Super military empire

"There is no problem with all cooperation. Of course, for some things, our Ninth Academy has to take the lead. As for the subsequent results, it doesn't matter if they are announced to the outside..." Liu Yijiu is now speaking very well.

For such things, he would not refuse at all.

The only thing is to control the technological development in the hands of the Ninth Institute, so that the research progress of the project and the research funding will not be messed up.

"As for the rocket, it was improved by using the Long March 3, except that the gto (geosynchronous transfer orbit) carrying capacity has been increased to 2.65 tons, the flight capacity and the docking performance of the satellites and arrows have been improved. At the same time, the satellite It is sent to a low-inclination orbit or a super-synchronous transfer orbit to increase its service life... that is to say, the new Long March III has greater thrust, stronger carrying capacity, and faster flight speed..."

For the Rockets, Qian Xuesen is personally responsible.

The relationship between this system plan is too great, and the impact is very far-reaching.

There must be no mistakes.

Before, there had been a Long March 3 rocket, but its performance was not very good. It could only send a load of about one and a half ton to the orbit.

The satellites of the Beidou system have more functions. When the materials are not advanced enough, the manufacturing process is not very good, and even the foundation is not too strong, to achieve more powerful functions, the satellites can obviously only be made larger.

In this way, higher requirements are put forward for the carrying capacity of the entire rocket.

"What about engines?" Liu Yijiu is most concerned about engines. Although aerospace engines are not as demanding as aero engines, they also have a very critical position in the aerospace field.

Control systems, navigation systems, etc., are not even as critical as the engine.

"The engine is not a problem. Especially with the new high-temperature alloys and aluminum alloys, our engine performance has more than doubled compared to before. It is precisely because of this reason that our Long March No. 3 A appeared. Burning. Higher efficiency, more reliable quality..."

"What if this kind of engine is used in our intercontinental strategic missiles?" Liu Yijiu's question is like this

Rockets and missiles are basically the same principle.

The only difference is that the missile needs to return to the atmosphere after entering outer space to attack distant enemies.

"At present, we need to wait for further data accumulation!" Qian Xuesen nodded and said to Liu Yijiu, "I know what you think, there is not much difference between missile and rocket technology itself. However, if you want to achieve Dongfeng- 6 and Dongfeng-7, the current technical conditions are not enough. Unless we can make greater breakthroughs in material technology and design..."

The design range of Dongfeng-6 needs to reach about 14,000 kilometers, while Dongfeng-7 needs to reach 19,000 kilometers or more!

The situation in China is different from the Soviet Union. The Soviet Union is in the far north, close to the North Pole. As long as their missiles have a range of 14,000 kilometers, they are enough to attack most of the world.In particular, most of the people in the world are in the northern hemisphere, and those countries in the southern hemisphere are not regarded as enemies by them!

Launching missiles from the territory of the Soviet Union, the missile can attack by flying in any direction through the North Pole.

China can't. To attack any place in the world and make a missile fly over the North Pole, it needs a range of several thousand kilometers more than the Soviet Union.

Of course, China can also attack directly along the line of latitude or in a straight line.

No matter which mode you choose, you need a longer range of the missile.

The range of 19,000 kilometers is a conclusion drawn by domestic experts after years of demonstration.

This project was cut off in the 1980s, and then, in the 21st century, after many breakthroughs in aerospace technology, China continued to invest in this project, and finally came up with the ability to send express delivery to any location in the world. A super killer like Dongfeng-51!

In fact, the east wind with a range of 19,000 kilometers is too wasteful.

******** The biggest enemy is only the United States and its allies, and even Europe will not be on the same front with the United States in the end.

However, in this play, Director Liu's purpose is not to frighten anyone, but for the moon landing project.

As long as this missile is modified, it can become a civilian rocket, with faster speed and stronger push ability, and the speed of human beings to the moon will be greatly increased.

Otherwise, such a money-burning project would have long been abandoned.

"This is not anxious. Anyway, we have time!" Liu Yijiu said with a smile.

Then continue to listen to the introduction of the performance of the Long March 3 A, as well as some special designs.

Especially when compared with Long March 3, it can be more clear.

"Compared with the Long March 3, the improved Type A, due to its more flexible and advanced control technology, can carry out large attitude adjustment and orientation of the payload before the separation of the satellites and arrows, and provide an adjustable satellite rotation rate. It has strong adaptability..." Qian Xuesen introduced meticulously.

