Chapter 3085 will open a new era of human exploration of space
"So how to save fuel and increase transportation load has become the focus of our scientists' research, and everyone has proposed various solutions.
Among them is the parachute deceleration technology used on our traditional spacecraft and our Jianmu-2A launch vehicle.
The parachute is used to decelerate the aircraft when it returns to the atmosphere and lands, thereby greatly saving the fuel consumption of the engine for reverse thrust deceleration. In this way, a large amount of fuel costs can be saved and the transport load of the aircraft can be increased.
But this will also bring about a new problem, that is, this kind of aircraft is generally relatively heavy. If a parachute is used, a very huge parachute bag is required, so there are higher requirements for the material strength of the parachute. In addition,
In addition, this kind of parachute bag itself will also occupy a certain amount of load space including transportation load, so it is also a waste.
Finally, if you use a parachute to land, the airflow will have a huge impact on the landing accuracy, so the aircraft cannot land accurately on the preset landing site.
So in the end we set our sights on the space shuttle. During the process of returning to the atmosphere and landing, the space shuttle can glide in the atmosphere relying on the lift generated by its wings, thereby greatly reducing fuel consumption and thus saving money.
Lower costs.
Moreover, the landing point of the space shuttle only requires one runway, so there is no search and recovery process, which can greatly reduce the work and cost of search and recovery.
Then there is the fact that the space shuttle has relatively strong maneuverability and can achieve rapid and continuous launches, unlike other methods that require a long time to prepare.
Finally, because there are successful cases of the space shuttle that can be used for reference, the related development difficulty can be reduced.
So we determined the main development direction, which was to develop this multi-purpose orbiter into a new space-to-space shuttle vehicle, or a space shuttle.
However, the word "space shuttle" is relatively sensitive, so we try to avoid using it to avoid causing unnecessary controversy and attention."
Indeed, after hearing this, Qin Xinghe nodded in agreement. The word space shuttle is indeed very sensitive and can easily attract the attention of others. After all, for a long time, the space shuttle has been a symbol of Laomi's space hegemony. So if Wu
If Hao and others use this word, it will easily cause other people to have unnecessary associations, and there may even be some people who are hostile to us and people with good intentions who will use it to hype it up.
Anyway, it’s just a name. It can be called anything. It can be a space shuttle or a multi-purpose orbiter. It doesn’t affect anything.
After explaining this point, Wu Hao continued: "Although the development cost and unit production cost of this multi-purpose orbiter are more expensive than ordinary launch vehicles and manned cargo spacecraft, the advantage is that it can be reused.
Therefore, if the cost is evenly amortized each time, it can be reduced to a very low level.
In addition, compared with manned spacecraft, this multi-purpose orbiter is simple to deploy and launch, flexible and maneuverable. It can perform various uplink or downlink missions, and can also perform some special tasks in space orbit.
So from this point of view, its application scenarios are much wider than the current manned and cargo spacecraft. It can be said to be the technological development direction and form of future manned or cargo spacecraft.
Moreover, using this multi-purpose orbiter to carry personnel can provide personnel with a more comfortable riding experience. First of all, the cabin space is relatively large, so members will ride more comfortably and not be crowded.
Secondly, because the space inside the cabin is relatively large, the facilities and equipment are relatively complete. For example, toilets that are not available in traditional manned spacecraft can be installed to solve the urgent needs of astronauts.
Whether it is transporting people or cargo, this multi-purpose orbiter has a huge internal space that is unmatched by ordinary manned and cargo spacecraft. Its number of passengers is twice or even three times that of new manned and cargo spacecraft.
times.
It can carry more than fifteen or even twenty people into space at one time, greatly improving its personnel carrying capacity.
The cargo carrying capacity can also increase from six to seven tons, seven to eight tons, to more than ten tons, and it can also transport some large-sized cargo, which is difficult for traditional cargo spacecraft to match.
Finally, during the landing phase, the entire multi-purpose orbiter adopts a gliding landing method. This method is like the process of landing an airplane. Compared with the landing method of a manned spacecraft, especially the final buffer landing stage.
, much more comfortable.”
After hearing Wu Hao's introduction, Qin Xinghe's heart was also ignited by the passion in Wu Hao's words. He saw his temper rising and said: "You are right, this kind of reusable shuttle between heaven and earth can be used multiple times.
Manned and cargo aircraft are definitely the development direction of future aerospace technology. Your ability to foresight and seize the opportunity is very worthy of recognition.
Once this multi-purpose orbiter is successfully developed and launched for the first time, it will undoubtedly open a new era of human exploration of space and bring human space activities into a new era.
So now I am more curious about the development progress of your multi-purpose orbiter, and when will it be ready for its first flight?"
Hearing this question, Wu Hao and Zhang Jun, who listened carefully, couldn't help laughing.
Wu Hao replied with a smile: "It's still early. You know the technical difficulty of developing such a multi-purpose orbiter. How could it be successfully developed so quickly?"
Qin Xinghe smiled and joked: "You can't tell. Maybe it takes a long time for others, but it can't be normalized for you. You don't even think about how many miracles you have created, and there is still less than this."
A little?"
Forehead……
Wu Hao and Zhang Jun looked at each other and laughed heartily.
Wu Hao said with a smile: "That cannot violate the laws of development of things. Currently, this multi-purpose orbiter is in the process of development. We have passed the research work on the overall design and technical theory, and then we will start specific development.
Already working.
Because the technical difficulty is relatively high, the entire development work will definitely take time. We can’t say exactly when progress will be made.
If everything goes well, it will probably be very fast, but if the technical problems cannot be overcome, then the development progress and time will have to be extended indefinitely.
However, we are not in a hurry for this project. We are taking our time and advancing steadily bit by bit. After all, at this stage, our need for it is not so urgent. At present, our Walker manned cargo spacecraft can meet our needs.
