Chapter 871 Model Blowout Period

Surprise, it was indeed a surprise.

But the WS-10 was tested on an aerial platform about three years ago.

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

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

"Why don't you go inside the cabin and take a look?"

the latter inquired.

Chang Haonan hesitated:

"Forget it. There will be plenty of time later. Let's go to the finalization and appraisal meeting first..."

Yanliang is the only national-level flight certification and test institution in China. All aviation-related products must go through the process here at least once.

It was fine in the past few years when there were fewer projects, but recently, with more and more work coming from the aviation industry system, the scheduling of various facilities and equipment has become a bit tight.

Even meeting rooms are included.

Sometimes we even have to rehearse three shows a day.

Therefore, it is best not to waste time.

……

Although the historical and current relationship between the air 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.

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

Anyone who has worked for the second party knows that before handing over the finished product to the first party, they must first test it according to the same standards or even more stringent standards.

The same is true for WS-10.

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

Only this time, the person in charge changed from the technicians of the aviation power system to the 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 need to be repeated.

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

If I had to do all of this again, I wouldn't have anything else to do for the next year.

Therefore, when the factory conducted previous tests, military representatives were already deeply involved.

Just go through the administrative process and make a confirmation of the result at that time.

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

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 coordinating and psychological role.

Furthermore, the research and development process of the WS-10 was smooth sailing, and everyone involved in it felt this.

Therefore, the overall atmosphere of this work meeting was quite relaxed.

And unlike most similar meetings, it did not drag on for several hours.

In the end, only Chang Haonan, Hai Yide and several representatives from the General Armament Department stayed a little longer to serve as the miserable signing machines.

"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 twenty centimeters high.

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

“You get used to it after signing so many times.”

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

"No one has said no, but we seem to be more accustomed 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:

"It gives people the impression that your handwriting is so bad that you can't show it to others."

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

As they were 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 sealed it.

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

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

In fact, this is not surprising.

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

Hearing his name, Chang Haonan turned around and quickly recognized a slightly familiar face in the crowd.

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

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

A few years ago, Chang Haonan met the other party once.

Also in Yanliang.

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

However, relatively speaking, it was Liu Hongbo who dealt with them more.

It’s a pity that the latter is not a member of the WS-10 R&D team, so he does not appear here.

"Boss Guo, is there another new model coming for test flight?"

After a simple 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, with the increasing demand for helicopters in various industries in recent years, the investment, funds and resources in this field have gradually increased. In particular, the two collaborations with Eurocopter and Agusta have laid a good foundation for China's helicopter industry.

At least there is no need to answer questions while they are being asked like in the past.

"Correct."

Guo Jingshan signaled the others behind him to go into the meeting room first, while he and Chang Haonan stayed at the door:

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

Chang Haonan asked that question just now purely 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?"

"Uh...that's not the case."

Guo Jingshan waved his hand:

"Specialized armed helicopter models are not a high priority in our planning sequence. After all, the Army Aviation Corps..."

He stopped here.

It would be rude to continue.

However, Chang Haonan also understood what the other party meant.

Dedicated armed helicopters, basically only the Army Aviation is used

The Army, the big brother, has the largest number of personnel and equipment.

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

To put it simply...

poor.

"so it is……"

Chang Haonan was a little confused.

He mostly participates in helicopter-related projects through remote control.

I really don't have a very deep impression.

"It's a Z-12."

Guo Jingshan couldn't suppress the smile:

"It's the one developed in cooperation with Eurocopter. It's called NH90..."

Now I have an impression.

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

Only after being reminded by the other party did I remember that there is a domestic isomer.

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

To be honest, he was still a little shocked.

For a 10-ton helicopter, in order to ensure sufficient maneuverability and power redundancy, it would be best to equip it with a 1400-1800kw turboshaft engine.

But his 1600kw turboshaft is still a piece of cake now...

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 insufficient development of different types of aircraft engines...

Cough cough--

"For joint research and development, a lot of things have already been laid down as a foundation. We made some modifications based on our own needs, but the progress is still faster."

Guo Jingshan obviously saw the reason why Chang Haonan was shocked, so he explained directly:

“动力系统目前是两个方案，民用型号直接用罗罗和透博梅卡研发的RTM322-01/9，军用型号我们换了一套减速装置，暂时搭配和米17同款的TV3-117VM……”

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

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