For China today, the engine is indeed a flaw. There is no problem with ordinary tank engines. After all, the 156 key projects that the Soviet Union aided China at that time included these. Tank production was provided by all technologies from beginning to end.

The same goes for aircraft.

As for ships, the Soviet Union's own ships were not very good. Until now, the US aircraft carrier was about to fill the entire world's oceans, and the Soviets had not started to build an aircraft carrier. However, their nuclear submarines were enough to compete with the United States, such as surface ships, that is, some large destroyers.

Khrushchev even believed that in the case of a nuclear war, the huge naval ships were just iron coffins floating on the sea, but the Cuban missile crisis made the proud polar bear realize that only underwater nuclear submarines and the lack of large surface ships with deterrence were definitely not a good thing for the Soviet Union.

As a result, the final work of a super surface ship like Kirov, a Soviet super surface ship, appeared.

The standard displacement of the Kirov-class missile cruiser is 19,000 tons, full load displacement of 24,300 tons, a total length of 252 meters, a waterline length of 0 meters, a width of 8.5 meters, a draft of 9.1 meters, and a maximum speed of 30 knots. Since it is nuclear-powered propulsion, it has an almost unlimited range.

This is a super cruiser that is mythical. The ship is classified as a cruiser according to conventional classification, but because of its incomparable firepower and super combat power, it was classified by Western military strategists as the "battle cruiser" that should have disappeared in this era. Therefore, it is also called the "Resurrection of the Battle Cruiser".

However, such war monsters were built by the Soviet Union only in 1968.

At the beginning, the Soviets could only build small boats. Therefore, the Republic also had the ability to build small boats and submarines. However, there was no technical reserve for large surface ships. This was the technology that the Western camp blocked the socialist camp the most severely.

If China wants to develop, Liu Yijiu thought seriously for a long time. The navy must be put to the end to develop.

Also, we must first ensure the security of the Republic's territory and airspace. Then we can consider the issue of territorial waters. This is a matter of no way. A powerful country like the Soviet Union can only conduct research in this area in the end. That is basically a national power.

Especially their aircraft carrier like Kuznetsov, before the collapse of the Soviet Union, there was only one such aircraft carrier, and Russia lasted until many years later.

Although the Varyag had been built 70%, it was eventually unable to be built due to the collapse of the Soviet Union.

When Russia's economic situation improved and politics stabilized later, when Russia and Ukraine's presidents hoped to continue to build the aircraft carrier, Makarov, the director of the Ukrainian Black Sea Shipyard, said to the two leaders in tears: "It is impossible to complete the construction of this ship again, unless he can give him a powerful Soviet Union. Let nine ministries of industry, fifteen franchised republics, tens of thousands of factories in dozens of industries and tens of thousands of industries provide them again..."

The powerful Soviet Union had no way to build this after its disintegration. Liu Yijiu naturally would not think that based on the current republic and the country did not have enough financial resources, he alone could allow the republic to build a powerful navy.

Therefore, he could only do various basic research honestly and slowly complete the supporting facilities.

Motorcycle engines, this is the most basic one.

Many years have passed since the founding of the Republic to the 21st century. All domestic equipment has heart disease. The J-10, J-20, and J-31, which made the Republic proud, are all foreign hearts! After more than 20 years of work, the Turbofan Ten still cannot fully meet the requirements for use...

Turbofan 15, that took more time...

Although the engine of a motorcycle is not in any similarity to the aircraft engine, this can cultivate a lot of industrial talents for the Republic.

Professionals in engines.

When people in District 1 were studying small engines, Liu Yijiu proposed to use all-aluminum for experiments, develop small motorcycle engines, and accumulate experience through this.

It is unlikely that China will start to study turbocharged engines at this time.

Liu Yijiu still doesn't know where the 2.0l turbocharged engines that Swedish Saab were originally developed in the base. Anyway, he has no time to get a button and has not asked about it.

