Of course, the upper stage is only used for launching missions with special requirements such as multiple satellites with one arrow, high orbit and precise orbit. Under normal circumstances, there is no need for a propulsion unit of the upper level.

After all, the upper level also needs to spend money, and it is expensive.

In fact, the method proposed by these experts has been questioned and disputed.

After all, no matter whether it is the first-level rocket body or the second-level rocket body of the rocket, 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 a high altitude, even with a paraglider, But with such a large acceleration, even if it is captured by a heavy-duty helicopter, it may be difficult to lift it.

As for the combination of multiple heavy-duty helicopters for recovery and transportation, the cooperation of multiple helicopters is also a problem.

Even the combination of multiple heavy-duty helicopters in such a close range is full of uncertainties and dangers.

As for the fairing, it is relatively light in itself, coupled with the deceleration of the paraglider, 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 recovery marks that Haoyu Aerospace has become the second private company in the world to master the recovery technology of the first-stage rocket body and fairing.

And from the perspective of cost, Haoyu Aerospace's Jianmu-2 rocket has a cost competitive advantage.

However, even this kind of commercial aerospace project has its own particularity and complexity, and not all orders can be accepted.

Of course, domestic commercial space launch orders only need to be approved by relevant departments, so this 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, as well as the comprehensive suppression of Europe and the United States in this regard, this also makes it difficult for them to obtain commercial satellite launch orders from many European and American countries for commercial space launch missions even if they are private enterprises.

Therefore, their overseas launch orders are generally from some developing countries, even underdeveloped countries. In this regard, it is difficult for them to compete with the national team.

So there is still very little room for development left for them, but it is not impossible. For example, they successfully won an order to launch a small communication satellite in an African country.

Of course, the current domestic aerospace field is developing rapidly, especially in the field of microsatellites. With the current launch prices getting lower and lower, more and more companies and scientific research institutions are developing their own microsatellites.

So from this point of view, the development prospects in this field are also very broad.

Moreover, Haoyu Aerospace will launch its own related space payloads soon, including experimental spacecraft, satellites and so on.

With the reports of various media, these two launch missions have also attracted the attention of many people, even many industry leaders and old acquaintances of Wu Hao.

For example, Brother Xiao Ma, who personally visited the launch base of the Northwest R\u0026D Center, called Wu Hao after the two launch and recovery missions.

Looking at the pony brother 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, he has a good personality. No matter how he behaves in the world, he is very gentle and elegant, which makes people impressed.

Since getting acquainted with Xiao Ma, the two have also had a lot of anxiety, and sometimes they will call or message each other to greet each other, and the relationship has gradually become 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 it to be so long, and you have achieved such results, which is really amazing.

Oh, thank you. Wu Hao thanked with a smile.

Brother Xiao Ma laughed in the video: "How did you come up with this recycling method? It's really whimsical and amazing."

"This method of charging fees is not our first idea. It is actually someone else's idea. It's just that we have made relevant improvements and optimizations on this basis.

The experiment was successful this time. " Wu Hao explained with a smile.

I am very curious about how much money this fairing will leave for you if it is successfully recycled, and how much the entire recycling work will cost. Brother Xiao Ma immediately asked him a question that he was more concerned about.

As for Wu Hao, he smiled when he heard this question. In fact, many people have already asked him this question, so Wu Hao replied directly with a smile: "The whole fairing is divided into two halves. Although it is only two halves of the protective shell, it is actually quite expensive. It takes about one or two million to transport to the launch site for assembly.

If it can be recovered smoothly, it will leave us with more than one million launch costs.

As for the recovery cost, it is still relatively low, about a hundred thousand or so. "

Hearing Wu Hao's answer, Brother Xiao Ma nodded, and then said: "In this way, your first-stage rocket and fairing will add up, and you can almost leave more than 80% of the rocket manufacturing cost." .”

Wu Hao waved his hands again and again when he heard the words: "It can't reach that much, it's about 60% to 70%, the cost of the second-stage rocket is still relatively high.

Of course, compared with traditional disposable rockets, the launch cost is naturally much lower, and the corresponding launch cost will also be much cheaper. "

"Sixty to seventy percent can be saved, which is already very good. Then, can this second-stage rocket be recycled?" Brother Xiaoma immediately asked another question that he was interested in.

In this regard, Wu Hao shook his head: "There is no such technology at present, and the recovery of the second-stage rocket is too difficult. Especially it needs to pass through the atmosphere twice, and the friction and burning damage to the second-stage rocket body is 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-level rocket body is almost half cheaper than that of the first-level rocket body. In addition, the recovery of the second-level rocket is large and the cost is high, so it is basically not worth much when it is offset. There is no need for this anymore. "

Hearing Wu Hao's words, Brother Xiaoma nodded, and then said to Wu Hao seriously: "After returning from the launch site of your Northwest R\u0026D Center last time, my heart is lighter than yours.

I also want to try to explore 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 set up several spacecraft and miniature research laboratories, and this laboratory is currently working on an experimental data communication satellite for us, which we hope to be able to launch into space on your rocket. "
