Chapter 352 Nanshan Transmission
There is no airtight wall in the world.

Naturally, America also heard about China's actions with the polar bears.

Whether it was the intelligence that America had obtained from within the Polar Bear or the information obtained from China, all of it was gathered at Woodcock's side.

"Smith, find out whether China is sure to use the intercontinental ballistic missile launcher to exchange for the Polar Bear fighter jets."

"Then see if we can find out how many fighter jets China has received in return, and whether they are the export versions of the Polar Bears or the same versions they use themselves."

Any trade in advanced weapons is not a simple commodity trade, and there must be complex things involved.

Woodcock knew this all too well.

It is like the United States purchasing various military and civilian products from China, and then providing aid to the opposition in Afghanistan. This is a typical example.

America's willingness to sell its advanced helicopters, which it had only equipped for a few years, to China also has a complicated background.

Otherwise, China would not be able to buy even the civilian version of the Black Hawk helicopter.

"From all aspects, this news should be relatively accurate, but the specific details of the transaction are unclear."

"If the country wants to block this deal, I think the best thing to do is to contact China and express our willingness to sell F-15 or F-16."

"Otherwise, there will be no way to meet the needs of relevant Chinese departments for advanced fighter jets, and it will be difficult to achieve our goal."

Smith has a more thorough understanding of the problem.

He is also very clear about the current level of China's fighter jets.

Objectively speaking, there is still a huge gap between us and the polar bears and the United States.

In this situation, Smith can fully understand China's desire to obtain advanced fighter jets and its urgent practical needs.

"It's not that we are unwilling to sell advanced fighter jets to China. The key is that the prices of fighter jets purchased from several military giants in China are not cheap."

"With China's current foreign exchange reserves, they would be reluctant to purchase fighter jets worth about $1 million each."

"After all, the formation of combat effectiveness cannot be achieved by simply purchasing a few advanced fighter jets."

"Considering that China's existing fighter jets are all products of the Polar Bear style, if they purchase our fighter jets, they will not match their entire system."

"So we had a brief contact before, but the other party was not very enthusiastic."

Woodcock obviously did not look favorably upon China's decision to purchase advanced products from America.

This is not a simple matter of buying a few products and then leaving.

The use of fighter jets involves communication issues of various maintenance and communication systems. Unless China intends to fully switch to American military industrial system products in the future, it will not easily consider spending huge prices to purchase them.

The most important thing is that if they are introduced from the polar bears, they can also be exchanged for missile launchers, thus saving relevant foreign exchange to the greatest extent.

In addition, Polar Bear's products will be easier to integrate into China's own system in the future, which is also very important.

"This is indeed a problem, but if we allow China and the polar bears to continue trading, it will be very disadvantageous to us."

"The fact that advanced fighter jets can be traded shows that the relationship between China and the polar bear has eased significantly, which is not conducive to us winning over China to deal with the polar bear."

Smith is well aware of how China is positioned in America today.

In recent years, why China's international environment has undergone tremendous changes.

Not only the United States, but also their friends have had tremendous changes in their attitudes towards China. This is because the United States needs to pull China together to resist the pressure brought by the polar bear.

Before 1985, the pressure posed by polar bears to the United States was enormous.

It was not until a few more years, when various problems within the polar bears began to become serious, that America's attitude began to change.

"China is a big country, and they have their own ideas about what they do."

"The reason their relationship with polar bears became strained was because they were unwilling to completely listen to polar bears."

"It is obviously unrealistic to expect them to completely obey us now."

"We have to find a way to make those people in the country understand this."

Woodcock felt that he had no confidence in hindering the deal between Polar Bear and China.

In order to minimize the impact of this incident on oneself, the best way is to convince people in the country to accept this matter, let people in the country realize the inevitability of such a thing happening, and then not care too much about the impact of this incident.

"I will sort out the relevant information and see how to make people in China understand this matter better."

Smith could naturally understand what Woodcock meant.

On this point, his interests were completely consistent with Woodcock's.

……

"Xiao Jiang, we estimate that the number of our launch vehicles exported and used domestically can reach about 100."

"After delivery, we basically need to consider upgrading some of the problems found in the past to meet the needs of the relevant departments in the next stage."

