Chapter 871 Model Blowout Period

Surprise, it was indeed a surprise.

But the WS-10 had been tested in the air about three years ago.

As for this No. 760 test platform, it can only be used after the new model is released.

So, under the leadership of Huang Bingxin, Chang Haonan looked around the plane and prepared to leave.

"Why not go inside the cabin?"

The latter asked.

Chang Haonan hesitated:

"Forget it, there will be plenty of time in the future, let's go to the finalization appraisal meeting first..."

As the only national-level appraisal and test flight institution in China, all products related to aviation need to go through the process here at least once.

It was okay when there were fewer projects in the past few years, but recently, with the increasing number of projects in the aviation industry system, the scheduling of various facilities and equipment has become a bit tight.

Even including conference rooms.

Sometimes there are even three sessions a day.

Therefore, it is better not to waste time.

...

Although the historical and current relationship between the aviation force and the aviation industry system is quite complicated, at least at the project level, the two parties are still the identities of Party A and Party B respectively.

To put it bluntly, the design finalization and appraisal is equivalent to Party A conducting a comprehensive assessment of the performance of Party B's product to verify whether it has the performance promised when the project was first established.

Those who have worked for Party B know 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 WS-10.

Therefore, the subjects involved in the finalization and appraisal process have basically been done during the research and development process.

It's just that this time, the leader changed from the technicians of the aviation power system to the representatives sent by the General Armament Department.

Of course, there are thousands of tests involved in the entire project cycle, and not all of them have to be repeated-

For example, the basic test combination of eight major items, about 70 minor items, and thousands of test points of engine basic performance, thrust transient, steady-state and transitional state functions, intake distortion, air starting, on-off afterburner and windmill rotation.

If all of these are done again, there will be no need to do anything else in the next year.

Therefore, when the factory conducted the test before, the military representative was already deeply involved.

Just go through the administrative process and make a determination of the results at that time.

From this perspective, the design finalization and appraisal actually started not from the day before, but from the day the project was established.

In short, although Chang Haonan needs to follow the whole test process, there is not much specific work for him to handle.

It is more of a coordination and psychological stabilizer.

Besides, the development process of WS-10 can be said to be smooth sailing, which is something that everyone involved has felt.

So the overall atmosphere of this work meeting is quite relaxed.

And it is not like most similar meetings, which start with a delay of several hours.

In the end, only Chang Haonan, Hai Yide, and several representatives of the General Armament Department stayed for a while longer, as a miserable signing machine.

"I think I signed more today than in the past year combined."

Chang Haonan put down the pen, rubbing his sore wrist, and complained about the pile of documents next to him that was 20 centimeters high.

Hai Yide next to him was obviously much more experienced in this regard:

"I've gotten used to it after signing so many times."

"I feel like I need to find time to get a seal... It should be equivalent to a signature, right?"

"No one has said no, but we seem to be used to signing directly."

"How should I put it? Using a seal gives people a feeling of..."

At this point, Hai Yide paused for a moment and organized his words:

"Gives people a feeling that your handwriting is so bad that it's embarrassing."

"I don't care about that..."

While talking, several people had 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 sealed it.

At the same time, people who were going to the next meeting had already appeared outside the conference room door one after another.

Just when everyone was about to give up their seats directly, someone suddenly called Chang Haonan.

In fact, this was not strange.

Chang Haonan's face, at least in the circle of chief designers of aviation system models, is still quite recognizable.

After hearing his name, Chang Haonan turned around and quickly recognized a slightly familiar face from the crowd.

"You are... Guo Jingshan, Mr. Guo?"

Guo Jingshan, the chief engineer of Bingfei Group responsible for the development of Z-9.

A few years ago, Chang Haonan had met him once.

Also in Yanliang.

The several helicopter models currently promoted by Bingfei have more or less the participation of Torch Group.

However, relatively speaking, it is Liu Hongbo who deals with them more.

It's a pity that the latter is not a member of the WS-10 development team, so he did not appear here.

"Mr. Guo, is there another new model to be tested for identification?"

After a simple greeting, Chang Haonan asked casually.

The last time the two met because of Z-9, the Flight Test Institute did not even have a complete set of flight test standards for helicopters.

However, with the increasing demand for helicopters in various industries in recent years, the investment, funds and resources in this field have also gradually increased, especially the two cooperations with Eurocopter Group and Agusta, which have laid a good foundation for China's helicopter industry.

At least there is no need to answer questions while asking questions like in the past.

"Yes."

Guo Jingshan gestured to the others behind him to enter the conference room first, and he and Chang Haonan stayed at the door:

"Would you like to guess which model it is?"

Chang Haonan asked the question just now purely 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 it."

Guo Jingshan waved his hand:

"The priority of the special armed helicopter model is not particularly high in our planning sequence. After all, the Army Aviation..."

He stopped here.

It would be impolite to continue.

But Chang Haonan also understood what the other party meant.

The special armed helicopter basically only has one user, the Army Aviation

And the scale of personnel and equipment of the big brother of the Army is the largest.

Although the amount of funds obtained is not small, not much can be used to update equipment.

In short, it is...

poor.

"So it is..."

Chang Haonan is a little confused.

He participated in most helicopter-related projects by remote control.

He really didn't have a deep impression.

"It's the Z-12."

Guo Jingshan couldn't suppress the corners of his mouth:

"It's the one developed in cooperation with Eurocopter Group, which is called NH90..."

Now he has an impression.

To be honest, the more important role of participating in the development of NH90 in Chang Haonan's mind is that it was the fuse that triggered the quality problems of Japanese companies.

When the other party reminded him, he remembered that there is a domestic isomer.

"The Z-12 model... has entered the finalization test stage?"

To be honest, he was still a little shocked.

For a 10-ton helicopter, if you want to ensure sufficient maneuverability and power redundancy, it is best to adapt a 1400-1800kw turboshaft engine.

But his 1600kw turboshaft is still a pie in the sky...

It seems that the main contradiction in the aviation system today is still the contradiction between the growing demand for high-performance power and the unbalanced and insufficient development of different types of aircraft engines...

Ahem——

"For joint research and development, many things have been laid on the basis. We have made some modifications according to our own needs, but the progress should be faster after all."

Guo Jingshan obviously saw the reason for Chang Haonan's shock, so he explained directly:

"There are currently two plans for the power system. The civilian model directly uses the RTM322-01/9 developed by Rolls-Royce and Turbomeca. For the military model, we have replaced a set of reduction gears and temporarily matched it with the TV3-117VM of the same model as the Mi-17..."

The NH90 on this timeline does not have the many flaws caused by design defects in the previous life. It is normal that it is favored by multiple units at the same time, thus extending to two military and civilian models.

Obviously, the results of Chang Haonan's series of efforts in the past few years finally entered the blowout stage at the turn of this century.
