Chapter 443

Xiang Qianjin said with a smile: "yes, it's equivalent to playing a trajectory in the solar system. We use the gravity of the solar system. We need to know that gravity is omni-directional. We first fly out by force, and then find a point to enter the orbit. When we cut into the orbit intersecting with Saturn, we will be pulled back by gravity, and then go around the orbit of revolution to intersect with Saturn's orbit, Yes, as long as everyone is on the same side of the track at the same time. In this way, the scope of window period selection is much larger. You don't need to accelerate one planet at a time

White hawk expert nodded with approval. He took the information and said, "if you realize all the above things, then I think this plan is feasible. But this trajectory is different from the trajectory we know. It's not a parabola. First of all, our breakthrough flight is an arc towards the sun in the ascending phase. This vertical trajectory is relative to the earth's ecliptic plane. We use a velocity to fly vertically. But it still flies towards the central sun, so in the final acceleration stage, we have to change the direction to enter another orbit around the sun. The ascending orbit we care about is a C-shaped orbit, facing the sun. Then we change the flight direction of the spacecraft like drawing the moon, and then we go into a orbit perpendicular to the ecliptic, In the descent phase, you just need to adjust your flight direction. This way, you can charge and fly at the same time, and the time should be in time! "

"In other words, the fastest speed will be used to send the spacecraft to the orbit perpendicular to Saturn, and then start to revolve? In this way, we actually use the shortest way to find the orbit of Mars, and then maneuver to change the direction of the orbit until we find an orbit that can be caught by Saturn's gravity. In this way, we can greatly reduce the effect of Jupiter's gravity

"That's what it means! We're not going around. We're going to do a crazy parabola more directly. I think if we can do it, we should call it a forward trajectory. If we can do it

Xiang Qianjin thought about it, and then said, "another name, but this plan can be considered. I still trust our equipment. After all, what we lack is time!"

"If this orbit is OK, then the rest of the plans can fly along this orbit. In the transportation stage, it's better to send it at a speed of 30km / s. The higher the speed of the transport plane, the faster the final speed will be!" The experts of white hawk really came here with the intention of cooperation this time. Mona raised her hand and said, "Mr. Xiang, can the ejection trajectory you built in Tibetan areas deliver this speed to this speed? You didn't build that thing to replace transport, did you? "

"It's very difficult for transport planes to put more than 200 tons of things into orbit at such a high speed, but spaceships can. But this will test our pilots. The speed is very fast. At the moment of breaking through the flag, we need to break through the wonderful speed of 31km. In this way, we will have enough assurance to maximize the thrust, and then continue to fly upward. And then start flying directly. "

Mona whispered, "so what's the biggest difference between the two?"

"Load, that is to directly send 50 tons of load up, the total weight of our warhead is more than 25 tons, that is to say, this thing will fly straight to the asteroid with very fast speed, and then hit directly! White hawk's plan is to destroy in the asteroid belt, such a part of the debris may impact in the asteroid belt and change its orbit, but the hidden danger is that it is easy to blow other asteroids to the earth. Our interception is divided into two stages. The first stage is called the battle of Saturn, which is part of our plan for the south gate. This space shuttle will send robots to asteroids and intercept them directly. "

"In that case, our Cassini Saturn probe orbiting Jupiter will be able to give you orbital data. Cassini is now orbiting Jupiter, and it can measure the orbit and gravity of Jupiter. Just go beyond the gravity. Then there is the data from Cassini and our calculation of Saturn's orbit. It's easy to determine an orbit that can break away from Jupiter's gravity and fly directly towards Saturn. "

Xiang Qian nodded and said, "please! The launch phase can't be changed. We need to seize the time. It's just to find a direction. We can calculate the orbit change data before accelerating to the inflection point, so that we can fly directly into Saturn. "

"Well, it may take a lot of energy to fly at a speed of 51 meters per second, but if your spacecraft can do it, it's really not difficult."

Xiang Qianjin said with a smile: "this is still guaranteed. The maximum thrust of the space shuttle is more than 12000dan, that is 120000n, eight. I think it should be OK."

