"Mr. Clay, is there any problem?"

"Your chopper...... No, nothing, I still need a little more time to make sure the device is OK. ”

Klay Thompson touched his head, activated all his brain cells with all his might, and observed the real equipment on the table without letting go of any details.

The volume of choppers in this era is very large, and if you follow the number of test calibrations, it is obvious that the chopper will be a device that cannot be ignored.

However, Klay Thompson searched all over the real table, and none of the equipment on it resembled the size of the chopper he was familiar with. There was a device he didn't recognize, but looking at its palm-sized size, it didn't look like it could achieve a chopping function.

He searched up and down the table, and he picked up every piece of equipment and carefully observed it. However, there are no superfluous lines or special settings, whether it is variable silicon or GTO, they are not in sight.

In the end, Klay Thompson had no choice but to point to the box on the table that he didn't know what to do, and asked, "Excuse me, what is this device for?"

"Chopper. Fu Zhiheng glanced at Hu Wenhai and stood up and said.

"This is a chopper? I've never seen a chopper like this before, can I open it and take a look?"

Klay Thompson tapped on the chopper's casing, a tightly sealed composite box that left only the interface for the passage on the surface. As for any of the settings inside, they are not visible from the outside at all.

"That's not going to work. Hu Wenhai shook his head: "Trade secrets, can only provide testing, and the internal structure cannot be shown to you." ”

Klay Thompson shrugged and nodded helplessly.

Black box testing, this kind of testing method is not unfamiliar to him. But can such a small device really achieve the chopper function? Klay Thompson was quite curious.

Either the Chinese really invented a small inverter, or they played tricks with some tricks. From Klay Thompson's point of view, it's clear that the latter is more likely.

"So please get started, I can't wait. ”

Can't wait to debunk your tricks, what are you kidding, such a small device fulfills the function of a chopper?

Klay Thompson rubbed his hands together and glanced around the test bench, intending to conduct a thorough inspection after the start of the test, there must be something wrong here!

The inspection of the chopper is not difficult, since the Chinese say that the black box can achieve the chopper function, then the voltage, pulse width and frequency at both ends of its input and output terminals must be different. Unless there is a problem with the testing equipment, the test results must conform to scientific laws. Whether it works or not is actually very easy to see.

Strict reproducibility, which is the basis of science. In the 80s, many pseudo-scientists claimed to have invented such a great technology, but none of them dared to go through the process of scientific and technological identification, because these tricks had no possibility of being able to pass in the face of truly rigorous verification.

"Oh, that's right!" Klay Thompson stretched out his hand to block Hu Wenhai, who was about to start the real equipment, and smiled slyly: "I need to make some modifications to the real equipment, I brought my own testing equipment, don't you mind?"

Looking at Hu Wenhai, who was "forcibly calm", Klay Thompson raised his head proudly. He took a box from Stuart and opened it to reveal an oscilloscope.

An oscilloscope, as the name suggests, is a device capable of converting electrical signals into a visible image. As a versatile electronic measuring instrument, oscilloscopes made in Germany are the high-end products on the market.

On weekdays, Klay Thompson has this oscilloscope in his hand, and he will not let others use it. Whenever he operated this instrument, the eyes of the Chinese around him were full of envy.

Of course, the Chinese are not without oscilloscopes to use. However, compared with the bulky and crude Chinese oscilloscope, he is a few streets ahead of Chinese products in terms of function and design.

He looked into Hu Wenhai's eyes, wanting to see those familiar and amazed glances in his gaze.

Unfortunately, all he gained was peace.

"No problem, does Mr. Clay need my help?" asked Hu Wenhai with a nod.

Cut, the Chinese are doing really well on the surface, this is the so-called city government, right? Joy and anger are not visible or something? Klay Thompson felt slightly unhappy that he did not see the expected scenery.

"No, I'll do it myself. Klay Thompson refused Hu Wenhai's help and took matters into his own hands.

With a few clicks, he connected the oscilloscope to the line. I turned on the switch and adjusted it, confirmed that the device was in good shape, and then nodded.

"It's time to go. ”

Hu Wenhai closed the switch, and the silent current was connected in the circuit. On the oscilloscope, a wave-like curve popped up almost instantly.

"Oh, the output of the DC generator, the generator in China is not too stable......"

Klay Thompson glanced at Hu Wenhai, and a smile appeared on the corner of his mouth. The current output by the domestic diesel generator is not stable in the oscilloscope table, but has a certain fluctuation. This kind of fluctuation is obviously impossible to qualify if it is placed on the German generator. As a German power engineer, he certainly has a lot of pride.

