After hearing Wu Hao's introduction, many people present couldn't help but become 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 a sky-high price for these countries. Take Laomi's Keyhole satellite as an example. The cost of one of its "Keyhole-11" satellites is US$6.35 billion, which is more expensive than an aircraft carrier.
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.
So these people have always longed to have their own satellites, but have always been stagnant. Now when they learned that Haoyu Technology's satellites were very cheap and included launch, they realized that the opportunity had finally arrived. So one by one they quickly dispatched teams to the country and 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, spaceships, etc.
First 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 materials and personnel to the space station, undertaking the task of supplying materials and transporting personnel to the space station.
In the future, we will also actively increase opening up to the outside world and strengthen its application in the civilian field. If you are interested by then, you only need a little money to take this manned spacecraft and travel in space 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 into contact with and watched this kind of manned spacecraft return capsule at such a close distance, so these people were very interested.
Even General Yevgeny showed 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 reasons, Mao Xiong has been using the old and traditional Alliance manned spacecraft until now. 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 as to why such a private technology company could build this manned spacecraft, which even their country had not yet built, and successfully built it.
"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. There are more of them among the generation of manned spacecraft."
"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 Rashid said to Wu Hao after watching it carefully.
After hearing what General Rashid said, 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 Dragon spacecraft and even Alliance spacecraft.
The reason why it is similar to the Dragon spacecraft is because 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 reuse the return capsule, but a return capsule like this 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 period of time.
When a problem occurs with the launch vehicle underneath 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 side strips will ignite quickly, thereby pushing the entire return capsule away from the orbital service module and the rocket, avoiding the malfunctioning rocket, and pushing the return capsule into the airspace away from the rocket. Immediately, the landing system is activated, and the deceleration parachute on the return capsule will be opened, so that the return capsule is suspended and landed slowly, and the astronauts and passengers in the return capsule can also avoid danger safely.
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 will not be injured by the huge impact force.
And compared with traditional spacecraft that require instantaneous explosive 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 downwards. When it is one meter close to the ground, the speed is basically the same as the descending speed. That is to say, the descending speed is zero, so the landing speed is zero. There will not be too much impact, and the passengers inside will not feel uncomfortable due to the huge deceleration buffer force. "
