For Rolls-Royce, the M250 was just a windfall when they bought Acheson.

The basic design of the engine was completed as early as the 1960s, and during the Acheson period it was transferred to several countries for licensed production.

Although the turboshaft and turboprop engine update cycle is not fast, and this model is not obsolete until the current 90s, this gadget with a maximum output of 331kW is not a core technology in any way.

Now that Huaxia's bid is reasonable, and it is a market with huge potential, Rolls-Royce made the right choice in a few days.

Considering the lessons learned, George and Adam did not dare to mention anything that was discussed once a year, but honestly signed a three-year technology transfer contract.

Of course, the British are not philanthropists either.

They specifically added a clause to the contract:

In China, this model can be used in any way, but if it is to be sold to a third country, then a special export license fee must be paid to Rolls-Royce for each transaction.

It can only be said that in the end, it is a large company with a lot of experience.

In fact, this is the template of Rolls-Royce's technology licensing contract, which is one for any authorized object.

Because the default fee ratio is really not high, whether it is Rolls-Royce's headquarters, George and Adam, or Ren Bingda on the Huaxia side, they actually didn't take it seriously when they signed the contract.

No one thought that this clause would really work one day.

However, not too many years later, Rolls-Royce will thank the predecessors who set this template back then.

……

Let's go back to Shengjing's side.

Before the formal negotiations, Ren Bingda had already reported his ideas to Chang Haonan through Zhang Zhenhua.

"M250 Series Engine ......"

In fact, the latter himself did not have too in-depth research on the type spectrum of this kind of light aviation hair, so he took the information sent by Zhang Zhenhua and read it for a while.

This is a lightweight turbine with many sub-models, and the target for pickaxes is the B17 turboprop model of the M250 II series and the C10 turboshaft model, which is also the II series.

Both models use the same 6-stage axial + 1-stage centrifugal compressor, and the maximum output power is adjustable between 294-331kW depending on the life.

"Mr. Chang, the II series is the most balanced choice in terms of cost, technical difficulty and performance after comprehensive consideration."

Zhang Zhenhua saw Chang Haonan turn to the key point, and hurriedly explained:

"Although the III series and IV series are advanced, Rolls-Royce may not be willing to transfer technology, and the asking price must be very high."

"In addition, the turboshaft of the C30 series coincides with the turboshaft 8 that our country has introduced a full set of technology from France, and it does not meet the 300kw power level you previously require."

Obviously, he was worried that Chang Haonan would be dissatisfied with the choice of model.

Although the 300kw level was set by the two last time they met, Chang Haonan personally set it, but in the process of technology introduction, leaders who can't walk when they see advanced models abound, and it is safer to explain two more sentences.

"Don't worry, I understand."

Chang Haonan stretched out his hand and pressed down in mid-air, signaling the other party to relax:

"Model development is not a blind pursuit of paper data, but should comprehensively consider the entire aero power system, and strive to build a complete aero engine spectrum from low to high."

"From this point of view, your group's choice is not wrong."

Seeing Zhang Zhenhua show a cautious look, Chang Haonan secretly sighed in his heart.

Although when the two first met at the end of last year, the latter already had a high reputation in the aviation industry system.

But prestige and power, after all, are two different things.

Today's Chang Haonan is quite unusual.

Although the scale of the Torch Group is very small, it is also a second-level state-owned enterprise directly under the Academy of Sciences, and its level is on an equal footing with the behemoths of tens of thousands of employees, such as Hojing Engine Group and Shengjing Aircraft Industry Group.

As the general manager of the Torch Group, Chang Haonan can even be qualified for the main position of the boss if he insists on the level.

It's just that because he is too young and is promoting the de-administration of state-owned enterprises, he is considered a low-level high-level job, and he has not yet been officially promoted.

But the power in his hand is not discounted at all.

Not to mention that as the chief designer of the turbofan-10 project, it is not an exaggeration to say that he can directly mobilize the resources of half of the aviation industry system.

As for the connections between the Commission of Science and Technology and the Commission of Science and Technology that can speak directly, it is even more terrifying.

When Ding Gaoheng and Song Jian faced Chang Haonan, they behaved like two ordinary kind little old men, but it didn't mean that they were like this in front of others.

Most people simply don't have the opportunity to talk to them directly.

In short, the superposition of many identities has actually made Chang Haonan's words and deeds have considerable influence.

This is especially true for middle-level leaders like Zhang Zhenhua and the aviation industry system.

Many times, Chang Haonan's unintentional words, or even a tone, can determine a project, or a person's future and destiny.

