Tower Defense Strategy - Chapter 258

“Tower Defense Strategy (!

In December, just a few days after the first anniversary of the little monster giant clamp incident, the “Kunpeng” synchronous orbit permanently settled at the core of the space station and performed its orbit upgrade.

Along with it, there are five astronauts, three men and two women, and three Homo sapiens robots.

Kunpeng is by far the largest man-made aircraft with a radius of 130 meters!

The outer ring is not available for the time being, because it is too large. After all of it is completed, all the fuel extracted from the asteroid Supplyman 1 is consumed, and it is not enough to send it to the synchronous orbit.

The current personnel area is divided into two parts, the core column experimental area and the first-level microgravity living area.

The core column section, which is the central axis of Kunpeng, uses a classical round section cabin section… well, it was modified by welding and cold welding the large-diameter cabin section recently launched from Well No. 5.

In addition to maintaining zero gravity to support the experiment, the core column section, like the old space station, has a small number of beds, which connects the three-pillar support structure and the connection compartment.

The first-level microgravity living area is located in a three-pillar supporting structure 30 meters from the center of the circle.

From the core column section, enter the supporting structure core cabin through the cabin door. There are three 2.5-meter-diameter passages. There is a pillar in the middle of the passage. You can reach various areas by swimming along the pillars.

After starting to rotate, these pillars will become sliding rods. The closer they are to the outside, the greater the sliding acceleration. In the future, an internal freight lifting platform will be installed.

When the designed maximum speed is reached, the first-level microgravity zone is only 0.1 times the gravity, and it will be mainly used as a crop planting zone in the future.

During the orbit-up operation, the area has already been completed.

Different from the core column section, the cabin section here has become a rectangle, with a total area of ​​nearly 500 square meters, more than 1,100 cubic meters, because there is a 1.5-meter-wide side walkway freight line, which occupies nearly one-third of the area. The area of ​​the crop area can only be considered average.

However, the bottleneck of growing crops in space is electricity, and the area is more secondary.

At present, the crop planting in the first-level microgravity zone has not been spread out, and some of them will temporarily be used as exercise places for five astronauts, and there are also several berths that allow astronauts to sleep better under a little gravity.

There is room for expansion in this area, and a circle can be added to the side to turn the side walk into a central walk, and it will be fully integrated at that time.

The relevant cabin doors have been reserved, there are six in total, and these cabin doors are completely locked before the expansion is completed.

For the second-level gravity zone, and the outer section, there are only locked entrances and exits for the time being, and nothing has been built.

Kunpeng has the necessary “air conditioner”, but it mainly relies on radiant thermoelectric batteries to maintain the heat lost by natural heat radiation. When the scale of crop planting is spread out, the “air conditioner” has to cool down in turn.

It took three days for the Kunpeng core to complete the orbit-up operation and enter the synchronous orbit.

If you want to pay more attention to the symbolic meaning, you should be positioned above the capital. However, the latitude is too high and the subsequent comprehensive loss will be too large. In the end, the positioning point with a small change in the current flight angle of the future space station is selected.

Once in place, the solar array is unfolded.

…Its solar arrays are also divided into two types, one is traditional photovoltaic solar energy, and the other is a boiled water power generation device similar to a solar water heater. The latter is also part of the space station’s temperature regulation system, which is equivalent to an “air-conditioning” outdoor unit. The heat emitted by the internal temperature control unit will also be processed into electricity here.

The existing solar arrays are all on both sides of the three-pillar structure, rotating to avoid several predetermined gravity segments.

However, due to factors such as the workload of the future space station and surface transportation capacity, only half of the internally tested solar arrays have been deployed, with a total power generation of about 40 kilowatts. Through the kinetic energy device at night, it can maintain a survival of three kilowatts and use electricity for small experiments. They do not contain the output of thermoelectric batteries and energy storage batteries.

The power generation capacity of 40 kilowatts looks a bit outrageous compared to ordinary communication satellites with only two or three hundred watts. Actually, farming is not prohibited at all. This amount of electricity is not even enough to cover the first-level microgravity area with a layer of crops. It grows for 24 hours, not to mention multi-layer cabinet planting.

Regarding electricity consumption at night, Kunpeng has a follow-up component waiting to be assembled and manufactured.

It is similar to the existing kinetic energy device that maintains an output of three kilowatts, except that it is larger and heavier and requires a separate low-orbit launch. When the device is in place, it can achieve 10 megawatts of power generation and balanced output day and night.

With only a few tens of kilowatts of power generation, it seems a bit outrageous to prepare a kinetic energy storage device of ten megawatts.