"The operation of the current missile launcher is still too complicated. In places with relatively good road conditions, the driver can handle it relatively easily, but in places with very complex road conditions, it will test the driver's level."

"We are going to simplify the operation of the upgraded launch vehicle for the driver, and one of the key projects is to use an automatic transmission instead of the current manual transmission."

The development of the Polytechnic Special Vehicle Factory this year has been very smooth. Seeing that the cooperation with Polar Bear will soon produce results, Zhu Jiansheng immediately started to work on the next step of technological upgrades.

Both the United States and the Polar Bear have mastered the technology of this launch vehicle. They have upgraded it on this basis and eventually became more advanced than China.

That would be a bit embarrassing.

There are some manufacturers in China that can produce gearboxes.

But the overall technical level is not advanced.

Especially when it comes to the design of automatic transmissions, Zhu Jiansheng has no confidence in other manufacturers.

"Nanshan Technology is indeed developing automatic transmissions and has made some progress."

"But the design of automatic transmissions for this type of large vehicle is very different from that for cars."

"It would be quite difficult to start research from scratch."

Although he is his father-in-law, Jiang Hui will naturally not be polite when it comes to dealing with each other as a family.

The Polytechnic Special Vehicle Factory has now passed the most difficult period and started to live a good life.

Then all related cooperation should naturally develop in the normal direction.

The large commercial vehicle gearbox market is a relatively closed market. Its potential cannot be compared with that of passenger cars, but it is not small either.

Jiang Hui doesn't mind if Nanshan Technology expands its technology in this area in the future. "I understand that it's difficult."

"After all, the gearbox on a commercial vehicle needs to withstand a lot of torque. The gearbox used on our launch vehicle, which weighs dozens of tons and reaches hundreds of tons when fully loaded, has even higher requirements in this regard."

"There are not many AMT gearboxes in use now, so there is no way to fully utilize the engine's performance, and it may even stall in special circumstances."

"The subsequent user department will definitely have great opinions on this situation, and we need to find a way to solve it."

Zhu Jiansheng is an expert in the automotive industry. Although his research achievements in the field of gearboxes are not as in-depth as Jiang Hui, he is also one of the best in the country.

Otherwise, I would not have been able to guide Jiang Hui to do his graduation project on the 4MT manual transmission.

"Generally, most heavy trucks are diesel vehicles, and the operating speed range of diesel engines is much smaller than that of gasoline engines, about 1000 to 2500 rpm."

"In order to achieve maximum torque and efficiency within the speed range of 0 to 120 km/h, more gears are required than for gasoline engines."

“Usually heavy trucks carry more cargo, so the more gears you have, the more efficient the engine power application will be!”

"In addition, when encountering different road conditions, more gears can be used to adapt, so as to achieve the best match between driving speed and output power."

"Another feature of having multiple gears is to improve fuel economy, so that the vehicle can be in the economical engine speed range at different speeds."

"When starting/accelerating a heavy truck, the torque is high. Setting more low gears can accelerate more economically and reduce the engine speed fluctuation caused by gear shifting."

"For example, when the 2nd gear reaches 2000 rpm and the 1000rd gear is engaged, the rpm drops to below rpm, which will naturally cause the car to accelerate poorly. Moreover, the fuel consumption will naturally be high if the car is kept working in this way."

"And if a heavy truck like an intercontinental ballistic missile launcher is driving on a mountain road, having more gears will save more fuel."

"For example, on a long hill, the third gear wastes a lot of engine power, and the engine power is not enough when it is switched to fourth gear."

"Many five-speed gearboxes have this problem. If you accelerate too fast, it will waste fuel and the car will feel uneven, so you need to add more gears to correct the defect."

"According to my calculations, in order to maximize the performance of the launch vehicle, the gearbox needs to have more than 20 gears, or even 30."

“This is a huge challenge for the gear transmission structure design inside the gearbox.”

When it comes to expressing difficult things, you naturally can’t let the leader rush forward all the time.

At this time, Hou Guoming, the technical director, has to stand up and speak.

As the head of BMW's automotive R&D center, he now also serves as the chief engineer of Nanshan Technology.

