hung up the phone, Lin Hongfei was in a good mood.

The aviation system has finally taken its first step cautiously.

Although Ma Lao and they have only come up with a plan now, and even in the actual hands-on process, this plan still needs to be modified according to the actual situation, and there is still a long time before it can finally be finalized and produced, but this has made Lin Hongfei very satisfied, through this, Lin Hongfei clearly sees one point: they are on the right path.

That's enough.

Although the road is still very long, and like all aviation manufacturing companies, it is very likely that he will face losses for up to 10 years or even 20 years, but Boss Lin believes that he can afford to lose this money.

Boss Lin, who was in a good mood, couldn't calm down after a few laps in the laboratory, and he was not in the mood to continue to do experiments and designs.

Wu Rongze, the chief designer and chief engineer of Wanshan Special Vehicle, has come, as the first person of the Republic of China's integral heavy military wheeled off-road transport platform, the imitation and progress of DT-10/30 are inseparable from him, Lin Hongfei is very curious to know whether Wu Rongze can afford this heavy burden.

…………………………………………

When Lin Hongfei arrived at the test site dedicated to off-road models, a large group of people were standing there pointing at the two test vehicles that had set off a burst of wolf smoke, looking excited.

Seeing Lin Hongfei coming, everyone quickly gathered around, chattering and gossiping about their various opinions on these two cars.

There were many people, so many people were talking at the same time, Lin Hongfei couldn't hear a word clearly, and couldn't help but press down with his hands. It turns out. Lin Hongfei's prestige is good, seeing Lin Hongfei's action, everyone's reaction was very fast, and they immediately realized that their actions just now were a bit excessive, and they stopped one after another...... Everyone already knows that Mr. Lin himself is the top internal combustion engine and passenger car designer in China, and he is a technical technician, and he has a common topic with these people, and no one is angry and dissatisfied with Mr. Lin's action, but they are all waiting for Lin Hongfei to speak.

"You have also learned a little about this car in the past two days, right? What do you think? ”

"Incredible!"

"Whimsy!"

"It inspired me a lot......"

Everyone is gossiping. But the meaning is the same, no one thought that the original off-road transport vehicle can be designed like this, especially the unique hydraulic articulated structure, which is the core of this technique: the active torsion pitch of the articulated body. Combined with the 16-meter-long body, it can help the whole car achieve more powerful off-road performance than a tank. Before, everyone was worried about how to improve the off-road performance of the car. But I didn't expect it. There is such a simple way.

"Boss, since there are DT-10 and DT-30, is there another DT-20 in the middle?" Wu Rongze, the chief designer and chief engineer of Wanshan Special Car, squeezed hard to Lin Hongfei, and Wu Rongze, who rushed over from Wanshan Special Car, looked at the two DT-10PM and DT-30PM running at the test site with bright eyes, and asked Lin Hongfei with thirst for knowledge: He never thought of it. The cargo truck can also be designed in this way, even with rubber tracks! The load-bearing wheel is not the steel or alloy load-bearing wheel that everyone takes for granted, but a rubber tire!

Surprising, but the effect is also surprisingly good. He couldn't help but be overwhelmed by the whimsy of Vitesz's peers: there was nothing that could not be done, only unthinkable...... Some of the special vehicles of Wanshan Special Car can also learn from this design concept, right?

There is also a DT-30PM, which was naturally put aside, but it was not started, there were not many things, and when it was a "specimen", it naturally could not be wasted.

"That's right, but there is also a DT-20," Lin Hongfei nodded, "The 20-ton load also has all-terrain passing capabilities and amphibious operation capabilities......"

"Then why don't you get it back together?" Without waiting for Lin Hongfei to finish speaking, Liu Zhidong and Wu Rongze opened their mouths in unison to reproach.

Those who engage in technical skills are still a bit "bookish", which is still very different from those who do administration.

Lin Hongfei himself is also engaged in technical skills, so naturally he will not be angry because of this, and he doesn't care, he spread his hands and said, "I want to too, but our friends in Russia can't get it, what should I do?" You don't think this thing is like cabbage in the vegetable patch, a whole bunch of them waiting for us to pick and choose, right? ”

Liu Zhidong and Wu Rongze shook their heads embarrassedly: I ignored this problem, I heard Mr. Lin say that the DT-10 and DT-30 series tracked all-terrain amphibious transport vehicles are highly controlled all-terrain vehicles by the former Soviet government.

