ps. Here’s today’s update. By the way, I’m going to vote for the 515 Fan Festival. Everyone has 8 votes, and you’ll get coins for voting. I beg you all for your support and appreciation!

Colonel Liu excitedly took the USB flash drive and immediately inserted it into his laptop, "This is what you said last time, and the result is coming so soon?"

"I support the preliminary general direction design, and you have to do the rest of the improvement work!" Lu Qiujian said. Since he is the head of the space exploration program, he should produce some results after such a long time.

Here we are, and what we see in front of us is a gift to China’s aerospace department.

"Oh? Are you using the second method? It's a little different from what we are mainly studying now!" Colonel Liu opened the file and quickly saw the content of Lu Qiujian's gift.

"There are three ways to recycle rockets. The first is the parachute type. The second is the vertical landing design I am giving you now! The third is to put wings on the rocket. After comprehensive consideration, our team

I think the second type is more advanced than the parachute researched by other researchers!" The gift Lu Qiujian gave out was recyclable rocket technology. This achievement was based on his research in the previous world.

The memories refer to the Falcon series developed by the spae-x company of the online payment system Paypal founder Elon Musk, and the exposure of Amazon founder Jeff Bezos who communicated with Lu Qiujian in Chang'an last year.

The NE-PARD rocket developed by e-Origin Company is an optimization plan based on consideration of the current situation of China's rocket technology.

"Well, the parachute method can only complete the recovery of the first-stage rocket, but the vertical landing method has much more potential!" Colonel Liu has been immersed in the aerospace field for many years, and of course he understands the difference between the two technologies. The vertical landing method

This method can not only recycle rockets, but can also be used for fixed-point landings on alien planets. The completion of this technology is equivalent to clearing a major obstacle for China to land on the moon in the future.

The scope of application is wider, and the technical difficulty will also increase geometrically, which requires more advanced engine technology, launch recovery and orbit entry technology, high-altitude orbit precise control technology, super heat-resistant material technology, etc.; more importantly

It's because Hua has not figured out a clear direction yet, so it dares not rush into experimental verification. But what Lu Qiujian has come up with now just solves these problems.

"Air rudder, engine vector injection, landing gear, descent stage engine" Colonel Liu carefully counted the key technologies used in this design while looking at them. These technologies are not much beyond the technology they currently have.

The highlights of most designs focus on technical optimization. Combining existing technological levels with a more advanced design allows them to play a greater role.

Colonel Liu sat in front of the computer for several hours, carefully considering the information sent by Lu Qiujian. Seeing that he had not responded for a long time, Lu Qiujian simply returned to the sofa and took out his tablet computer to start his own work.

Things come up.

It wasn't until someone else came to see Colonel Liu that he reluctantly raised his head from the computer and glanced at the document handed over by the person. "You can ask the deputy chief engineer for these matters! I'm busy now, right?"

Come on, don’t leave yet, go out and help me call the deputy chief engineers, Engineer Zhang, and Engineer Wang over! Ask them to put down everything they are doing and come to me immediately. We have important matters to discuss with them!"

The man went out to call for help without knowing why. Lu Qiujian looked at Colonel Liu with a smile, "General Engineer Liu, how are you? Is this design reasonable? Can you complete it?" In his heart, Lu Qiujian was right.

I'm pretty confident about what I took out. After all, it's a spa.

The Falcon 9 of the e-x company and the NE-Pard rocket developed by the blu-e-Origin company have both been successfully recovered. I have also further optimized the designs of these two companies. I am sure that the test will be successful.

Only higher than them.

Colonel Liu pondered for a long time before saying uncertainly, "According to my experience, the design you sent has a great chance of success in theory, but this is only a preliminary judgment. I still need to discuss the specific conclusions with our center's

Other technical backbones will study it carefully!"

"Then you study slowly, I'm going to eat first! I gave you such a big gift, and now it's dinner time, no one is paying attention! Hey, I think I'd better go to the Southwest Satellite Launch Center next time

Now!" Lu Qiujian pretended to sigh, closed the tablet and prepared to get up!

Colonel Liu was confused now. Logically speaking, when it was time to eat, he should go to eat with Lu Qiujian, but now the things on the computer made him really itchy and couldn't leave! So he had to stand up and apologize, "You

This was brought to us

This information is really useful! Even if you give me dragon liver, phoenix marrow and ginseng fruit, I can’t taste it! I will arrange for someone to take you to dinner right now. When our research is over, I will have a few drinks with you.

, I apologize to you!”

Seeing his sincere attitude, Lu Qiujian also stopped joking and said, "You go about your business first! I'm going to eat first. I'll be back after dinner. If you have any questions, you can ask me."

"I'm really sorry, I'll arrange someone for you right now!" Colonel Liu picked up the phone on the table and gave some instructions. After a while, a young staff member came in and took Lu Qiujian to have a meal.

Then several core members of the base arrived in his office one after another. They were all old partners, so these people talked to him without being surprised, "I mean, Lao Liu! Why did you call us here in such a hurry?"

The satellite will be launched the day after tomorrow, and I still have a lot to do at hand!"

"That's right, something almost went wrong with the second-stage rocket today. I have to go back and keep an eye on it soon! If you have anything to say, hurry up and I'll leave early!" This person was even more anxious.

If it were any other time, Colonel Liu would only be more anxious than them, but now with the recyclable rocket plan sent by Lu Qiujian, a mere satellite launch is nothing! He did not speak in a hurry, but spoke

The guard at the launch center was called on the phone, "We have a very important meeting now! You two, guard the door and don't let anyone in! Oh, by the way, except for Professor Lu. If he comes over, let him in immediately!"

"Huh? What good stuff did Professor Lu send?" Someone guessed something and tsked his lips and said, "The algorithms he left us when he came to visit last time are so useful! They are much better than the ones we used before.

That kind of efficiency is more than twice as high! What is it this time?"

"The things I sent this time are much more important than what I gave last time!" Colonel Liu called them to gather around his computer, "Come and take a look!"

[515 is coming soon, and I hope to continue to hit the 515 red envelope list. On May 15th, the red envelope rain will be able to reward readers and promote the works. It is also love, and I will definitely update it!] (To be continued.)
Chapter completed!