The position will only be given up when more suitable talents come in the future.

"Director Hou, you are right. In fact, the automatic transmission technology we need for our launch vehicles is very similar to that of heavy trucks."

"As long as you master this technology, the gearboxes in the domestic heavy-duty truck market will basically be yours in the future."

"Now, whether it is FAW or Second Automobile, the trucks they produce are basically light trucks. Only a few manufacturers such as our Polytechnic Special Vehicle Factory are developing heavy trucks."

"If you can develop a suitable gearbox for our missile launcher, we will also use it on our heavy trucks."

Zhu Jiansheng has tied the heavy-duty truck gearbox project to the gearbox of the intercontinental ballistic missile launcher.

Otherwise, the sales volume of the missile launcher's gearbox would definitely not be very high, which would be an unprofitable thing for Nanshan Technology.

Even if the sales price is very high at that time, selling for hundreds of thousands of yuan per unit, it may not be able to recover the R&D expenses and costs.

But if it is tied to the heavy truck project, the situation will be different.

Amortize part of the joint development costs to heavy-duty truck gearboxes, and at the same time everyone shares most of the production lines, and the situation will suddenly be different.

The demand for heavy trucks in China is actually still very large.

Not to mention a lot, we can definitely sell tens of thousands of vehicles a year.

Even as long as the Polytechnic Special Vehicle Factory can develop heavy-duty trucks, there will definitely be a shortage of supply.

"Hasn't the Polytechnic Special Vehicle Factory already contacted the Shaanxi Gear Factory and the Capital Gear Factory to discuss the development of the gearbox?"

"I heard that Shaanxi Gear Factory has also imported commercial vehicle gearboxes from the United States to provide supporting equipment for domestic truck customers."

Jiang Hui was very clear about the situation of the Polytechnic Special Vehicle Factory.

Before Nanshan Technology was established, various domestic vehicles also needed to use gearboxes.

The Hummer military vehicles and intercontinental ballistic missile launchers produced by the Polytechnic Special Vehicle Factory are naturally no exception.

The gearbox of the Hummer military vehicle is purchased from the Capital Gear Factory. The technical level is not satisfactory and can barely meet the requirements of use.

Not to mention the missile launcher. If its performance was very good, Zhu Jiansheng would not have brought his team to Nanshan Technology for exchanges.

"Their technologies are considered relatively advanced in China, but there is still a big gap between them and the level we want."

"It is unlikely that they will have any major technological breakthroughs in the short term, so we can't keep waiting."

"Relatively speaking, I have more confidence in Nanshan Technology. You have already developed the 5MT manual transmission technology and are researching automatic transmission technology."

"The automatic transmission we need is actually AMT in essence. As long as we add a key control component, TCU, to the manual transmission, we can achieve the same effect as the AT automatic transmission."

"The structure can indeed be greatly simplified, reducing the difficulty of development."

Zhu Jiansheng gave a detailed introduction to the needs of the Polytechnic Special Vehicle Factory.

This kind of situation where projects are delivered to your doorstep is rare in later generations.

But for many factories of this era, it is not uncommon.

My father-in-law has brought a team here for discussions, so Jiang Hui will definitely take on this task in the end.

The initial communication and explanation of difficulties are more about making the situation clear to others in the team.

Lest people think that Zhu Jiansheng is using public funds for personal gain.

"We can take this task, but the project development fee for the missile launcher needs to be paid in advance by the Polytechnic Special Vehicle Factory. In the future, we will only sell this product to the Polytechnic Special Vehicle Factory."

The gearbox on the missile launcher is destined to have no other customers.

Even if there are, they are not sold through Nanshan Technology.

Therefore, it is quite normal to let customers pay for the development fees.

Anyway, the Polytechnic Special Vehicle Factory is not very short of money now, so there is no need for Nanshan Technology to advance all the funds on its own.

Of course, the specific details will definitely not be discussed at such a conference, but will be handed over to the people below for confirmation and then submitted to the respective persons in charge for approval before implementation.

Taking this opportunity, Jiang Hui officially established Nanshan Transmission and separated the transmission business from Nanshan Technology.
