Faced with this question and everyone's gaze, Wu Hao smiled and nodded and said, "Of course, as long as everyone is willing to listen."
There is no specific technology for this manned program. There is nothing to keep secret. And even if the technology in this area is revealed, it is not that simple for other countries and companies to imitate and plagiarize it. It is just like a launch vehicle.
It just uses 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. However, not everyone can create this kind of thing, and it is currently only controlled by a few countries.
in hand.
"Our technical plan for manned lunar 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 landing orbiter. But 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 the transportation of 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
Over a long period of time, 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 and increase the volume of the manned living compartment. In this way, on the one hand, more passengers can be accommodated, 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 with only a few square meters or more for a long time, this experience is very bad."
What to do if the spacecraft is permanently transferred and replenished with fuel? Some experts asked.
Wu Hao answered with a smile: "Simple, replenishing and replenishing fuel and materials during the transportation and docking 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 supply fuel, oxygen, water, food and other materials to the 'Space Bus' transfer spacecraft.
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.
During 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 site 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 orbit around the earth, it immediately docked with the Walker manned spacecraft waiting there, thus
Transfer the personnel and materials inside the 'space bus' transfer spacecraft.
After the transfer was completed, the Walker manned spacecraft detached and began to carry these people and materials back to Earth. As for the 'Space Bus' transfer spacecraft, it changed its orbit and began to fly around the Earth in a low-energy state, waiting for the next
A mission.”
After hearing Wu Hao's introduction, these experts couldn't help but nod their heads. It must be said that this is a very complete and very feasible design plan for manned lunar landing. And here
Among the plans, the most surprising or praiseworthy thing is naturally that Wu Hao and the others took their stinginess to the extreme and were able to really control the cost to a 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 role is to undertake the transportation of 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, thus 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 the stepped fuel and material supply 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, the cost can be reduced.
compression."
Well, after hearing this, many experts showed a wry smile on their faces and complained repeatedly. 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, it has to be said that this relay-type manned lunar landing plan is very amazing. If it can be implemented, it will be able to greatly reduce the transportation cost of manned lunar landing, thus providing the basis for large-scale lunar landing.
