As the bosses said above, the Ninth Academy involved too many projects, and they were originally just a few reserve talents. Even after these days of large-scale fraud and abduction, it would not be enough to get talents from other units.

Especially in the case of a ten-year turmoil in China, where talent training gaps are generally short of people in all units, it is even more difficult.

If you want to ask for people from Liu Yijiu now, it is a big aircraft project he has long focused on. It would be strange if Sun Daogan can get people.

"Director Sun, let's forget it. We have been short of people here for many years. Can you get people from Director Liu? This is simply impossible. It's good that he didn't have the idea to get people from you Qin Fei..." Wang Kai said with a wry smile.

"But……"

"There is nothing. You can find out if you go and ask, our Director Liu is young, but he is well-known. If the entire military system had not been the 541 base that eventually became a subordinate unit of the Ninth Academy, they would have taken away all the talents there. Other units have been borrowed by the Ninth Academy. Now many factory leaders are looking for senior military officials to ask for people." Wang Kai interrupted Sun Daogan, "If you really want to blame someone, you can only blame yourself. Chief Long has reminded you..."

"How could I know that he was targeting the Yun-Ten Project? At the beginning, when we knew that the Yun-Ten Project was about to stop and put the expenses to the Air Force's radar, we were ready to bring all the teams in Mafèng Mountain..." Sun Daogan was now crying without tears.

He didn't expect that Liu Yijiu would start faster than them.

"In 1979, he had already focused on the Yun-10 project. At that time, there was internal news that the turbofan team 6 was accepted by him first, otherwise. Why would our 611 Institute dare to say that it would provide you with the engine?" Wang Kai shook his head. "Director Liu was in a bad mood these days. He scolded President Wu during the on-site meeting yesterday morning..."

Sun Daogan was stunned.

Wu Tianhai is the chief engineer of the Institute 611

The big guys above are all extremely precious, and Liu Yijiu even scolds him. Could it be that he has a bad-tempered father-in-law?

If so...

Thinking of this, Sun Daogan couldn't help but emit light from his eyes.

"You'd better forget it. Old Wu can't follow you. Although Liu Yijiu is young and shouldn't scold Old Wu, from a technical perspective, Old Wu's thoughts are a bit conservative. Our Ninth Hospital is not like you. The logistics department has spoken out. You have to give as much money as possible. We have no extra funds to invest in issues without great prospects. Old Wu is the chief engineer. Liu Yijiu is the chief designer..."

After Wang Kai's words, Sun Daogan took it seriously.

Liu Yijiu is so young, can he serve as chief designer?

I think about it and understand that I can control such a large base, and even the people below are willing to be scolded. You can imagine how high Liu Yijiu has in terms of technology.

Otherwise, when a technician like Wu Tianhai was scolded in front of a group of bigwigs, he would just throw his arms around and leave and put the stall down. Liu Yijiu would clean up himself.

Sun Daogan is a technical background and knows the temper of people who are skilled. They don’t accept anyone and will not consider any administrative level at all. They don’t care whether they are a big shot or a high status. If they don’t know how to be a profession, it will be difficult for them to obey.

Liu Yijiu didn't care about Sun Daogan's attempt to dig out the chief engineer of his fighter team. After finalizing the new performance standards for the fighter, he rushed back to the base, regardless of the Soviets who had not brought the money.

I have been delayed outside for a long time during this period, and I don’t know what happened to the helicopter inside the base.

So, he hurried back to the base and waited until the matter was handled before negotiating with the Soviets.

He was too lazy to care about the Soviets' reaction.

As for the needs of the Iranians, Liu Yijiu threw it directly to Cao Yuan, the newly established China Precision Machinery Import and Export Trading Company, to deal with it. Cao Yuan and his team were able to do these things, so he naturally had a happy time.

Anyway, if you earn more than you earn, you will be from the country, and you will not be able to enjoy much money personally. If you share some profits and reduce a lot of trouble, that is something that you can't get.

"Director Liu, you are back. We have been looking for problems for a long time now. No one has had a rest during this period. Starting from the inventory of raw materials, no problems were found. The workers' operations are strictly followed in accordance with the process regulations, but now we cannot find the problem..." When the helicopter stopped in front of District 1 for employee activities and on the square where movies were usually played, District 1 Director Wang Yueshan and others were waiting for his arrival.

It's like seeing the backbone.