Liu Yijiu also listened very carefully.

After all, the performance of this Long March 3A rocket has even surpassed some aspects of the Long March 3B.

The main improvement is the control system because of the more advanced chips provided by the Ninth Institute.

"Except for the control technology and other aspects, this is not much different from the improved design of the prototype, but the third stage fuel has been improved, using more efficient liquid hydrogen and liquid oxygen..."

On the subject, it still didn't go beyond much.

"This is no problem. More advanced models need to be improved in the future. Our Beidou system needs to send satellites to a higher orbit." Liu Yijiu nodded."No matter how good the design is, we have to wait until after launch to know whether our design is okay. How to improve, if it is more advanced..."

No need to say this, everyone is clear.

After the introduction, Liu Yijiu stayed at the Ministry of Aerospace Industry for another night, preparing to go with the aerospace crew early the next morning.

When it comes to the Beidou system, the military also attaches great importance to it. After all, the United States and the Soviet Union have built satellite systems covering the world. China is always under their noses. Any good things or troop movements can be clear to them. To understand.

Only if you have your own satellite system can you have the power to counterattack.

"Papa Qian, what happened to the Type 31 that we delivered? Our guided missile battleship, but just waiting for this stuff." After coming down, Liu Yijiu suddenly asked him when they were with Qian Xuesen.

Originally, this matter was the most confidential thing, but Liu Yijiu had the right to know.

The military allowed him to mount this thing on the guided missile battleship.

"It has always been moving forward in a continuous and stable manner. There is still some work that needs to be done in order to carry out a test launch. After all, there is a big difference between a large solid fuel rocket engine and a small one. In this respect, is the technology breakthrough very slow? Of course, according to the current progress, a high-ballistic test launch will be possible around May next year. The Long March 3A uses many of these missile technologies. If we successfully launch this time, it will prove that the Dongfeng-31 technology is reliable. of……"

"Isn't the long 3 armor made of liquid?" Liu Yijiu asked suspiciously.

"Except for the difference in propulsion fuel and engine, there is no problem in control technology. Otherwise, do you think the improved version can be completed so quickly? The biggest problem passing by is that the on-board system development of these missiles cannot keep up. Very much. It may wait until our missile is completed, but there is no heavy vehicle that can be carried..."

"..." Liu Yijiu's mouth twitched immediately.

Anyway, they don't plan to get involved in this area.

The development of such heavy-duty trucks requires a large amount of engineering and technical difficulties. At the same time, it is also very difficult for them.

Qian Lao's words immediately reminded him that during the military parade in the 99th century, Dongfeng-41 itself was prepared and common, because the on-board system was immature and eventually gave up.

It can be said that the development work of Dongfeng-41 and Dongfeng-31 is not too different.

The two types of strategic missiles have different ranges and perform different accounting tasks.

"You don't plan to intervene here?" Qian Xuesen was a little strange. Every time there was such a problem, Liu Yijiu would take it over.He said this because he hoped that Liu Yijiu could help solve these problems.

The funding for aerospace is too tight.

Liu Yijiu immediately shook his head, "It's not that I don't want to, but that we really can't increase these projects. The personnel aspect is a problem, and if we intervene, many units will eventually be lost because they have no business. Demolished. This is not a good thing. In recent years, because of the existence of the Ninth People's Hospital, many military factories have gone bankrupt or completely restructured..."

Qian Xuesen was also silent.

In order to develop the economy in the past few years, the country’s basic domestic production capacity has been insufficient, and it has to reform the military system and put it on the market.

The benefits of this are obvious. After the development of domestic basic industries, the production capacity and quality of production have improved a lot after the military industry reform.

But it also caused another problem, that is, the lack of military production capacity.

Once war breaks out, it will be very dangerous.

"We can launch a train. The total length of Dongfeng-31 is only more than ten meters, and the total length of Dongfeng-41 is less than 17 meters, so the train can be put down completely..." Liu Yijiu just didn't want to build a truck anyway."Of course, road maneuvering is necessary, and this space-supporting unit should still work hard. This time we gave the five billion yuan of funding, also has this consideration."

Seeing Liu Yijiu's sincere attitude, Qian Lao didn't force him.
