Chapter 2740 The Satellite Dream of a Small Country
【Corrected version】
Hearing Wu Hao's introduction, many people present couldn't help but get excited. You must know that one of their main purposes for coming here this time is to discuss cooperation with Haoyu Technology and purchase launch-related military satellites for their country.
Although it has been more than seventy years, almost a century, since the world's first artificial satellite was launched, there are very few countries that have their own satellites.
It should be said that 70 to 80 percent of the countries in the world do not have their own satellites, let alone high-precision satellites specifically used in the military field.
Why? This is mainly because satellite and launch vehicle technology are cutting-edge technologies in every country and are kept strictly confidential. Moreover, whether the launch vehicle or the satellite itself is expensive, it can cost tens of millions or even hundreds of millions of dollars.
US dollars.
Not to mention those top military satellites, which are simply sky-high prices for these countries. Take Lao Mi's keyhole satellites as an example. The cost of one of its "Keyhole-11" satellites is US$6.35 billion.
An aircraft carrier is expensive.
Launching such a satellite would be a pain in the butt for even the wealthy Laomi, not to mention other countries, let alone these developing countries, whose annual military expenditures may not be as expensive as such a satellite.
Therefore, these people have always been eager to have their own satellites, but have always been deterred. Now when they learned that Haoyu Technology's satellites were very cheap and included launch, they realized that the opportunity had finally come. So they quickly dispatched teams one by one.
Came to the country, came to the northwest.
After having a general understanding of the entire base, Wu Hao led everyone to the last part of the exhibition hall, which was the achievement exhibition.
What is displayed here are the relevant achievements made by the Northwest Research Center over the years, such as drones, mechas, rockets, satellites, spacecraft, etc.
First of all, placed in the middle of the entire exhibition area is the return capsule of a manned spacecraft. From the rusty burn marks on it, we can see that this is a genuine product, not a replica.
"Is this a real manned spacecraft?" General Yevgeny from Mao Xiong asked as he looked at the return capsule of the new manned spacecraft in front of him.
Wu Hao smiled and nodded and introduced: "Yes, this is the actual return capsule of our Walker 2 manned experimental spacecraft. We also have a Walker 4 return capsule that has actually carried astronauts, but that one is in our Anxi
It is displayed in the Linghu Company Park.
At present, our Walker series of manned spacecraft have become one of the important vehicles for our country to enter and exit space to rotate space station materials and personnel, undertaking the task of supplying materials and personnel to and from the space station.
In the future, we will also actively increase our efforts to open up to the outside world and strengthen applications in the civilian field. If you are interested, you will only need a little money to travel in space on this manned spacecraft for a few days."
Hearing what Wu Hao said, everyone present couldn't help but become interested and looked at the return capsule carefully. Except for General Yevgeny from Russia, the other representatives in the crowd rarely came so close.
They have come into contact with and watched this manned spacecraft return capsule, so these people are very interested.
Even General Yevgeny has shown a strong interest in this return capsule. Although Mao Xiong has proposed his own design concept for a new generation of manned spacecraft, due to economic strength, Mao Xiong has not been able to use Mao Xiong until now.
They have been using the old and traditional Alliance manned spacecraft. So for them, they also very much hope to have a new generation of manned spacecraft.
So for General Yevgeny, he was naturally very interested in this return capsule. He was very curious about how such a private technology company could build this manned spacecraft that their country has not yet built.
came out, and it was successful.
"How many people can this return capsule carry?" General Yevgeny looked at it and then asked.
Wu Hao replied with a smile: "Normally, it can seat about seven people. If necessary, we can change the internal seat layout to expand the number of people to eight to nine. At present, our carrying capacity is considered to be at a new level.
One of the most numerous manned spacecrafts of the generation."
"Its appearance is very similar to that of the Dragon spacecraft. It has no fairing and only has a fairing hatch to protect the docking port." General Rushd looked at it carefully and said to Wu Hao.
After hearing General Rashid's words, Wu Hao did not shy away, but nodded very frankly, and then said with a smile: "Yes, during the design stage of the spacecraft, we referred to the design experience and experience of past spacecraft to a certain extent.
Technology, including the Dragon spacecraft and even the Alliance spacecraft.
The reason why it is similar to the Dragon spacecraft is that our strategy is similar, which is to reduce the operating cost of the spacecraft to the greatest extent. For example, our Walker series spacecraft can not only realize the reuse of the return capsule, but also can
The return capsule can be used more than ten times.
In this way, the cost of a single shipment can be greatly reduced and the transportation cost of astronauts can be reduced to a very low level.
Secondly, this design is safer. It does not require a fairing during the launch phase, nor does it require an escape tower used by traditional spacecraft. The escape device that ensures the safety of the Walker spacecraft is actually on the return capsule.
Well, these are the four ridges on the surface of the return capsule. Inside are small rocket engines that can generate powerful power in an extreme amount of time.
When there is a problem with the launch vehicle below the spacecraft during the launch phase, the spacecraft's intelligent control system will quickly activate the emergency escape system. The rocket engine under the raised part of the four sides will quickly ignite, thereby pushing the entire return capsule out of the orbit, the service module and the rocket.
, avoid the malfunctioning rocket, and push the return capsule into the airspace away from the rocket. Then the landing system starts, and the deceleration parachute on the return capsule will open, thus suspending the return capsule and landing slowly, and the astronauts and passengers in the return capsule can also
Safe escape.
In addition, the rocket engines behind these four prisms can also be started when the return capsule re-enters the atmosphere and returns to the ground for landing, providing powerful power to decelerate the return capsule to the greatest extent, thereby ensuring the safety of the return capsule landing.
Make sure that the passengers inside are not injured by the huge impact force.
And compared with traditional spacecraft that require an instant burst of deceleration and buffering, the rocket startup and deceleration process on our return capsule is very linear. It starts working from a few hundred meters, so the speed slowly decreases little by little.
By the time it is one meter close to the ground, the speed will basically be the same as the descent speed, which means that the descent speed is zero, so there will not be too much impact when landing, and the passengers inside will not be affected by the huge impact.
It feels uncomfortable to decelerate and buffer the force.”
