side strip wing, he did not notice this situation, and now a new situation has come out as soon as he experiments, which is really true knowledge from practice!

"It is indeed a new situation, which shows that we have not explored the large side strip wing enough, and now we need to further increase investment in the research of the large side strip wing, and strive to complete the test of the large side strip wing before the end of 87 years, and thoroughly master this technology."

Yang Hui first stated that he would increase investment in the technology of large side strip wings, and Northrop's technical director also followed suit, saying that he would ask the U.S. parent company to discharge more technical personnel and provide more scientific research equipment.

Leaving the crowd of excited technicians, Yang Hui came to the side of the runway, waiting for the test pilot to drive the plane back safely.

He personally moved the boarding ladder to the side of the test plane, and went up to help the test pilot open the canopy, and shook hands with the test pilot for the first time to congratulate him.

"Thank you, this test flight allowed us to get data that we had never found before, with the support of this data, we have a deeper understanding of the aerodynamic performance of the large side strip wing, and it will be up to you to continue the test flight in the future!"

Although the test pilot is not the main force of Southwest Science and Industry Yan Xiufu Captain, but also experienced, since the beginning of the Jianjiao 7A has been stationed in the Southwest Science and Industry to carry out flight test tasks, the Southwest Science and Industry developed Jianjiao 7A, J-74 aircraft have a deep understanding.

The moment I did the instantaneous disc test flight just now, I felt the difference between this large side-strip wing test machine, and the instantaneous disk capability has indeed been greatly improved, which is simply the difference between the old J-7 aircraft and the sky and the ground.

"Definitely, definitely, I didn't expect this new situation, and it is still a little difficult to calm down, and I will go all out in the future test flights."

Can you not be happy and excited? To make a figurative metaphor, the stable disk is a small radius turn of the ground car, and the instantaneous disk is a more awesome drift, and the normal turn is definitely not as exciting as the drift (to be continued.) )
