While Tikran and Navalli were negotiating in the right and best interests of their side, Alison was persuading Ling Shizhe to give up working with those steel companies.

His reason is simple, since we got this technology by accident, why take it out and share it, wouldn't it be good for us to build a smelter ourselves? And with the continuous development of the Ambrera Group, the company has more and more types of various new materials, many of which are not available on the market, which requires us to develop our own, and these new materials are not limited to the field of steel. In this way, the coordination and matching between the various partner companies is a headache.

And if you cooperate like this, what should you do with the metallurgical laboratory and merge it into a cooperative factory? What is the appropriate proportion of R&D funds from both sides? Those steel companies are all their own R&D units, and they will never promise the emergence of another metallurgical research institute outside of their own R&D system, and they will definitely try their best to drag you back.

Ling Shizhe had a different opinion: "Alison, I admit that there is some truth in what I said, the reason why I took out the titanium alloy technology to cooperate with those steel mills is that it is impossible to produce everything by myself; Second, this titanium alloy technology looks very high-end, but it has one of the biggest problems, that is, the processing and welding of titanium alloy is too complicated, therefore, on the road to the localization of machine tools in East Germany, I do not plan to use titanium alloy chassis. ”

"You're not going to use a titanium chassis, so what material do you use instead?" Alison didn't expect to get such an answer after such a big effort.

"I'm going to use CRMOV alloy steel." Ling Shizhe gave the answer.

Since he knew that the titanium alloy steel used in the material of the train site could be used for military purposes, he went to ask the train experts in East Germany why titanium alloy was used to make the chassis of the train, didn't he know that titanium alloy was very difficult to process.

The answer of the East German experts made him laugh and cry, it turned out that they did not want to use titanium alloy as a train chassis, but their CRMOV series alloy steel production technology was not up to standard, so they had to do so. So Ling Shizhe had a plan to replace titanium alloy steel with CRMOV alloy, he carefully consulted the steel material catalog of Western countries, and found that CRMOV alloy steel technology is very mature in the United States and the United Kingdom, and has been developed for two generations, there is no problem with him to replace titanium alloy, and then Ling Shizhe told the metallurgical department that the train site was changed to CRMOV alloy steel.

And this titanium alloy steel he decided to continue to use, cooperate with the steel mill to sell it to the military, and earn back the cost of the initial investment. He didn't plan to merge the metallurgical labs, which, as Alison said, would be quite troublesome if they did.

Therefore, in metallurgy, his ultimate plan is to develop it himself, and then produce it himself or cooperate with others according to the actual situation.

After communicating his plans with Alison and reaching a consensus, Ling Shizhe took his private jet to Hong Kong.

The TN-30 turbofan engine has been copied, and it is about to be ignited for trial operation, and Ling Shizhe will definitely rush back for such a major matter.

The TN-30 engine was jointly developed by Pratt & Whitney, GE, and Honeywell to verify the modularization, serialization, and standardization of future aero engines, so this engine is only a test product and has no usability.

But Ling Shizhe introduced it, and the purpose of introducing the TN-30 was not to obtain the technology of American-made engines, but to obtain the design ideas of American aero engines.

Aero engine has three cores, design, materials and processing and manufacturing technology, he knows that the Americans will not transfer aero engine technology to the Chinese no matter what, so Ling Shizhe did not think about these two, he had the idea to hit the design early. Because compared with the latter two, the correct design idea is the most valuable.

TN-30 is such an engine, and the Americans will naturally unconsciously reflect their own design ideas in TN-30 after verifying whether the idea of modularization, serialization and standardization is correct or not. From the late 70s to the early 80s, the Republic introduced Spey turbofan engine technology to the UK, and the British gave the engine material technology and processing and manufacturing technology, but did not give the design ideas, so it can be seen that the design ideas of the turbofan engine are more important than the manufacturing technology itself.

After getting off the plane, he left the airport through a special passage, and drove back to Hong Kong without informing anyone, and drove to the newly built jet and propulsion laboratory in the New Territories, where he found that there were a surge of people, countless technicians in white coats, busy on various types of equipment installed outside the special ground test platform, and the snow-white spotlights on the roof of the workshop were all open. The whole workshop is fully revealed.

On the light yellow dust-proof floor of the workshop, one is more than four meters wide and eight meters long. A silver aluminum rectangular object more than five meters high is placed in the middle of the workshop, and many steel scaffolds are built horizontally and vertically around the rectangular box, and two square holes are opened at both ends of the upper part of the rectangular body, one is open, and the other is connected with a square pipe winding towards the outside of the workshop.

It is a special test platform, two square holes, one is the air inlet, the other is the exhaust port, the temperature of the exhaust port is very high, so it is necessary to use a pipe to connect it, and put the high-temperature gas outside the workshop.

Aero engines are a very sensitive technology, even with the authorization of the United States, and Hong Kong is too small, so Ling Shizhe divided the jet and propulsion laboratory into two, one in Hong Kong and the other in Raccoon Town. The laboratories in the two places have their own division of labor, and Hong Kong is the most important R&D centre.

This is a prototype produced in full accordance with American drawings, the TN-30 engine has a modular design, consisting of 10 units, and the overall weight of the engine is only 1364.7 kg. Each unit component is very easy to disassemble and install, and the general crane can easily transfer the whole component out, which is quite convenient for maintenance.

The exterior of the engine adopts the popular box package, and several thick cable sleeves load all the running and test wires together and penetrate deep into the box. The appearance of the whole unit is very clean and neat.

