Chapter 871 Model Blowout Period
Surprise, that was indeed a surprise.
But the 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 waiting for 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 work meeting first..."
Yan Liang, as the only one in China All aviation-related products 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 are included.
Sometimes there are even three shows a day.
Therefore, it is better not to waste time.
……
Although 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.
The design finalization 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 the turbofan 10.
So, the subjects involved in the finalization appraisal process have actually been done in the research and development process.
Only this time, the leader changed from aviation power system technicians to representatives sent by the General Armament Department.
Of course, there are thousands of test contents involved in the entire project cycle, and not all of them must be repeated -
For example, basic engine performance, thrust transient, steady state and transition state Function, intake distortion, mid-air starting, on-off afterburner and windmill rotation are a basic test combination of eight major items, about 70 minor items, and thousands of test points.
If we do all this again, we won’t have to do anything else in the next year.
Therefore, 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 Chang Haonan needs to follow the entire testing process, there is actually not much specific work for him to handle.
It plays more of a role in overall coordination and psychological stabilization.
Furthermore, the development process of Turbofan 10 has been smooth sailing, which is felt by everyone involved.
Therefore, the overall atmosphere of this work meeting was quite relaxed.
And it didn’t start for several hours like most conferences 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 looked at the person next to him. The pile of documents was twenty centimeters high and he complained.
Hai Yide 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 the same. It’s about signing, right?”
“No one said it’s not possible, but we seem to be generally used to signing directly.”
“How can 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 ashamed of it."
"I I don’t care...”
While they were talking, several people had already organized the documents on the table, and then, under the joint witness of both parties, they put them into special file bags and finally affixed the seals.
At the same time, people holding the next meeting have appeared outside the conference room one after another.
Just when everyone was about to give up their place, someone suddenly stopped Chang Haonan.
Actually, 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.
"Are you... Guo Jingshan, Mr. Guo?" Guo Jingshan, the chief engineer of Bingfei Group in charge of Z-9 research and development.
A few years ago, Chang Haonan had an encounter with the other party.
Also in Yan Liang.
Several helicopter models currently being promoted by Bingfei have more or less participation from the Torch Group.
However, relatively speaking, Liu Hongbo is the one who has more dealings with them.
Unfortunately, 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 are going to be tested and tested?"
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 laying a pretty good foundation for China's helicopter industry.
At least there is no need to ask and answer questions at the same time as in the past.
“Yes.”
Guo Jingshan motioned to others behind him to enter the conference room, while he and Chang Haonan stayed at the door:
“Why don’t you guess? Which model? "
Chang Haonan asked the question just out of personal interest. Now that the other party asked this, he was naturally willing to cooperate:
"I remember...Professor Liu showed me a special armed helicopter that you modified based on the Z-9?"
"Uh...that's not the case."
Guo Jingshan He waved his hand:
"The special Wuzhi model does not have a particularly high priority in our planning sequence. After all, the Army Aviation..."
He stopped here.
It would be disrespectful to continue.
But Chang Haonan also understood what the other party meant.
Dedicated to Wuzhi, there is basically only one user, Army Aviation
The big brother of the Army has the largest scale of personnel and equipment.
Although the amount of funds obtained is not large, not much can be used to update equipment.
To put it simply...
Poor.
"So..."
Chang Haonan was a little confused.
In most helicopter-related projects, he participates in remote control.
Really not too impressed.
“It’s Zhi-12.”
Guo Jingshan couldn’t keep his mouth shut:
“It’s the one developed in cooperation with Eurocopter Group. 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.
After being reminded by the other party, I remembered that there is another domestic isomer.
"The model Z12...has entered the final testing stage?"
To be honest, he was still a little shocked.
If a 10-ton helicopter wants to ensure sufficient maneuverability and power redundancy, it is best to be equipped with a 1400-1800kw turboshaft engine.
But his 1,600kw turboshaft is still a piece of cake...
It seems that the main contradiction in today's aviation system is still the growing demand for high-performance power, and the inconsistency between different types of aviation engines. The contradiction between balanced and inadequate development...
Cough cough——
“As for joint research and development, the foundation for many things has been laid, and we have carried out some according to our own needs. Modifications, 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 flaws caused by design flaws in the previous life. It was spotted by multiple units at the same time, which led to two military and civilian models, which is quite normal. .
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.
