"How low can that go?" Wu Tong was the one who asked, and she was obviously very interested in this question.

Hearing Wu Tong's question, Wu Hao said with a smile: "In an ideal situation in the future, the price of our space ticket will probably be more expensive than our international flight price, and it may cost about 100,000 US dollars."

Wouldn't that be 600,000 to 700,000 yuan? Can ordinary families really afford it? Wu Tong asked involuntarily.

In this regard, Wu Hao smiled and said: "If you can't bear it, don't go there. This thing is not a necessity. To put it bluntly, it is still a tourist item, and everyone should naturally do what they can."

Wu Jianhua nodded when he heard the words: "The price is not expensive. For example, some of our expensive group tours cost hundreds of thousands or hundreds of thousands of dollars, and a round-the-world cruise ticket costs tens of thousands of dollars.

If the price can really be reduced to such a low level, then space travel will definitely be popular in the future, and no one can resist the temptation to travel around in space at a low price. "

Speaking of this, Wu Jianhua couldn't help but look suspiciously at Wu Hao and asked: "However, can this price really be won?"

Facing his father's questioning gaze, Wu Hao nodded with a smile and replied: "Of course the current space manned technology cannot be achieved, but the next generation manned technology can be realized. Its structure and principle are probably similar to Musk's. The starship is about the same.

In fact, we are also carrying out research work in this area, but our starship, or space shuttle, is still very different from Musk's starship. "

Hearing what Wu Hao said, everyone present became interested. They also wanted to know what Wu Hao's future manned aircraft would look like.

Seeing everyone's anticipation, Wu Hao introduced with a smile: "In fact, our next-generation manned space shuttle is expected to be called a starship, a spaceship, and it might as well be called a space shuttle."

Isn't the space shuttle eliminated? Wu Jianhua couldn't help asking.

Wu Hao smiled and said: "In fact, the space shuttle is a very ideal space shuttle vehicle. The reason why it was eliminated is because of its frequent accidents and poor reliability, and because of its development cost and operating cost. , The success or failure of the launch is relatively high. That's why the United States chose to retire and give up.

But we must also note that in recent years, small sounding shuttles similar to the space shuttle, such as Laomi's X37B, our Shenlong aerospace vehicle and so on.

The appearance of these aircraft is very similar to the space shuttle, and the principle of launching and returning is the same. It is first launched by a rocket, then enters space and circles in orbit, and then glides from space back to the ground in exactly the same way as the space shuttle.

As for our next-generation manned space shuttle, its structure is similar to that of Musk's starship. It is divided into two stages. The first-stage rocket is a core-stage reusable launch vehicle composed of dozens of high-thrust rocket engines. It is the same as the core stage part of our returnable launch vehicle at present, and it can realize return landing and reuse.

In this way, its launch cost can be greatly reduced. It is expected that such a core first-stage rocket will be used more than 20 times. Then the development cost can be allocated to each launch, and the launch cost will be greatly reduced.

As for the second-level part, it is very different from the starship. The second-level part of the starship is actually a rocket, or a manned rocket. And our secondary part is actually a space shuttle.

In the past, space shuttles were launched with bundled rockets and huge fuel tanks, but now, we only need to install them on the rocket, which has a lot to do with the development of technology and materials.

Of course, if necessary, retractable boosters can be bundled around the first-stage rocket, and different numbers of boosters can be bundled according to the weight, which can be two or four.

The core first-stage rocket and booster will transport the second-stage manned shuttle vehicle to an altitude of tens of kilometers with its huge thrust. When the space shuttle is ignited, it will push itself out of the earth with its strong thrust and reach low earth orbit.

The crewed shuttle will orbit space for as long as the mission requires. Then return to Earth.

It will glide and land on the dense atmosphere like a float, and then use the lift of the wings to slowly glide to the airport runway and land. "

How many people can such a space shuttle carry? Wu Jianhua then asked.

Wu Hao replied: "Depending on the mission, the number of people it can carry is also different. According to our current design plan, the number of people carried by such a space-to-earth manned aircraft is about 25 to 30 people. "

"so much?"

"so little?"

Two voices popped out at the same time. Wu Jianhua said a lot, UU Reading www.uukanshu.com As someone who has a certain understanding of aerospace, he naturally knows what this number represents.

At present, the number of people carried by the traditional first-generation manned spacecraft is about three to four, while the number of people carried by the new generation of manned spacecraft is about six to seven, and the maximum number may be seven to eight. Basically at this level.

And the space-to-earth manned spacecraft that Wu Hao talked about can actually carry 25 to 30 people. This kind of manned capacity is more than four times that of the new generation of manned spaceships. This is definitely an excellent result.

Wu Tong was the one who said less, and she obviously felt that the amount Wu Hao said was a bit small. In her opinion, since they are all space shuttles, why can't they carry more people, just like a plane carrying more than a hundred people?

In this regard, Wu Hao smiled and said: "At present, this manned capacity is relatively appropriate. If it is too small, it will not be cost-effective, and the gap with the new generation of manned spaceships will not be widened. If the number is too large, The corresponding costs will also increase, and the economic benefits will deteriorate, so this should be regarded as a relatively appropriate range.”

Hearing Wu Hao's words, everyone present nodded their heads.

At this time, Zhang Xiaoman, who had been silent all this time, asked, "Then when will such a manned aircraft be successfully developed?"

hehe…

Hearing this question, Wu Hao smiled and shook his head in the face of everyone's expectant eyes: "I don't know yet, it depends on the follow-up development and actual needs.

It is impossible for us to develop such a space-to-earth shuttle manned aircraft just for space travel, which is unrealistic. Any of our projects are closely related to our actual development needs, and we will not start blindly.

Of course, I believe that with the development of the global aerospace industry, this day will not be too late. "
