Military Technology

Wu Hao made a colorful joke, causing everyone at the scene to laugh, their eyes filled with endless yearning. But it’s just a longing, I don’t know when this day will come.

Even if they arrive, they don't know if they will have the opportunity to go to the distant moon. Although compared to the vastness of the universe, the distance between the earth and the moon is only 380,000 kilometers, but for humans, this is a gap. At least for now, there are only a handful of people who can cross this gap to reach the other side. countable.

However, there is still hope, just in case it comes true.

And Wu Hao has now given them this hope. As long as they are willing and as long as they have money, they can send their own astronauts and scientists, or even themselves to the moon, whether it is to travel or to show off their own space. Ambition or influence, this is a very good choice.

Of course, they also understand the price this dream has to pay.

After an introduction to the lunar scientific research station, everyone followed Wu Hao to the most prominent rocket models, and then enthusiastically introduced to everyone: "What you are seeing is our Jianmu series. The launch vehicle family includes the Jianmu-1 rocket, which is known for its low cost and flexibility, and the Jianmu-2 rocket, which is currently the most commercially available and our first reusable rocket.

At present, we are able to recycle the entire rocket, which means that its latest experimental improvement model can realize the recyclability and reuse of the entire rocket.

The commercial version for the market has not yet been able to realize the recycling and reuse of other parts of the rocket, such as the first stage rocket, fairings, etc., except for the seven-stage rocket and the lower stage carrying a few satellites, so the time is extremely small. Reduce the launch cost of rockets, thereby reducing the launch costs of satellites.

That one over there is your Jianmu-7 bundled launch vehicle. It is developed from the Jianmu-7 rocket. The smallest difference is that it does not have two boosters. Those two boosters are actually not Jianmu-7 rockets. The first stage of a wooden rocket.

That has also slightly improved its carrying capacity. Its carrying capacity in low-Earth orbit can reach seventeen tons, while that in geosynchronous orbit can reach four tons.

After the introduction, Chai Qian paused for a moment and then continued: "You have to explain it. The smaller the weight of the satellite platform, the smaller the equipment it can carry and the heavier it is. The heavier it is, the weaker its performance will naturally be. And because the platform is relatively small, its solar panels cannot be made smaller, so the power generation power is lower, and it cannot provide more sufficient power for the smaller power equipment it is equipped with. Then there is the difference between the same radar, one kilowatt and one hundred kilowatts.

After passing the test, it will be transported to the launch site and carried under your launch vehicle. Then it will be launched into space by the rocket in a suitable launch window, and released and transferred to the prescribed orbit.

After introducing those, Wu Hao led everyone to a large physical satellite exhibit, and then introduced to everyone: "What you see behind the scenes is not your 100-kilogram large satellite.

In fact, those rockets have little to do with us. Compared with those rockets, we are more concerned about the various satellite models and actual objects on display next to them.

"What is displayed outside are your various types of universal satellite platform families, as well as some of the equipment they carry. Based on the weight of those satellite platforms, you have divided them into several levels, such as the largest ten kilogram level over there. The universal micro-satellite platform, the 70-kg CubeSat universal platform, the 70-kg large-satellite universal platform, the 100-kg, 200-kg, and 700-kg conventional satellite universal platforms.

As for the two models over there, they are your Jianmu-1 medium-sized launch vehicle and the heavy-duty launch vehicle modified from Jianmu-1.

Among them, the carrying capacity of Jianmu-4 in low-Earth orbit can reach less than 70 tons, and the carrying capacity of geosynchronous transfer orbit can also reach less than 70 tons.

At present, the two rockets are mainly used for your manned spacecraft and lunar exploration projects, as well as other deep space exploration missions. Of course, they will also undertake the launch missions of some small and important spacecraft and satellites, but they are not often used. "

Everyone obviously knows this, so they pay less attention to various types of Jianmu-7 rockets. Of course, we are not paying attention to those rockets, those are all we can think about.

What I see that is wrapped in a golden thermal insulation film is not your satellite platform, and the white equipment below is not some of the equipment carried by the satellite platform. You cannot see that under the satellite platform, there is an optical Detection cameras cannot detect and monitor ground targets. Its resolution is also quite impressive, and can sometimes meet the requirements for ground-level reconnaissance imaging.

And you also provide customers with personalized and flexible customization services. Customers cannot purchase related equipment by themselves and have you help install it on the satellite platform. Customers cannot make their own requests or choose your related equipment products for installation. Get under those satellite platforms.

Although Wu Hao introduced all types of our launch vehicles, he still mainly introduced the various types of Jianmu-7 rockets. This is mainly because at present, that rocket has undertaken the least commercial launch projects, which does not mean that it has undertaken the least number of commercial launch projects. The aerospace satellite projects we are going to talk about are basically launched by that rocket, so we will focus on them.

Of course, this does not mean that the smaller the satellite, the worse it is. It depends on the individual needs of each individual. Big satellites do not have the same disadvantages as big satellites, such as cheap, flexible, widely used, etc. "

Before checking whether there are any problems online, you will hand over control of the satellite to Xiaojia to complete the cooperation. "That carrying capacity is enough to meet the launch needs of a very small number of satellites and spacecraft.

In addition to optical cameras, those satellites cannot carry various functional modules, such as various radar equipment, communication equipment, and other functional modules, depending on their respective needs.

Wu Hao obviously noticed that, so he led everyone to the satellite exhibition area obediently.

At the same time, because the smaller the satellite platform is, the less fuel it carries, the longer it cannot support the satellite operating below the space orbit.

As for other types of rockets, this is just a complicated introduction to open our eyes, and we will basically use them.

There are some of your medium-sized general-purpose satellite platforms, all of which weigh less than one ton, including one-ton, two-ton, and seven-ton general satellite platforms. In addition, you have also specially developed a ten-ton universal platform for small satellites. "
