Tower Defense Strategy

The mobilization ability of country C is really good.

After considering various factors, it was decided to simplify the launch process of the rocket that transports construction materials such as brick walls and bulletproof cloth.

How simple is it?

The rocket is transported from the railway line to the launch center, and it is assembled while being inspected. Once the rocket is installed, it will go through the machine inspection and wait for the launch window.

The old model rocket is used, and the production time for mass production is limited, because many parts have been built and placed there long ago in order to relieve stress. There are already cases in the transportation link, just copy them, and there is no need to go through multi-department meetings to communicate.

In six days, after the quantitative rocket plan came out, it took only six days. The first batch of two 200-ton rockets stood on two launch sites thousands of kilometers apart, waiting to be launched.

The follow-up will be even faster, because manufacturers no longer need to open a mold for a part and have a headache, just like the production of train cars, and mass production of all parts!

In order to speed up the process, a group of missile-building technicians have also been hired to provide production guidance to some private enterprises in order to provide some components more efficiently.

On the eighth day, the three rockets took advantage of the launch window and were launched into the sky within a few hours.

Scholars at the octopus base also specially found octopus and showed him a video of cargo docking.

To be honest, Octopus has some questions about this. I don’t know where to find historical references on the game reset party. Did the ancients really have this efficiency? If it is a real historical parameter, it is no wonder that it has been so long from rocket to automation, and there is not much need for low-level automation.

Rockets and missiles are indeed the same type of technology, but rockets and missiles are also completely different things in the world of money. The missile is just a simplified and minimalist version of the rocket.

The rockets were mass-produced in a few days. If you follow this pace, the monsters can also be hit!

The C National Academy of Sciences and the Aerospace Department were also in pain and happiness at this time.

The happy part is the first batch of successful launches after simplifying the process, the first time in decades of work that saw multiple launch sites erect rockets at the same time, and some are proud of national power.

The painful part is that some burn money too fast, some feel that the timing is not good, and some astronauts are not enough.

I won't talk about burning money.

Some people feel that the timing is not good, because a few months ago, when the monsters just showed signs and there was no confirmation that there would be little monsters, there were two foreigners among the last group of astronauts who changed their shifts.

One is Domkakovsky from country R, ​​a forty-year-old senior astronaut who has boarded the former R-country Union space station and the International Space Station, and has many experience dealing with space station failures.

One is a young scientist from West Central Continent. Frederick Albert, a thirty-two-year-old botanist, was selected because he had the best vital signs and mental health among a group of foreign scientists. Multi-national cooperative space crop research project.

The above didn’t think it was necessary to keep it confidential. After the mass production plan was launched, the communication rights of the two foreign astronauts were not restricted. It is just the people of the Aerospace System and the Academy of Sciences. What if country A takes a space fighter to hit us?

If there are not enough astronauts, the headache is even worse.

A few days ago, I said I wanted astronauts, and suddenly I sent a dozen tons of building materials up.

Brick wall, 18.5 kilograms per square meter, in order to ensure that the welding workload does not increase indefinitely, the inner diameter of the rocket fairing is used as much as possible, which is just over three meters.

The largest plate, including bending, is only 12 square meters. In a dozen tons of building materials, there are more than 120 large and small plates, and the total length of the weld is more than 600 meters.

Welding a six-hundred-meter weld on the surface is not a trivial task. If you put it in space, you will kill the astronauts.

That's it, I haven't even counted how much trouble and danger the few eight or nine square meters and those with chamfered plates and hundreds of kilograms of welding equipment will bring to astronauts in the process of space displacement.

In fact, some of the issues have been raised a few days ago, just because the astronauts are in the sky, and the communication is still unclear.

Now the first batch of building materials has been delivered. Several astronauts went out of the cabin and worked a circle. When they came back, they did nothing. They received inquiries from multiple departments and manufacturers to see what the difficulties were and how to solve them.

In the training of astronauts, hands-on ability is very important.

For human beings who are initially exploring outer space, many problems cannot be imagined on the surface. At the same time, for reasons including mental health, astronauts will be allowed to bring some personal belongings to the sky, sometimes with the help of a large group of experts. , These personal items, plus some unimportant things removed from the space station, can all become key props to solve the problem.

Soon everyone gathered and solved the main problems.

