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

"The RX01 data bus can simultaneously sense sensors all over the rocket and process all external factors in parallel. This is the key to our success. C-class rocket recovery technology alone cannot achieve this effect."

After a short celebration, a dedicated team has gone to the landing site to recover Xinyuan-1B. They will drag the rocket back to the factory for careful inspection to determine its condition.

The purpose of recycling is to reload and shoot out. It is useless to just get back an empty shell.

At the same time, Lin Ju held a summary meeting with the engineers mainly involved in recycling, including not only system engineers but also many senior researchers who had been poached.

Guo Shen was the leader of the team that took the lead in figuring out the control system, so he first talked about the important factors in rocket recovery.

Everyone else agreed with this and clapped.

"Mr. Guo, is the RX01 specification really created by us at Xinyuan?"

A later senior software engineer couldn't help but ask, because the data indicators of RX01 were too amazing, and it was very dazzling in this recycling. It didn't look like it could be developed by a small company.

The 1553B data bus specification, currently the most widely used in the world, was created by Aramco in the 1960s and is still an advanced representative. China has learned and used it in its own aerospace field.

Guo Shen: “Of course we created it independently, but its origins can be traced back to an abandoned project of the Aramco Space Agency in the 1990s. At that time, they hoped to create a new specification for a spacecraft to land on Mars and put forward an idea.

Androv provided the alliance with a lot of launch data from the last century, as well as some of ESA’s experience. Finally, we jointly completed the design of RX01. Now I can say that this is the most advanced bus protocol in the world. "

The source of technology must have a provenance. It just so happened that the system engineers came from three places: Lucia, Ame, and Europe. It was easy to pass the blame.

From the control system to the engine to the recovery process, everyone spent an hour making a brief summary and confirmed that although there were still many areas worth improving, the main processes were correct and there were no major mistakes.

As for the sudden cross wind when landing, the solution is simple and crude. Set up as many observation stations as possible and make the landing site as open as possible and free of terrain undulations.

The most ideal location is offshore, which can avoid rocket explosions caused by failure and affect the surrounding area, and can also use water vapor to transfer heat. However, the difficulty of recovery at sea will increase by another level.

By the end of the meeting, the inspection team’s preliminary assessment report was also sent over.

Through flaw detection on the engine, rocket body and other parts, the inspection team basically determined that there were no defects or damage. It only needs to be repainted and fueled, and it can be restored to launch status within a week.

Lin Ju didn't read the details and turned directly to the end, where a red stamp said "passed."

This means that as long as this rocket is launched again, the average cost of two launches will be reduced by 30%. If it is reused 5 times, the average cost will be reduced by 45%. If it is reused 10 times, the average cost will be only 50%. .

In other words, after the Xinyuan-1 family achieves first-level recovery, as long as it can be successfully recovered four times, the cost of each rocket can be kept at 10 million. The low-Earth orbit transport capacity of the recyclable version of the rocket is about 1.3 tons, on average The LEO launch cost is about 7,700 yuan per kilogram, which is just over 1,000 U.S. dollars based on the U.S. dollar exchange rate at this time.

The main SSO rail transport capacity has shrunk to 680 kilograms, and the cost of one kilogram is only 14,000 yuan, equivalent to 2,000 US dollars.

This is still because the Xinyuan-1 rocket is small, and the cost of the first stage accounts for only 60%. The larger the rocket, the heavier the first stage, the higher the cost ratio, and the higher the efficiency of recycling. If the Xinyuan-3 in the design is also recycled, 5 The average launch cost will be reduced by 70%.

After doing a rough calculation on the paper, Lin Ju swallowed hard.

If all the rockets launched next can be recovered, then the cost will be significantly reduced?

Of course, there are also people who want to work with their bosses.

After walking out of the conference room, Hu Bo, the vice president and temporary assistant who was following Lin Ju, said seemingly unintentionally:

"Next month's new Grade 1-C will also have a diameter of 3.5 meters. If we use this recycled Grade 1 to install it, we can save at least 9 million. The profit on this order is less than 8 million."

Lin Ju shuddered and then seriously criticized his unhealthy thoughts.

"We have agreed with the customer that it is a new rocket. How can we modify it? Besides, this is only recycled once. What if something goes wrong next time?"

Although he was indeed very moved, this kind of thing was unethical, and it would not be good to tell others about the first commercial order by using a second-hand rocket.

"Then, let me ask Commander Androv if he can change the first level of Xinyuan No. 1-C to be recyclable? It wouldn't be a loss."

"This...you go ask Androv?"

"yes!"

…

The recovery of Xinyuan-1B rocket made history, but how big is the impact? It’s so big that the private space industry will soon be turned upside down!

More venture capital investors came to Lin Ju, and this time their attitude was extremely firm, even more fierce than last time.

Because reusable rockets represent one thing: private spaceflight, where you can really make money!

Unfortunately, although aerospace is high-tech, it has never been completely profitable. It relies on derivative technologies to create profits indirectly, and high returns cannot be obtained directly.

But if the reusable rocket is successful, as the launch unit price is cut in half, a large number of customers will be tapped, the aerospace market will be greatly expanded, and sustained profits can really be achieved.

Regardless of how Lin Ju deals with investors, the impact has already spread to Aramco anyway.

Lao Ma's empty fork continues to be favored by people in the stock market, and the stock price has already shown a rising trend. After all, Falcon 9 and Xinyuan 1B follow the same route. How long will it take to succeed?

Several other Aramco private aerospace companies rushed to the PPT overnight, saying that they also have rocket recovery and development plans. Although they look different, the original route is still vertical recovery.

Investors still do this. In the past, if you said you wanted to recycle rockets, they would scold you and think you were setting off fireworks.

Nowadays, as long as you take a PPT and show it to investors, you can give it a few million dollars to test the waters. Just like the rise of the Internet era, as long as you have creativity, you will get large investments.

The recycling of Lin Ju directly caused the private space market, which was still in its infancy, to gradually become more lively.

Domestic private aerospace companies, which were originally set up in a few years, are now preparing materials to register trademarks, and are also preparing to change their PPTs to find investors.

At the home country's space agency, the originally calm and continuous environment began to tumble like a piece of red-hot iron being thrown at it.

Because the space agency is also in a critical period at this time:

The development of large rockets represented by Long March 5 is about to be completed. The three brothers Long March 6, Long March 7 and Long March 8 based on YF100 are also on the verge of production. The next few years will greatly expand the aerospace family pedigree.

Because of these new rockets, the lunar exploration and Mars exploration projects have been launched, a new generation of manned spacecraft has entered testing, and a new generation of large space stations are also being planned.

Further back, there are the super-heavy rocket Long March 9 and the new generation manned rocket currently only code-named 921, based on the two, manned exploration of the moon and Mars.

In the field of cheap and reproducible access to space, the important task rests on the "Tengyun" project that has not yet been fully established but has been basically determined.
