Chapter 329: Landing
Compared to the land launch site, the sea mobile launch platform feels a little awkward for everyone else.
However, they have no problem with building more offshore recycling platforms, which is not a large investment and the cycle is relatively short.
In fact, Seryov himself did not have much confidence in this project, mainly because the meteorological department provided typhoons No. 1 to 22 to the Aviation Development Committee was really urgent, and he had to come up with a solution that was not a solution.
The idea of borrowing the Mukara launch site was actually not very mature, and although it was indeed feasible, there was only one launch station, and the conditions were really limited and of little significance.
But the problem of affecting the launch could not but be faced, and seven or eight people discussed and discussed, and finally Ke Yun proposed a different solution.
"This year, we mainly launched the No. 3 rocket and the No. 2A CBC rocket, and the problem is that we can only launch from the large launch site in Qiongzhou, right?"
The rest nodded subconsciously.
"But guys, why are we launching in a low-dimensional field?"
"To increase the capacity of the rocket, of course."
Ke Yun: "However, the maximum take-off weight of H2M and H2 is 135 tons, and the maximum carrying capacity of Xinyuan-2A is also 135 tons, but what is their launch weight for our main launch mission this year?" ”
Seryov was stunned for a moment, and then reacted.
"100 tons, no more than 110 tons."
Ke Yun nodded: "What about the No. 3 rocket, its low-earth orbit capacity is 270 tons, and the launch of three spoke compartments plus brackets is only a little over 100 tons, I remember that our last launch was launched with reduced fuel filling."
So we can completely widen the inland launch site, which is at least much cheaper than the sea and overseas launch sites. ”
Ye Changsi: "Inland launch site...... Se Chang, no, Jiuquan, it's very wide, the loss of capacity is about 3% to 5%, we can accept it, and there is an airport there, I was ...... It will definitely be able to take off and land the An-1250.
Well, let me go and see what it's like now, I'm pretty familiar with it. ”
Seryov also had to nod, his inertia of thinking and the Union's innate desire for low latitudes made him make an empirical mistake, after all, Baikonur's 46-degree "low latitude" really cast a deep shadow on the Soyuz spaceflight.
Lin Ju participated in the whole process from the perspective of a bystander, and finally asked:
"Then we will focus on funding, technology licensing is useless to us, how much is appropriate?"
Guo Shen thought for a while and gave a figure: "The value of such an important technology is immeasurable, and what it brings to the country is bargaining power and the confidence of isolation, and I think we must be compensated at least 10 billion yuan." ”
Ye Changsi: "Ten billion?!" ”
Guo Shen: "What we are given is RMB, which can be printed at any time, this is just cash flow, I think we also need a nearby infrastructure fund, which can add up to 20 billion." ”
Lin Ju, who had already seen the world and high-level chatters, was not too surprised by this number at this time, and nodded casually:
"If we hand over the money to develop aerospace technology, we can directly provide orders to 10 high-tech enterprises, and we don't have to pay it off all at once, just give it in the form of policy support in several years."
Ye Changsi: ......
He knows that although Xinyuan is a top super enterprise in the country, it still enjoys various local preferential policies every year.
Lin Ju: "One more thing, guys, if we have more money, can we try to develop a supersonic business jet?" It is not very good to always fly training planes on military routes. ”
Seryov: "I'm afraid Anderov has more say in this matter. ”
Anderov: "How many times the speed of sound?" Ten times more? Do you want us to directly use the body of the snowbird? It takes 15 minutes to fly from here. ”
“……”
Seryov: "If you can convince the Civil Aviation Administration to issue an airworthiness certificate, then I think we should be fine, and besides, I'd rather take a rocket than that." ”
……
"Isis-1 is NACA's first nuclear-powered rover to land on the Moon, and the single largest, heaviest, and most capable lunar rover on the Moon, which will provide more visibility into the Moon's resources.
Jim Free, head of the Isis program, said: "This is the most powerful rover we've ever built, and it's also a lunar rover that condenses hope, carrying 3 grams of lunar soil brought back by the Apollo program, and now we're going to send them back to the moon. ”
Isis 1 was in a hurry, and did not have time to collect 100,000 names from all over the world, but pulled out three grams of lunar soil from the Moon Landing Museum, symbolizing a return to the moon.
On March 5, Isis 1 became the second Aramco spacecraft to reach lunar orbit in four months.
At this time, it is gradually lowering its orbit and preparing to land in the Aitken Basin in Antarctica, as well as around the Qom impact crater.
The landing was still broadcast live around the world, but not very much interest.
Now, eyes on the moon are more focused on Dawn 2.
Since entering the lunar orbit on February 14, the world has been waiting for the "full moon" to carry out an unmanned landing mission, but Dawn-2 does not seem to be in a hurry to land, and has been circling the lunar orbit.
Dawning-2 was originally planned to carry out an unmanned landing mission on February 20, and then load the lunar soil ascent docking spacecraft on February 24 to transfer samples and fly back to Earth.
However, there was a little accident the day before the landing, and eight Explorer II robots, including Yutu-3, inspected the expected landing site in advance, and finally found that there was something wrong.
The shallow ground of the Qom crater is ice, which causes the lunar soil covering their surface to be quite loose but loose, and the 8-ton thrust reverser engine of the "Full Moon" only needs to stay for 0.5 seconds to blow out a large crater, which is very likely to cause the landing leg support to be unbalanced and skewed.
The Yutu-3 lander had suffered similar losses before, but its engine thrust was small and lightweight, and the "Full Moon" was a big guy.
It took half a month for the Aviation Development Commission to continue to find a suitable landing site, and finally settled on an open space outside the edge of the impact crater, the difference between the inside and outside is not large, and the lunar soil is very solid, and the landing leg will sink into about 5 to 10 cm, and the card is very stable.
Fortunately, the unmanned landing test was done in advance, otherwise it would be really tricky to encounter this trouble when the official moon landing.
The timing of the landing was also very coincidental, and it was only 10 hours away from Isis I......
Needless to say, which is more interesting, the 1-ton lunar rover or the 23-ton lander, so NACA was fiercely robbed of a wave of traffic.
In particular, both landers are preparing to land near the Qom impact crater, and if the time is not staggered, I am afraid that there is still a risk of a collision in the air?
At 18 o'clock in the evening of March 7, Beijing time, near the No. 1 landing site of Qom Impact Crater, the two Yutu-3 and the lander with them jointly sent radio signals to provide accurate positioning and navigation services for the "Full Moon", and the "Full Moon" and the command module of the Shuguang-2 spacecraft were disconnected and began to slowly descend in altitude.
