This time, he came to the Federal Republic of Germany to process parts, and Yang Weiping certainly had another purpose. He was almost certain that the top brass of the Mercedes company knew that he had come to Stuttgart and would definitely come to him.

The Germans have always been the world's leading in tank design and manufacturing, and their technical strength and heritage are no worse than those of the Americans.

In particular, Mercedes has a number of patented technologies in the field of diesel-powered heavy-duty trucks, which are unique in the world.

Moreover, Yang Weiping also knew that in 1963, the United States and the Federal Republic of Germany were ready to cooperate in the development of the main battle tank MBT-70. The agreement identified the U.S. company Taylordyne and the Federal German company Mercedes to develop candidate engines.

The MB873KA-500 engine developed by Mercedes passed the NATO 400H endurance test in 1967 and was selected as the MBT-70 tank power. However, in 1970, due to the termination of the cooperation and development agreement on the MBT-70 tank, the two countries parted ways, each developing its own main battle tank and tank engine.

Now, Mercedes has successfully developed the MB873KA-501 engine. This is a 4-stroke 12-cylinder V-type 90° angle water-cooled pre-chamber supercharged intercooled diesel engine with a power of 1103 kW at 2600r/min.

Compared with the new engine with a maximum output of 882 kilowatts designed by Yang Weiping, the power is even stronger!

However, the MB873KA-501 is a water-cooled engine, while the AVCR-1790-1A that Yang Weiping is now engaged in is an air-cooled engine, and the two are different in terms of use. The MB873KA-501 is larger and naturally heavier than the AVCR-1790-1A.

Yang Weiping made it clear that he wanted to use the AVCR-1790-1A turbocharged air-cooled diesel engine as a bait to fish out Mercedes' MB873KA-501 water-cooled pre-combustion chamber supercharged intercooled diesel engine.

Yang Weiping can conclude that an air-cooled diesel engine with a total weight of less than two tons but a maximum output of 882 kilowatts is full of temptation for both the American company Taylordyne and the German company Mercedes.

Now see Frederick come forward. Of course, Yang Weiping was overjoyed in his heart.

"Mr. Frederick, your eyes are as sharp as ever. Yang Weiping nodded and smiled: "I am making some technical improvements to the AVDS-1790 series of tank engines produced by the American Taylordyne Company. By my design standards, the new turbocharged air-cooled diesel engine can deliver a maximum output of 882 kilowatts. ”

"How many kilowatts are you talking about? An air-cooled engine can reach 882 kilowatts?" asked Frederick, his eyes widened in apparent disbelief.

"Well, 882 kilowatts is just my conservative estimate. Yang Weiping nodded indifferently and smiled: "My expectation is to reach 920 kilowatts." Because my cylinders and pistons are made of the kind of high-strength aluminum alloy I developed, the kind I sold to the British. In addition, high pressurization and variable compression ratio piston technology are also used. ”

"Yang. If I'm not mistaken, your new high-power, air-cooled engine is supposed to power some advanced medium tank. Frederick looked at Yang Weiping with deep meaning in his eyes and said:

"We at Mercedes are currently producing MB2KA-873 engines for the Leopard 501 heavy main battle tank in Germany. If you're interested, I think, the cooperation between the two of us. It can be expanded and deepened. ”

Hehe, the fish really took the bait. Yang Weiping forcibly suppressed the pride in his heart, but his face smiled quietly and said: "I have heard of the German Leopard 2. This is a combat behemoth with a full combat weight and a maximum speed of 72 km/h. My American Tiger has less than forty tons of combat full weight. ”

The total combat weight is less than 40 tons, but an air-cooled engine with a maximum output of nearly 900 kilowatts is installed, there is no doubt that the new American Tiger tank in John Young's mouth, its off-road speed and climbing ability, must be very terrifying!

Frederick's mind spun rapidly, calculating.

As everyone knows. The talent and ability of Yang University scientists in the field of materials research are unparalleled in the world. Moreover, the Federal Republic of Germany has reached an agreement with Tiangong Laboratory on the transfer of technology and patents for Y2013 alloy, and is planning to use Y2013 alloy for the internal structure of the Leopard 2 main battle tank to reduce weight. This further improves the performance of the Leopard 2 main battle tank.

Frederick also heard that the board of directors of Rheinmetall had decided to cooperate with Tiangong Laboratories in materials research.

Mercedes must strengthen its cooperation with Tiangong Laboratory!

