"Then buy a new one, it won't cost a few more bucks anyway." Zhang Jun's face was happy, for him or for everyone, the new one is definitely better than the second-hand one.

In their small talk, the convoy gradually drove to its destination, a rocket launch test site at the end of this desert road.

This is also a rocket launch test site that Wu Hao has just completed in the northwest desert, and the entire rocket launch test site covers a total area of 10,000 mu. However, only a small part of the effective land is used, and the rest is vacant land, and drought-tolerant trees and vegetation will be planted in the future.

In order to facilitate the transportation of rockets and equipment, they also specially built a desert asphalt road to connect provincial highways and highways, and extended all the way to the rocket launch test site in the hinterland of the desert.

Of course, this rocket launch test site was not built casually, not only needs to be explored in advance, but also needs to apply for reporting, and it is very cumbersome to coordinate with local and even multiple departments. Fortunately, the space authorities have formulated a complete set of regulations and standards for the private aerospace industry, and 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 arrived, they found that the buildings of the entire base were actually some prefabricated houses and containers.

Because the time is so short, the construction of the infrastructure of the entire base has not yet had time to begin. Therefore, at present, only some prefabricated houses and some offices converted from containers have been installed for the launch experiment at this stage.

"Mr. Wu, Mr. Zhang, welcome!" Yu Chengwu led a group of people forward and warmly shook hands with them and welcomed.

"It's too desolate."

Zhang Jun looked at the surrounding environment with a sunhat and sunglasses, and couldn't help but exclaim: "Have you stayed in this environment for more than half a month, it's really not easy." ”

"Hehe, it's nothing, we're all used to it." Yu Chengwu smiled at Zhang Jun and grinned at his white teeth. It may be that the time spent in the scorching sun is a little long, so this goods has changed from a handsome guy who was white and clean, and now he is tanned and swarthy, and I don't know where he thinks he is moving bricks and working under the coolies.

"Why do you see you alone, Xiang Ming?" Wu Hao asked, looking around.

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

"When will it be launched?" Zhang Jun couldn't help but ask.

"The launch window given to us by the competent authorities is from 3:30 p.m. to 8 p.m., so we have plenty of time to prepare. We tentatively planned to launch the first experimental rocket at 4:50 p.m. and the second at 6:00 p.m., with an interval of one hour and ten minutes.

That way, we have plenty of time to prepare. However, this time is not accurate, and the desert is prone to gusty winds, and if the wind speed is too high, the launch time may have to be delayed. ”

Wu Hao nodded when he heard this, since they were all decided, then he wouldn't say anything anymore, everything would come according to their plan.

"I came to bring you some condolences this time, and you arranged for someone to share them with you. It's been a hard time, so I'll invite you to a big dinner when I go back. Wu Hao smiled at the crowd surrounding him.

"Hahaha, thank you Mr. Wu, long live Mr. Wu!" When a group of scientific researchers heard this, they all laughed and cheered.

Everyone is young, so they are very serious about doing this kind of business that they are interested in. Although it was a bit hard, everyone enjoyed it. And Wu Hao is not bad for them, not only has a generous salary, but more importantly, Wu Hao's appetite for them, everyone is also convinced and agrees with this big boss from the bottom of their hearts.

"Okay, don't stand in the sun, don't think you're dark, find a place to take refuge. By the way, the condolences I brought this time included some sunscreen and sunscreen equipment, and you should remember to use them when you look back, especially girls.

Originally, all the girls and guys were very beautiful and handsome, but they have only been in the desert for a few days, and they have been sunburned like this. If you don't take good care of it, your boyfriend and girlfriend won't want you anymore, so don't rely on me then. ”

Hahahaha......

After joking and laughing with everyone, Wu Hao and the others found a shady place to sit down, and then a staff member brought some fruit and cold drinks.

In this high-latitude desert area, it is actually hot at noon, as long as you avoid the sun, the temperature is okay. Even at night, the temperature drops a lot, and it feels even colder at night, with a large temperature difference between day and night.

"Let's briefly introduce these two experimental rockets, they have only read the information, and they don't know much about it." Wu Hao pointed to some of the entourages who followed him this time.

Okay, Yu Chengwu nodded, and then said to everyone: "For this launch experiment, we have prepared a total of two rockets. They are ultra-low-cost disposable experimental rockets using 3D printing technology and materials, and returnable reusable experimental rockets using recycling technology.

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 is to reduce the launch cost as much as possible under the premise of ensuring safety and reliability, so as to improve the market competitiveness of this type of rocket.

And the second is also a way to control costs. That is to use recyclable technology, the rocket after launch is well recovered for secondary or multiple repeated launches. ”

"I know, it's like SPX's Falcon 9 rocket, have we developed this technology?" Zhang Jun's eyes lit up.

Hearing Zhang Jun's words, everyone also looked at Yu Chengwu, and they couldn't help but be surprised. It's not really going to come out, it's too unreal.

Seeing everyone's reactions, Yu Chengwu shook his head with a smile and said, "The recovery technology of SPX's Falcon 9 rocket is too complex for us to master, but we have thought of another retractable technology.

In fact, it is not a new technology, Lao Mi used it decades ago. That is, the parachute is used to slowly descend the first stage of the rocket after launch, so as to achieve the purpose of recovery.

Of course, we're also innovating on this compared to the technology of a few decades ago. For example, through the grid plate rudder, we can control the landing site of the rocket, and the landing point accuracy is better.

In addition, at the moment when the rocket is about to land, it will also instantly re-ignite the main engine and play a thrust reverser. In this way, the landing speed is further slowed down and the impact on the rocket body is reduced. ”

"Beggar's version?" Hearing this, Zhang Jun couldn't help but open his mouth, and after thinking for a long time, he popped out these words.

Hahahaha...... Everyone laughed when they heard this.