"Infinite close to a million cattle thrust, in the nuclear and graphene batteries and graphene material blessing, this is the pinnacle of human work. I didn't expect that a seemingly insignificant plan is the ultimate plan of mankind. If this plan is successful, then we have an idea, that is to open up our cooperation with Huaxia. Our cooperation should not end after this operation. We should be faced with the problem of benefiting all mankind. ""I think it still depends on the efforts of both sides. In our Chinese words, it's quite like falling in love. You can't shave your head and pick a hot one. We don't want to dominate the world, but we don't want to give away our achievements. I don't believe that science and technology have no national boundaries. The birth of science and technology in any country will give it a deep brand, so we can only say that we will not use it to dominate and attack other countries. As always, we will live in peace with any country in the world and make good friends. But for technology sharing, I'm sorry I can't. I am also a businessman, and I have spent a lot of money. The R & D funds we burned last year have exceeded the R & D investment of Huaxia. In the world, the total amount of R & D investment of Huayan ranks the second, and the profit and R & D capital investment rank the first in the world. Our total R & D capital is 200% of our income. We have only cleared our debts this year. Now, in this Nantianmen plan, our debt is as high as 60% of our total output value. Therefore, our task of making money is urgent. Let's make good money for two years. But I want you to promise that the door of cooperation will never be closed. Huayan is willing to cooperate with any country in the world. As long as you are sincere, I will be frank with you. The R & D of Huayan is inseparable from the support of the world. As for our space shuttle, CHONGYING's suppliers account for 18%. Basically, the key components of high-end metal materials and composite materials are provided by CHONGYING. We would like to thank you for that. "

Speaking of this, white eagle experts are very curious, Mona asked: "about the material problem, white eagle's company also has a lot! Moreover, compared with CHONGYING, aerospace materials are not inferior to them. "

"There are two problems. First, we can't buy your materials. Second, we are used to using CHONGYING's materials. We can't say that the materials of Baiying are not good, but your control is too strict, we can't get them easily, and your supply is not stable. There is no way to solve this problem. There is not much interference between us and CHONGYING. There is no extremely special situation. There is absolutely no interruption of supply. Therefore, in this regard, we will choose some relatively stable countries for cooperation. Of course, this is not to say that we are unwilling to cooperate with Baiying. We are looking forward to cooperation. In the high-end industry alliance proposed by Huayan, we have very close cooperation with Baiying. But I can only say that there are certain restrictions on our cooperation, and we can not work together. Therefore, before completely breaking down barriers and barriers, we can only try to cooperate, not fully open up. What I guarantee is that the door of technical cooperation will never be closed. "

When Xiang Qianjin said that the White Eagle experts were convinced, Mona said in a deep voice: "I can understand that if I were you, I would not choose to cooperate easily with those arrogant ghosts. But you are really a very kind person. Thank you for not closing the door to dialogue. As long as the communication is still going on, as long as we can communicate, I believe we will move towards a better situation. "

Xiang Qianjin said with a smile: "yes, I'm very optimistic about our cooperation. I don't have any reservations about this. It's like we're now opening up good opportunities for cooperation? If there is no problem, we will officially announce it now, if you like. We will form an interim global technical cooperation committee, and I will formally invite you to participate in the whole process of saving mankind! "

"I'll take part!" The experts from the Northern League raised their hands first, and then the experts from CHONGYING said with a smile, "we are very happy to join."

"I will!"

"I love this country, and it doesn't matter if I'm there as long as I can work for all mankind."

All the experts are expressing their opinions. In the expert group of white eagle, Mona stood up and said, "I'm willing to join. I don't care what their attitude is, but I'm willing to join on behalf of myself!"

Xiang Qianjin smiles. He looks at Mona and says, "I don't have any opinions. Welcome! Miss Mona

"We are also willing to join in the cooperation. During our stay in China, we will try our best to help you, but are you willing to let us into your

Chou chuckled and walked into his hand. As a result, the microphone said, "you are allowed to enter the launch center! We have received instructions from our superiors. This is a matter for all mankind. Huaxia can't support it. Therefore, on behalf of our country, we hope that people of insight from all over the world can come and save the world with us. We Huaxia are not the Savior, we are just a member of the global village. We sincerely welcome every expert from all over the world to join us. As long as you are willing to work hard for mankind, we will welcome you. We are in urgent need of all kinds of astronomy talents. We have no experience in long-range interstellar navigation. We have never been to Jupiter. We sincerely welcome experts with this ability and talent to join us in the future. Let's fight the havoc together

Applause, thunderous applause in the audience, experts spontaneously stood up to applaud for the project, but also for China, until today, they saw the hope. An unexpected hope
