Chapter 972 Production Finalization and Future Plans

It must be admitted that Duflo's guess is very close to the truth.

In the process developed by Chang Haonan, it is indeed necessary to immerse the parts to be processed in a neutral salt solution.

In fact, for this step alone, if the workpiece can be flushed with an electro-hydraulic beam coaxial with the laser instead of simply immersing it, the effect will be even better.

It's just that China is indeed backward in the field of micro valve pumps, so in the end, such a miracle method was used.

However, the article that Chang Haonan used to deceive competitors was indeed too effective, and coupled with a little mindset, Duflo missed the most important part of the whole process-

Pulse laser.

Of course, that paper can't be effective forever.

Sooner or later, everyone will find that thermal effect is a dead end.

Moreover, as China gradually begins to apply ultrashort laser processing technology on a large scale, related news cannot be covered up all the time.

But even if that day comes early, the impact will not be great.

The principle of non-thermal processing of lasers is completely different from the common thermal processing in the past.

Changing the continuous laser to pulsed laser in the process is not just about changing the laser, but also involves the updating and development of a series of interaction models and numerical algorithms.

With the help of the system, Chang Haonan spent more than a year to barely complete these tasks.

Not to mention others.

Moreover, when everyone's research is just about to be completed, Chang Haonan can still register several key patents before others.

Unless someone is lucky enough to try out the correct result directly from the countless permutations and combinations of process parameters.

Then Chang Haonan will start to consider whether there is a second person who is also cheating...

...

However, at this moment, Chang Haonan can't take care of the movements of friendly companies.

Because a very important node for him is right in front of him.

"Mr. Chang, this is the situation statement sent by the Arms Equipment Bureau ten minutes ago."

Zhang Liangping said and put an envelope with a note in front of Chang Haonan.

Hearing this unit, the latter quickly moved his eyes away from the computer screen and opened it with the fastest action.

The Arms Equipment Bureau is a second-level unit under the General Armament Department.

Although the rank is not very high, it is responsible for the finalization and appraisal of the equipment of the Navy, Air Force and the Second Artillery.

If it is a non-key model, then the second-level finalization committee will be directly formed by them.

Even if it is a key equipment that requires a first-level finalization committee, a lot of manpower will need to be drawn from it.

In short, it is one of the most critical departments in Party A.

Therefore, although what was sent was an official letter rather than an instruction, it still needs to be treated with priority.

There is a red-headed document in the envelope.

[Our bureau has received feedback from various combat units and flight research institutes on the WS-10 engine. The cumulative installed working time of 36 prototypes and mass-produced machines of the two sub-models has exceeded 10,000 flight hours, with good data records and excellent trial evaluations. The military representatives stationed in the factory have a clear understanding of the production process and have confirmed that the process meets the standards...]

[...]

[Based on the above, our bureau believes that the WS10 engine has passed the troop trial and production finalization tests and is qualified for subsequent assessments. Please organize and submit relevant documents as soon as possible...]

Originally, Chang Haonan was a little worried whether there was any urgent problem that needed to be solved by himself.

The result was great news.

"Good, good, good!"

Looking at the two thin pages in his hand, Chang Haonan said three good words in a row, then looked up at Zhang Liangping:

"Old Zhang, you should immediately draft a notice to the 606th Institute, explain the situation, and tell them to prepare for the process assessment in early February. If everything goes well, it is best to finish it before the Spring Festival!"

To sum up the content of this document, Party A has basically recognized the performance and stability of the WS-10, and said that it can organize production finalization and appraisal-

Compared with design finalization, the current national military standard does not make detailed provisions for the specific process of production finalization.

It only states that production finalization should include organizing process and production conditions assessment, troop trial, production finalization test, and organizing production finalization review and approval.

Generally speaking, the second and third items can be completed in the process of small-scale trial production and delivery.

As mentioned in the document just now.

The relevant documents that the Equipment Bureau requires the Aviation Power Group to submit involve the remaining two contents.

This process does not include a lot of high-risk extreme tests like the design finalization, but mainly some production site and written review work.

It may even seem a bit boring.

But for Chang Haonan and the entire project team, it is the most important milestone.

It means that the technical status of the two models of WS-10A/B has been frozen, and the small-batch trial production can be ended and the mass production stage can be officially entered.

Don't underestimate the difference between these words.

Many equipments may still be in the "small batch" hat until they are retired.

More importantly, after this, Chang Haonan can be truly liberated from the WS-10 project itself and devote his main energy to new challenges.

...

Three weeks passed quickly.

The production of WS-10 was finalized, and everything went smoothly.

It even went so smoothly that it was beyond Chang Haonan's expectations.

The date for the production finalization appraisal and production line acceptance meeting was finally set on February 10, the eve of the Spring Festival.

In fact, it is similar to the graduation defense situation.

When it is decided to hold an appraisal meeting, it means that the project is stable——

Because the project in question simply won’t get to this point.

Of course, even so, Chang Haonan was fully prepared.

Especially when it comes to ultra-short laser processing.

The main reason is that I worry that if I explain it briefly, others will think it is not detailed enough, and if I explain it deeply, others will not understand.

But it turned out that he still thought too much.

Backed by extensive testing and usage data, there's simply no room for flex.

So much so that the speed at which each link is announced as having passed the certification is much faster than the speed at which the corresponding person in charge signs and seals it.

The meeting that was originally planned to last from morning to night actually lasted less than three hours and there was no content...

As a result, the entire venue fell into an embarrassing silence.

All that is left is the rustling sound of the pen tip crossing the page...

In the end, it was Lu Zengwu, who was responsible for the entire stereotype appraisal, who took the lead in breaking the silence:

"Mr. Chang, I saw the process description document you submitted. It says that the maximum annual output is expected to be nearly 200 units?"

For China, the last time it could produce so many engines annually was when it even built a turbojet 6 for the J-6...

"Um……"

Chang Haonan nodded slowly:

"Let's make a conservative estimate... After all, the production type test requires us to submit a lower limit. In fact, there may be more."

"But have you ever considered that most of this production capacity... is likely to be idle?"

After Lu Zengwu finished speaking, he may have felt that this question was a little offensive, so he quickly added:

"This...issues related to production and finalization are completely over. Now it's just my personal curiosity..."

Chang Haonan waved his hand to indicate his understanding:

“Right now, we may indeed not need so much aerospace production capacity, but as an enterprise we must not just look at the present, but must plan for the future in advance.”

"Among other things, the SeA series engines we are currently involved in research and development may account for 20-30 units of production capacity per year in two to three years. As my country's economic development continues to accelerate, the frequency of aviation equipment upgrades will also gradually increase. Increase, and including the backup parts required for overhaul and maintenance, it is not an exaggeration to have a production capacity of 100 units per year..."

"In addition, we expect to launch a turbofan 10 aerospace modification project after the year. The Navy's demand for this model is not small. Calculating this, as long as we add one or two additional businesses, we can fill this 200 million yuan per year. Taiwan’s production capacity may not be enough…”

"..."

After saying this, not only Lu Zengwu, but also many people who were bowing their heads to sign also raised their heads.

"Can we...need...100 engines every year?"

Lu Zengwu's eyes widened and he couldn't even speak very fluently.

Chang Haonan said in his heart: If I tell you that China can produce a total of more than 80 third- and fourth-generation aircraft of various types per year in the future, I am afraid I will scare you out of your wits...

Of course, these words are meant to be complained in the mind and cannot be said out loud.

So, he had to change his approach:

"Everything is possible in the future."

"Director Lu, if you think about it, it doesn't take too long. When the Turbofan 10 project was first established, who could have predicted what would happen five years later..."
