Military Technology

"Then buy a new one, and you can't spend any more money anyway." Zhang Jun said cheerfully, for him or for everyone, the new one is better than the second-hand one.

During their chat, the team also gradually moved to its destination, a rocket launch test site at the end of this desert road.

This is also Wu Hao ’s recently completed rocket launch test site in the Northwest Desert. The entire rocket launch test site covers an area of ​​10,000 acres. However, only a small part of the effective land is used, and the other parts are vacant land. Drought-resistant trees and vegetation will be planted in the future.

And in order to facilitate the transportation of rockets and equipment, they also built a desert asphalt highway to connect provincial roads and highways, a rocket launching test field that has extended into the desert hinterland.

Of course, this rocket launch test site is not built casually. Not only does it require exploration in advance, but it also needs to apply for reporting, it also needs to coordinate local and even multiple departments, which is very cumbersome. Fortunately, the aerospace authorities have already formulated a complete set of regulations and standards for the private aerospace industry, and they have even stipulated the location of rocket experiments, so they did not make much effort.

It is said that it covers an area of ​​10,000 acres, but when they arrive, they find that the building of the entire base is actually some mobile board houses and containers.

Because the time is too short, the infrastructure of the entire base has not yet had time to start construction. Therefore, currently only some mobile board rooms and some offices converted by containers are used for the launching experiments at this stage.

"General Manager Wu, General Manager Zhang, welcome and welcome!" Yu Chengwu led a crowd to welcome them with a warm handshake.

"It's too desolate, too."

Zhang Jun looked at the surrounding environment with a sun hat and sunglasses, and couldn't help but exclaim: "Did you just stay in this environment for more than half a month, it's really not easy."

"Oh, nothing, we are used to it." Yu Chengwu grinned at Zhang Jun with his white teeth grinning. It may be that the sun has been in the sun for a long time, so this handsome guy from the original innocence is now tanned and tanned. I do n’t know where he moved the bricks and labored.

"How can I see you alone, Xiangming?" Wu Hao asked, looking around.

Hehe, Yu Chengwu signaled to them about a kilometer away and laughed at them: "At the launch site, today the temperature is a bit high, he has been staring at the scene to ensure that the rocket is foolproof, and the final inspection is currently underway."

"When will it launch?" Zhang Jun could not help but ask.

"The launch window given to us by the competent authorities is from 3:30 to 8 in the afternoon, so we have enough time to prepare. We initially plan to launch the first experimental rocket at 4.50 in the afternoon and the second at 6 o'clock. Experimental rockets, one hour and ten minutes apart.

In this way, we have ample preparation time among us. However, this time is not accurate, and gusts are easy to occur in the desert. If the wind speed is too high, the launch time may be delayed. "

Wu Hao nodded and nodded. Now that they're all set, he won't say anything anymore, everything will go according to their plan.

"I'm here to bring you some consolation goods, and you arrange for someone to give you a point. It's been a hard time for everyone, and I will go back and invite everyone to eat a big meal." Wu Hao laughed at everyone who was hugging him.

"Hahaha, thank you, Mr. Wu, long live Mr. Wu!" A group of scientific researchers heard the words, and leaped with joy and laughter.

Everyone is young, so they are very serious in doing this kind of career. Although it was a bit hard, everyone was happy. And Wu Hao is not bad to them either. Not only does he have a generous salary, but more importantly, Wu Hao's appetite for them. Everyone is convinced and agrees with this big boss.

"Okay, don't stand in the sun, don't even think you're dark, find a place to avoid and take advantage of the cold. By the way, there are some sunscreen and sunscreen in the condom I brought this time. When you look back, remember to use it, especially girls.

Originally, all of the pretty and handsome girls and boys had come to the desert for a few days. If you do n’t protect it well, go back to your boyfriend and girlfriend and do n’t want you anymore, do n’t rely on me then. "

Hahahaha ...

After joking with everyone, Wu Hao found a cool place to sit down, and then some staff brought some fruit cold drinks.

In such a high-latitude desert, it is actually noon hot for a while, as long as you avoid the sun, the temperature is OK. Even at night, the temperature will drop a lot, and you will feel cold at night, and the temperature difference between day and night is large.

"Introduce the two experimental rockets briefly. They only looked at the materials and didn't know much about them." Wu Hao pointed to some of the entourage who followed him this time.

OK, Yu Chengwu nodded, and then preached at the crowd: "This launch experiment, we prepared a total of two rockets. They are ultra-low-cost disposable rockets using 3D printing technology and materials, and recycling technology. The returnable reusable experimental rocket ~ www.readwn.com ~ These two rockets represent the development direction of these two rocket technologies, one is the use of ultra-low-cost disposable rockets. The biggest technical difficulty of this type of rocket It is to reduce the launch cost as much as possible under the premise of ensuring safety and reliability, thereby improving the market competitiveness of such rockets.

The second one is also a way to control costs. That is to use recyclable technology to re-launch the intact rocket after launch for two or more repeated launches. "

"I know this, it's like SPX's Falcon 9 rocket. Have we developed this technology?" Zhang Jun said in front of his eyes.

And hearing Zhang Jun's words, everyone also looked at Yu Chengwu, and couldn't help but be surprised. They wouldn't really make this technology out, it would be too unreal.

Seeing everyone ’s reactions, Yu Chengwu shook his head with a smile: "The recyclable technology of the SPX Falcon 9 rocket is too complicated. We haven't mastered it yet, but we thought of another retractable technology.

In fact, it is not a new technology. Lao Mi used it decades ago. That is to use a parachute to slowly lower the first stage of the rocket after launch without crashing, so as to achieve the purpose of recovery.

Of course, compared to technology decades ago, we have also innovated on this. For example, through the grid plate rudder, we can control the landing place of the rocket and better control the landing point accuracy.

In addition, when the rocket is about to land, it will instantly re-ignite the main engine to play a reverse thrust. So as to further slow down the ground speed, reduce the impact on the rocket arrow body. "

"Beggar version?" Hearing this, Zhang Jun could not help but open his mouth. After thinking for a long time, he jumped out of these words.

Hahahaha ... Everyone heard a laugh and laughed.
