“Even ordinary fairings cost over one million, with the lowest ones costing hundreds of thousands.
If the fairing can be recycled, this means that such a cost can be saved. Based on the average use of each half fairing ten times, then the cost spread to each launch is very low, only one-tenth
, and the money saved ten times is also a very considerable amount."
Director Zhang nodded and said: "There are currently only a handful of companies that can master fairing recycling and reuse technology. Compared with other companies and countries, Haoyu Aerospace's fairing recycling technology is more reliable and cheaper. It can be said that it is
Representative of fairing recycling technology.”
After talking about this, Director Zhang pointed to the second part of the rocket model and said: "This is the core second-stage part of the rocket, commonly known as the second-stage rocket. This is also the only part of the Jianmu-9 heavy rocket that cannot be recycled.
We can see that the second-stage rocket is very short, about half as long as the first-stage rocket, but it is very important. It will relay the first-stage rocket to transport the spacecraft payload to the Earth-Moon transfer orbit.
Because it has to leave the atmosphere, its recovery is very difficult, which is equivalent to the difficulty of our manned spacecraft returning to the atmosphere and landing. Moreover, the cost of recovery is also very high, so it is generally not recycled.
Moreover, the second-stage rocket accounts for a relatively small proportion of the overall cost of the rocket, only about 20%, which is a relatively low proportion, so the recycling value is relatively low.
Of course, in recent years, aerospace agencies and aerospace companies have begun to develop recycling and reuse technology for the secondary parts of rockets. As far as I know, Haoyu Aerospace is also a leader in this field.
At present, they have also successfully recovered the second-stage rocket part, and the experiment was a complete success."
After quickly finishing this part, Director Zhang pointed to the bottom part of the model: "This is the core first stage of the rocket and the two boosters. You can see the thickness of the core first stage rocket and the two boosters.
The length is actually the same.
This is because both the core first-stage rocket and the two boosters are actually the core first-stage rocket of the Jianmu-7 rocket. In other words, this Jianmu-9 heavy-lift launch vehicle is actually a variant or version of the Jianmu-7 rocket.
Enhanced model.
Through modular design, Haoyu Aerospace can combine these modules to form a new rocket.
The advantage of this design is that it greatly saves costs. For example, the core first-stage rocket and two boosters on this Jianmu-9 heavy-lift launch vehicle are actually used N-hand goods. From this aspect
, which has greatly reduced the launch cost of this rocket.
Another difference from conventional rockets is that we can see the position below the core first-stage rocket and the two boosters. This is the rocket landing frame, but it is folded upward. When it lands,
It will open up and land.
This also makes this launch another highlight, that is, we can see the spectacular sight of the core first-stage rocket and the two boosters falling at the same time."
This is the rocket part. Director Zhang put the rocket model aside, then picked up the lunar cargo spacecraft system model he was visiting next to him, and introduced it to everyone.
"This is the lunar cargo spacecraft system model of Haoyu Aerospace. As you can see, it is very similar to a general detector. It is mainly divided into two parts: the upper part, which is the lander at the front of the spacecraft, and the lower part.
That is the orbital module at the rear end of the spacecraft.
Let’s talk about the front lander first. This is the most important part of the entire lunar cargo spacecraft system. It is not only the lander for the spacecraft to land on the moon, but also the core of the entire cargo spacecraft, which is the cargo warehouse.
We can see that in order to carry the maximum amount of cargo, the entire lander is designed to be very large. The cargo warehouse is placed in the middle, and around the cargo warehouse is the entire landing system, including attitude engines, landing engines, etc., which will
This will provide the lander with enough power during the landing process to decelerate the lander so that it can land safely and smoothly on the moon.
The following one is the orbital service module of the spacecraft, which provides power for the entire lunar cargo spacecraft, including orbit correction during the Earth-moon transfer phase, braking and orbit changes when entering the lunar orbit, etc.
At the same time, we can see that there are two solar system battery sails on both sides of the orbital service module, which will also provide power supply for the entire lunar cargo spacecraft system during flight."
After listening to Director Zhang's introduction, the host nodded and then asked a question that he was more curious about: "Director Zhang, why is the design of the lander of this spacecraft so... rough? It feels like it is unfinished."
Hahaha……
Director Zhang and Professor Huang laughed after hearing the host's words.
Director Zhang smiled and said: "You asked a very good question. In fact, many of us felt the same way when we saw this lunar cargo spacecraft. It felt like it was unfinished, and there were cables everywhere.
The engine nozzle is not neat at all, it feels ugly.
But in fact, this is a very good practical design. It is also very similar to the style of Haoyu Technology, the parent company of Haoyu Aerospace. In other words, it is a line of inheritance, which insists on practicality as the leading factor.
So we will see it as messy and rough, but this actually greatly reduces the unnecessary weight on the spacecraft, so that it can load cargo to the maximum extent. In the view of Haoyu Aerospace's technical engineers, the appearance is not good.
It’s not important to look good, what’s important is performance and reliability.”
Professor Huang on the side laughed and said: "Actually, when we look carefully, its appearance looks rough, messy, and ugly, but in fact, the design is very surprising and sophisticated, and every design has been fully considered.
For example, you can see that the engine nozzle of this lander is in this position. Why is it placed in this position? This is also to prevent the tail flame or high temperature emitted by the engine from affecting the lander itself.
And another very important point is that the lander is designed like this so that it can be easily disassembled."
Dismantle? The host asked puzzledly.
Professor Huang nodded: "Yes, these landers have no use after landing on the moon and cannot be wasted. Therefore, the engineers of Haoyu Aerospace designed this design mainly to facilitate the dismantling of the landers later.
Make full use of these materials and parts on the lander for the subsequent construction of the lunar surface scientific research station, as well as for the maintenance and replacement of some equipment parts."