Liu Yijiu was responsible for a lot of design work for the Zhi91 project, especially the overall design, and he was responsible for the other sub-projects, and then distributed them. Liao Zhuojing was very disdainful of Liu Yijiu's forced intervention at the beginning, but during the previous test process, he found that the aerodynamic layout and overall layout of the helicopter designed by Liu Yijiu did not have much problem with it. Many of them were unable to achieve the difference in processing capabilities and had to make detailed adjustments.

The static pressure test and wind tunnel test of the helicopter both showed good performance.

Unexpectedly, the first 9104 aircraft used for test flights fell down just after the test flight.

It was simply that when the test flight was in a place with few people, and it did not carry too much fuel, the plane fell and did not break it.

"Is there any problem with the pilot's operation?" Liu Yijiu asked with a frown while quickly heading into the assembly workshop in Area 1.

But I kept thinking about the places he designed would cause problems with the helicopter.

"I asked many times and it turned out that the test pilot of our Z7 aircraft was very experienced. There was no problem when operating. There was no problem with the various alarm indicators in front of them..." Liao Zhuojing said with a frown.

It is actually very normal for such a thing to happen.

After all, their helicopters took too short a time from design to test flight. If there was a problem, just find out the problem and correct it.

But what made them collapsed was that they couldn't find the problem at all

"There is no such strange thing. If there is no abnormality, the plane cannot fall off like this. Is there no problem with the spiral? Is it cracked? The hub is not broken? The engine has not ceased?" Liu Yijiu asked a series of questions.

Liao Zhuojing and others shook their heads and said there was no problem.

Liu Yijiu was also confused, "When falling down, it will definitely be reflected on the propeller first. Only when it is reflected on the propeller will it fall down directly..."

If the propeller is rotating all the time, as long as the hub and the coupling are not broken and the connection between the propeller and the aircraft body is not broken, then the helicopter will not be able to fall down.

The helicopter originally provides lift through the huge force of the rotation of the propeller, while the small propeller rotating at the tail provides the aircraft with torque that controls the direction...

Now they told Liu Yijiu that no abnormalities of the helicopter appeared and fell down just like that. Who can believe it?

There must be something wrong.

"I want to meet the test pilot. Send someone to notify him next to the wreckage of the helicopter..." When he arrived in the test workshop, he checked the black box and found that the various data recorded in it were normal, and Liu Yijiu felt even more strange.

He won't believe there is no problem at all

No problem, helicopter won't fall

The wreckage of the helicopter has been on the hillside next to Area 1, because there was no problem and it was also relatively secret here, so they did not move until Liu Yijiu came back.

Even Liao Zhuojing and others did not find the problem, and others could not find it even more. They could only hope that Liu Yijiu could find out the problem after he came back.

The design of the 91 aircraft uses many techniques of the Mi24 female deer. Liu Yijiu improved this. The appearance is much larger than that of the Mi24, especially the tail slurry at the back. It is directly a brand new design, which wraps the rudder in the middle of the tail inclined beam...

Of course, the entire appearance design is actually the enlarged version of Mi24. There are differences in details. If you don’t look at it carefully, you really can’t see it.

The biggest difference is that the propeller of the 91 does not use a single suspense system like Mi24, but uses an articulated dual rotor of a heavy helicopter, thereby providing greater lift.

Therefore, the helicopter wreckage on the ground looks very large.

"Tell me about the process from the beginning of takeoff to the present, especially the detailed process, any data changes in any place, or the subtle feelings you feel when you control it, it's easy to say it out." Liu Yijiu asked the test pilot Huang Pingyang who arrived here with a calm expression.

Facing this young chief designer, Huang Pingyang was not impatient, although he had said all the details many times.

He knew that this was something that cost tens of millions of dollars to study, especially the materials or other things on the helicopter, and even the skin on the shell, were the most advanced things in the base.

It's not possible to measure it with money.

If the reason is not found, the project will basically be scrapped

"...When we reached 20 meters, the plane trembled slightly, checked all the instruments, and did not see the alarm, and the speed of the propeller did not change. I thought my hands were unstable..." Huang Pingyang repeated the words he didn't even have to think.

As a test pilot, he knew that any abnormality might be where the problem exists.

Anyone who is not careful may waste a lot of manpower and material resources...

"Stop, it's here after this. How many seconds did the helicopter fall down?" Liu Yijiu interrupted Huang Pingyang's words. To be continued.
