Chapter 495

Xiang Qian chuckled. This time, he didn't hold it. The others below couldn't help laughing.

Chen Tong curiously asked: "do they know how big the TIANTI base is?"

"Shh..." Xiang forward and put up a finger.

"Next, we also invited Huayan company to participate. This time, we came with sincerity and became the construction company of the world's largest space base. This will make you a shining point in the history of the world." When the white elephant's representative has finished speaking.

Hans's representative stood up and asked curiously, "but the question is, so far, the TIANTI base is still confidential. How can you prove that you have surpassed the TIANTI base?"

"Our launchers will have two, heavy launchers. And we will develop a heavy spaceship within a year. Our own team is developing this project. If there is no problem, we should consume less than Huayan. The cost is lower. And it's faster to make it! "

Chen Tong whispered: "I'm not ashamed."

In the crowd of white hawk representatives a face of disdain, they smile with ridicule, whispering. Hoffman stood up and said, "as far as I know, the carrying weight of Huayan's spaceship is more than 150 tons, while the launching weight of the launching pad is 200 tons. The most important thing is that their spaceship is recyclable."

"Please rest assured that we will do it. As we all know, white elephant is also a big Aerospace country. Our space technology... "

Next, laughing again, Chen Tong asked in a low voice: "how did you say that?"

Xiang Qianjin shook his head, and the representative of Hans shook his head and sighed.

Next, I come to Huayan to speak. After all, it's half the host. This venue is also the place where Huayan often holds new product launches. Xiang Qianjin stood up and said with a smile, "I'm glad to meet so many colleagues in the circle. As we all know, Huayan is a small company. The competition in the world is so fierce. We Huayan have just come up with a plan, and then the white elephant will surpass us. So this project is ideal. We wish you success. For some special reasons, Huayan has a confidentiality agreement. We can't disclose all the data about TIANTI base. In addition, we can't disclose all the equipment in the base. Also, we are now starting the construction of Huaxu island. However, I can tell you that Huaxu island is a follow-up project of TIANTI base. It can't be built once, so we will continue to develop our follow-up development around TIANTI base, so that these bases can really benefit mankind. "

Xiang Qianjin talked with great eloquence, and all he said was to the end. People in the meeting hall listened very carefully, especially the construction of Huaxu island. Originally, many foreign media doubted this and that. Now they find that this is a space project, not a military one. This is the official announcement of Huayan. After all, it's really frightening for a company to build a man-made island at sea when an asteroid with a diameter of 600 kilometers exploded into a ring of Jupiter.

Xiang Qian explained and then came back to sit down. Geng Li said with a smile: "you are really bad enough to hurt others."

Xiang Jin just laughs and doesn't say anything. It's better not to talk much on this occasion.

The white elephant representative announced the construction site of the bidding. In terms of the surface area, it is indeed larger than Huaxia. But there is a problem, that is, the road facilities here are seriously backward, and there are extremely serious problems in the transportation of materials. The area designated by the white elephant is low altitude. Although low altitude and proximity to the equator do have the advantages of launching, the disadvantages are also very clear, that is, humidity, salt and alkali corrosion, which will have great obstacles to the construction of the base. In addition, the place is in the hilly and mountainous areas. That point itself is a very remote place. The construction conditions are really poor. In addition to the problem of the launching well, the white elephant chose a large-scale launcher, which can be changed to the inclined launcher. The launcher is very high, and there are many launching platforms in the base. Plus a concrete runway with a ski jump at the bottom.

I'm confused. What's the point? The purpose of such a long runway is very clear. This runway is 5000 meters long, and it has a ski jump take-off platform. However, I can't understand it. It's not going to be rocket propelled and fly out on this platform, is it? They don't think that Huayan used the technology of ski jump takeoff of carrier based aircraft to send the spacecraft to the sky, do they?

Geng Li blinked. He said in a low voice, "it's not this plan. It's not sick, is it?"

