ps. Present today's update, by the way, pull a vote for the "Biquge www.biquge.info" 515 Fan Festival, everyone has 8 votes, and the vote will also give www.biquge.info coins to Biquge, kneel and beg everyone to support and appreciate!

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

"Support the preliminary general direction design, and the rest of the improvement work is up to you!" Lu Qiujian said, since he is the head of the space exploration program, it is time to come up with some results after such a long time, and the current one is a gift to the Chinese aerospace department.

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

"There are three ways to recover rockets, the first is the parachute, the second is the vertical landing design I give you now! The third is to press the wings on the rocket; after comprehensive consideration, our team feels that the second is more advanced than the parachute dropped studied by other researchers!" The gift that Lu Qiujian took out was recyclable rocket technology, which was based on his memories in the previous world, referring to the Falcon series developed by Elon Musk, the founder of the online payment system PayPal. and the new-shepard rocket developed by the blue-origin company of Amazon founder Jeff Bezos, who had an exchange with Lu Qiujian in Chang'an last year, based on the consideration of the current situation of rocket technology in China.

"Well, the parachute landing method can only complete the recovery of the first-stage rocket, and the vertex vertical landing gushing is more!" Senior Colonel Liu, who has been immersed in the aerospace field for many years, certainly understands the difference between the two technologies. Vertical landing is not only a way to recover rockets, it can also be used for fixed-point landings on alien planets. The completion of this technology is equivalent to clearing a major obstacle for Huaguo to land on the moon in the future.

The wider the range of applications, the difficulty of the technology will also increase geometrically. This requires more advanced engine technology, launch recovery and orbit technology, high-altitude orbit precision control technology, super heat-resistant material technology, and so on; more importantly, Huaguo has not yet figured out a clear direction, so it does not dare to rashly enter the actual verification. And the thing that Lu Qiujian is taking out now just solves these problems.

"Air rudder, engine vector injection, landing gear, descent engine" Colonel Liu looked at it and carefully counted the key technologies used in this design. These technologies are not much more than what they have now, and most of the design highlights are focused on technical tuning, combining the existing technology with a more advanced design, so that they can play a greater role.

Colonel Liu sat in front of the computer for several hours, pondering the information sent by Lu Qiujian; seeing that he did not respond for a long time, Lu Qiujian simply returned to the sofa and took out his tablet computer to do his own thing.

It wasn't until someone else came to Colonel Liu that he reluctantly looked up from the computer. Glancing at the Wen Jiàn handed over by the man, "You can find the deputy chief engineer for these things! I'm busy now, oh yes, don't go yet, go out and help me call a few deputy chief engineers, Zhang Gong, and Wang Gong over! Let them put down their work and come to me immediately, there are important things to discuss with them!"

The man went out to call someone for some reason, and Lu Qiujian looked at Colonel Liu with a smile, "Chief Engineer Liu, how is it, is this design reasonable? Can you complete it?" Lu Qiujian is still very sure of the thing he took out, after all, the Falcon 9 of -X company and the New-Shepard rocket developed by Blue-Origin have been successfully recovered. I have also further optimized the design of these two companies, and the certainty of success in the experiment is higher than that of them.

Senior Colonel Liu pondered for a long time before he said uncertainly, "According to my experience, the design you sent over has great hope of success in theory, but this is only a preliminary judgment, and I still need to study the specific conclusion carefully with other technical backbones of our center!"

"Then you study it slowly, I'll go to dinner first! I'll give you such a big gift, and now it's time to eat, and no one cares! I think I'll go to the Southwest Satellite Launch Center next time!" Lu Qiujian pretended to sigh, closed the tablet and prepared to get up!

Senior Colonel Liu is entangled now. It stands to reason that when it comes to meal time, he should go to eat with Lu Qiujian, but now the things in the computer make him really itchy and can't leave! So he had to get up and apologize. "The information you sent us is so useful! Now you give me the dragon liver and phoenix marrow ginseng fruit, and I can't taste it! I will immediately arrange for someone to take you to dinner, and when our research is over, I will definitely have a few drinks with you and make amends to you!"

Seeing that his attitude was sincere, Lu Qiujian also put away his jokes, "You can go to dinner first! I'll go to dinner first, and I'll come back after eating, you can ask me any questions you have." ”

"I'm really sorry, I'll arrange someone for you!" Colonel Liu picked up the phone on the table and commanded, and after a while, a young staff member came in and took Lu Qiujian to eat.

Then several core backbones of the base arrived at his office one after another, all of them were old partners, so these people didn't talk to him either, "I said Lao Liu! Why are you calling us over in such a hurry? The satellite will be launched the day after tomorrow, and I still have a lot of things on my hands now!"

"That's it, there was almost another problem with the second-stage rocket today, and I have to hurry back and stare at it in a while! Hurry up and say something, I'll leave early after that!" This one was even more anxious.

If it was any other time, Senior Colonel Liu would only be more anxious than them, but now that there is a plan for the recyclable rocket sent by Lu Qiujian, a mere satellite launch is nothing! He didn't hurry to speak, but called the guards at the launch center, "Now there is a very important meeting! You guys keep an eye on the door, and don't let anyone in! Oh, by the way, except for Professor Lu, if he comes, you will let him in immediately!"

"Huh, what did Professor Lu send?" someone guessed something, and said with a sigh of lips, "The algorithms he left us on his last visit are simply too useful! More than twice as efficient as the ones we used before! What is it this time?"

"The things sent this time are much more important than the last time!" Colonel Liu beckoned them to gather in front of his computer, "Come and have a look!"
