"Military Technology (

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 higher-level propulsion unit.

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

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

After all, regardless of whether it is the first-level or 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 helicopter, it may be difficult to lift.

As for the method of combining multiple heavy-duty helicopters for recovery and transportation, the coordination of multiple helicopters is also a problem.

Even the combination of multiple heavy-duty helicopters at such a close distance is full of many uncertainties and dangers.

The fairing itself is relatively light, coupled with the paraglider decelerating, the speed is relatively slow, and it is also suitable for helicopters for aerial capture.

The successful completion of these two launches and recovery marks that Haoyu Aerospace has become the second private company in the world that has mastered the recovery technology of the first-stage rocket body and fairing of the rocket.

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

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

Of course, domestic commercial aerospace launch orders only need to be approved by the 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 overall suppression of this aspect by Europe and the United States, it has also made it difficult for them to obtain commercial satellite launch orders from many European and American countries, even if they are private enterprises.

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

So the development space left for them is still very small, but not without it. For example, they successfully won the launch order for a small communications satellite from a certain 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 perspective, the development prospects in this field are also very broad.

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

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

For example, Xiao 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 the little Ma wearing a white shirt in the video, Wu Hao's mouth turned up slightly.

Xiao Ma, although he is relatively low-key, he has a good personality. Whether he is a man, he is very gentle and elegant, which makes a good impression.

Since getting acquainted with Xiao Ma, the two have also had a lot of anxiety. Sometimes they would call or message each other to greet each other, and the relationship has gradually become familiar.

Xiao Wu, congratulations. The two launch missions were not only a complete success, but the recovery was also quite successful. Unexpectedly, how long it took you to achieve such results is really amazing.

Oh, thanks. Wu Hao smiled and thanked him.

Xiao Ma smiled in the video: "How did you come up with this kind of recycling method is really whimsical and amazing."

"This way of charging is not the first thing we thought of. It was actually thought of by others, but we made relevant improvements and optimizations on this basis, and this time the experiment was successful." Wu Hao explained with a smile.

I am very curious about how much money this fairing will be able to save for you if it is successfully recycled, and how much money the entire recycling work will cost. Xiao Ma asked questions 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 directly smiled and answered: "The entire fairing is divided into two halves. Although it is only a two-half protective shell, it is actually relatively expensive. The entire production is completed. It takes about one or two million to transport it 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 cost of recovery, it is relatively low, about 100,000 yuan. "

Hearing Wu Hao’s answer, Xiao Ma nodded, UU read www.uukánshu.com and said: “In this way, your first-stage rocket and fairing together can leave almost 80%. The above rocket manufacturing cost expenses."

Hearing this, Wu Hao waved his hand again and again: "It can't reach that much, probably about 60% to 70%. The cost of a secondary rocket is still relatively high.

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

"It can save 60 or 70%, which is already very good. Then, can this second-level rocket be recycled?" Xiao Ma immediately asked another question that he was interested in.

In response, Wu Hao shook his head: "There is no technology in this area. The recovery of the secondary rocket is too difficult. Especially since it needs to pass through the atmosphere twice, the friction burn damage to the secondary 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-stage rocket body is almost half cheaper than that of the first-stage rocket body. In addition, the recovery of the second-stage rocket is large and the cost is high, so it is basically not worth much. There is no need for this. "

Hearing Wu Hao's words, Brother Xiao Ma nodded, and then said to Wu Hao with a serious face: "After returning from the launch site of your Northwest R&D Center last time, my heart is more lighted than you.

I also want to try to enter the field of space 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. At present, this laboratory is researching a data communication experimental satellite for us. We hope to be able to launch on your rocket. "