When Geng Ligang finished speaking, the representative of Gaul stood up and said, "no, this plan is not feasible. Let's put it this way. In theory, although it is possible to fly the spaceship from the ground with a very high thrust, you should know how much fuel it needs.""So we're going to use catapults. Use the super large catapult to accelerate the aircraft, and then raise the speed to a certain height. The inertia will make the spacecraft rush onto the runway and finally go directly to the sky. We have tested this acceleration angle, and we'd better choose between 50 degrees and 55 degrees. In this way, the last charge of the spacecraft has reached a very high speed. "

"But in that case, you are the most, that is, flying knife low altitude orbit, and what about the position after that? With all due respect, that's not what this project does. If you do, you'd better prepare for vertical launch. I think it might be more suitable for you. Huayan's launch is directly to the sky through the electromagnetic acceleration scheme. This technology is not ejection, but an acceleration scheme of coil gun. This scheme will make the spacecraft fly out at a very terrible speed, and the initial speed of ejection is very high. Basically, it is not a problem to break away from the Taiyang system. After entering the low earth orbit, the engine will start, and then directly push the thrust to the more terrible speed out of the solar system, and use the forward trajectory scheme to drag the speed out of the solar system directly to the destination. So in terms of scheme, I think your scheme is unrealistic. "

"Oh, friend, I know what you think. We are just a preliminary idea now, so if you want to bid, you can design for us. "

"But what are you going to launch? Or what do you want us to do? "

"Yes, it's very important to launch the model and tonnage of the spacecraft, and now our companies don't have the ability to launch this kind of thing. Mr. Hoffman, do you have such ability? "

As the Royal representative finished, Hoffman waved his hand and said, "with respect to this plan, I can't do it. So far, we don't know the real layout of TIANTI base at all. Although our experts have talked about the situation there, we can see from the situation we have. That place is still very mysterious. There is no clue at all. At least in the next 15 years, it is impossible for any country to imitate it. There is a natural technical barrier to this thing, that is, the material barrier. I think they didn't use steel, or they used it very well. Just now, the base actually used a lot of super new materials, which are difficult to achieve with current metal materials. And when they accelerate, alternating current is still direct current. We're not sure. In this project, is it better to use DC or AC. We don't know that yet. In a word, the construction of TIANTI base can not be imitated. Since it can not be imitated, there is no way to surpass it. We are at least the same kind of products. What kind of speed is climbing? Are you eating something wrong? "

After Hoffman finished, there was a roar of laughter, but the most convincing thing was that the white elephant representatives were not shy or embarrassed at all.

At this time, the representative of CHONGYING said: "as far as we know, there is a new scheme for this runway, although the scheme of electromagnetic acceleration cannot be used. But at least magnetic levitation can be used. Building a super orbit and launching it directly at an oblique angle will have the same effect, but the total amount is not one order of magnitude at all. But the cost is far lower than that of Huayan. Our company is willing to undertake this project.

Xiang Qianjin looked at the representative. He nodded with a smile. Geng Li asked curiously, "what does he mean?"

"High speed rail." Xiang Qianjin said calmly.

"Ha? high-speed rail? This means that the runway is launched by high-speed rail. How many new lines have they built? Are you really going to build a train man Geng Li asked suspiciously.

Xiang Qianjin said with a smile: "in theory, this scheme is feasible. Increase the energy, make two orbits, and finally open. The chassis of the spacecraft can use a small roller. It's easy to shrink at that time. The electric propulsion part will be completed on the ground, and then build a pipeline in which the spacecraft will launch, Some of the thrust produced in this way is similar to that of a gun barrel, but I'm afraid that the weight can only be a few hundred kilograms. If you're lucky, you can fly to Mars

"Lying trough, CHONGYING is really scary. I can think of all these."

They are better than other countries in terms of tapping potential and doing details. Only they can win this project.

"You mean it's the same track as the ladder base?"

"Yes, but it needs to be covered with pipes. After all, it's a place with high salt and humidity, but it needs a nuclear power plant. If we are allowed to contract, this nuclear power plant should be built in package. After all, how to match it is the best for us to do it ourselves. Of course, the price can be easily negotiated, and we can provide super long repayment period, and there are also super low interest loan schemes, and the cooperation mode can be easily negotiated! "

Hearing the words from CHONGYING, the representative of white elephant was moved.

Geng Li asked curiously, "why do they do this?""Technology upgrading, that's smart. Our country can't build it, but it can build it for other countries. Maybe it will be free of charge in the future. Through the charging scheme, we can add a charging version of overseas launch site, and also play our own nuclear power brand. Why not?" When Xiang Qianjin said this, Geng Li shook his head and said, "it's impossible to prevent! Can't you people be clean? What a dirty trick? Are you not tired? "

Xiang Qianjin said with a smile: "ha ha, in this world, laziness can kill people."
