Super military empire

For China now, the engine is indeed a flaw.Ordinary tank engines are still no problem. After all, these were included in the 156 key projects that the Soviet Union aided China. Tank production was provided with all technologies from start to finish.

These aspects of the aircraft are also.

As for ships, the Soviet Union’s own ships are not very good. Up to now, American aircraft carriers are almost covering the entire world’s oceans, and the Soviets have not started building a single aircraft carrier.But their nuclear submarines are enough to contend with the United States, surface ships or something, that is, some large destroyers.

Khrushchev even believed that in the event of a nuclear war, huge naval ships were nothing more than iron coffins floating on the sea. The Cuban missile crisis made the proud polar bear realize that there are only underwater nuclear submarines and lack of deterrence. Large surface ships are definitely not a good thing for the Soviet Union.

Ever since, Kirov, the final work of the super surface ship at the peak of the Soviet Union, appeared.

The Kirov-class guided missile cruiser has a standard displacement of 19,000 tons, a full-load displacement of 24,300 tons, a total length of 252 meters, a waterline length of 230 meters, a width of 8.5 meters, a draft of 9.1 meters, and a maximum speed of 30 knots. Due to nuclear-powered propulsion, it has almost unlimited voyage.

This is a mythical super cruiser. The ship is classified as a cruiser according to the conventional classification. However, due to its incomparable firepower and super combat power, it was classified by Western military experts as the one that should have disappeared in this era. "Battlecruiser" ranks, so it is also called "Resurrection of Battlecruiser".

However, the construction of such a war monster was only started by the Soviet Union in 1968.

The Soviets were only able to build small boats, so the Republic also had the ability to build small boats and submarines.But for large surface ships, there is no technical reserve at all. This is the most severe technology that the Western camp has blocked against the socialist camp.

If China wants to develop, Liu Yijiu has been thinking about it for a long time. The Navy must put the development at the end.

Also, the security of the territory and airspace of the Republic must be ensured before consideration of territorial waters.There is no way to do this. A powerful country like the Soviet Union can only conduct research in this area at the end.That is basically a national effort.

Especially for their aircraft carrier like Kuznetsov, before the Soviet Union collapsed, only one such aircraft was built, and Russia has only such an aircraft carrier until many years later.

As for the Varyag, although 70% of it had been built, it could not be built again due to the collapse of the Soviet Union.

When the economic situation in Russia improved and the politics stabilized, in the face of the presidents of Russia and Ukraine who hoped to continue to build the aircraft carrier, Makarov, the director of the Ukrainian Black Sea Shipyard, shed tears at the two leaders. He said: "It is impossible to complete the construction of this ship, unless we can return to him a powerful Soviet Union, nine ministries of industry, 15 republics, dozens of industries and tens of thousands of factories. Support them again..."

After the disintegration of the powerful Soviet Union, there is no way to build this. Liu Yijiu naturally does not think that on the basis of the current republic, when the country does not have sufficient financial resources, he alone can allow the republic to build a powerful navy. .

Therefore, he can only do all kinds of basic research honestly and slowly complete the supporting facilities.

Motorcycle engine, this is the most basic.

Many years have passed since the founding of the republic until the 21st century. All domestically-made equipment suffered from heart disease.The J-10, J-20 and J-31 that make the Republic proud are all foreign minds used!Turbofan 10, after more than 20 years, there is still no way to fully meet the requirements...

Turbofan fifteen, that also took more time...

Although there is no similarity between the motorcycle engine and the aero engine, this one can train many industrial talents for the Republic.

Engine professionals.

When he knew that people in the first district were studying small engines, Liu Yijiu proposed to use all-aluminum materials to test and develop small motorcycle engines, so as to accumulate experience.

It is not very possible to expect domestic research on turbocharged engines at this time.

As for the 2.0l turbocharged engines being developed by the Swedish s+b Saab company originally in the base, Liu Yijiu still doesn’t know where they are. Anyway, he doesn’t have the time to get them. Ask more about this.

Now, the engine must be used, and they must work hard on it.

"Director Liu, do we directly use the four-stroke engine or the two-stroke engine? Will the all-aluminum engine have any bad effects due to the insufficient performance of the aluminum material?" For motorcycle engines, Guo Hong still has Certainly understand.

This thing is not just made out of it.

If the Ninth Academy only provided them with some people and technology, it would be impossible to produce prototype cars during the National Day.

