Got an idea? The old horse's eyes lit up for a moment, and he said excitedly.

"Hehe, there are some immature ideas, but ah, these are just ideas, and how to achieve them depends on the opinions and choices of the relevant teams." Wu Hao said with a smile.

Seeing that Wu Hao was reluctant to say more in this regard, Lao Ma nodded and did not ask any more. After all, no one will confide in such a major core project at will, and it is in front of so many people.

As for Brother Xiaoma, at this time, he saw the stitches and threw out another question: "When will the second-stage rocket body be successfully recovered, it will be too good." ”

Wu Hao smiled and said: "The second-stage rocket probably stands about twenty to twenty-five percent of the cost of the entire rocket, and the proportion is not high.

Moreover, the recovery of the second-stage rocket is more difficult, because the second-stage rocket has already rushed out of the atmosphere, and it is no less difficult than the current manned spacecraft to re-enter the atmosphere and achieve a safe landing.

So for all these reasons, no company has implemented this technology yet. However, many similar ideas and plans have been put forward, and many of them have constructive opinions and ideas.

For example, some experts have put forward an eye-catching plan, referring to Musk's interstellar spaceship structure scheme. The second-stage rocket body of the rocket and the fairing of the payload compartment are joined together to design a reusable aircraft, or arrow body, to perform the task.

The expert's plan is to design the second-stage rocket body and payload chamber fairing to resemble a space shuttle or X37B-like vehicle.

The vehicle is sent to a critical space altitude by relying on the retractable first-stage rocket body, and then the aircraft engine is started, so as to fly to the target orbit and fly in orbit.

During the orbital flight, it can perform a variety of tasks, which are almost the same as those of the space shuttle, such as releasing satellites from the pilot's payload compartment, and so on.

After completing its in-orbit mission, the vehicle will re-enter the atmosphere, glide with its wings, and then open its landing gear and land on a predetermined runway.

In this way, the entire rocket section can be reused, the cost will be further reduced, and the tasks that can be performed will be very diverse. ”

"A very good idea, if realized, could become an important means of transportation for human beings to go to space in the future, and its significance is almost equivalent to the invention of passenger planes." The old horse exclaimed.

As for Brother Xiaoma, 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 underway." ”

"Oh, what's the problem?" Lao Ma couldn't help asking.

"It's a big problem, it's a whole new way of structuring, and there's a whole range of problems that need to be solved." Wu Hao said with a helpless expression.

Although he said so, in fact the project has already been launched, and the project is codenamed "Space Bus".

Judging from the project codename, the name "Space Bus" is to hope that this aircraft can be like a bus, sending more people and payloads into space, and becoming a bridge and ladder between space and the earth.

Although the project was approved, as Wu Hao said, there were many difficulties and problems encountered and there were big differences.

Some technical experts believe that we should focus on the rocket body of the Jianmu No. 1 or Jianmu No. 2 first-stage rocket, which we have matured at present, 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 there is relatively little investment in R&D. As for the shortcomings, it is naturally obvious, whether it is Jianmu No. 1 or No. 2, the carrying capacity is very limited, and it is difficult to transport a super-heavy space vehicle into the sky, let alone what kind of payload.

Moreover, the diameter of the rocket body is limited, and the volume of the aircraft that can be carried is also very limited, so the use of this type of aircraft is very limited.

Therefore, some experts believe that we can not be limited to our own rockets, but can design and build 'space buses' that can be carried on other rockets.

For example, the Chang-5 rocket, which has gradually matured, has a large enough diameter of the first-stage rocket body and a booster to be able to transport heavier loads. Based on this, the project team could develop and build a flying machine about the size of a real bus. In this way, whether it is carrying goods or carrying people, the use is very obvious.

This plan is naturally very good, but there are also shortcomings, first of all, R&D investment, such a large space vehicle, how much its R&D cost, this no one can estimate.

The second is the technical difficulty, whether the load or the volume is not a large number, the difficulty will increase exponentially.

So the expert is worried that it is too risky to invest in such a huge project at once.

In the end, after heated discussions and comprehensive opinions, Wu Hao finally made a decision to invest in the research and development of small and medium-sized space vehicles that can be launched on Jianmu 1 and 2.

Once subsequent technologies have been validated and matured, they can be applied to larger-scale spacecraft.

Moreover, after the technology of this kind of space vehicle matures in the future, this kind of space vehicle has huge advantages in the exploration and flight of alien planets.

Of course, for Wu Hao and them, whether it is a large space vehicle or a small space vehicle, if it is successfully developed, it will inevitably write history.

At this time, Zhou Xiangming, who came out of the on-site cordon, walked over to Wu Hao and said with a happy face: "Judging from the preliminary inspection at the current scene, the landing of the first-stage rocket body is very fruitful, and the first-stage rocket body is well preserved.

In the next step, we will transport the first stage of the rocket to the factory, and then conduct a careful inspection, after confirming that there is no problem, the first stage of the rocket will be refilled with parachutes, refueled, and then carried out a second launch. ”

"Great, everyone's hard work has not been in vain." Let's announce it to everyone, they are also waiting. Wu Hao said with a smile.

Yu Chengwu nodded when he heard this, and then walked towards the group of reporters.

And at this moment, the Internet has been dominated by the news of this rocket. Basically all the domestic media reported on 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 any related models.

And for more ordinary people, the many firsts and honors of this launch also made these ordinary people very happy.

After all, such a competitive project, in such a form and environment, is really commendable and commendable.
