In 1980, the work of the giant wave ashore began, and at this time, the underwater live fire of the giant wave in the nuclear submarine was already considered for transfer to a land-based model even before it began.

Unlike the previous Dangfei-3, this missile is a solid ballistic missile, so it is required to integrate as many systems as possible into an integrated launch vehicle. In order to achieve this goal, the relevant departments of the space system have carried out a lot of hard work.

The equipment on the ground is quite important, and it is necessary to complete various operations such as missile storage, protection, transportation, transshipment, head-body docking, erection, gas supply, power supply, testing, aiming, launching, and launch control, and launch the missile as required. At the same time, because it is necessary to run around on the highway, it is necessary to carry out high temperature, high humidity and rain tests, road transportation tests, instrument and equipment working life tests, standby tests, emission tests in low temperature environments and windy environment tests, etc.

Due to domestic technical limitations, at that time, although there were ideas, it was absolutely impossible to create a special integrated off-road vehicle, so it could only be used in the way of semi-trailers.

A variety of functions such as transporting, erecting and launching missiles are assembled on the trailer, which reduces the technical difficulty, and the trailer has a special launch canister on it, which is welded with aluminum alloy to reduce the weight, and due to the need for various tests, various openings are made on it.

So, judging from the appearance, the missile launcher with the tail towed does not look like a missile at all, but rather like a boiler.

Of course, this gives it better concealment, and it usually drags missiles around, even if it is discovered by reconnaissance satellites, and I think it is dragging a boiler.

Don't look at the backward shape of this boiler, but it is a very advanced device in China.

For example, the temperature of the environment used in missile combat has a wide range of changes, and there are too many openings outside this boiler, which is easy to dissipate heat and fill air, etc., and the internal missile needs to be kept at about 20 degrees Celsius at all times, so the inside of this launch canister has a special high-power air-cooled semiconductor temperature control system, that is, it is with air conditioning.

For another example, at the time of launch, the gas temperature is more than 2,000 degrees, but when it is launched, the launch canister cannot be burned out, nor can the tail of the missile be burned out, so there is a special cooling scheme for centralized water injection, which reduces the gas temperature from more than 2,000 degrees Celsius to about 200 degrees Celsius in tens of milliseconds.

As for the straightening of the launch canister after erection, the leveling of the hull, the 360-degree rotation of the entire launch device, and so on, it goes without saying.

After repeatedly tossing for so many years, at the same time, the Hanyang factory is also supporting the tractor, at that time, a machine factory has not yet introduced the Mercedes-Benz heavy truck project, and it can not be counted on, so the use of the Hanyang factory tractor is the only available option.

Now, although Mercedes-Benz heavy trucks are technologically advanced, since they have used Hanyang tractors, a lot of improvements have been made and a lot of equipment has been installed, so it is impossible to switch to Mercedes-Benz heavy trucks.

"It's a pity that with traction, you can't always have off-road ability." Huang Lao said.

This is one of their defects, because the technology is limited, so they can only use a trailer, since they use a trailer, don't expect to run into the field, they can only maneuver on the road, which does not meet the demand.

This time, they brought in the Scud missile launcher, and they also had great expectations, and they were eager to quickly learn its technology, and then improve it, and make a big guy.

Qin Zhenhua nodded, for the time Fan Gui said, five years to understand the technology, five to ten years of research and development by himself, I don't think it is too long, if you start from scratch, these times are not long, after all, you still owe too much debt.

The West does not have these technologies, because the Western road network is too developed, there is almost no non-paved road, there is no such demand, and the main technology comes from the Soviet Union, in the vast land of Siberia, those off-road vehicles, can be galloped at will.

Now, Huang Lao has high expectations for this missile launcher, and there are many reasons that cannot be said, the huge waves come ashore, the party fee 21, these are some of them can be said, as for what cannot be said, of course, it is a bigger guy than the party fee 21, which is also under development, the party fee 31, the party fee 41, especially the big guy codenamed 41, that is planned to replace the party fee 5, as an intercontinental missile.

As for the imaginary enemy, it is also conceivable.

Those big guys all plan to use solid rockets and mobile deployment, so that the second strike capability will be strong, after all, the eastern powers have announced that they will not be the first to use nuclear weapons, so they must have a strong counterattack capability.

Those big guys, if they want to launch in a mobile way, it's not convenient to take the road, after all, they are too big, and they need the same multi-axle big guys as the Soviets!

Trailers, okay?

"yes, that's a problem." Qin Zhenhua also frowned, helped the other party think of ideas, and quickly thought of something, and said: "If we also install a power system on the trailer, how about it?" ”

Trailer, with power?

Qin Zhenhua: Isn't this? Now in this day and age, who has ever seen a trailer with power?

"Just like a mining car, using electric drive, behind our trailer, those wheels, also become electrically driven, so that the whole car has power, of course, it is also possible to use hydraulic power to drive, so that if you encounter the wild, you can also increase the chance of getting out of trouble."

The train runs fast, all depends on the headband, this kind of tractor is the same, in later generations, heavy trucks are in the form of trailers, because this is the most convenient, as long as there is strength, you can pull the tow bucket away, even if it is hundreds of tons can walk, but once you encounter the uphill or something, there is no way.

What if the trailer is also powered? The wheels can rotate on their own, which increases the ability to get out of trouble.

Fan Gui was there, and he also frowned: "No one has ever done this thing, and besides, if you do it like this, the driver can't drive it!" ”

When he said this, he stopped, because someone had already hurried in, a middle-level cadre from the Antai factory, mainly responsible for reception and other projects.

Seeing him like this, I thought it was a guest of those pyramid countries, what was wrong with visiting here.

"Factory director, Sanjiang Factory, asked us for assistance, they have a car in the river."
