Military Technology

　　 At 4:30 in the afternoon, 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 under martial law.

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

　　 Because of this, on the desert road far away from the base, many astronomy enthusiasts who got news in advance and many tourists watching the excitement gathered.

　　 So this has not yet launched, and related news and information have flooded 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 commercial launch vehicle of commercial interest."

　　 "As long as there are many stereotypes, everyone can be number one."

　　 "Keyboardman, don’t say anything else, just say that this wireless technology is absolutely advanced in the world."

　　 "Don't blow it, it's still unknown whether it will succeed or not."

　　 "Hope to succeed, this is a huge overflight of domestic aerospace technology and private aerospace industry."

　　 "I like Wu Hao, don't talk about it, you can see the truth in your hand."

　　 "Really, Wu Hao is more pragmatic, and he has achieved what he said."

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

　　 "It goes without saying, of course the Falcon Rocket is stronger."

　　 "Strong foreigners, everything is foreign."

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

　　 "Yes, but you can't make generalizations. These two technologies have advantages and disadvantages. Regardless of the technology, as long as the rocket can be successfully launched and landed safely."

　　 "Yes, black cat and white cat, catching mice is a good cat."

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

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

　　 To put it bluntly, our country does not have engines for rockets to work for a long time. Note that it is a long time here, which has stricter or even harsher requirements for engine technology, especially materials.

　　A general one-off rocket has no such concerns. Their task is to be able to work safely and stably for tens of seconds and hundreds of seconds, and then die.

　　 But the retractable rocket, not only the engine needs to work normally and stably during the entire launch process, but also the rocket engine is still working during the landing. This adds up to the operating time of the rocket engine, which is difficult to compare with a general one-off rocket.

　　 And this is just one mission. Like a 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" retractable commercial launch vehicle's first-stage rocket body is designed to be reused six to seven times or more. .

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

　　 Haoyu Technology uses this combination of parachute and rocket engine landing technology, which seems to lag behind the Falcon rocket’s direct use of the engine to land.

　　 But in fact, it is also very complicated and difficult. Although there are more parachutes, it may weigh hundreds of kilograms more, but this part of the weight can completely save the fuel used in the landing of a rocket of almost the same volume.

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

　　Because there is a parachute that slows down during the landing process, the engine can be temporarily turned off, and then restarted when it is close to the ground, so that the landing speed is within the safe landing speed.

　　 In this way, not only does it save fuel, but more importantly, it saves the working time of the rocket engine. This is really calculated by the second, which is worth a second.

　　 So don't underestimate this method of landing, it is actually very advanced. There are not many countries that can implement this technology, let alone companies.

　　 If this launch can be successful, it will surely be a comfortable and influential stroke in the domestic aerospace technology field and even the world aerospace technology field. This also means that the domestic commercial aerospace market will usher in new opportunities, and the launch prices of various spacecraft including satellites will also be further reduced. "

　　 "What age is it, and I still post a long article. If I have this time, I might as well go chat with the young lady. I deserve to be single."

　　 "I have said so much, what impact does this have on our general public."

　　 "If the country is strong, the people are rich, how can it not affect it."

　　 "I'll answer it. 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 our general public. The most common one is our Beidou navigation system. Although it looks very 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 taxis, ordering food, etc., which also depend on the Beidou navigation system ~www.readwn.com~ Secondly, it is the communication system. TV satellite antennas, maritime satellite phones, etc., as well as Musk’s Starlink project, 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 the construction of this'Hongyan' project.

　　 Finally, confide some 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, this is the real boss!"

　　 "Boss, where's the internal news, 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 launch next year, and it looks like a normal spacecraft."

　　 "For example, similar to the X37B and our country's very mysterious returnable unmanned spacecraft?"

　　 "I'll go, if it is, that would be awesome."

　　 "It's impossible, but how can a private company of Haoyu Technology be qualified to intervene in this field with the kind of strategic weapons and equipment at the national level."