Frederick made up his mind. Looking at Yang Weiping like an old fox, he said with a smile: "Yang, we have established a joint venture motorcycle engine manufacturing joint stock company, and I think we can cooperate again to establish a new diesel engine manufacturing joint stock company." ”

Hehe, that's what I'm waiting for is your sentence.

Yang Weiping's heart was secretly refreshed, but on the surface, he pretended to be contemplative.

After about a minute, Yang Weiping smiled and said: "Mr. Frederick, I originally planned to cooperate with the American company Taylordyne, because I am completely sure that with this air-cooled engine I designed, I can get the patent right used by Taylordyne in the ASVD-1790 series engine without spending a penny.

We are now very happy to work together on Mercedes-Benz motorcycle engine and vehicle manufacturing projects. In the words of our Chinese, it is better to find familiarity than to find life, and of course good things should be shared with friends. I think that's a good suggestion.

I can predict that our new company will not only be able to occupy a place in the global tank engine market, but will also be able to obtain a part of the military budget of developing countries. This is because the medium tank I designed is very much in line with the needs of developing countries.

Its cost performance far exceeds the Huaxia Type 59, the Soviet Union's T54 and T55, and France's AMX-30 tanks. In the Far East, the Middle East, Africa and Central and South America, there is a huge market demand. ”

……

Yang Da scientist cooperated with the Federal German Mercedes Company to develop the American Tiger tank, and its technical strength is definitely stronger than that of the later Huaxia Machinery and Equipment Import and Export Company and the American Cadillac Gage Marsh Company.

The fire control system of the Leopard 2 includes two-way stabilization of the cannon, digital computer, laser ranging, thermal imaging night sighting device, etc., which are all good treasures that make Yang Weiping greedy.

The 105mm/L7 tank gun produced by Rheinmetall is more accurate than the 105mm/L7 tank gun researched by Huaxia itself!

Can the American Tiger that has been modified in this way still be the American State Tiger? Yang Weiping is full of expectations for this.

Mercedes' diesel engine manufacturing plant can produce the MB873KA-501, and it is certainly easy to improve a production line to produce the AVCR-1790-1A.

Husfeld's sense of smell was more sensitive than that of a dog, and Yang Weiping didn't intend to hide it from him. The newly established Mercedes-Tiangong Diesel Heavy Industry Group. Mercedes invested in MB873KA-501 technology and two production lines, Yang Weiping invested in AVCR-1790-1A technology and $30 million, and the Field family invested $240 million in shares, and the three parties shared all shares in a ratio of 433. Mercedes remains the apparent majority shareholder.

As for the negotiation with the American Taylordyne Company with the AVCR-1790-1A new technique, Yang Weiping didn't want to throw it to Hughsfeld to deal with.

For Mercedes-Tiangong Diesel Engine Heavy Industry Group, Yang Weiping values Mercedes' MB873KA-501 engine technology the most. Otherwise. He would never have given the Germans a forty percent stake. This is the indispensable engine technology of the main battle tank in the real sense of the Chinese Army in the future!

Although the American Tiger can also be called a main battle tank, it is much inferior to the German Leopard 2.

Mercedes-Tiangong Diesel Heavy Industry Group did not integrate all the diesel engine manufacturing plants under Mercedes.

However, Yang Weiping believes. With the deepening of the cooperation between the three parties, Mercedes Heavy Truck Engine Manufacturing Company will have to join in sooner or later.

to the newly established Mercedes-Tiangong Diesel Heavy Industry Group. Yang Weiping is more important than the production of motorcycles and weapons.

He spent three months in Stuttgart, which pushed back his scheduled return to China.

Tang Weimin and Qian Lao did not urge him after they learned that Yang Weiping was cooperating with Germany to establish a tank engine manufacturing company, and they returned to China ahead of schedule with a copy of the Type 59 tank improvement plan written by Yang Weiping himself.

The leaders of the Huaxia Military Commission saw the improvement plan for the Type 59 tank designed by Yang Da Scientist, and knew that Yang Da Scientist would provide a super air-cooled engine with a maximum output of 920 kilowatts for the new tank, which was tentatively named "Siberian Tiger", and also included the most advanced fire control system in Germany, and immediately stopped the research on the T62 tank.

Because of the Siberian Tiger main battle tank. Compared with the T62 tank under development in Huaxia, it is too powerful.

If it weren't for Scientist Yang Da's personal commitment, it would have been difficult for the leaders of the Huaxia Military Commission to believe that the "Siberian Tiger" main battle tank could really be built.

Big guy weighing up to 40 tons. It can run faster than a car, with a maximum speed of 90 km / h, which can not be called a tank. It's a fucking steel monster!
