Face this problem and face the eyes of everyone. Wu Hao smiled and nodded and said, "Of course, as long as everyone is willing to listen."
This manned program has no specific technology, and there is nothing to keep secret. And with technology like this, even if it is announced, it is not that simple for other countries and companies to imitate and plagiarize it. Just like a launch vehicle, it is nothing more than using reverse thrust to launch the payload into the sky. However, so far, there are only a handful of countries and companies that can independently develop launch vehicles and successfully launch them.
Another example is the mushroom bomb. Its principle is very simple. There is a lot of information about this on the Internet, which is very detailed. But not everyone can create this kind of thing, and it is currently only in the hands of a few countries.
"Our technical plan for manned moon landing is divided into three parts. The first part is the first part." Wu Hao introduced it to everyone based on the model displayed on the platform.
“The first thing we have to do is to send people to space. This is the first step of the ladder plan. Only after sending people safely to space can we consider the next steps of going to the moon and landing on the moon.
In this part, we also make full use of our current relatively mature technology, which is our Walker manned spacecraft. Using it, we can send passengers into space.
Because it uses existing technology and most of the launch vehicle can be recycled and reused, even the Walker's manned capsule, which is the return capsule, can be reused, so we can control the manned cost at this stage to a lower level, resulting in substantial cost savings. "
At this point in the explanation, Wu Hao glanced at everyone, and then continued: "The next step is the second part, which is the orbital transfer process. There are 380,000 kilometers from the earth to the moon, and multiple orbit changes are needed to reach it. .
Normally, this transfer process is carried out by the lunar orbiter. And this time, we specially designed a transfer spacecraft for this purpose.
It is also divided into two parts, one is the manned living cabin and the other is the orbital service module. This transfer spacecraft travels between the Earth and the Moon's transfer orbits, transporting people and materials. Therefore, our scientific researchers gave it a nice name 'Space Bus'.
The entire space bus transfer spacecraft is only responsible for transporting materials and personnel between the Earth and the Moon, so it can perform long-term round-trip missions between the Earth and the Moon. Normally, such a transfer spacecraft can be used in space for five to ten years, or even longer. This can save a lot of personnel and material transportation costs.
It is also called a 'permanent' transfer spacecraft, so we can expand the volume appropriately to increase the volume of the manned living compartment. In this way, on the one hand, it can accommodate more passengers, thereby further reducing costs. On the other hand, it can also provide passengers with a more comfortable riding environment experience.
Rather than huddled in a manned cabin of only a few square meters or more for a long time, this experience is very bad. "
What about the permanent transfer of the spacecraft and fuel supply? Some experts asked.
Wu Hao answered with a smile: "Simple, replenish and replenish fuel materials during the transportation and docking process of personnel and materials."
Seeing that the expert did not continue to ask questions, Wu Hao continued: "During this process, passengers and related materials were transferred from the Walker manned spacecraft to the 'Space Bus' transfer spacecraft. During the docking process, they will also Fill and replenish the 'Space Bus' transfer spacecraft with fuel, oxygen, water, food and other supplies.
Immediately afterwards, the 'Space Bus' transfer spacecraft separated from the Walker manned spacecraft, began to ignite and start the engine, began to enter the Earth-moon transfer orbit, and flew to the moon.
After arriving at the moon and entering the lunar orbit, the lunar lander rising from the moon will dock with the 'Space Bus' transfer spacecraft, and personnel and materials will be transferred to the lunar lander.
In this process, the personnel and materials in the lunar lander that rose from the moon will also enter the 'Space Bus' transfer spacecraft one after another to complete the rotation.
Immediately, the lunar lander separated from the 'Space Bus' transfer spacecraft, carried the newly arrived passengers, and then landed on the landing field of the scientific research station on the moon, and then stationed at the scientific research station.
As for the 'Space Bus' transfer spacecraft, the people and materials that came up from the moon began to fly to the earth. After reaching the Earth's orbit, it will immediately dock with the Walker manned spacecraft waiting there to transfer the personnel and materials in the 'space bus' transfer spacecraft.
After the transfer was completed, the Walker manned spacecraft detached and began to return to Earth carrying these people and materials. As for the 'Space Bus' transfer spacecraft, it changes its orbit and starts flying around the earth in a low energy consumption state, waiting for the next mission. "
After hearing Wu Hao's introduction, these experts couldn't help but nod their heads. It has to be said that this is a very complete and very feasible design plan for manned lunar landing. Among this plan, the most amazing or praiseworthy thing is naturally that Wu Hao and the others have taken their stinginess to the extreme and can really control the cost to the minimum.
One expert couldn't help but ask: "Is this lunar lander also reusable?"
Wu Hao smiled and nodded and replied: "Yes, it can also be reused. Its main function and function is to transport personnel and materials for taking off and landing on the moon.
The entire lunar lander adopts a modular design and can be equipped with different functional modules according to different mission requirements.
In addition, a major advantage of this design is that it facilitates maintenance and replacement of parts, thereby extending its working life. "
"Taking off and landing on the moon requires a lot of fuel. How to obtain this fuel?" the expert asked.
Wu Hao stretched out two fingers and replied with a smile: "Two ways, one still relies on stepped fuel and material supplies between spacecraft. When docking with the 'Space Bus' transfer spacecraft, take the opportunity to refuel and material supplies.
Another way is to use water and related mineral resources on the moon to produce oxygen, hydrogen, and methane to serve as the main fuel for the lunar lander. In this way, costs can be reduced. "
Well, after hearing this, many experts had a wry smile on their faces and started to complain. Sure enough, in terms of cost control, Wu Hao and the others really did everything they could, taking their stingy skills to the extreme.
However, I have to say that this relay-style manned moon landing plan is very amazing. If it can be implemented, it will be able to greatly reduce the transportation cost of manned lunar landings, thus laying the foundation for large-scale lunar landings and utilization of the moon.
