C1767 The Advantage of Solid Rockets

For a rocket, it's not like the more levels there are, the higher the level. In order to explore space, a rocket is needed.0

The performance of rockets could be measured by a concept called "mass ratio." This referred to the ratio of the original mass of a rocket to the final mass of a rocket.

Simply put, the load that a rocket had to transport at the end was certain. However, the shell of a rocket occupied more mass. Under such circumstances, the best way was to reduce the weight of the shell. In the process of flying, a part of the shell would be thrown off after flying for a while. This would increase the final speed of the rocket.

Therefore, the current rockets were all multi-level. However, the higher the level, the better. If there are too many levels... The connection between each level and the separation mechanism would also increase correspondingly, which would affect the overall strength of the rocket. It would also bring some complicated technical problems.

Therefore, generally speaking, rockets were at level two or three. For example, Long-range rockets were currently at level two. The Long March 2 was at level two and was used to launch low-Earth orbit satellites. The Long-range Conquering Three was at level three and was used to launch synchronous satellites.

However, along with the improvement of rocket technology, it was also starting to develop single level rockets. For example, the Long March 5 series rockets that they were planning on using because of the advanced hydraulic fuel engine. They only needed one grade.

If they were to transport a large mass load, they would tie up a few boosters to form a one-and-a-half structure. If they were to use the synchronous orbit, adding another upper level, it would be enough to become two levels.

However, these were all liquid rockets, for solid rockets. Originally, his own thrust was not high. And... Consolidated rockets were different from liquid rockets. The medicine was directly stored in the shell. The more it burned, the deeper it went into the shell. If it was too long, the thrust would be insufficient. Therefore, he had to start up multiple rockets.

If he wanted to launch a small satellite, a multi-level solid rocket would be enough.

However, the higher the number of rockets, the longer they would be. If this continued, then the rocket would face another terrifying problem, which was resonance.

In the world, there were very few Level 4 liquid rockets. Just because it was too long, there would be a problem of mechanical resonance during flight, which would cause the rocket to disintegrate during flight.

"If our rocket is too long, will there be a problem?" Qin Guan asked.

Upon hearing Qin Guan's question, Elder Wang's face immediately revealed a surprised expression. "President Qin, you are indeed an expert in this field. That's right. If the rocket was too long, such a problem would occur. However, this also depends on the situation. Our solid rocket... Our solid rocket is destined to be small. For example, its total length is only 20 meters. If that's the case, the strength of the arrows won't be a problem. "

Rockets are all big. For example, the Long March 2. The total length is 50 to 60 meters. The Five Earth-Fire Rocket can easily be 100 meters long. But what about the small solid rockets now? If it was just a few hundred kilograms of load, then it would only need 20 meters of rocket.

Just as Elder Wang was speaking, Qin Guan had already left the Weapon Data Cemetery. He had read through the information regarding Changzheng No. 11. This kind of rocket was indeed quite small. The total length of the rocket was 20. 8 meters. The largest diameter of the arrow is 2.0 meters. Weight is 57 meters. 6 tons, the takeoff thrust was 120 tons, and the rocket's SSO load capacity was 400 kilograms. LEO's load capacity is 700 kilograms.

It could be said that this kind of rocket was very small, and it was completely prepared to launch a small rocket.

"There are many benefits to a solid rocket. We can even produce and store it in advance. When needed, the test will be done and it can be launched directly." Qin Guan continued.

The process of a liquid rocket was quite complicated. A single launch often required a few months of preparation, but what about a solid rocket? It would only take a few hours.

Looking at the potential launch Ballistic Missile, one would know that this kind of missile could be launched at any time. It was very convenient. In the future generations of Bear Country, they even directly used their retired Ballistic Missile to launch satellites.

Thinking of this, Qin Guan suddenly remembered. If it was this kind of small missile, then there was another benefit. It could be launched on an ocean platform.

In order to make use of the Earth's automatic rotation speed as much as possible, under Qin Guan's suggestion, he set up the fourth launch site on Hainan Island. This launch site was the southernmost part of the motherland. However, it was still not close to the south. The best was on the equator. Even if it was not on the equator, in the sea regions where they had already started to fill up the sea and build land... It was even closer to the south.

If it was a large-scale rocket, it would face problems like transportation. However, this kind of solid rocket wasn't afraid. It could be directly installed on the platform, dragged over, and launched.

"Elder Wang, so we can also conduct a launch experiment on the offshore mobile platform." Qin Guan said to Elder Wang.

The thrust of the small rocket was limited, and the speed of the rotation of the Earth was limited. If he could use it, he would have to use it as much as possible. Now that Qin Guan had said so, Elder Wang immediately understood Qin Guan's plan. He clapped his hands and said, "That's right. President Qin, what you said makes a lot of sense. We need to look for those comrades who are in charge of East Wind 21 and use their techniques as reference. We will be able to produce results very soon. "

In fact, the Long-March Eleventh rocket in the future was also determined by a combination of many factors. The technological level of this rocket had already surpassed the East Wind 31, or even the East Wind 41.

Elder Wang was serious. There was demand in the international market now. At the same time, it also had military significance when a war suddenly broke out. Or when there was a natural disaster, he needed to launch the Reconnaissance Satellite at the last minute. At this moment, the normal satellite launch site had a time limit. With a weather limit, it was very easy to cause trouble. But... This kind of small rocket was different. When stored, it could be used at any time. Furthermore, when needed, it could even be used without any launch site. When it was set up, it could be used to fight. In essence, it was no different from those mobile Ballistic Missile. This kind of convenience was not something that any other rocket would have.

This kind of rocket was worth a try.

Of course, the missiles of the army were not at all cost. If they wanted to occupy the civilian launch market with this kind of small rocket, it definitely could not be expensive. If it was too expensive... Then it wouldn't be able to occupy the market. It would still need to be low-cost.

There were a lot of challenges in this, but it was definitely worth trying. Rocket was definitely not just a project with a huge investment. It had to be produced!

Elder Wang was still seriously considering the details. At that instant, the Elementary Scholar came in and said to Qin Guan, "President Qin, Western Alliance has contacted us. Their market manager, Stephen Ike, is on a passenger plane. He intends to talk to us. "
