Chapter 871 Model Blowout Period
Surprise, that is indeed a surprise.
But Turbofan 10 had been tested on an aerial platform about three years ago.
As for this No. 760 test platform, it can only be used after the new model.
So, Chang Haonan, led by Huang Bingxin, looked around the plane and prepared to leave.
“Don't you want to take a look inside the cabin?”
The latter asked.
Chang Haonan hesitated for a moment:
“Forget it, there will be plenty of time in the future, let's go to the finalization appraisal meeting now…”
Yanliang is China's only national-level certification and flight test agency. All products related to aviation need to go through the process at least once here.
In the past few years, it was okay when there were few projects. Recently, as more and more work has been done in the aviation industry system integration, the schedule of various facilities and equipment has become a bit tight.
Even meeting rooms.
Sometimes there are even three sessions a day.
Hence, it is best not to waste time.
ˆAlthough the historical and practical relationship between the aviation force and the aviation industry system is quite complicated, at least at the project level, the two parties are still Party A and Party B respectively.
Design appraisal, to put it bluntly, is equivalent to Party A's comprehensive assessment of the performance of Party B's products to verify whether they have the performance promised when the project was originally established.
Everyone who has worked for Party B knows that before handing over the finished product to Party A, they must first test it according to the same standards, or even stricter standards.
The same is true for turbofan 10.
Hence, the subjects involved in the finalization appraisal process have actually been done in the research and development process.
It's just that this time, the leader changed from technicians of the aviation power system to representatives sent by the General Armament Department.
Of course, there are tens of thousands of tests involved in the entire project cycle, and not all of them must be repeated -
For example, the basic performance of the engine, thrust transient, steady state and transition state functions, intake distortion, mid-air starting, on-off afterburner and windmill rotation are a set of eight major items, about 70 minor items, and thousands of test points. Basic test suite.
If you do all these things again, you won't have to do anything else in the next year.
Hence, when the factory conducted tests before, military representatives were already deeply involved.
Just go through the administrative process and make a determination on the results at that time.
From this perspective, the design finalization appraisal actually starts not from the day before, but from the day of project establishment.
In short, although the testing process requires Chang Haonan to follow the entire process, there is actually not much specific work for him to handle.
It serves more of a coordinating role and a psychological anchor.
Furthermore, the development process of Turbofan 10 has been smooth sailing, which is felt by everyone involved.
So the overall atmosphere of this working meeting was quite relaxed.
And it didn't start for several hours like most meetings of the same type.
In the end, only Chang Haonan and Hai Yide, as well as a few representatives of the General Armament Department, stayed for a while longer to serve as signing machines for the hard workers.
“I think I signed more today than in the past year combined.”
Chang Haonan put down the pen, rubbed his sore wrist, and complained while looking at the pile of documents next to him that was 20 centimeters high.
Haiyide next to him is obviously much more experienced in this regard:
“You'll get used to it if you sign too many.”
“I feel like I need to find time to get a seal... It should be equivalent to a signature, right?”
“No one said no, but we seem to be used to signing directly.”
“How should I put it, using a seal will give people a sense of...”
At this point, Haiyide paused for a moment and organized his words:
“It gives people the impression that your handwriting is so poor that you are not visible to others.”
“I don't care about that…”
While talking, several people had already sorted out the documents on the table, and then, under the joint witness of both parties, they put them into a special file bag and finally affixed the seal.
At the same time, people holding the next meeting have already appeared outside the conference room door one after another.
Just when everyone was about to give up the place, someone suddenly called Chang Haonan.
In fact, this is not surprising.
Chang Haonan's face is quite recognizable, at least in the circle of aviation system model chief engineers.
Chang Haonan turned around when he heard his name and quickly recognized a slightly familiar face in the crowd.
“You are...Guo Jingshan, Mr. Guo?” Guo Jingshan, the chief engineer of Bingfei Group in charge of Zhi-9 research and development.
A few years ago, Chang Haonan had an encounter with the other party.
also in Yanliang.
Several helicopter models currently being promoted by Bingfei have more or less participation from Torch Group.
However, relatively speaking, Liu Hongbo is the one who has more dealings with them.
It's a pity that the latter is not a member of the Turbofan 10 R&D team, so he does not appear here.
“Mr. Guo, are there any new models that need to be tested for certification?”
After a brief greeting, Chang Haonan asked casually.
The last time the two met because of the Z-9, the Flight Test Institute did not even have a complete set of flight test standards for helicopters.
However, as the demand for helicopters in various industries has increased in recent years, the investment, funds and resources in this field have gradually increased, especially the two cooperations with Eurocopter and AgustaWestland, which can be regarded as helicopters for China. Industry has laid a pretty good foundation.
At least there is no need to ask and answer questions at the same time as in the past.
"right."
Guo Jingshan motioned to the others behind him to go into the conference room, while he and Chang Haonan stayed at the door:
“Would you like to guess which model it is?”
Chang Haonan asked the question just out of personal interest. Now that the other party asked this question, he was naturally willing to cooperate:
“I remember...Professor Liu showed me a special armed helicopter that you modified based on the Z-9?”
“Well...that's not the case.”
Guo Jingshan waved his hand:
“The dedicated Wuzhi model does not have a particularly high priority in our planning sequence. After all, the Army Aviation…”
He stopped when he said this.
It would be impolite to continue.
However, Chang Haonan also understood what the other party meant.
Dedicated to Wuzhi, basically only one user is Army Airlines
The big brother of the army has the largest personnel and equipment.
Although the amount of funds obtained is not large, not much can be used to update equipment.
Simply put it is…
poverty.
"so it is…"
Chang Haonan can't think of anything.
In most helicopter-related projects, he participates in remote control.
I'm really not too impressed.
ification
Guo Jingshan couldn't hold his lips down at all:
“It's the one developed in cooperation with Eurocopter. It's called NH90 over there…”
Now I have an impression.
To be honest, participating in the research and development of NH90, the more important role in Chang Haonan's heart is that it was the fuse that detonated the quality problems of Japanese companies.
When the other party reminded me, I remembered that there was also a domestic isomer.
“The Z12 model...has entered the final testing stage?”
To be honest, he was still a little shocked.
To ensure sufficient maneuverability and power redundancy, a 10-ton helicopter needs to be equipped with a 1400-1800kw turboshaft engine.
But his 1600kw turbine shaft is still a piece of cake...
It seems that the main contradiction in today's aviation system is still the contradiction between the growing demand for high-performance power and the unbalanced and inadequate development of different types of aviation engines...
Ahem—
“As for joint research and development, the foundation for many things has been laid. We have made some modifications according to our own needs, but the progress is still faster.”
Guo Jingshan obviously saw the reason for Chang Haonan's shock, so he explained directly:
"There are currently two options for the power system. The civilian model directly uses the RTM322-01/9 developed by Rolls-Royce and Turbomeca. For the military model, we changed a set of reduction gears and temporarily paired it with the TV3-117VM, which is the same model as the Mi 17... "
The NH90 in this timeline does not have many shortcomings caused by design flaws in the previous generation. It is also very normal that multiple units have taken a fancy to it at the same time, thus leading to both military and civilian models.
Obviously, the results of Chang Haonan's series of efforts in the past few years finally entered a blowout stage at the turn of this century.
