Of course, the upper stage is only used for launch missions with special requirements such as multiple satellites in one rocket, high orbit and precise orbit insertion. Under normal circumstances, there is no need for an upper level propulsion unit.
After all, higher-ups also need to spend money, and they cost a lot of money.
In fact, the method proposed by these experts is actually highly questionable and controversial.
After all, whether it is the first-stage rocket body or the second-stage rocket body, even when the fuel is exhausted, the weight of the empty rocket body is very medium, and the acceleration of the rocket body falling from high altitude, even with a paraglider, But with such a large acceleration, even if a heavy helicopter captures it, it may be difficult to lift it up.
As for the method of combining multiple heavy-duty helicopters for recovery and transportation, the cooperation of multiple helicopters is also a problem.
Even the combination of multiple heavy-lift helicopters at such a close distance for recovery and transportation tasks is full of uncertainties and dangers.
As for the fairing itself, it is relatively light, and coupled with the paraglider's deceleration, the speed is relatively slow, and it is also suitable for helicopters to capture in the air.
The successful completion of these two launches and recoveries marks that Haoyu Aerospace has become the second private company in the world to master the technology of recovering rocket first-stage bodies and fairings.
And from a cost perspective, Haoyu Aerospace’s Jianmu-2 rocket has a more cost-competitive advantage.
However, even this kind of commercial aerospace project has its own particularity and complexity, and it does not mean that all orders can be accepted.
Of course, domestic commercial space launch orders only need to be approved by relevant departments, which is naturally no problem. However, the issues involved in foreign commercial space launch mission orders are more complicated.
First of all, due to some well-known reasons and the comprehensive suppression by Europe and the United States in this regard, it is difficult for them to obtain commercial satellite launch orders from many European and American countries even if they are private enterprises carrying out commercial space launch missions.
Therefore, their overseas launch orders are generally from developing countries, even underdeveloped countries. In this regard, it is difficult for them to compete with the national team.
Therefore, the space left for them to develop is still very small, but it is not impossible. For example, they successfully won a launch order for a small communications satellite from a certain African country.
Of course, the domestic aerospace field is developing rapidly, especially in the field of micro-satellites. As the current launch price is getting lower and lower, more and more companies and scientific research institutions are developing their own micro-satellites.
So from this perspective, the development prospects in this field are also very broad.
Moreover, Haoyu Aerospace will soon launch its own related space payloads, including experimental spacecraft, satellites, etc.
With reports from various media, these two launch missions have also attracted the attention of many people, including many industry leaders and Wu Hao's old acquaintances.
For example, Brother Ma, who personally visited the launch base of the Northwest R&D Center, called Wu Hao after the two launch and recovery missions.
Looking at Brother Ma, who was wearing a white shirt and sitting upright in the video, the corners of Wu Hao's mouth turned up slightly.
Brother Xiao Ma, although he is relatively low-key, has a good personality. No matter how he behaves, he is very gentle and elegant, which makes a good impression on people.
Since they met Xiao Ma, the two have had a lot of worries. Sometimes they would call or text each other to greet each other, and their relationship gradually became familiar.
Xiao Wu, congratulations. Not only were the two launch missions a complete success, but the recovery was also quite successful. I didn’t expect that you have achieved such results in just such a short period of time. It’s really amazing.
Oh, thank you. Wu Hao smiled and thanked.
Xiao Ma laughed in the video: "How you came up with this recycling method is really whimsical and amazing."
"This charging method was not the first thing we came up with. It was actually someone else's idea. It's just that we made relevant improvements and optimizations on this basis, and the experiment was successful this time." Wu Hao explained with a smile.
I'm very curious about how much money this fairing can leave you if it is successfully recycled, and how much the entire recycling process will cost. Brother Ma immediately asked him a question that he was more concerned about.
Wu Hao smiled when he heard this question. In fact, many people have asked him this question, so Wu Hao answered directly with a smile: "The entire fairing is divided into two halves. Although it is just two halves of protective shells, it is actually relatively expensive. After the entire production, It costs about one to two million to transport it to the launch site for assembly.
If it can be recovered successfully, it will leave us with more than one million launch costs.
As for the recycling cost, it is relatively low, about hundreds of thousands. "
Hearing Wu Hao's answer, Xiao Ma nodded, and then said: "In this case, your first-stage rocket and fairing combined will leave more than 80% of the rocket manufacturing cost. .”
Wu Hao waved his hands after hearing this and said: "It can't reach that much, probably around 60 to 70 percent. The cost of the two-stage rocket is still relatively high.
Of course, compared with traditional disposable rockets, the launch cost is naturally much lower, and the corresponding launch costs will also be much cheaper. "
"It can save 60 to 70 percent, which is already very good. So what about this second-stage rocket? Can it also be recycled?" Xiao Ma immediately asked another question that interested him.
In this regard, Wu Hao shook his head: "There is currently no technology in this area, and the recovery of the second-stage rocket is too difficult. Especially since it needs to pass through the atmosphere twice, the friction and burning damage to the second-stage rocket body will be relatively large. Therefore, it is generally not eligible for recycling.
And even if it can be recycled, it does not have a high recycling value. The manufacturing cost of the second-stage rocket body is almost half cheaper than that of the first-stage rocket body. In addition, the recycling cost of the second-stage rocket is high, so when the balance is balanced, there is basically not much value, and naturally it is This is no longer necessary. "
Hearing Wu Hao's words, Brother Ma nodded, and then said sternly to Wu Hao: "After I came back from the launch site of your Northwest R&D Center last time, I was even more excited than you.
We also want to try to enter the field of aerospace technology, but don’t get me wrong, we currently have no plans to enter the field of space launch.
We have established several spacecraft and micro-research laboratories. This laboratory is currently working on a data communication experimental satellite for us. We hope to be able to launch on your rocket. "
