have a thought? "Lao Ma's eyes flashed for a moment and he said excitedly.
"Haha, there are some immature ideas, but these are just ideas. How to implement them depends on the opinions and decisions of the relevant teams." Wu Hao said with a smile.
Seeing that Wu Hao was unwilling to say more in this regard, Lao Ma nodded and didn't ask any more questions. After all, no one would reveal such a major core project casually, and in front of so many people.
As for Xiao Ma, at this time, he took advantage of the opportunity and asked another question: "When can the secondary rocket body be recovered successfully? That would be awesome."
Wu Hao smiled and said: "The second-stage rocket accounts for about 20 to 25 percent of the cost of the entire rocket, which is not a high proportion.
Moreover, the recovery of the second-stage rocket is more difficult, because the second-stage rocket has already rushed out of the atmosphere. It is no less difficult than the current manned spacecraft to return to the atmosphere and achieve a safe landing.
So for so many reasons, no company has implemented this technology yet. However, many similar ideas and plans have been put forward, including many constructive opinions and ideas.
For example, some experts have proposed an eye-catching plan, referencing Musk's interstellar spacecraft structural plan. The rocket's secondary rocket body and payload compartment fairing are joined together to design an aircraft, or rocket body, that can be reused multiple times to perform missions.
The expert's plan is to design the secondary rocket body and load compartment fairing into an aircraft similar to the space shuttle or X37B.
Relying on the retractable first-stage rocket body, the aircraft is sent to the critical space altitude, and then the aircraft engine is started to fly to the target orbit and conduct on-orbit flight.
During its flight in orbit, it can perform a variety of tasks, and its functions are almost the same as those of a space shuttle, such as releasing satellites from the pilot's payload bay and so on.
After completing its on-orbit mission, the aircraft will re-enter the atmosphere, glide using its wings on both sides, then open its landing gear and land on the predetermined runway.
In this way, the entire rocket part can be reused, the cost will be further reduced, and the tasks that can be performed are also very diverse. "
"It's a great idea. If it can be realized, it may become an important means of transportation for humans to travel to space in the future. Its significance is almost equivalent to the invention of passenger aircraft by humans." Lao Ma praised.
As for Xiao Ma, he looked at Wu Hao and asked, "Has this project been approved?"
Wu Hao shook his head: "Not yet, the preliminary technical demonstration work is in progress."
"Oh, what's the problem?" Lao Ma couldn't help but ask.
"The problem is huge. This is a brand-new structural method. There are a series of problems that need to be solved." Wu Hao said with a helpless expression.
Although he said this, the project has actually been launched, code-named "Space Bus".
Judging from the project code name, the name "Space Bus" is to hope that this aircraft can, like a bus, send more people and payloads into space and become a bridge and ladder connecting space and the earth.
Although the project was established, as Wu Hao said, it encountered many difficulties and problems and the differences were relatively large.
Some technical experts believe that we should focus on the mature Jianmu-1 or Jianmu-2 first-stage rocket bodies to design and develop the 'Space Bus' space vehicle.
The advantage of this is that it is robust, there are many mature technologies to learn from, and R&D investment is relatively small. As for the shortcomings, they are naturally obvious. Whether it is Jianmu 1 or 2, the carrying capacity is very limited. It is difficult to transport an overweight spacecraft to the sky, let alone what kind of load it is.
Moreover, the diameter of the rocket body is limited, and the size of the aircraft it can carry is also very limited, so the uses of this type of aircraft are very limited.
Therefore, some experts believe that we can not be limited to our own rockets, but can design and manufacture 'space bus' space vehicles that can be mounted on other rockets.
For example, the Chang 5 rocket, which has gradually matured, has a large enough first-stage rocket body and a booster that can transport heavier loads. Based on this, the project team can completely develop and manufacture an aircraft that is about the same size as a real bus. In this way, whether it is carrying goods or people, its use is very obvious.
This solution is naturally very good, but it also has shortcomings. The first is the investment in research and development. No one can estimate the research and development costs of such a large space vehicle.
The second is the technical difficulty. No matter whether the load or volume is larger by a certain amount, the difficulty will increase exponentially.
Therefore, this expert is worried that it is too risky to invest in such a huge project all at once.
In the end, after intense discussions and considering everyone's opinions, Wu Hao finally decided to invest in the development of small and medium-sized spacecraft that can be launched on Jianmu-1 and Jianmu-2.
After subsequent technologies are verified and mature, these technologies will be applied to larger-scale space vehicles.
And when the technology of this type of spacecraft matures, this kind of spacecraft will have huge advantages in the detection and flight of alien planets.
Of course, for Wu Hao and others, whether it is a large space vehicle or a small space vehicle, if it is successfully developed, it will definitely write history.
At this time, Zhou Xiangming, who came out of the on-site cordon, walked towards Wu Hao and the others and said with joy on his face: "Judging from the preliminary inspection at the scene, the landing of the first-stage rocket body was very successful. The first-stage rocket body has been preserved." good.
Next, we will transport the first-stage body of the rocket to the factory and conduct a careful inspection. After confirming that there are no problems, the first-stage body of the rocket will be refilled with parachutes and fueled. Then perform a second launch. "
"Great, everyone's hard work has finally paid off." Let's announce it to everyone, they are also waiting for it. Wu Hao said with a smile.
Yu Chengwu nodded when he heard this, and then walked towards the reporters.
At this moment, the Internet is already dominated by news about this rocket. Basically all domestic media reported the incident on their front pages.
A group of aerospace and military enthusiasts are very excited, and many people have even begun to ask if there are related models.
For more ordinary people, the multiple firsts and honors achieved by this launch also make these ordinary people very happy.
After all, such a promising project, in such a form and environment, is really valuable and worthy of praise.
