Chapter 464: We don't sell heads

"Congratulations on your imitation work. Great progress has been made." When I came to the meeting room again, it was a celebration. The representatives of Niu and the engine experts from Han were sitting together for the test drive. Cheers to success.
In fact, even a 150-hour test run is only the first step in the long march. There are many tests behind, such as high-altitude simulation test run, start-up test run at minus 40 degrees Celsius, and cyclic fatigue strength test of the five major components. It needs to be expanded next.
However, this is a staged victory after all.
Wu Lao rested for a few hours, and now he is in good spirits. He is sitting on the rostrum with Niu people on one side and Han people on the other, while Qin Guan and Stanley are sitting on the left and right.
Stanley's eyes were still strange. Although the celebration had just finished, his eyes were constantly sweeping over everyone. Qin Guan knew that he was looking for someone.
Who are you looking for? Of course Professor Zhang!
"Mr. Stanley, please don't worry. Professor Zhang is still on the way and will probably be there in a while." Qin Guan said: "Now, let's talk about the development of Spey first. The next experimental project, we I want to continue doing it with us."
The development of engines in Han China is seriously lacking. Those test equipments were from the previous turbojet era. Now that Spey is engaged, it is necessary to start from scratch and introduce it again.
Manufacturing equipment is necessary to introduce, because to produce an engine, there must be equipment. However, this kind of testing equipment is often wasted and is only used in design, that is, there is only one opportunity to use it.
Therefore, after hearing Qin Guan's words, Stanley was suddenly surprised: "These are outside of our contract. If you want to do the next experiment here, then continue to buy our equipment and we need to continue to quote. "
This is not our wild asking price, this is your own swollen face to fill the fat.
"Yes, we can accept these additional costs." Qin Guan said: "This is the first thing, and the second thing is about our modification on the Spey. We want to further reduce the Spey engine. Quality, improve its thrust, thereby improving the performance of this engine."
Hearing Qin Guan’s words, Stanley pretended to be embarrassed:
I’m afraid it will be difficult? The improvement of Spey’s engine is not so easy. Moreover, the company has no plans to improve Spey. A lot of investment!"
What is the total amount of Han's foreign exchange reserves? Stanley didn't believe that the Chinese people could put all their foreign exchange into Spey's project. If there is too little, you can leave it alone.
"You have no plans?" Qin Guan said, "How do I think it is not? As far as I know, you are preparing to actively bid for the engine project of Eagle Country's Tomcat fighter?"
When Qin Guan said this, Stanley was stunned.
The Spey engine, which has good performance, was also produced by the Eagles with a patent license. The non-afterburner model was used in their attack aircraft.
At the same time, Allison, which purchased the patent, also aimed at a new gap.
Yingguo is very strong in engine research and development. It has produced the F100 series of third-generation engines, but now the reliability is greatly reduced. Most of the F-15s are lying down because of the engine.
As for their Tomcat fighters, they use TF30 engines. This kind of old-fashioned engine originally prepared for bombers is definitely not suitable for use in fighter jets, so it is also faulty.
The Eagle Nation’s navy wants to change its engine. Spey’s modification in Eagle Nation, the TF41, has great hope. However, if it is used for Tomcat, it has to be improved and its thrust must be further increased. According to them The plan is to increase the thrust to the order of 11.4 tons.
This is Spey’s big change. There is a market abroad. Although Allison is ambitious, it is not so easy for them to change themselves. They can only turn to Spey’s old boss, which is Rollo. The company is now, and everyone will research and develop together.
In this regard, Rolls-Royce is not particularly attentive, because they actually do not have much confidence in this improvement project. Even if it is improved, it is a temporary substitute.
But now, Han Guo actually has this idea. Before the imitation of the Spey engine has been completed, it wants to improve it?
To be honest, Stanley was tempted. If Han was to share R&D expenses, he could consider it.
At this moment, Qin Guan spoke again: "For this improvement plan, we require our technicians to participate in the whole process and go through the whole process. As for the cost of the project, we can afford it."
When Qin Guan finished speaking, Stanley knew what Qin Guan wanted to do.
Han people, the appetite is really big.
The party can transfer the production license and technical data of Spey, provide all assembly and parts drawings, process specifications, various technical specifications and manuals and tooling drawings, and send experts to provide technical assistance. But all this does not include our own design experience in the process of developing the engine!
The design of an engine is not accomplished overnight. It requires hard work and many failures. The same is true for Spey’s development. These failures are also useful for reference.
Now, even if the whole set of Spey technology is given to Han, for Han, they can only produce according to the technology, but they cannot make improvements.
If you don’t know the original design of the engine, or why this part is designed in this way, then you can’t make improvements. As long as you change a little, it will bring a terrible chain reaction.
Now, Qin Guan proposes to improve Spey and participate in the whole process. He wants to thoroughly understand the design principles so that they can improve again in the future and even cultivate their own R&D team.
How does that work!
"No, no, no, we can sell products, we can also sell technology, but we just don't sell brains." Stanley said.
Just as in Niu Country, Stanley called out loudly, what we sell is fruit, not fruit trees, it is actually the same reason
Through this imitation, they taught the Han people how to design aero engines and how to balance the contradictions of various data? When the people of Han people understand this engine, they can change it back and forth. Increase the bypass ratio and use it for passenger aircraft. Lower the turbine temperature and turn it into a gas turbine for use in warships. Finally, a large series will come out. .
They are not so stupid, and they are not the big brothers of Xiong Country back then.
"We can use the advanced single crystal turbine blade technology we have in exchange for it, and it can work stably at 1,700 Kelvin." Qin Guan said.