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

"Director Liu, are we going directly on a four-stroke engine or a two-stroke? The engines made by all-aluminum will not have any bad effects due to insufficient aluminum performance?" Guo Hong still has a certain understanding of motorcycle engines.

This thing is not something you can do just by making it out.

It would be impossible for the Ninth Courtyard base to only provide them with some people and technology, and it would be impossible to produce a prototype during the National Day.

This is what they said at the beginning, "If you have difficulties, you have to go forward, and if you have difficulties, you have to go forward." Others say that you have to go forward to overcome difficulties. In order to express that they have always worked hard to strive for more advanced technology, people in this industry turned this sentence into creating difficulties without difficulties.

There are no difficulties, which is just ordinary technical difficulty for them. Creating difficulties means that they need to achieve higher results on this basis.

"Two-stroke and four-stroke have their own advantages and disadvantages. In the current situation, which one do you think do you think is more suitable for us?" This is also something that Liu Yijiu is struggling with.

Every time the engine crankshaft rotates, the engine that completes one working cycle with two strokes of the piston reciprocating two strokes is a two-stroke engine; every time the engine crankshaft rotates two rotations, the piston reciprocating four strokes of the piston reciprocating four strokes is a four-stroke engine.

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

"Two-strokes are currently more suitable for us. They rotate smoothly, do not require valves, few parts, are easy to maintain, and are cheap; and the disadvantages are also obvious, with more fuel consumption, more lubricant consumption, and unstable slow speed..." Liu Yijiu explained what he learned. "Although the four-strokes work reliable and efficient, and have good stability. The speed range from low to high speed is large; and it also has a loss of air reflux like a two-stroke engine, which has a low fuel consumption rate, and can develop high-power engines, but the disadvantages are also obvious, with high cost and inconvenient maintenance..."

The advantages and disadvantages of both strokes are very obvious.

Liu Yijiu obviously doesn't want to waste too much money on it.

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

"What are you worried about? Do these engines require a lot of money? We have both engines, one for ordinary displacement, and the other for large displacement high-power engines..." Zheng Hao is now rich and powerful. Seeing that Liu Yijiu was so confused, he immediately said domineeringly with his chest out.

As a result, it attracted Liu Yijiu's attention.

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

Zheng Hao is a lunatic. He is so heartbroken for some money. Now he doesn't care about anything when developing technical projects, and doesn't ask what it is for, so he looks like a nouveau riche.

"What's wrong? Am I wrong?" Zheng Hao was stunned.

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

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

In Jialing Machinery Factory, Liu Yijiu and Zheng Hao stayed for five days before they went to the base. These days, they discussed the equipment they needed with the people in charge of Jialing Factory. Zheng Hao had even decided with them which relevant units to find the various parts and accessories they did not produce here to cooperate with.

They belong to the Ministry of Machinery 5. Based on the idea of ​​not leaving any other people's fields, each supporting unit is finally looking for it within the Ministry of Machinery 5, and it is much easier to deploy.

Zheng Hao is very smart in this regard.

It is obviously troublesome to find other subordinate units of the Ministry of Machinery Industry to provide supporting facilities. If you can't find them, you have to find their chief department, and then find relevant departments of the Ministry of Machinery to coordinate with them. In your own department, everything is easy to say.

"Xiao Liu, let's get two engines directly, isn't this the best? There are more choices in the future..." Zheng Hao has never figured out why Liu Yijiu disagreed with this matter.

Motorcycle engines don’t require much investment, and they can’t even cost one million.

They are about to have a billion.

It's really meaningless to be stingy like this.

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

Zheng Hao nodded affirmatively.

"Although it seems like a billion is a drop in the bucket for our base! But you have to think about how many projects there are in our base at present. The 336 rocket launcher must continue to be upgraded? There are three projects in the air defense anti-tank multi-function missile, and they also have to take into account the 2983 Factory. Don't you want to get 155 heavy artillery? Our base also has to get tanks and helicopters. These are all worth it? One billion seems to be a lot, but in these projects, they are nothing at all!" Liu Yijiu said to Zheng Hao with a serious face.

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