Tower Defense Strategy

"Tower Defense Strategy (!

After the Kunpeng Space Station completed the construction of the first-stage microgravity section, at the end of February, combined with the super kinetic energy storage rotor that had been waiting for several months, it was able to achieve 7×24 hours of stable power supply in the synchronous orbit.

The height of the orbit is emphasized here, because the higher the orbit, the lower the proportion of dark night. For example, the non-illuminated time of the synchronous orbit is just over an hour, and some of the higher latitudes have a shorter time when the light source is obscured by the host star.

The Kunpeng space station is located in a synchronous orbit. The night time is short. The weight of the 10 MW kinetic energy rotor is not particularly heavy. However, there is redundancy in the design. In the future, you can adjust the upper limit of the speed and sacrifice a little life to increase the energy storage limit. The final weight is still A special rocket is needed to send it.

The rotor and the new core section were separated from the rocket, the rotor was installed, and the rocket was thrown back. The amount of work done for this set was not small, and it was not completed until March 10.

Among them, the return of the rocket is also a standardized process recently completed. This type of heavy cargo rocket dedicated to the Kunpeng space station is made from the pile of engines and other parts left from the previous capture of the asteroid, and can drop 100 tons of cargo at a time. Synchronous orbit, of course, also consumes dozens of tons of fuel for round trips. There are three sets in total. The latest inspection shows that the three sets can be carried about 20 times together.

Along with the rotor, there is a new core section.

Excluding the main activity area of ​​centrifugal gravity simulation, the column section of the Kunpeng Space Station at this moment is divided into Death Scepter No. 2 Unit, 10 MW Energy Storage Rotor and Momentum Wheel Module, and the core cabin of the gravity simulation area (the slide enters and exits the gravity area) , Experimental column section and berth section.

The new core section is inserted between the second unit and the momentum wheel, and is mainly used for the subsequent expansion of power generation facilities, solar arrays, and head berths.

At this point in the construction progress, there is also a certain amount of material reserves. The second batch of personnel at the Kunpeng Space Station can already move in, or transfer from the future space station.

The seed space station plan for human civilization in Country A was also announced when the second batch of personnel went up to the sky in turn.

Its plan can be described in one word: creating wonders.

The so-called development steps are completely unexplained.

The superconductor of country A barely entered the stage of mass production. In terms of permanent magnets, it was only after the monster crisis that the permission to mine its own rare earths was opened, because the last permanent magnet company went to country C, and there is no upstream and downstream industry. The chain, the technological power is even more stretched.

On this basis, it is far away to launch its own electromagnetic orbital launcher.

Their solution is to pile up rocket engines.

When introducing rockets, the concept of characteristic specific impulse has been mentioned many times, which is the most important energy efficiency index of an engine.

The technical level remains unchanged, and the greater the characteristic specific impulse, the thrust will inevitably decrease.

The principle is simply explained. The higher the specific impulse, the higher the temperature of the fuel mixing chamber, which leads to the need to limit the mixing amount to control the temperature to maintain the engine working.

Many laymen just look at the thrust and feel that the new engine technology is not as good as it was decades ago, which is a complete lack of knowledge.

For example, a single-soldier rocket engine with only ten seconds of working time has a large thrust ratio. No one has ever praised this thing.

After country A packaged the aerospace industry to a private company, through a large number of damage experiments, a trade-off between thrust and characteristic specific impulse was performed to obtain the engine, and then the engine was filled according to the launch demand. This year, the three-core cascade installed a total of 27 The style of the engine has piled up the launch weight to more than 1,500 tons, and can deliver nearly 70 tons of payload into low orbit.

In addition, through businessmen’s pursuit of extreme profits, National Aerospace A also mastered the technology of steel-skinned rockets and first-level flea rockets.

The steel-skinned rocket is very special, which is the result of an idea of ​​reducing launch costs to the limit. There is no need for internal skeletal structure, no need for thermal insulation, and part of the load will burn out during launch. I don’t care at all. Just roll up a few millimeters of steel and weld each other to form the shell of the rocket and the load section.

The advantages and disadvantages are very obvious. The advantage is that the cost is extremely low, and the rocket shell can almost be ignored in the total cost. The disadvantage is that launch failure has become the norm. Even if it develops to this day, the 70% success rate is all because of heaven.

The flea rocket is a first-class rocket recovery technology, but unlike the general recovery from the sea, it is a technology that allows the rocket to fall back to the launch site through flight control.

As mentioned earlier, this technology often makes people misunderstand that the people of country A have extraterrestrial technology blessings. In fact, the first level of the flea rocket will not fly out of the atmosphere at all, because it has not gone out, and has not reached the orbital speed, and it does not fall back. Will suffer high temperature burning of nearly two thousand degrees at the highest point.

But I have to admit that as this technology matures, the first-stage rocket can be used three to five times repeatedly, and the shell can be used more times through maintenance, which has indeed greatly reduced the launch cost.

Based on the above accumulated experience and characteristic technology, country A is really capable of building a large space station without an electromagnetic orbital launcher.

It’s just that country A believes that with the deepening of human understanding of space, there are too few new technology growth points that can be obtained through the space station, and it is a waste of money to invest heavily in the construction of a new space station. It is not as good as prostituting other people’s homes. Space station program.