First, the astronauts can't wear spacesuits for a long time, and toss about such heavy things outside the cabin. The fuel consumption of oxygen and RCS system is higher than expected.

In response to this, in a short period of time can only increase the distribution of oxygen powder, compressed air, high-calorie food, and RCS fuel to allow the astronauts to overcome the difficulties.

After that, a kind of professional out-of-vehicle construction equipment, even a small spacecraft with a robotic arm, will inevitably be needed. Most of the academy staff prefer the latter, while the aerospace department prefers the former. Part of the reason is that the aerospace department pays more attention to safety rather than efficiency. In addition, the small engineering spacecraft does not just say a word, how to do the docking system with the main building, what value should be taken for personnel vision, pressure maintenance, etc., etc. , They have never been encountered before and need to be solved from scratch.

Second, safety.

The term single security is very broad, and it also refers to several aspects here.

The existing space station has power and can be pushed every time to maintain orbital height, while the new space station is not equipped with power yet. Tie the two with a rope, threatening the safety of the existing space station. Astronauts are very worried and have to observe the status of the new space station every once in a while; don't tether it, the distance between the two will definitely get farther and farther.

There is also what the ground personnel mentioned before, what if there is a madman who uses space weapons or anti-satellite weapons to fight?

In response to the previous problem, an adsorption-type manual propulsion unit is already on the ground to adjust the attitude of the new space station; in the future, a special plasma propulsion unit will be used.

Plasma propulsion is not a new concept. Strictly speaking, the flame itself is also plasma, but now everyone accepts the concept of "accelerating electrons and ions with electricity to gain thrust".

The plasma thruster manufactured by the earth ball technology has basically no thrust, and can only obtain a small speed change through a long time of opening.

However, the existing plasma propulsion is actually mainly limited by the amount of electricity, and the hundreds of kilowatts of power on the satellite can accelerate several particles.

The new space station will have a huge difference in this respect. It was built to learn "zero-gravity vacuum processing". After that, the power generation capacity will rise to several thousand kilowatts or even higher, which is predictable. The acceleration capability of the plasma thruster You can also get a qualitative improvement.

In short, it is possible to prevent the new type of space station from falling into the atmosphere while consuming as little material as possible.

It's more difficult to guard against being attacked.

It's easy to install a laser weapon, and it's also better to use in space.

But as the monsters frequently commit crimes, missiles will fly over the space station to attack the monsters at any time, and some of the ballistic heights are even higher than the space station.

So you have to get a set of radar, and let the new space station have the ability of ballistic analysis. A few tons of equipment is fine. The problem is that the radar is a thing of high power, but it is still a problem of electricity.

There is another way, to upgrade the orbit, build the new-type space station to a certain extent, and upgrade it to mid-orbit. If it is not enough, then upgrade again.

But the safety of the ascent is safe, and it will bring new problems. How can the ground materials go up?

A rocket that can send ten tons to low orbit, and to mid-orbit, can only send two or three tons of cargo, and the number of people going back and forth is almost...

Anyway, it’s a bit difficult for a while. You can only ask the diplomatic department and the media to help speak first, and don’t let the actions here trigger excessive hostility from others~www.wuxiaspot.com~The space station, the academy of sciences, and the space department are still discussing. Someone here also showed the octopus some of the summarized questions.

Octopus frowned and finished reading, feeling that it was not easy for humans to get out of the home planet. Every day is always more difficult than the day before, and even more difficult.

After saying "I got it", I went offline again, and when I came up a few hours later, there were two more documents.

One document is "Deep Space Engineer", which is a rechargeable automatic robot designed for the welding of main materials of several space stations and the deployment of exterior coatings.

The earth ball has no ability to automate, nor other types of main materials. Octopus even helped to mark out the key points. Its predecessor was a remote control device for welding brick walls, and it did not have the ability to deploy coatings, but because In this way, it can be directly modified with the welding equipment that the earth ball is now in space. As for the material is not good enough, the individual should be bigger.

The other is the early plasma thruster principle and the plasma fuel synthesis process. Except for the use of specialized plasma fuel, it is not much different from the existing technology of Tuqiu. It gives up some of the advantages of the power-down thruster, and obtains a powerful thrust to adjust the height of the space station in a short period of time (a few hours), and at the same time saves a little power.