How could China, which could not even build a generator, build the world's most advanced chopper? Even Germany, which is the most advanced in this regard, could not have made the latest GTO turn-off thyristor so small.

However, he still couldn't see any nervous expression on Hu Wenhai's face, or whether it was Hu Wenhai or Fu Zhiheng, there was almost no love on their faces.

Difficult Chinese.

Klay Thompson snorted in his heart, and he didn't believe that you would be able to keep this expression on his face in the future.

He switches the line to the other side of the chopper black box if this is a normal chopper......

The corners of Klay Thompson's smiling mouth suddenly stiffened, and then the upturned corners of his mouth turned into a downward pull, and the expression on his face was full of incredulity.

"Surely my scope is broken!"

He patted the oscilloscope that he usually regarded as a treasure, but unfortunately, the rectangular waveform on the monitor hardly changed.

Klay Thompson didn't give up switching the line back to the circuit before the chopping wave, and then switched back again, rubbing his eyes-

However, this does not change in any way, and the waveform on the chopper is still a straight rectangular waveform.

"Mr. Clay, efficiency, the efficiency of the chopping wave is the key. Stuart saw Klay Thompson's bewildered face and had to warn him.

"Oh, yes, efficiency!" Klay Thompson suddenly woke up, the chopping function is just the foundation, efficiency is the key! Electric transmission is not a new technology, but it has never been popularized and applied, and efficiency is the fatal wound!

Klay Thompson hurriedly compared the waveforms and numbers displayed twice, took out a pen and paper in his hand and calculated for a while.

"How's it going, Mr. Clay?"

Klay Thompson frowned, as if something terrible had been born out of his hands.

"The gate drive consumes only 50% of the power consumption of GTO technology, the switching frequency is 3000Hz, and the performance is at least six times that of the GTO chopper!"

Klay Thompson didn't seem to believe what he said, and quickly calculated twice in his hand, and after making sure that the calculation was correct, he had to stop.

"If the IGCT chopper is used in an electric drive, is the transfer efficiency higher or lower than that of a mechanical drive?" Stuart finally asks the crucial question.

Although Klay Thompson is an electrical engineer, he has worked for Volkswagen for many years and is no stranger to mechanical drivetrains. He was silent for a long time, and then he said unwillingly: "In some cases, the efficiency is higher than that of mechanical transmission, but for our German mechanical transmission, the efficiency of electric transmission is not enough to form an advantage......"

Klay Thompson is a dead duck with a hard mouth, as the three people present could tell.

Hu Wenhai and Fu Zhiheng glanced at each other at this time, and couldn't help but smile.

"Ahem, if Mr. Stuart thinks this test is not accurate, he can find another authority to conduct the test, and we welcome it at any time. ”

Stuart woke up like a dream, I just went abroad to sell a production line, how did things develop to the point where it was related to the life and death of MTU?

Yes, the efficiency of electric transmissions reaches the level of mechanical transmissions, and in some cases even exceeds the efficiency of mechanical transmissions. This is definitely a matter of life and death for MTU.

Of course, theoretically, the efficiency of mechanical transmission will still be higher than that of IGCT's electric transmission. But the problem is that mechanical transmission is difficult to achieve good efficiency most of the time, while electric transmission can achieve good efficiency most of the time. The efficiency of the electric drive system is much higher.

The characteristics of IGCT mean that it will be particularly suitable for power transmission of large vehicles and ships, and the economic advantages brought by all-electric will greatly exceed that of mechanical transmission.

As a result, MTU is bound to revise the technical route. Although MTU also has a considerable accumulation in diesel generators, in this new market, it has given other companies the opportunity to overtake in corners.

Stuart still has this sense of crisis. IGCT technology must be in the hands of MTU! Only by gaining more time than other companies can MTU continue to maintain its advantage in the diesel engine market.

Of course, MTU can also choose to suppress IGCT technology, setting off public opinion and biasing the market against it, describing IGCT as a technology with no future......

But the problem is that it is not a single company that stands behind IGCT technology, but the entire Chinese government. Looking at the fact that Fu Zhiheng dared to issue a letter of guarantee, we can see how determined China is to promote IGCT.

No matter how powerful the MTU is, can it be more powerful than one of the five major hooligans on the earth? Although China's strength and discourse power are not high, the market of more than one billion people wants to promote IGCT technology, which is enough to provide enough persuasiveness.

