Chapter 251 Regret
There are many aerospace enthusiasts in China, and we know that although this thing sounds simple, it is really not easy to do.
The biggest difficulty is the power system and control system of the rocket recovery device.
You have to be very awesome to do this.
After finally successfully recovering the complete rocket with parachute from the Gobi Desert in the northwest, the entire barrage was boiling.
"Witness history"
"Call the starship over, call the starship over, I'll let you call the starship over!"
"This is always purely original technology, right? Let's talk about light armor aerospace Are you following the people behind SpaceX for a walk?”
“Dai Gaolong is calling the hotline, is this technology for sale?”
“Let me go quickly!”
< br>
"If we don't let people go, we will let dogs bite people."
The veterans on Zhihu are even more enthusiastic. Compared with the emotional speeches in the live broadcast room, experts from all walks of life have emerged.
This is determined by the background of the community. Zhihu, as the favorite of small town essayists, naturally has a unique obsession with technological progress.
But this time, among the answers on Zhihu, the one with the highest number of likes was the answer from a certain key political blogger:
“I just want to say that this time Lao Zhong is very obvious. Show your sword, the technology itself is amazing and dazzling
What I want to say is something other than technology.
During the live broadcast, engineers from China Aerospace and Guangjia Aerospace also introduced to us that the space recovery device can be regarded as a module of the space station.
This means that after the future Light Armor Space Station is launched into space, they are serious about space mining. Space paint automation is only the first step in the entire space mining attempt.
I can see that Guangshen and Guangjia Aerospace are moving step by step towards the goals they have set. The cooperation with Huaguo Aerospace also allows me to see Huaguo start business. Hope for the future of spaceflight.
Speaking of Liang Jian, the federation detained all the engineers who asked Guangjia Aerospace to communicate on the grounds of the murder of black people. This is definitely unacceptable to China.
What's the situation now and you, America, are still doing this?
The live broadcast of the entire recovery process of Shenzhou-Guangjia proves that we are not bragging when we say the recovery rate is close to 100%. A rocket launch can be completed using only electric energy, which means that the cost can also be Gives you compression to a very low level.
A launch only requires electricity, the loss of the rocket itself, and thermal insulation coating.
I don’t know whether it can achieve the 100 yuan per kilogram that Guangshen claimed in the interview, but it is definitely lower than the traditional rocket launch method, which is unimaginable.
I read a very obscure message from it. Guangjia Aerospace has never cooperated with Da Mao and has never helped Da Mao launch satellites.
But this time is different. If American does not put the people back and Guangjia Aerospace uses the latest electric-driven rocket technology to help Da Mao launch satellites, what will American and Europe do?
During the fight between Da Mao and Er Mao in 2022, why did the two sides go back and forth? Da Mao had almost no air control. Starlink and GPS were banned, resulting in Da Mao’s air defense system still living in the previous era.
Once Guangjia Aerospace helps Da Mao take on the work of launching satellites, Da Mao will gain a huge advantage if he starts a war again.
In the past, you could do it without air supremacy. If you had air supremacy, how could Ermao resist?
The advantage of satellites is that they can be deployed quickly and achieve their goals within seconds.
In the past, the cost of satellites was too high. To conduct fixed-point reconnaissance, they needed to be deployed, changed orbits, and consumed satellite fuel. Fuel is the life of the satellite.
Now not only has the cost of satellite launch been reduced for you, but if there is no fuel, you can rely on quantity to make up for it. If the real-time performance is poor, just launch a few more satellites.
Multiple satellites are required to change orbits to cooperate with monitoring, and the cost is even lower than the original single satellite. Satellites have poor real-time performance and cannot stay over the target. To maintain continuous monitoring, multiple satellites need to change orbits and come over for replacement, which makes the cost even higher.
In short, the low cost of launch means that once Guangjia Aerospace is willing to provide this set of launch services to Da Mao, Da Mao can eliminate all disadvantages by relying on the number of launches.
Even satellites can be handed over to China to help them build them. The satellites made by China are cheap and easy to use. If he doesn't buy a batch of these big hairs to make two cents, he will definitely not be able to do it.
If Amerikan doesn’t let him go, then we will have to export ultra-low-cost rocket launch services to Da Mao. This is a naked threat. "
The external Internet is more about discussing technical details, discussing how incredible this technology is, and why Amerikan can't do it.
"About the electronic launch of Guangjia Aerospace and Huaguo Aerospace. Americen has made similar attempts in the past to drive rocket launch and recovery.
It was the first orbital-class rocket to use an electrically driven turbopump as a fuel-driven component.
Both its first and second stages use electric-driven turbopump engines, in which the electric pumps are powered by lithium batteries. The second stage uses three hot-swap batteries. Once the batteries are exhausted, they will be discarded directly to reduce the mass of the rocket.
The rocket’s first stage has nine engines and the second stage has a vacuum-optimized version of the engine. Almost all engine parts are 3D printed. The main body of the rocket is built with lightweight carbon fiber composite materials
In other words, if we can also launch a rocket recovery device in space, we can also make the rocket be received by the space recovery device and then repaired. Finally it returns to Earth.
Why I know its parameters so clearly is because I used to be an engineer for this company. We started our first launch in 2017 and successfully launched it in 2018.
It is even similar to China’s rocket in terms of launch mass, also within 150 kilograms.
The technical solution used by Huaguo this time is the technical solution we proposed back then.
By adding a rocket recovery device in space, the rocket can be repaired in space and returned to Earth.
This can reduce the cost to US$10 per kilogram.
But we failed because investors refused to invest money and NASA did not give us orders. For them, supporting SpaceX is far more important than supporting other commercial aerospace companies.
Even if our solution was so advanced, even if we only needed another $200 million at that time, we would have succeeded.
In recent years, the technological gap between American and China comes from creativity. In my opinion, American has lost its creativity, and we dare not invest in radical technical routes and solutions.
Seeing that the Chinese people have realized our dreams back then, I don’t feel sorry, I just feel happy.
Today’s NASA is no longer the NASA of 50 years ago. There are a bunch of rotten bureaucrats inside who only want to invest resources in SpaceX.
Once there are results, it is due to NASA's good leadership and the credit of NASA. Once the launch fails, it is SpaceX's problem, and Musk will come out to help them attract firepower.
It is this group of bureaucrats that led to the rapid mediocrity of NASA, and SpaceX is the freak they raised”
George was typing on the keyboard very fast. As a former Rocket Lab engineer who is now laid off, he cried while watching the Shenzhou-Guangjia live broadcast channel of an aerospace enthusiast on YouTube in the early hours of the morning.
The scene where Hua's rocket recovery device went to capture the Shenzhou-Guangjia appeared in his dream. It would have been possible if they had received investment.
The result was realized by the Chinese.
After George came across related questions on Quora, his thoughts were drawn back to two years ago. When they were disbanded, the plan they failed to implement due to NASA's shortsightedness was accomplished by the Chinese.
George was filled with indignation and frantically vented his inner dissatisfaction on Quora. The ringtone of the iPhone next to him rang.
"Hello, George? Ready to come back to work."
