"It's really emotional to come here all the way." Qin Zhenhua said: "I have seen the great rivers and mountains of the motherland, and I have also seen some ugly phenomena."
"Yes, Director Qin, since we have all come to Hainan, we might as well celebrate the New Year here." A leader said to Qin Zhenhua: "You can also see the scenery here. If there is any defense exhibition in the future, we will also
It can be carried out in Hainan to boost the economy here."
This sentence was a joke, but Qin Zhenhua was very serious: "There is no need to do this. We can only rely on ships to come here. The transportation cost is too high. If we can build a bridge and drive the equipment directly, it will be almost the same."
"Look, do you see it? If we don't build a bridge here, how much economy will be wasted." The leader said to a local leader with a smile.
"Well, building bridges is in the plan and will definitely happen in the future, but right now, we are building a free trade port and we can't get the funds yet."
"It seems that it is still inappropriate to establish a trade port here and transport it to the mainland. It also requires an additional shipping line."
Several people were chatting and talking about these topics.
"We also have our advantages. For example, our geographical location is the most southerly, so our new space launch base was chosen here. Do you want to go and take a look?"
There are three satellite launch bases in China, of which the Jiuquan Satellite Launch Base is the largest and the only manned space launch base in the country. The other two bases are backup and do not have many launch missions.
However, for satellite launches, it is also important to use the speed of the earth's rotation, so the closer to the equator, the more advantageous it is.
In this regard, Lao Maozi is the most disadvantaged, because Lao Maozi has no land to the south at all. They can only launch from high latitudes, wasting more fuel. Although the country initially chose Jiuquan, but now, with the new generation
In the development of manned spacecraft, the space launch base in Hainan has also been constructed.
Qin Zhenhua is very interested in this.
"Of course I have to take a look. Our aerospace technology is also very advanced. The new generation of manned spacecraft seems to have very advanced performance."
"Of course. We used to launch manned spacecraft using the Long March 2 rocket, which could only launch a spacecraft of about ten tons and provide the ability for three astronauts to enter space. Now, the new generation of Long March 5 rocket has
After being developed, the near-Earth carrying capacity has been increased to 25 tons. The new generation of manned spacecraft is already more than 20 tons and can carry up to seven astronauts."
"Seven astronauts are on the same level as the space shuttle!" Qin Zhenhua said with emotion.
"Director Qin, you are not only proficient in tank technology, but you also know a lot about aerospace!"
"Of course, the aerospace aspect has a lot to do with our tanks. Our newly developed data link system and our positioning system are all inseparable from aerospace. By the way, rockets and spaceships are also produced here.
Of?"
"That's not true. Rockets and spaceships are produced domestically and then transported directly by ship. This is also our advantage. Our launch site is next to the sea, which can be easily transported. The previous Long March 2 rocket was
When transported from the production factory to the launch base, it can only be 3.35 meters in diameter, which facilitates railway transportation. Our new Long March 5 rocket has a core diameter of five meters. In this way, it can load more fuel and achieve more
Big launch weight. Let’s go, Director Qin, go over and take a look.”
"Okay." Qin Zhenhua agreed happily.
In this way, the group of people drove along the coastal road and soon arrived at the launch base under construction on the seaside.
Some rooms have been built, and one of them has been turned into a special exhibition hall. Qin Zhenhua looked at the models placed inside with great interest.
When he saw the models of Long March 2 and Long March 5, Qin Zhenhua immediately felt the huge gap between the two.
The height of the Long March 2 is not much different from that of the Long March 5. However, the diameters of the two are different. It can be seen at a glance that the Long March 5 is fatter.
"In our aerospace industry, Long March 5 is called Fat 5 because it looks too fat." The person in charge here introduced to a group of leaders: "In the field of rockets, the aspect ratio cannot be too large, otherwise
It will cause severe flutter during flight. In the past, we could not develop rocket engines with high thrust, so we could only pile up the length. Now, we have advanced rocket engines and can develop horizontally."
"That one looks bigger." Qin Zhenhua pointed at a model and said.
"Yes, that is the Long March 9 rocket. It is a new generation of heavy rocket in our plan. Its core stage has a diameter of ten meters and a height of more than one hundred meters. In this way, the near-earth carrying capacity can reach 140 tons.
At this level, in addition to launching a space station, it can also conduct deep space exploration and prepare for the establishment of a lunar base in the future."
"Our aerospace technology has developed too fast." Qin Zhenhua was still immersed in the data just now. Long March 2 has a near-Earth launch capacity of ten tons, Long March 5 has a near-Earth launch capacity of 25 tons, and Long March 9
, the near-earth launch capacity is 140 tons, which is amazing.
"Yes, our aerospace technology has finally caught up." The person in charge said: "In the last world, when the United States and the Soviet Union were competing for hegemony and landing on the moon, the American Saturn V rocket had a near-Earth carrying capacity of more than 100 tons. The Soviet Union
The Energy rocket before it disintegrated was also capable of launching more than a hundred tons of payload, and we have finally caught up with them until now."
Speaking of this, the person in charge still felt a little emotional. Since the founding of the country, in order to protect its own security, it began to study ballistic missile technology. Later, the Dongfeng-5 intercontinental ballistic missile transformed into the Long March launch vehicle.
Years of development were very slow. It was not until the last two or three decades that the country's economy developed and rocket technology began to advance significantly.
It’s not easy to finally catch up with the world’s aerospace powers and join the top three in the world’s aerospace industry.
"Can these rockets of ours go to participate in exhibitions abroad?" Qin Zhenhua thought of something. He had already started planning to go to Europe to participate in defense exhibitions. Our own rockets have developed so fast, so it would be better to just take these rockets to participate in defense exhibitions.
It's a great way to show off the progress of our country's aerospace technology.
"Going to participate in an exhibition abroad? Of course you can, that would be great." The person in charge was very excited.