Now it is different. Level 2 monsters have appeared continuously, finally shattering the illusions of the vast majority of people, and the merchants finally can afford to make money.

As mentioned earlier, the most unacceptable space consortium proposed by country C is military integration.

For business people, the Kunpeng in Country C also has something they cannot accept-equality.

Kunpeng adopts the “resource point” trial method of resource management. The daily needs of its internal personnel are evenly distributed according to effective resources. To put it bluntly, it is a utopian environment.

This means that even the world's foremost rich person, after entering the Kunpeng space station, may be able to find a few flatterers, in principle, they will not receive any preferential treatment in terms of resources and living environment.

Dozens of people in the top ranks of country A occupy a total resource of even 8 billion people in the world. Calculated as a percentage, the master is not enough to describe it. More than half of the country’s overall output has been left behind. Can they accept to live on an equal footing with ordinary engineers and scientists?

What’s more tragic is that even if one or two of them can accept it, it’s useless, because according to the development plan of the Kunpeng Space Station, there will be no big money until the surface industrial production chain is completely paralyzed. The previous arrangements are all Engineers, scientists, and hard-working young scholars.

Therefore, after the continuous appearance of the second-level monsters, the bigwigs of Country A who felt that they also needed to find a way out, began to push Country A to launch the space station plan.

So there is the current situation. Country A plans to build a super space station with a gross tonnage of more than two thousand tons within one and a half years.

Two thousand tons is equivalent to five times the weight of the International Space Station in active service. Because there is no need to bear such heavy scientific research tasks, the effective volume ratio and material storage volume will be much larger, enough to provide a long-term life of about 20 people.

Then the question came.

Some astronomy enthusiasts and data emperors took out a set of photos taken on the ground of the future space station, and a small amount of translated electromagnetic orbit launcher rocket public information. After a meal, they calculated the result: the future space station is estimated to have two thousand. Four hundred tons, and from the analysis of the photos, the future space station using a new type of compressive material has a better content space than the traditional column space station. Country A’s plan is a waste of resources.

There are also netizens who point to the core, saying that the chaebols are already thinking about running away. However, this kind of debate is fierce, because most people in Country A feel that the chaebol is fully capable of building a safer, farther from the surface, and more sustainable underground shelters. There is no need to go to the space station and wait for death.

In fact, the underground refuge is of course under construction, but the chaebols, based on their previous investment experience, know that eggs cannot be placed in the same basket, which does not prevent them from investing a little resource on the space station.

However, these are not the main points. The most questioned is the shape and functionality of the country A space station.

The space station under the new plan of Country A intends to use more than a dozen cabins to form a polygonal structure, which will be rotated by additional small solid rockets after the personnel are in place.

Regardless of the structure or the method of rotation starting, it feels very fascinating. Isn't our country A the most technologically advanced country on the planet? Why did you design such a...well...inferior toy?

Then someone jumped out to give everyone popular science knowledge, telling everyone how much preparation work, how many manufacturers cooperate, and how many technical difficulties must be overcome to build a structure like the Kunpeng Space Station.

However, there have always been a lot of popular science texts, and no one reads it at all in the current network environment. Everyone continues to scold the department of the plan.

Country A’s efficiency was surprisingly high this time, and within four days, it came up with a revised plan.

It has become the same as Country C. First, build an intermediate platform, and then assemble parts and components to create a rotating space station that looks more like that.

The new plan quelled the anger of most silly people, but those who are a little more expert and those who can read by themselves and use translation software to read the official pages of the aerospace department of State C still scoff at the revised plan.

There are several key issues in this, and the official of country A has not given a reasonable explanation.

First, production capacity.

Since the monster crisis, country A has substantially increased its military expenditures, which has actually promoted the recovery of the industrial system. However, compared with the industrial monster that produces more than one billion tons of steel per year in country C, this new capacity is completely insufficient outside of military production. It supports a huge aerospace industry system that is several times larger than before.

Second, launch capability.

Country C uses electromagnetic orbital launchers to simplify the rocket structure and streamline the inspection process. With the full support of Country R and the limited cooperation of Xizhongzhou, can it support a three-space station (including the old space station, excluding the moon palace)的系统。 The system. Even if country A can make greater use of the power of West Central Continent, the complexity of traditional rockets will be higher. How can the frequency of successful launches be guaranteed?

The third ~www.wuxiaspot.com~ material.

From the reverse structure analysis of the pictures taken by astronomy enthusiasts, country C clearly mastered more than one kind of extraterrestrial material technology, and country A, which did not have space cooperation with country C (restricted by the law), wanted to create a relationship with C A space station of the same level as the country will inevitably consume more load, which means that the demand for the first and second conditions will further increase.

In fact, if country A abolishes the relevant bills and finds country C for space station cooperation before the start of the negotiations for the upgrade of UN to space UN, in line with the moral value of the common destiny of mankind, it is really possible to get the production quota for brick walls and bulletproof cloth.

However, country C has now fully recognized the reality that contradictions are difficult to reconcile. In order to avoid the hope of complete destruction of mankind in a close space war, other aspects have lost the foundation for starting to build space power on the same level.