Any false propaganda is only useful when there are no facts. With a real application case, if MTU wants to splash dirty water, it will be a slap in the face.

"Of course, our CTO from MTU will arrive tomorrow, and we'll have to trouble two more by then. Stuart nodded with difficulty.

......

MTU's CTO didn't come alone, instead, he brought an entire power technology team with him.

In the following period, the CTO of MTU led the team to study the small box of IGCT for three full days. Except for the black box that carried the IGCT chopper, almost the entire equipment of the real yàn was replaced. The Germans even brought a magician with them to find out if Chinese had applied any magic tricks......

But three days later, although not reconciled, the team at MTU still determined that IGCT technology has a strong advantage over GTO technology in terms of chopping and rectification.

An exam question is placed in front of MTU, whether to resist IGCT technology, or to consider the new technical route of diesel generators under the framework of electric drive technology?

After a heated discussion at MTU's headquarters, we finally had to face reality. With the energy of a single company, it is impossible to confront the Chinese government.

"The technology of the 1163 engine production line, we can provide. However, MTU demanded that the Chinese side must transfer all of IGCT's technology and licenses. Stuart sat back down at the negotiating table, but his tone was completely devoid of what he had been.

He waited anxiously for the reaction of the other side, but unexpectedly a jiàn clip was thrown in front of him.

"Regarding the issue of the 1163 engine, I don't think we need to bother with the MTU company anymore. It was Fu Zhiheng who spoke, and he smiled proudly: "The Canadian Kerbal Engine Company has expressed its willingness to cooperate with us in the production of 1163 engines at any time. Mr. Stuart remembers the company of this 'friendly country', right?"

When Stuart heard this, he hurriedly grabbed the text folder, opened it and quickly browsed through the copy of the text inside.

Without waiting to finish reading, he threw the text on the table and shouted angrily: "This is unreasonable, our authorization of the Kerbal company is a one-time one! They can't re-authorize!"

"That's right, so we offered Kerbal a favorable condition by agreeing to build a cooperative production plant in China for the production of Type 1163 diesel engines, and then buy back the engines produced. Fu Zhiheng was there, leaning on the back of the chair and sitting down: "This is not a violation of the contract you signed with the Kerbal Company." ”

"It's—it's!" Stuart shook his fists in a clenched fist, but was speechless. From any point of view, there is nothing wrong with this approach of the Chinese.

It's just that Stuart couldn't figure it out at all, and he really came up with such tricky methods that had never been mixed with the international market Chinese Didn't he say that the Chinese were all kind, simple, and had no sense of business? Aren't the Chinese rumors in the rivers and lakes all stupid and fast enough to spend a lot of money to buy outdated equipment? Stuart really wanted to cry without tears, and he didn't believe these rumors if he knew it, and how can he get back now when he offered a sky-high price of 100 million US dollars......

It can only be said that the Chinese's means of OEM resale are really too cheap!

The MTU company has no way at all, and as long as the Chinese come up with a transfer fee of 10 or 20 million, the Kerbal company will definitely come up to engage in cooperative production. Stuart could even imagine the scene of the "hot" engines that had just been produced, with Chinese customs officers stationed in the factory, stamped with large bright red stamps, and nominally the engines were resold and then imported from Canada.

The Kerbal company has long earned enough money on the 1163 engine, and these transfer fees are completely taken for nothing, and you can earn 20 million dollars by moving your mouth and signing it, and it is impossible for MTU to persuade Kerbal to give up these benefits.

It is impossible to give up the money that was earned so easily! What's more, the 1163 engine was bought, not developed by themselves. Why not be generous to others?

Stuart let out a sigh of relief, forced himself to calm down, thought for a while and said: "Chief Engineer Fu, our MTU is a research and development enterprise of the 1163 engine, and it has a higher technical level than the Kerbal company. If the Chinese side imports the production technology of the 1163 engine from our company, it only needs 20 million US dollars, and we can help China establish a more complete and advanced production system, and even the transfer of follow-up products is not impossible for us to discuss. ”

Stuart's key point is very accurate, and the biggest cost of MTU is the technical advantages of the system and the continuous introduction of follow-up products.

Hearing his words, Fu Zhiheng's eyes immediately lit up: "What does Mr. Stuart mean is that other engine technologies can be transferred in the future, such as the 1163-3 type with more than 10,000 horsepower, or the MB873KA-501 engine?"