Therefore, he also had to start paying attention to his words and deeds.

Especially in front of these subordinates.

If you want to say whether Chang Haonan likes this, it may not be.

But whether he likes it or not, that's what happened.

And after getting a clear positive evaluation, Zhang Zhenhua finally put his mind at ease.

So I tentatively asked about another thing—

Although Ren Bingda did not say it explicitly, the meaning of his words was to hope that Chang Haonan could guarantee the prospect of such an engine.

Although it was approved by the group leaders and there was no problem in the procedure for diverting part of the funds of the turbofan 9 for other purposes, if the money was really wasted, then Ren Bingda, as the initiator, would also be somewhat negatively affected.

The basic logic of Huaxia's side is the unity of power and responsibility, which is a large amount of foreign exchange expenditure after all, and it is impossible to completely select the responsibility just because of procedural compliance.

"Lao Zhang, I have made this matter clear before."

Chang Haonan's tone became slightly serious:

"For the time being, there is no way to preset the installation target for the model introduced this time, so I can't guarantee anything here."

He still has a big game of chess to play here, so naturally it is impossible to directly agree to it-

The reason why such an inconspicuous model was introduced through Xiluo Company was to prove the feasibility of the route of "aviation first".

And if a few models are given before the official introduction, it will be on the old road of "model traction" in the past.

It even proved that the model traction was the right way.

Wouldn't that be a shot in the foot?

Seeing Chang Haonan looking so determined, Zhang Zhenhua didn't dare to continue to dwell on this matter.

He quickly shifted the topic to the turbofan 9A, reported on the installation progress during this time, and then left the former's office.

After sending Lao Zhang away, Chang Haonan sighed softly, and after hesitating for a moment, he still picked up the receiver of the red phone next to him.

Although he said it strongly, he couldn't really ignore it completely.

This model was introduced by him at the suggestion of the Pickaxe Group, if it was just a hands-off shopkeeper, wouldn't it be a mess and an end of abandonment?

After a few transfers, the call was finally connected.

On the other side is also Chang Haonan's old acquaintance, Sun Huizhong, who has been promoted to the chief designer of Guihang Industry.

"Sun Gong, it's me, Chang Haonan."

Chang Haonan rarely uses this phone, so he first has to report to his home.

"Mr. Chang?"

The phone was a little dazed at first, and then quickly turned into surprise:

"Mr. Chang, what are your instructions for calling? We'll do it right away! ”

If Zhang Zhenhua and Zhong Shihong are only grateful and respectful to Chang Haonan, then the comrades in Guizhou Province are completely worshipped.

After all, when Guihang Industry was almost cornered, it was Chang Haonan who injected a life-saving research fund into them in the name of a "No. 10 Project DSI Technology Verification Machine".

And the Coach 9, which is currently in full swing for ground tests and preparations for test flights, was almost designed by Chang Haonan with Sun Huizhong.

If nothing else, this will be the flagship model of Guihang Group for a long time to come.

"I can't talk about it, I just want to ask, at the beginning of this year, I should have mentioned to you about a medium-altitude long-endurance drone, I don't know if Sun Gong still has an impression?"

The M250 engine is mainly installed for three types of aircraft - light helicopters, primary trainers or medium-sized UAVs.

For the aviation industry at the moment, it is clear that the last one is easier to achieve and more practical.

Even if the PLA has no spare money for equipment for the time being, it can be exported.

"There is an impression, of course there is an impression!"

Despite being separated by a telephone line, Sun Huizhong stood up:

"It's just that the strength of our group is focused on tackling key problems on the coach 9, so at present, we are only following your previous instructions to set up a UAV flight control research room, recruiting a group of graduates from related majors, and doing preliminary research."

"I wonder if Mr. Chang needs us to adjust the focus of R&D?"

Faced with such a positive Sun Huizhong, Chang Haonan hurriedly replied:

"No, no, no, that's not necessary, you still have to concentrate on doing a good job of the Coach 9 at present, its test flight data is related to the design of the follow-up prototype of the J-10, and the progress must be guaranteed."

"I just want to tell you, I have a 300kw light turboprop engine here that can be used as power, and I will fax more detailed data later, and you can use this power data as a reference to determine the size of the aircraft and other data during the pre-research process."

This was definitely a surprise for Sun Huizhong.

After all, almost every model of Huaxia Aviation Industry has worried about engines.

It is indeed rare for an aircraft like this to be given before the engine is given.

"Good...... Good! ”
