Chapter 488 Preparing for drones
For Rolls-Royce, the M250 is just an unexpected bonus they received when they acquired Acheson.
The basic design of this engine was completed as early as the 1960s, and it had been transferred to several countries for license production during the Acheson period.
Although the update cycle of turboshaft and turboprop engines is not fast, and this model is not obsolete until the 1990s, this gadget with a maximum output of only 331kW is not a core technology in any case.
The current bid from China is quite reasonable, and it is a market with huge potential. Rolls-Royce made the right choice within a few days.
Taking into account the previous experiences and lessons, George and Adam no longer dared 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.
They specially added a clause in the contract:
In China, this model can be used in any way, but if it is sold to a third country, a special export license fee must be paid to Rolls-Royce for each transaction.
I can only say that it is a big company with rich experience.
In fact, this is the template of Rolls-Royce's technology licensing contract, which is a must for any authorized object.
Since the default fee ratio is really not high, neither Rolls-Royce headquarters, George and Adam, nor Ren Bingda from China took it seriously when signing the contract.
Before the formal negotiations, Ren Bingda had already reported his ideas to Chang Haonan through Zhang Zhenhua.
No one thought that this clause would actually come into play one day.
Chang Haonan stretched out his hand and pressed down in mid-air, signaling the other party to relax:
“Model development is not about blindly pursuing the superiority of paper data, but should comprehensively consider the entire aerodynamic system and strive to build a complete aeroengine model spectrum from low to high.”
This is a light turbine with numerous sub-models, and its targets are determined to be the B17 turboprop model of the M250 II series, and the C10 turboshaft model of the same II series.
Although the 300kW level was personally decided by Chang Haonan when the two met last time, in the process of technology introduction, there are many leaders who can't move when they see advanced models, so it is safer to explain a few more words.
But reputation and power are two different things after all.
Looking at Zhang Zhenhua's cautious look, Chang Haonan sighed secretly in his heart.
In fact, the latter himself did not have too in-depth research on the type spectrum of this type of light aviation engine, so he took the information sent by Zhang Zhenhua and read it for a long time.
Today's Chang Haonan is already quite extraordinary just because of his real identity.
Zhang Zhenhua saw that Chang Haonan had reached the key point and quickly opened his mouth to explain:
“Although the III series and IV series are advanced, Rolls-Royce may not be willing to transfer technology, and the price must be high.”
However, not too many years later, Rolls-Royce will thank its predecessors who set this template.
“From this perspective, your group's choice is not wrong.”
“M250 series engines…”
Obviously, he was worried that Chang Haonan would be dissatisfied with the model selection.
“Mr. Chang, the II series is the most balanced choice for General Manager Ren and them in terms of cost, technical difficulty and performance after comprehensive consideration.”
“Also, the turboshaft of the C30 series overlaps with the turboshaft 8 that our country has introduced a complete set of technology from France, and it does not meet the 300kw power level you previously requested.”
Let's go back to Shengjing.
Even though the two met for the first time at the end of last year, the latter already had a fairly high reputation in the aviation industry system.
“Don't worry, I understand.”
Both models use the same 6-stage axial flow + 1-stage centrifugal compressor. The maximum output power is adjustable between 294-331kw according to different lifespans.
Although Torch Group is small in scale, it is also a second-level state-owned enterprise directly under the Academy of Sciences. Its level is on the same level as Haojing Engine Group and Shengjing Aircraft Industry Group, which have thousands of employees.
As the general manager of Torch Group, if Chang Haonan insists on rank, he can even hold a full-time job in the department.
It's just that because he is too young and the de-administration of state-owned enterprises is being promoted, he is regarded as a low-ranking employee and has not yet been officially promoted.
But the authority in his hands cannot be compromised at all.
Not to mention that as the chief designer of the Turbofan 10 project, it is no exaggeration to say that he can directly mobilize the resources of half the aviation industry system.
As for the personal connections with which I can speak directly to the Science and Technology Committee and the Science and Technology Committee, it is even more frightening.
Ding Gaoheng and Song Jian behaved like two ordinary amiable little old men when facing Chang Haonan, but it does not mean that they behave like this in front of others.
Most people have no chance of talking to them directly.
In short, the accumulation of many identities has actually given Chang Haonan's words and deeds a considerable influence.
This is especially true for middle-level leaders in the aviation industry system like Zhang Zhenhua.
