Chapter 517 Turboprop 7 and Turboshaft 7

Chang Haonan did not follow the entire testing process of Turbofan 9A.

After all, he is the chief designer of Turbofan 10, so he only needs to focus on some key testing links involving new technologies.

As for the rest of the matter, comrades from Haojing will naturally be responsible for handling it.

In any case, the Turbofan 9 is, after all, a Haofa Group model on paper.

What surprised Chang Haonan was that the other party directly sent a whole team over.

Of course, this is an internal matter within someone else's company. He only needs to be responsible for handing over the work.

"Hello, comrade."

Chang Haonan shook hands with the team leader opposite him in a routine manner, then waved his hand and motioned to the staff behind him to put the relevant documents on the table:

"This is a work plan list, these three are performance comparison reports before and after improvements, these are the work schedules that have been completed so far, these are some minor problems that have been discovered so far, and these..."

In the past month, almost half of the Turbofan 9 test project has been completed, so the files on the table have almost piled up into a mountain.

The Haofa Group should have set up responsible persons for different subsystems. In short, several people on the other side signed together, and it took almost an hour to get everything done.

After the handover ceremony.

Chang Haonan's flight was scheduled for the next day, and he originally planned to have a meal and then go back to rest.

But just when he was about to leave, the team leader from Haofa came over specifically.

"Mr. Chang, I am the deputy general manager of Haojing Engine Group, Ren Bingda."

The other party said as he took out a business card.

"Ren Bingda..."

Chang Haonan was originally prepared to just deal with it with a few words and then pass.

But the name felt familiar to him.

Therefore, Chang Haonan slowed down, let the other party follow him, and took the business card and took a look at it.

After a moment of recollection, he quickly remembered that he seemed to have seen this name in a report a few months ago.

"Oh...you are in charge of the business of Siro Group..."

Seeing that Chang Haonan still remembered him, Ren Bingda was overjoyed and nodded quickly:

"Yes, it's me. When I decided on the future cooperation method with Rolls-Royce Group last year, I submitted a report to you through Minister Zhang Zhenhua."

"However, this is the first time I have the honor to communicate with you face to face."

When the other party described it like this, Chang Haonan remembered the complete ins and outs.

"Oh, yes, that is indeed the case. I remember that in the end you reached an agreement with Rolls-Royce and introduced an M250 light engine, right?"

"Yes, this project has been negotiated now, thanks to your guidance and help. I am looking for you this time to report on this matter..."

Ren Bingda came to Chang Haonan specifically, and the core purpose was of course to get closer to him.

The latter is now a popular figure within the Commission of Science, Technology and Industry for National Defense, and judging from organizational relationships, he is probably also highly regarded by the Commission of Science and Technology.

Even if it is now difficult to truly become a confidant, even if you just let the other person remember your name, it may be useful at some point in the future.

However, building relationships is also a test of one's skills.

If you can't find any topic that both parties are interested in as a reason, then it can only be regarded as a greeting.

And if you insist on finding something to talk about, it will easily have the opposite effect.

Because of this, Ren Bingda specifically brought the topic to the cooperation with Rolls-Royce.

He also specifically used the name "report".

Although there is no organizational affiliation between him and Chang Haonan.

As expected, the latter became interested in this:

"It's settled...that means we are already preparing to digest and absorb related technologies?"

This is almost the question Ren Bingda wants to hear most.

The point of currying favor with others is nothing more than "catching up to others."

There is no unified standard for this "good", but rather a specific analysis based on specific objects.

Although it was the first time for Ren Bingda to meet Chang Haonan in person, he had already analyzed that the other person liked an efficient way of working.

So he quickly replied:

"We have made some concessions in terms of cost and asked Rolls-Royce to speed up the progress. We are currently debugging the production line and preparing to produce the first batch of engines through assembly with supplied materials."

"It is expected that this batch of products will be offline in March to April, and the localization rate will be increased to 100 within two years..."

"According to regulations, this kind of domestically produced engine must have its own name. After our communication, we reused the two names that had been planned before but had only reached the drawing stage, Turboprop 7 and Turboshaft 7. …”

"..."

The content of Ren Bingda's report indeed made Chang Haonan quite satisfied.

In terms of technical difficulty alone, the M250 is not an aircraft engine model with high manufacturing thresholds.

Otherwise, there would not be production lines in more than a dozen countries.

Even for China Aviation Industry, which is still in the development stage, if it really concentrates its efforts, it will not be difficult to come up with such a lightweight product.

It's just that his energy is limited, so he can only focus on the big and let go of the small on specific projects.

To go to war for such a model, the cost-efficiency ratio is really too low.

This is why the M250 has no rivals at the same level.

Everyone feels that it would be a waste to develop it from scratch.

The British are selling production lines everywhere again.

Eventually, the same model with different names was produced all over the world.

In short, achieving national production in two years is by no means a satellite launch even for the Haofa Group with poor technical strength.

"Are there any confirmed users now?"

Chang Haonan naturally found the basis for this model, which is Guihang's long-endurance drone that imitates the Predator, and the new junior trainer aircraft that will replace the Chujiao 6 in the future.

However, it would be great if Haofa Group could find a way out on its own.

"We have been talking about this aspect, but now it has been confirmed that only the Hongdu Group will use this model on the improved Agricultural 5 aircraft."

Speaking of this, Ren Bingda showed some worry.

In fact, although only one confirmed user has been discussed so far, after his research during this period, he found that many trainer aircraft and training helicopters used by civil aviation schools use this model of power, so there is really no need for it in the market. Worry too much.

The reason why he said this was just because he knew that this topic had come to an end, and before switching to new conversation content, he needed to leave an introduction for the next contact.

This is the same as pursuing a date with a girl.

If you leave half of the topic, it will be easy to use it as an excuse to ask out a second time naturally.

And it will never be cold.

Of course, it is impossible for Chang Haonan to just take over everything and say clearly that I will solve the guarantee problem for you.

He just nodded and replied in an encouraging tone:

"As long as there are initiating users, it is a good thing, which means there is no problem with the power-first approach."

"The potential of the domestic aviation industry has not yet been fully unleashed, and there will definitely be no shortage of market for this kind of light power in the future!"