Stuart was drenched in cold sweat when he heard this, and hurriedly shouted and shook his head: "This is impossible, the MB873KA-501 engine is the engine of the Leopard 2A4 tank, and it is impossible to transfer it to the Chinese side!"

"Oh, what about the 1163-3 engine?" Fu Zhiheng smiled at the corner of his mouth.

The Chinese are really a bunch of devils!

Stuart sat back in his seat and nodded: "We can write the transfer of the 1163-3 engine in two years into the agreement, before that, you must first absorb the technology of the 1163 engine, and then you can upgrade to the technology of the 1163-3 engine." ”

Fu Zhiheng glanced at Hu Wenhai, both of them had a smile in the corner of their eyes, their faces were satisfied, but their voices seemed to have been wronged: "Okay, we can consider postponing the technology of the Type 1163-3 engine for a few years." However, in order to prevent MTU from defaulting, we will ask for a relatively high default amount. ”

Stuart nodded: "Of course, we will honor the agreement." ”

"So, let's talk about IGCT technology. Stuart regrouped and straightened his waist, but involuntarily slumped his back: "MTU hopes to get IGCT technology, please ask Mr. Hu to make a price." ”

Stuart touched his head and looked at Hu Wenhai with some apprehension. If he were a black man like Klay Thompson, with a bald head, it would be like touching a glittering tea egg.

It looked like asking someone to kill a customer.

Hu Wenhai rubbed his hands and raised the "butcher knife" that had been prepared long ago. It is rare to meet such a "stupid and fast" customer, and you always have to quote a price that meets the grade of tea eggs!

He knocked on the table, pondered for a moment, and then said, "I have three options for MTU to choose from, and Mr. Stuart can fully consider it before giving me an answer." ”

"The first plan is to buy out the global patents of IGCT technology, with an offer of 10 billion US dollars. ”

"The second option is to buy out the patent licenses in European countries and offer five billion dollars. ”

"The third option, technology licensing in Europe, offers a billion dollars. ”

Hu Wenhai's three fingers fell, and Stuart seemed to have just been fished out of the sea, and he was sweating all over, wetting his shirt in many places.

"This price is too high, $20 billion, and it is impossible for MTU to accept it. Stuart said in a hoarse voice.

"But it's worth the price!" Hu Wenhai waved his hand domineeringly, and said categorically: "IGCT technology is 10 billion US dollars in the world, and it will not take ten years to earn it back." Not to mention the resulting market dominance, how much benefit will this bring to MTU?"

"Even if you don't choose 10 billion global patents, you don't have 5 billion dollars of European patents, or 1 billion dollars of European technology licensing. Hu Wenhai was kind and persuasive: "It's not like MTU can't even get a billion yuan, right? Your shares in the International Aero Engine Company are more than that." No, we accept a variety of payment methods. For example, production equipment, technology and, of course, shares. ”

Fu Zhiheng interjected appropriately: "For example, the MB873KA-501 engine technology, we in China are definitely willing to come up with a figure that is very satisfactory to MTU." ”

"No, no, we will not give away the MB873Ka-501 engine technology!"

Contrary to what he said, the wavering meaning in Stuart's words was palpable.

Fu Zhiheng is simply a demon who wants to lure MTU to fall!

Stuart felt like he couldn't hold on much longer, this ******** was terrible!

"Then take the bearing technology of the aero engine in exchange? I think the bearing technology in Germany is still good, oh, by the way, MTU provides a lot of technology to the international aero engine company, and we are also very interested. ”

Stuart's eyes lit up when he heard this, as if a drowning man had grasped a life-saving straw.

Aero engines are not the core business of MTU, but in the development of the V2500 engine, MTU has undertaken a considerable part of the important technology.

The V2500 aero engine's 5-stage axial low-pressure turbine, as well as the turbine's three-dimensional design blade shape and blade tip active clearance control technology, were developed by MTU. In addition, the German bearing technology is well-known in the world, and the service life of aero engines in Western countries is much higher than that of the Soviet Union, but there are most of the reasons that come down to bearing technology.

MTU's high-speed diesel engines also use bearing technology, although there is still a gap between the highest level of craftsmanship in Germany, but it can also be regarded as a leading role in the second echelon.

Dead friends don't die poor, it seems that they can only ask the International Aero Engine Company to "die".

Stuart slapped his big hand, and his momentum was like a rainbow: "Okay, buy out the European patent, we want to buy out the patent of IGCT technology in Europe! Technology, equipment, patents, plus a part of cash, five billion is no problem!"
