Military Technology

At 4:30 p.m., Wu Hao accompanied Erma to the observation station at the launch site.

The rocket launch has entered the final countdown stage, so the entire launch site and even the entire base have been put under martial law.

This launch is semi-open, so many media reporters were invited to witness the launch and the whole process of recovery.

Therefore, on the desert road far from the base, many astronomy enthusiasts who got the news in advance and many tourists who watched the excitement gathered.

So this also makes it not yet launched, and related news and information have been flooded on the Internet.

"666, this should be the second retractable launch vehicle in the world."

"No, many companies and countries are currently experimenting with retractable launch vehicles. This should be the second commercially interested retractable launch vehicle officially launched."

"As long as there are many formulas, everyone can be the first."

"Keyboard Man, if you don't say anything else, just say that the retractable technology is absolutely advanced in the world."

"Don't brag, it's still unknown whether it will be successful or not."

"I hope it can be successful. This is a huge leap forward for domestic aerospace technology and the private aerospace industry."

"That's what I like about Wu Hao, don't talk about it, just see the truth in your hands."

"It's true, Wu Hao is more pragmatic, and everything he says comes true."

"I heard from experts that the rocket's landing method this time will be different from the Falcon rocket, which uses a combination of parachute and engine recoil. May I ask which method is better than the Falcon rocket's landing and recovery method?"

"It goes without saying, of course the Falcon Rockets are stronger."

"Li Wai Latong, everything is foreign."

"It's what it is. In terms of rocket technology, people are at the forefront. Isn't it an objective fact?"

"Yes, but it can't be generalized. These two technologies have their own advantages and disadvantages. No matter which technology is used, as long as the rocket can be successfully launched and landed safely."

"That's right, a black cat is a white cat, as long as it catches mice, it's a good cat."

"Actually, Haoyu Technology can adopt this technology, which shows that they are very smart, giving full play to our own strengths and avoiding weaknesses.

The shortcoming of Haoyu Technology, or what is the shortcoming of our entire domestic aerospace industry, is rocket engine technology.

To put it bluntly, we do not have engines for rockets to work for a long time in our country. Note that this is a long time, which has stricter and even harsher requirements on engine technology, especially materials.

Ordinary one-time rockets have no worries in this regard. Their task is to be able to work safely and stably for tens of seconds and hundreds of seconds, and then die.

As for retractable rockets, not only does the engine need to work normally and stably during the entire launch process, but also the rocket engine is still working during the landing. In this way, the working and running time of the rocket engine is difficult to compare with ordinary disposable rockets.

And this is only one mission. Like the Falcon rocket, the longest one can perform four or five launch and recovery missions.

According to the official information released by Haoyu Technology, Wu Hao's "Jianmu No. 2" can receive the first-stage rocket body of a commercial launch vehicle,

It is designed to be reused six to seven times, or even more.

In this way, there are very high requirements for the quality of the rocket's engine and even the entire first-stage rocket body.

The combination of parachute and rocket engine landing technology used by Haoyu Technology seems to be lagging behind the Falcon Rocket's technology of directly using the engine to land.

But in fact, it is also very complicated and difficult. Although the extra parachute may add hundreds of kilograms of weight, this part of the weight can completely save the fuel used in the landing of a rocket with almost the same volume.

Moreover, this parachute can be reused, which will further reduce the cost of a single launch.

Because the parachute acts as a deceleration during the landing process, the engine can be temporarily shut down, and then restarted when it is close to the ground, so that the landing speed can reach within the safe landing speed.

In this way, not only fuel is saved, but more importantly, the working time of the rocket engine is saved. This is really counted in seconds, a second is worth a thousand dollars.

So don't underestimate this method of landing. It is actually very advanced. At present, there are not many countries that can realize this technology, let alone enterprises.

If this launch can be successful, it will definitely be a great achievement in the field of domestic aerospace technology and even the world's aerospace technology field. This also means that the domestic commercial aerospace market will usher in new opportunities, and the launch price of various spacecraft including satellites will be further reduced. "

"What age is it, and you still post long posts. If you have this time, why not go chat with the young lady, you deserve to be single."

"Having said all that, how does this affect us, the general public?"

"If the country is strong, the people will be rich. How could it have no effect?"

"I'm the one to answer, let me go back to the brother above, I already have a child, how about you?

The development of aerospace technology is also closely related to our ordinary people. The most common one is our Beidou navigation system. Although it seems tall and far away, it is actually closely related to our lives.

The location information on our mobile phones is basically provided by the Beidou navigation system, including when you take a taxi, order food, etc., which also rely on the Beidou navigation system.

Secondly, it is the communication system, the previous TV satellite dish, maritime satellite phone, etc., as well as Musk's Starlink project and so on.

In fact, our country also has its own Starlink project, named "Swan Goose", but due to launch costs and related technologies, it has not been implemented on a large scale. If the rocket is successfully launched this time, it will greatly promote the construction of the "Swan Goose" project.

Finally, a little inside information. Haoyu Technology is currently developing its own spacecraft and plans to launch it next year. If successful, she will also be one of the few technology companies in the world that can launch spacecraft. "

"Damn it, this is the real boss!"

"Boss, where did you get the inside information? What exactly is Haoyu Technology's spacecraft? Is it a manned spacecraft?"

"It can't be a manned spacecraft. It's not so fast. The boss can say that it will be launched next year. It looks like an ordinary spacecraft."

"Such as the returnable unmanned spacecraft similar to X37B and our country's very mysterious?"

"I'll go, if so, that's awesome."

"Impossible, that kind of strategic weapons and equipment at the national level, how can Haoyu Technology, a private company, be qualified to intervene in this field."