This is what they said at the beginning, "If you have difficulties, you must go up, and if you have difficulties, you must also go up with difficulties."Others say that they have difficulties to overcome difficulties, and people in this industry, in order to show that they have always worked hard towards more advanced technology, they have changed this sentence to create difficulties without difficulty.

There is no difficulty, which is ordinary technical difficulty for them.The difficulty of creating means that they need to achieve higher results on this basis.

"Both two-stroke and four-stroke have their own advantages and disadvantages. Under the current circumstances, which one do you think we use is more appropriate?" This is also Liu Yijiu's entanglement.

Every time the engine crankshaft rotates one revolution, the piston reciprocates two strokes to complete a working cycle. The engine is a two-stroke engine; every time the engine crankshaft rotates two times, the piston reciprocates up and down four strokes to complete a working cycle is a four-stroke engine.

The working cycle refers to the working process of the engine composed of intake, compression, combustion expansion (work), and exhaust stroke.

"The two-stroke is currently more suitable for us. It rotates smoothly, does not require a valve, has fewer parts, is easy to maintain, and is cheap; but the disadvantages are also obvious, such as high fuel consumption, high lubricating oil consumption, slow speed and unstable..." Liu Yi Jiu told what he had learned."Although the four-stroke is reliable, efficient, and stable. The speed range from low to high speed is wide; and it also has the return loss of blow-by gas like the two-stroke engine, low fuel consumption, and it can develop high-power engines, but the disadvantages are also obvious. Yes, the cost is high, and the maintenance is inconvenient..."

The advantages and disadvantages of the two stroke engines are very obvious.

Liu Yijiu obviously didn't want to waste too much money on this.

He wants to spend money on helicopter engines and car engines, and even their missile engines, all of which have to be paid.

"What's the entanglement, do these engines need a lot of money? We have two kinds of engines, one with normal displacement, and the other with large displacement, high-power engines..." Zheng Hao is now rich in money. Liu Yijiu was entangled, and immediately said with a domineering chest.

As a result, Liu Yijiu's eyes rolled.

"We don't decide on this matter for the time being. You will get other aspects first. I will discuss it with other experts after I go back..." Liu Yijiu did not say that both engines were made.

Zheng Hao is a crazy guy. For a little gas, he is heartbroken. Now he is developing a technology project and he doesn't care about anything at all. He doesn't ask what the development is for, he begins to look like a nouveau riche.

"What's the matter? Did I make a mistake?" Zheng Hao was stunned.

Liu Yijiu ignored him, but continued to discuss some structure and appearance design of the motorcycle with Guo Hong.

And participate in the upgrading of technical equipment in the factory.

In Jialing Machinery Factory, Liu Yijiu and Zheng Hao spent five days before they went to the base.These days, they have discussed what kind of equipment they need with the people in charge of the Jialing factory, and Zheng Hao has even finalized with them which related units should be used for the various spare parts they do not produce.

They belong to the Fifth Machinery Department, and in line with the idea that the fertilizer does not flow to outsiders' fields, in the end, all supporting units are found inside the Fifth Machinery Department, and it is much easier to deploy.

Zheng Hao is very shrewd in this regard.

It is obviously troublesome to find other units affiliated with the Ministry of Machinery Industry. It is impossible to find them. You have to find their official department, and then find the relevant department of the Ministry of Machinery Industry to coordinate with them.In my department, everything is easy to say.

"Xiao Liu, let's get two engines directly. Isn't it the best? There will be more choices in the future..." Zheng Hao has not figured out why Liu Yijiu disagrees with this matter.

Motorcycle engines don’t require much investment at all, even less than one million.

They will soon have a billion.

It's really meaningless to dig like this.

"Do you think we have a lot of billions?" Liu Yijiu asked Zheng Hao speechlessly.

Zheng Hao nodded affirmatively.

"Although it seems that one billion is very much, it is just a drop in the bucket for our base! But you have to think about how many projects we currently have in the base. The 336 rocket launcher must continue to be upgraded? There is the air defense and anti-tank multi-function missile. Three projects, and you have to take care of the 2983 factory, don’t you want to get 155 heavy artillery? We have to get tanks and helicopters in our base. These are not money? One billion, it seems a lot, in these projects , It's nothing at all!" Liu Yijiu said to Zheng Hao with a serious face.

"If we don't have money, can't we get it from the Americans?" Zheng Hao said disapprovingly.

"Do you burn too much money as an American? How many things do we still need? If we can get the technology on that bomber out of their hands, it won’t be a problem. The problem is that we can do it. Come out?"
