I ask you to build tractors, but you build rockets?

A hand pressed down on his shoulder.

"Aren't you happy to let you go? The organization chose you because they valued you. How could such a good thing have happened 10 years ago? Even the Alliance people couldn't do it. Besides, this is not for you to travel, but for us to find working direction!"

The person who spoke was Li Xi. He came to the Aviation Development Committee to ask for help. The Long March 5 was too difficult!

I won’t talk about the YF135 engine that will be used by the new Long March 5. To be precise, it should be called YF135K, which is a reusable version. The Sixth Academy said that it will be completed in 2018 at the earliest and 2019 at the latest, so that it can be completed before the first flight of the Long March 5 in 2020.

Due to the use of a new 6-meter-diameter arrow body, the technical difficulty of the long-five arrow body is still quite high.

7 YF135s, with a take-off thrust of 2,600 tons and a weight of 2,000 tons. Putting this data on a 6-meter-diameter rocket body means that the height of the rocket will be very high, and the structure must be strengthened again.

Not to mention the need to build a universal CBC, allowing the middle core stage to withstand a thrust of 2,600 tons on both sides. It is conceivable that at least the connecting mechanism needs to be newly developed, and it must be quite powerful.

There is another key question, how to recover the Long March 5?

To be on the safe side, of course, he would continue to recycle the supporting legs, but Academician She came to him a few days ago and said that the feasibility of recycling the supporting legs could be passed, but future projects must be considered.

The future project is of course the future reusable super giant rocket Long March 9.

It has a take-off thrust of 10,000 tons, which can hit all rockets in the world, and a low-Earth orbit carrying capacity of 300 tons, which can hit an entire landing spacecraft!

The recovery method of Long March 9 cannot be recovered vertically with support legs. It is too tall and complicated. The ideal way is to find a way to support the grille rudder like Xinyuan 2, which avoids the height problem and has greater potential.

But the recycling of the grille rudder... How should I put it? When He Zhuang heard this, he had a "I would rather die" expression on his face, and claimed that the Eighth Institute was too busy and asked him to come back after landing on the moon...

I didn’t expect that after a while, big news would come out?

When the noise started below, the boss promptly silenced everyone and said gently:

"This space training actually has a little bit of reward awareness, but the talents selected this time have made outstanding achievements in their respective fields, and their contributions to the country are fully worthy of such rewards;

At the same time, they will also be entrusted with important responsibilities after returning and work harder to lead China's aerospace industry forward! My superiors have communicated with me many times, meaning that comrades should not bear any psychological burden. This is originally an inevitable process as we move towards space! "

After the boss finished speaking, he sat down and motioned for everyone to express their opinions.

Lin Ju raised his hand with a swoosh:

"Well, I would like to ask, since the proposal was first announced within the Aviation Development Committee, does it mean that the manned flight mission is also decided by the Aviation Development Committee?

If the H1 space shuttle is used, Xinyuan still offers a final quotation of 350 million yuan for the space shuttle and the combination. If the seat is shared, the price will fluctuate. The single-seat ticket price of the Steadfast with 10 people is 38.88 million yuan. Yuan, not including training fees, this price should be very favorable. "

"..."

None of the committee members expected Lin Ju to react so quickly and immediately start promoting his own space shuttle.

But for now, the space agency really lacks cheap and reusable manned means.

At present, the space agency's planning method is only a new generation of manned spacecraft to match the new Long March 7 method.

Thanks to the increased funds from the Sixth Institute to open the YF100K mass production line and the large-scale expansion of the Jingu rocket manufacturing base, the cost of the Long March 7 has actually dropped from 680 million yuan for six YF100Ks to 390 million yuan for the 10-engine version.

The mass production line built for a large number of launch missions is very scary in terms of cost reduction. This is a rocket with a capacity of 20 tons in low-Earth orbit. A mere 390 million yuan is really cheap.

The reusability of one and a half levels (booster counts as half level) can also reduce the cost of Long March 7 by about 67%. One shot of Long March 7 can be reused 15 times, which can reduce the cost of a single shot to 155 million yuan.

The new generation manned spacecraft test ship costs 1 billion yuan to build. Each time it is reused, a new service module needs to be mounted. After 15 launches, the average cost is only about 113 million yuan.

In the end, each launch mission cost about 268 million yuan, and after seven people were seated, each person spent about 38.28 million yuan.

It's cheap enough. It's almost ten times cheaper than the Shenzhou spacecraft which cost more than 400 million. It was unthinkable in the past.

Renting Unity to launch six astronauts costs an average of 58.3 million per launch, which reduces the cost by about 34%.

Even if Xinyuan Aerospace launches the large-capacity Steadfast, the new-generation manned spacecraft test vessel can still be expanded!

If we follow the example of the Steadfast, which completely abandons the cargo hold and uses all crews, the new-generation manned spacecraft can seat 11 people, and the unit price is 24.4 million, which is cheaper than Xinyuan!

And these are not long-term ideas, but are planned to be realized around 2017.

The superiors had already understood this plan in detail when they were discussing how to send experts to space. After confirming that they could send people to space cheaply next year using their own rockets and spacecraft, they decided to issue a proposal.

The boss has received a clear order. This year, he can use outsourcing to carry out training tasks, but next year he must use a spaceship.

The budget of 400 million was also formulated with the 390 million stuck in this plan, and the superiors asked them to find ways to reduce the cost further.

After all, Xinyuan Company can offer a price of 350 million yuan and still make a lot of profit, which shows that the cost of rockets can still be kept low!

Lin Ju also knew about this plan, but he didn't know the progress, so he wanted to know who would undertake this year's launch mission.

Although it is unlikely that this project will be handed over to Xinyuan, what if.

From this proposal, Lin Ju noticed a major change in thinking at the top level by comparing it with the information from his previous life, and he attached great importance to space investment.

Spending 400 million a year like this to send aerospace experts to space was absolutely impossible in the previous life. It can only be said that the environment has caused huge changes.

And this has been foreshadowed for a long time, as can be seen from the restart of the Dawn Plan.

Of course, Lin Ju welcomed this with both hands. He was forced by the system to roll into space desperately. Lin Ju would be much happier if he could get everyone to roll into space together.

Of course, Lin Jujuan's happiness was not necessarily the case for others.

When these experts heard the quotation of 38.88 million, their hearts twitched.

Highly reusable and with many seats, can you really do whatever you want? It's actually possible to spread the average price to this point.

Fortunately, the potential of H1 has almost reached its limit. Xinyuan No. 5B has a maximum transport capacity of just 21 tons. Otherwise, would the price be lower if a few more seats were added?

The boss coughed: "As for this year's launch mission, superiors have instructed us to bid internally within the Aviation Development Commission. Anyone who has the ability to undertake the mission and does not exceed the budget can apply. However, the training of the five experts will be carried out in the HD area. The launch It’s enough to squeeze in two months of training time beforehand, and it doesn’t matter if you squeeze in a few days every half month.”

Lin Ju sat back and the Aviation Development Commission bid. Isn't it almost obvious that H1 will take the order?

More if you want more
