Chapter 943: It doesnt matter if its a black cat or a white cat, as long as it catches mice, its a good cat
At 4:30 in the afternoon, Wu Hao accompanied Erma to the observation station of the launch site.
The rocket launch has entered the final countdown stage, so the entire launch site and even the entire base have been placed under martial law.
This launch is semi-open, so many reporters from the media were invited to witness the entire launch and recovery process.
Therefore, on the desert road far away from the base, many astronomy enthusiasts who had received the news in advance and many tourists watching the excitement gathered.
So this also means that before the launch, relevant news and information are already flooding 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 officially launched commercial retractable launch vehicle."
"As long as there are many formulas, everyone can be number one."
"Keyboard Warrior, if nothing else, just say that this retractable technology is absolutely advanced in the world."
"Don't brag yet, we still don't know whether it will be successful or not."
"I hope it will succeed. 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 nonsense, you can see the truth in your hands."
"It's true that Wu Hao is a more pragmatic person, and everything he says comes true."
"I heard from experts earlier that the landing method of this rocket will be different from that of the Falcon rocket, which uses a combination of parachute and engine recoil. Is this method better than the landing and recovery method of the Falcon rocket?"
"Needless to say, of course the Falcon Rockets are stronger."
"Li Wai La Tong, foreign countries are powerful in everything."
"That's right. I'm at the forefront in developing rocket technology. Isn't that an objective fact?"
"Yes, but we can't generalize. The two technologies have their own advantages and disadvantages. No matter which technology is used, as long as the rocket can be launched successfully and land safely."
"That's right, a black cat or a white cat is a good cat if it catches mice."
"In fact, Haoyu Technology can adopt this technology, which shows that they are very smart and have fully utilized our own strengths and avoided shortcomings.
The shortcomings of Haoyu Technology, or the shortcomings of our entire domestic aerospace industry, are rocket engine technology.
To put it bluntly, we do not have an engine in China that allows rockets to work for a long time. Note that this is a long time, which has stricter and even harsh requirements for engine technology, especially materials.
Ordinary disposable rockets have no such concerns at all. Their mission is to work safely and stably for tens to hundreds of seconds, and then die.
As for the retractable rocket, not only does the engine need to work normally and stably during the entire launch process, but the rocket engine is still working during landing. This adds up to the working time of the rocket engine, which is difficult to compare with ordinary disposable rockets.
And this is just one mission. Like the Falcon rocket, the longest one can currently perform four or five launch and recovery missions.
According to the official information released by Haoyu Technology, the first-stage rocket body of Wu Hao's 'Jianmu-2' retractable commercial launch vehicle is designed to be reused six to seven times, or even more.
.
As a result, there are very high requirements for the quality of the rocket engine and even the entire first-stage rocket body.
The landing technology that combines parachutes and rocket engines used by Haoyu Technology seems to lag behind the Falcon rocket's direct use of engines for landing.
But it is actually very complicated and difficult. Although the additional parachute may weigh hundreds of kilograms more, this weight can completely save the fuel used in the landing of a rocket of almost the same volume.
Moreover, this kind of parachute can be reused, which will further reduce the cost of a single launch.
Because the parachute plays a decelerating role during the landing, the engine can be temporarily shut down and restarted after it is close to the ground, so that the landing speed reaches a safe landing speed.
In this way, it not only saves fuel, but more importantly, saves the working time of the rocket engine. This is really calculated in seconds, and one second is worth a thousand dollars.
So don’t underestimate this landing method. It’s actually very advanced. Currently, there are only a few countries that can implement this technology, let alone companies.
If this launch can be successful, it will definitely make a mark in the field of domestic aerospace technology and even the world's aerospace technology. This also means that the domestic commercial aerospace market will usher in new opportunities, including satellites.
The launch prices of various spacecraft will also be further reduced."
"What age are you, and you still post long articles? If you have this time, you might as well go chat with the young lady. You deserve to be single."
"Having said all this, what impact does this have on us ordinary people?"
"A strong country makes its people rich, so how could it not have any impact?"
"It's up to me to answer. Let me reply to the brother above. I already have a child. How about you?
The development of aerospace technology is also very closely related to us ordinary people. The most common one is our Beidou navigation system. Although it seems very high-end 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 takeout, etc., these also rely on the Beidou navigation system.
Secondly, there is the communication system, including the previous TV satellite antennas, maritime satellite phones, etc., as well as Musk’s Starlink plan, etc.
In fact, our country also has its own Starlink project, named 'Hongyan', but due to launch costs and related technologies, it has not been implemented on a large scale. If this rocket is successfully launched this time, it will greatly promote this project.
Construction of the 'Hongyan' project.
Finally, let me share some inside information. Haoyu Technology is currently developing its own spacecraft and plans to launch it next year. If successful, it will be one of the few technology companies in the world that can launch spacecraft."
"Holy crap, 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 that fast. The boss said it will be launched next year. It looks like an ordinary spacecraft."
"For example, similar to the X37B and our country's very mysterious returnable unmanned spacecraft?"
"I'll go, if so, that would be awesome."
"It's 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."