Many times, Chang Haonan's unintentional words or even a tone of voice can determine a project or a person's future and destiny.
So, he had to start paying attention to his words and deeds.
Especially in front of these subordinates.
Whether Chang Haonan likes this is not necessarily true. But whether he likes it or not, this is what happens.
After receiving a clear positive evaluation, Zhang Zhenhua finally felt relieved.
So he tentatively asked about another thing -
Although Ren Bingda did not say it clearly, he still hoped that Chang Haonan could guarantee the prospects of such an engine.
Although part of the funds from Turbofan 9 was diverted to other uses, although it was approved by the group leaders and there was no procedural problem, if the money was really wasted, Ren Bingda, as the initiator, would also be subject to some punishment. Some negative effects.
The basic logic on China's side is to unify powers and responsibilities. After all, this is a large amount of foreign exchange expenditure. It is impossible to completely select responsibilities just because of procedural compliance.
“Lao Zhang, I have made it clear before.”
Chang Haonan's tone became slightly more serious:
“The models introduced this time cannot be preset for installation, so I can't guarantee anything here.”
He has a big chess game to play, so naturally he can't agree to it directly—
The reason why we introduced such an inconspicuous model through Ciro Company is to prove the feasibility of the "aviation-engine first" route.
And if you give a large number of models to a few models before the official introduction, you will be on the old path of "model traction" in the past.
Even on the contrary, it proves that the path of model traction is correct.
Wouldn't that be just shooting yourself in the foot?
Seeing Chang Haonan's determined look, Zhang Zhenhua did not dare to continue to struggle with this matter.
He quickly changed the topic to turbofan 9A, reported on the installation progress during this period, and then left the former's office.
After seeing off Lao Zhang, Chang Haonan sighed softly, and after a moment of hesitation, he picked up the receiver of the red phone next to him.
Although he said something tough, it was impossible for him to really ignore it.
This model was introduced by him at his suggestion to the Haofa Group. If he just acted as a hands-off shopkeeper, wouldn't it be like starting with chaos and eventually abandoning it?
After several transfers, the call was finally connected.
Opposite him is Sun Huizhong, an old acquaintance of Chang Haonan who has been promoted to the chief designer of Guihang Industry.
“Sun Gong, it's me, Chang Haonan.”
Chang Haonan rarely used this phone number, so he had to report his home address first.
“Mr. Chang?”
The person on the phone was a little confused at first, and then quickly turned into surprise:
“Mr. Chang, what are your instructions for calling us? We will implement them immediately!”
If people like Zhang Zhenhua and Zhong Shihong are just grateful and respectful to Chang Haonan, then the comrades in Guizhou Province are completely worshiping him.
After all, when Guizhou Aviation Industry was almost desperate, it was Chang Haonan who injected them with a life-saving research fund in the name of a "Project 10 DSI Technology Demonstration Machine".
The Instructor 9, which is currently undergoing intensive ground tests and preparations for flight tests, was almost designed by Chang Haonan and Sun Huizhong.
Unsurprisingly, 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 wonder if Mr. Sun still remembers it?”
The M250 engine is mainly installed on three types of aircraft—light helicopters, primary trainers or medium-sized unmanned aerial vehicles.
For the current aviation industry, the last one is obviously easier to implement and more practical.
Even if PLA has no spare money for equipment, it can still export it.
“I have an impression, of course I have an impression!”
Even though there was a phone line between them, Sun Huizhong stood up:
"It's just that our group's strength is concentrated on key research coaches 9. Therefore, currently we have only established a UAV flight control research laboratory in accordance with your previous instructions, recruited a group of graduates in related majors, and are doing preliminary planning. research."
“I wonder if Mr. Chang needs us to adjust the focus of R&D?”
Facing such a positive Sun Huizhong, Chang Haonan quickly replied:
“No, no, no, that's not necessary. You should focus on completing the Coach 9 first. Its test flight data is related to the design of the subsequent prototype of the J-10, and progress must be ensured.”
"I just want to tell you that I have a 300kW light turboprop engine here that can be used as power. I will fax the more detailed data in a while. You can use this power data as a reference during the pre-research process. to determine the size of the aircraft and other data.”
This is definitely an unexpected surprise for Sun Huizhong.
After all, almost every model of China Aviation Industry has been worried about the engine.
It is indeed rare that the engine is predetermined before the aircraft is even made.
“Okay…okay!”
