Chapter 331： The tank has a big heart (below)

Domestic tanks have always been trapped in the engine. The power is not big enough to make bigger and heavier. So for a while, it can only be five pairs of magic. Later, there was the 99 style, but it was still smashed by the engine. Now

The engine used in the Type 99 tank is a domestically produced 1200-horsepower diesel engine. Although the overall design is very advanced, there is still a certain lack of maneuverability.

It is not that there is no way to buy a high-power diesel engine from abroad, but the NATO countries headed by the United States collectively banned China in this field. Even if there are occasionally several civilian 1,500-horsepower engines, they are strictly restricted and should not be used for military purposes. This also makes the country have to make a big decision and must solve the heart problem of the tank. Guo

It took only a month or more for Tailai and Longfei to come up with a diesel engine series, which is absolutely ridiculous in the eyes of some people who knew this for the first time. Especially in the eyes of old experts who have been studying engines for a lifetime, this is simply a joke.

Again, doing learning is a down-to-earth thing, and doing research and development is equally true. A lack of foundation at a glance is definitely not a good thing. A series of designs can be produced in a month, so what do they do for those who have studied for decades?

Zhao Xiangbei asked these domestic diesel engine experts to come over and check them out. These experts did not deny them. Zhao Xiangbei said before, this is a choice of engines for our domestic tanks. If successful, it is definitely a good thing. They are all old experts who have dedicated their lives to the country. How can they not understand the benefits of success? Do not

However, in order to prevent Guo Tailai from cheating on this side, when they came over for acceptance, they all came with their own testing instruments. This is a responsible attitude, not for whom. In fact, Zhao Xiangbei did not tell these people at all. The engine designer was Guo Tailai. He only said that it was acceptance, and did not say who designed the design.

In the military industry group, there are so many things, and the confidentiality of the designers is too normal. Experts have become accustomed to it, and without a single question, they followed Zhao Xiangbei all the way to Guo Tailai, the small factory where they developed the engine.

When I saw such a simple factory, the hearts of several experts were half cold. Such a small township enterprise-level small factory may design and manufacture a small-displacement engine. The parameters may be excellent, but if you want to make a series from big to small, I am afraid the possibility and the Chinese football team. The next World Cup will be as low as the championship.

Not only that, but did not say a few words, the thin designer was taken away by a lieutenant colonel. Although there must be something important, but at this moment of acceptance, can you not stagger the time? So young designers, anyway, a few experts cool down a quarter of the heart and cool a quarter.

When Longfei enthusiastically greeted these old experts to start work, when they saw the real thing, only one quarter of the remaining hearts did not cool down, and once again cooled by one-eighth, only one-eighth of them remained.

How are the dimensions of these engines so small? According to the above description, the average of each type of displacement is much smaller than the same type. With such a small engine, how high horsepower and torque can be expected, isn't this a toss? also

Well, the experts understand the principle of Longfei's explanation, and they are relieved. At least these engine principles can be said to work, and they all work well. I dare not say how good performance is, but at least this is indeed a complete series. Military use may not have an opportunity, but in the civilian sector, such a small-sized engine, even if the power is lower, can adapt to many occasions. This can be said to be the only good news that came over today.

But since it is to be accepted, it will not be awaited, the instrument is ready, the commissioning is zero, and then the parameters of the engine are measured one by one. first

Starting from the smallest size, while the machine is connected to the dynamometer, several experts also watched several parameters of the engine provided by Longfei. Only a few glances, a few people laughed. In addition to the size is definitely no problem, the rest are all exaggerated. Such a small size, so much smaller than the domestically produced type, the power is even higher than 40%, how is it possible? can

When the first smallest engine's speed power torque curve came out, the faces of several experts changed. The parameters of Longfei’s young younger ones are not fake? Want

I know, this is the dynamometer that they bring with them, and they have never been manipulated. The power and torque measured in this way are not fake numbers, which is really amazing! "

Immediately, change that 1500 horsepower. "One of the experts is studying the tank engine. When you see this result curve, you can change the machine immediately."

The size of the 1500-horsepower 10-cylinder diesel engine is smaller than the 1200-horsepower used on the current 99 tank. If the power torque data is true, he would not imagine the 99-type tank to be replaced by this engine. What is the excellent performance. Measurement

The test did not let Longfei their helpers, all the experts brought by the experts themselves, that is, they are afraid of cheating in them. But now, they can't wait any longer.

The ten-cylinder diesel engine is running, and the motor on the dynamometer starts to rotate. As the speed rises, the console on the other side generates a series of rotational power torque curves. After half an hour, the detailed data was finally released, and at that moment the tank engine expert had already held the results curve that came out before and kept smashing.

Power of more than 1200 horsepower is certainly no problem, the low-speed maximum torque also exceeds the tank engine in active service, and now only wait for the highest power to be released, you can know the final result. When another expert gave him the final test result and saw the 1538 horsepower data above, he couldn't help but redden his eyes. nice

The German tank engine power is almost 1500 hp. For this reason, China has carried out the embargo and blockade of the diesel engine under this power. China has to use the 1200 hp engine to push the 99 tank out first.

Now, this 1500 horsepower engine is his own test, the data will not be a problem, the size is still so small, and fuel-efficient, it can be said that as long as the size is modified, you can directly use the 99 tank! Our tanks must have a big heart! "

Don't worry! Another young expert next to him looked at him like this. In fact, he felt the same feeling in his heart, but he still advised him: "There is also a 2000 horsepower, and wait until the test is completed and then have fun together!" ”