Ling Shizhe came over quietly, so everyone didn't notice him, Wang Yuanzhuo, the person in charge of the jet and propulsion laboratory, was wearing a white coat and holding a document board, and was talking to the staff around him, Mark and Zhou Yuanhang were also there, the two stood beside Wang Yuanzhuo, and they didn't say a few words, what surprised Ling Shizhe was that his father Ling Zhigao, father-in-law Li Chunlai and Wang Haihua, dean of the School of Computer Science, actually came over, pointing at the TN-30 engine placed on the test platform, with indescribable excitement.

Ling Shizhe walked over and shouted, "Father, old Taishan, what are you so happy about!" ”

With this shout, Ling Shizhe exposed himself, and everyone stepped forward to shake hands with him and say hello, Wang Yuanzhuo walked up to Ling Shizhe and said, "Boss, I thought you would come over tomorrow, but I didn't expect you to be so fast." ”

Ling Shizhe laughed and said: "Our Chinese's first turbofan aero engine is tested for the first time, of course I have to rush back at this historic moment, how can I be sure?" A sentence of the Chinese's own turbofan engine ignited everyone's emotions, at this time the vast majority of Chinese scientists still hold the dream of rejuvenating the country through science and technology, but unfortunately, the class struggle on the mainland is in full swing, looking at the fate of the predecessors, they know what awaits them when they go back, it can really be described as having no way to serve the country, so they accepted Ling Shizhe's recruitment, in Hong Kong, a small place, with that poor dream of rejuvenating the country.

"It's hard to say, this turbofan engine is just an American test product, there will definitely be many problems in it, I can only guarantee that I processed it in strict accordance with the requirements of the drawings, as for what defects the TN-30 engine has after the test, I think it will soon be exposed."

Ling Shizhe waved his hand and said: "What is the TN-30 engine, I know better than you, if you really follow the drawings, you can rest assured, there should be no problem in the test stage." ”

The TN-30 was first equipped on the F-14 fighter, but the TN-30 was originally a technical verification product, and the blades of the engine would break during the flight test, causing serious air flight accidents, so the early F-14A fighter was lying on his stomach all day long and did not dare to go to the sky, so he was called a hangar bully.

Blade breakage is only one of the many problems of the TN-30 engine, and spraying parts for no reason after going to the sky is also a very fatal problem, although the air performance is not good, but when doing ground tests, the TN-30 is still very safe.

After talking to Wang Yuanzhuo, Ling Shizhe came to Ling Zhigao and Li Chunlai's side, and watched the two old men looking at the TN-30 turbofan engine in front of them, with a complicated look in their eyes.

When everyone saw that the two fathers and sons were together, they knew that they had something to say, so they automatically gave up a space.

Ling Shizhe stayed by the two old men and didn't speak, the three of them just stood and looked at the TN-30 in front of them, and their hearts were mixed. After a long time, Li Chun said: "I can't see the day when it is equipping our army, but it is good to see it test today." ”

Ling Zhigao said: "Yes, Lao Tzu didn't eat the bombs dropped by the devil's plane back then, and now we finally have our own aircraft engine, I believe that it won't be long before we will see our own plane in the sky."

Ling Shizhe twitched his cheeks, and he didn't know how to tell the two old men, could he tell them that this engine is actually a rotten thing, and my son I introduced it just to find out the Yankees' aero engine design ideas, and it is impossible to equip our army. And the authorities are already engaged in IDF, they have to kneel and lick the Yankees, it is impossible to ask for an engine made by your son...... You two old men are blind men who light lamps in vain.

As long as Ling Shizhe said this, the two old men would be angry, so Ling Shizhe simply didn't say a word, just accompanied the two old men.

"Sir, it's almost time, they're going to test the car." Li Chunlai's adjutant Wang Xin saw that the time was almost up, so he walked over and reminded him in a low voice.

"Let's go outside and don't disturb the children's work."

The hour hand pointed to nine o'clock, Wang Yuanzhuo confirmed each link of the unit's ignition operation three times, cleared his throat and walked up to the half-high platform to observe the engine intake, the staff below watched Wang Yuanzhuo climb to a high place, the voice of the conversation suddenly became smaller, and the breathing of the entire test workshop was gradually silent.

Wang Yuanzhuo looked around the workshop and said: "After nearly two years of hard work, it is finally time to test. ”

Dizzy! When did they learn the set of Wenshan and Huihai, and still speak, when the time is up, just ignite the test and don't it be over, and speak.

The bursts of applause below made Ling Shizhe have to walk up to the half-high platform, looked at everyone and said: "I won't say more, the time for inspection has arrived, let's ignite and test the car!" ”

Wang Yuanzhuo came to the front of the helper's console, took out a key and inserted it into the keyhole, click! With a bang, a plexiglass box split to the sides, and a crimson button switch with a diameter of two inches leaked inside. Wang Yuanzhuo pointed to the button and said, "Chairman, please light the fire." ”

Ling Shizhe smiled and refused: "That's your achievement, or you should light the fire." ”

"You are the chairman of the company, and today is the first ignition test of our aero engine, and it should be up to you."

Seeing Wang Yuanzhuo say this, Ling Shizhe did not shirk, and walked to the operating table, after Wang Yuanzhuo explained the operation method to Ling Shizhe, he gave up the space and stood behind Ling Shizhe's side.

He took a deep breath and pressed the crimson button on the workbench heavily.

After a low humming sound of the motor, Ling Shizhe saw the scaffolding built near the unit tremble slightly, and a unique whistling sound when a high-power current passed through the wire came from the small and very large, and the turbofan engine started......
