Super Weapon Swap System

National defense and security cannot be measured by money.

Submarine launched missiles, as the force of the second nuclear attack, are the last means of the five permanent members, and all countries attach great importance to them. However, for the Han country, it is unrealistic to want to build a large number of nuclear powered strategic missile submarines, and the state cannot put all its funds on it.

Therefore, the landing of huge waves is a low-cost secondary nuclear counterattack force. It is the most important force to move on the ground by relying on the missile launch vehicle and be ready to receive the instructions of the superior at any time to carry out strategic nuclear counterattack. This task is entrusted to the Second Artillery Force.

Compared with the trailer can only walk on the road, this off-road chassis can pass through any complex terrain, which is obviously a more effective way.

If it can be built, it can be said that it will add a solid shield to the national defense and security of the motherland. The significance of this ballistic missile launch vehicle cannot be overstated.

At the same time, because the missile launcher has high field mobility and can have variants, it is not useless to play a role in oil exploration and other fields.

Now, the North heavy truck factory has developed, and has become a famous heavy truck enterprise in China, with strong profitability. Therefore, even if the superior has no project approval and appropriation, relying on the factory's own funds, we should carry out R & D. after all, there is only a home in a country. If there is no strong motherland, will there be a strong enterprise?

In the old social era before the founding of the Han Dynasty, how many businessmen set up factories in China with the ideal of saving the country and wanted to revitalize the country?

Those ruling classes will strangle them because their existence is not in the interests of those big capitalists abroad. Only when the motherland is strong, will there be the prosperity of enterprises and the status of enterprises in the world. Therefore, even if you are the largest in the world, you must not forget your strength because of the motherland behind you!

It is an unshirkable responsibility to contribute to the motherland.

Now, Qin Guan's saying makes everyone move. Yes, national defense and security are the responsibility of enterprises. We must not care about the gains and losses of enterprises. Now, we must do it.

"Brother Guan, with the capital and strength of our factory, we can complete the imitation of this off-road chassis." he ribala said: "but now we still have many problems. For example, should we copy its engine as it is?"

The transmission, rear axle and chassis should be copied as they are. There is absolutely no problem. Relying on the existing processing capacity of Beifang Industrial Company, there is no problem with these big guys, mainly the engine.

The service life of military vehicles and engines is not long, among which the most representative is the tank engine. The tank diesel engine has small volume, high power, high bearing bush specific pressure and intake pressure, and has strict requirements for the mechanical load and thermal load of the engine.

In this way, the high-power operation of tank engine is at the cost of high degree of reinforcement, short service life and high purchase price.

For example, the common engine of 59 tank can output more than 500 horsepower, but it can only use 500 motorcycle hours, and the price is as high as 1 million yuan.

In contrast, the largest diesel engine of the current North heavy truck can stably output 400 horsepower, and the price is about 100000 yuan. At the same time, in terms of working hours, needless to say, 500 hours and 5000 hours are less. If it is well maintained, 50000 hours will be fine.

Of course, after 500 motorcycle hours, the diesel engine of the tank is not immediately scrapped and can no longer be used. After it is discharged from active service, it can still continue to work for 2000 to 3000 hours in oil drilling, geological survey and other fields by reducing its power.

The tank diesel engine with high quality standard, high power, small volume and light weight will naturally be welcomed by local units.

Now, this off-road chassis, although he ribala has not been disassembled, also knows that it must use a military diesel engine, and its service life will not be very long.

For our own side, simply, we can take the tank engine directly. The improved tank engine can output 600 horsepower, which is not a problem. The most advanced main battle tank, which adopts the imitation Hans tank engine, can stably output more than 1000 horsepower.

However, the chassis in front of us is obviously the vehicle chassis. For a car, if the engine is overhauled in 500 hours, it is definitely not cost-effective.

This is how to choose. For Xiong people, they may not care about life expectancy, but in the Han country, it is absolutely impossible not to consider life expectancy.

"The diesel engine we have at hand can already output 400 horsepower," Qin Guan said. "If we expand the cylinder, can we make the power reach 650 horsepower?"

At present, this project only serves the country. However, if this project drives the technological progress in relevant aspects, it will make another leap in the heavy truck technology of Han country and become the leader of the whole world.

Qin Guan supports the civil engine. If the civil engine can output 650 horsepower and ensure the advantages in the field of civil engine, such as economy, low fuel consumption and long service life, it will definitely drive the heavy truck industry to take off. Heavy truck field, of course, also needs high-power diesel engine.

It can be seen from later generations that in the 1990s, heavy trucks generally had more than 200 horsepower. After 2000, they began to move towards more than 300 horsepower. After that, more than 400 horsepower became the mainstream. When Qin Guan left the parallel world, the leading heavy truck had reached the power system of 500 horsepower.

High horsepower, high speed, high timeliness, and fuel saving. Similar to the vegetable transportation and express industry, such a power system is needed. The driver can drive with less effort. Like a car, the heavy truck will come up at a high speed with one foot on the accelerator.

When the horsepower is small, it is an old cow and an old car, slowly and leisurely.

Take this opportunity to get a high-powered engine out?

In this way, if you want to build mining vehicles in the future, you can use them. If you want to build large vehicles, you can use them. It can be said that high-power engines are still necessary as technical reserves, which is also a project reflecting the technical strength of a car factory.

The simplest way to improve the power is to expand the cylinder.

At present, the main engine of domestic heavy trucks is the WD615 diesel engine imitated by Steyr. This diesel engine has six cylinders in line, the cylinder diameter is 126mm, the stroke is 130mm, the single cylinder displacement is 1.5L and the engine displacement is 9.726l.

At the beginning, it was naturally aspirated. Through exhaust gas turbocharging and supercharged intercooling, the power was increased. The current 400 horsepower model is the one with the largest power.

On this basis, if the cylinder diameter is expanded and the displacement is increased, the power can be further increased.