"Although I can't get my hands on it, I can tell you about the basic structure," Lin Hongfei raised his finger and pointed at the DT-10PM and DT-30PM that had gone away, and said, "The basic structure of DT-20 is basically the same as DT-10 and DT-30, which are two transport units in front of and one behind, and the two transport units adopt a modular design, which can be replaced at any time according to different needs into task modules for various purposes such as personnel riding warehouses and waterproof material transportation warehouses, and also use articulated structures. The difference is that the power system is different and the body size is slightly different, you see, the front car of DT-10 is 3 pairs of load-bearing wheels, the front car of DT-30 is 6 pairs of load-bearing wheels, the front car of DT-20 is 4 pairs of load-bearing wheels, the body is slightly narrower, I believe that with Wu Gong's attainments in heavy vehicles, according to DT-10 and DT-30 to find out DT-20 should not be difficult......"

Speaking of this, Lin Hongfei paused slightly, "Wu Gong, the reason why you came here is also because of this, I hope you can complete this product series and form a complete model sequence from 10 tons to 30 tons, how about it, are you sure?" ”

"Mr. Lin, how long can you give us?" Wu Rongze didn't answer immediately, but pondered for a while before asking Lin Hongfei, "In addition, can the research funding be guaranteed?" ”

Although the reorganization has not been completed since the merger of Wanshan Special Car into Guqi Provincial Industrial Manufacturing Co., Ltd., the cadres and workers of Wanshan Special Vehicle can not help but dare to smack their tongues for the wealth of Guqi Provincial Industrial Manufacturing Co., Ltd., which is more and more clear to the technical personnel of Wanshan Special Car.

"I don't set a time for you, Wu Gong, you should have a basic understanding of this tracked all-terrain amphibious transport vehicle in the past two days, right? In your experience, how long do you think it will take to get a prototype out of the equation with guaranteed R&D funding? Lin Hongfei asked.

"If we can ensure R&D funding and ensure that the power system does not lag behind, I promise that at most two years, we will be able to come up with a prototype!" Wu Rongze said with confidence, after studying the 543 integral heavy military wheeled off-road transport platform of the Minsk Automobile Heavy Industry Complex for so many years, this confidence, engineer Wu Rongze still has this confidence.

Lin Hongfei turned his head to look at Liu Zhidong, high-power heavy-duty diesel engines have always been Liu Zhidong and Sigmund. Mia's research direction, since the merger of the two high-power and heavy-duty diesel engine R&D departments, the design concepts of the East and the West have strengthened each other, and there is no shortage of R&D funds, so the progress is naturally fast.

"We guarantee that there is no problem with the power system," Liu Zhidong said with confidence, "Our department is now engaged in a compact high-power heavy-duty engine, which is the same as our 12V190 series, it is also a V-type 12-cylinder structure, but the overall structure is much more compact than the 12V190 series, I have seen it, the volume is similar to the V-46-5 multi-fuel diesel engine used on the DT-30, the maximum burst power of 750 horsepower in 5 minutes, and the maximum continuous continuous power can reach 650 horsepower, It can fully meet our requirements for copying this tracked all-terrain amphibious transport vehicle. ”

Wu Rongze and Liu Zhidong have also known each other for many years, the car and the engine are originally two inseparable wholes, with Liu Zhidong's words, Liu Zhidong immediately put his mind at ease, turned around and said to Lin Hongfei, "Two years, Mr. Lin!" In two years at most, I'll get you a prototype! ”

"Then it's hard for the two of you," Lin Hongfei was also happy with such a result, he thought about it and said, "The load-bearing wheels and tracks of this car are rubber products, in this way, you go to Ding Baoguo Ding of the four-corner tires, we are the biggest customers of their four-corner tires, since we have spoken, they will always give this face." ”

"Okay, good ......" Wu Rongze nodded happily, "As long as the problem of low-temperature lubrication is solved, then there is no big problem." ”

With the eyes of a technical technician, he naturally saw at a glance that on these two tracked all-terrain amphibious transport vehicles, the engine, hydraulic articulation structure, low-temperature resistant lubricating oil and rubber materials constitute the technical core of this tracked all-terrain amphibious transport vehicle.

When he said this, Lin Hongfei sighed silently in his heart: there is a way to solve the rubber products that can withstand low temperatures, but the problem of lubricating oil can only be found to buy a batch from Russia...... There are really no lubricating oil products in China that can withstand low temperatures of more than minus 50 degrees. (To be continued......)