But Kunpeng’s planned lighting, planting, oxygen regeneration, and other permanent power consumption, after the completion of the inner and outer three-circle basic cabins, will reach more than 200 kilowatts, including experimental equipment, internal processing equipment, etc., and it will not exceed the megawatt level. Long.

In short, as Kunpeng is the first place to preserve the seeds of human civilization, power protection is the top priority, and there must be no deaths due to lack of power.

December 20th.

The two asteroids, Developer One and Supplyman One, were wiped out by the future space station.

Relevant resource smelting and component subdivision have not been completely completed, but the separation and smelting of several important elements of iron, carbon, hydrogen and oxygen have been completed.

It is impossible to find asteroids anymore. After all, the cost of pushing the orbit around is there. It is better to use an electromagnetic orbit launcher to send semi-finished materials from the surface to the sky.

Mainly, the mining experience of the two asteroids is precious enough.

Country C has even established a pre-research group for the development of asteroid belts.

The development of the asteroid belt does not require you to capture it yourself like a low-Earth orbit. After eating an asteroid, give it a little thrust and you can reach the next asteroid in a month or two. If you don’t care about the size of the target or use more The thrust, the intermittent period can be even shorter, that is the real resource development, not the input is greater than the output as it is now.

The procedures for the last batch of separation work were set up, and it was time to change shifts again.

Most of the first group of future space station members, including Bai Qing, came back again, this time increasing the proportion of members of the Academy of Sciences.

The Yinglong-2 spacecraft was in charge of the crew going to the sky. With the first experience, Yinglong-2 had enough time to conduct various inspections and adjustments, and the process went very smoothly.

The ones that go down the ground use the recently launched escape double cabin. This cabin is relatively small, with a maximum diameter of 2.5 meters and a weight of more than one ton. The 3.35-meter silo can send eight up at a time.

The new escape capsule uses a water-drift reentry method to return. This method enters the atmosphere with a small angle of attack and will be bombed several times. It can gain additional deceleration time and cooling advantages without additional power, and only consumes the whole process. Ten kilograms of solid fuel gives the initial de-orbiting power. The disadvantage is that it takes a long time. Starting from the future space station, it will take two hundred minutes to return to the surface.

After this shift, there will only be a total of four spacecraft left in the future space station. Except for Yinglong-2, there is Yinglong-1, which flew back from the moon watch. The remaining two are in the best condition. Two early spacecrafts with a column diameter of 2.8 meters were used to carry out heavy cargo handling outside the cabin and space station maintenance operations.

For the two Yinglong spacecraft, No. 1 will carry out the follow-up moon watch delivery and robot transportation operations, and No. 2 will be piloted by human astronauts, responsible for the transportation of goods and personnel from the future space station to the Kunpeng space station.

The first task after the shift was to dismantle most of the equipment in the smelting team and project it to the moon.

Every resource in space is extremely precious, and no equipment will be wasted as a last resort. Therefore, when designing, it is necessary to consider the subsequent use after the mission is completed. s things.

The equipment of a metallurgical enterprise with a capacity of 10 million tons was carefully dismantled, and the parts and components were placed in separate categories.

A few days later, Yinglong One set off with three large boxes on his back.

The difference from the last time is that the three large boxes this time have a protective container, which has its own landing system, and will eventually fall to the ground at a speed of 10 meters per second or even lower.

Yinglong-1 landed smoothly again just a few hours after the moon watch, and XX23 has passed.

Summarize the past year.

No level 2 monsters appeared in December. Judging from the list provided by Octopus, they should appear in the first week of January.

This year, the loss of human population is about 160 million, of which 10 million are newly added. In addition to the monster losses in the last month and a half, about 3 million came from civil strife in various places, and the loss of more than 3 million in more than 40 days. The total value of the intensity of civil strife is close to the world. The war is over.

The total production capacity loss of human industry is about 17%, most of which is due to the destruction of the shipping system by small marine monsters and the inability to seek replacement of raw materials.

In terms of weapons, mankind produced the first version of laser weapons and electromagnetic weapons. In the last few days, country C built the first all-electric electromagnetic tank based on hexadecimal sodium batteries.

The space-based weapon still has only one death scepter, and the second death scepter is the next project of the future space station. It is expected to merge with the Kunpeng space station before the end of January.

Country C’s metal hydrogen bombs have begun to be sold in small quantities. Due to their limited production capacity, they can only be guaranteed within a few months to provide the ability to forcefully kill first-level monsters for most countries that remain basically stable. In this part, the countries of West Central Continent are greedy with the scolding of country A, and they also buy it privately, but because of attitude issues, they are “a little bit” more expensive than the supply prices in other regions.

Other countries with nuclear weapons ~ www.mtlnovel.com ~ because of their production capacity, they can only focus on the miniaturization and high efficiency of nuclear weapons. Some countries have begun to install nuclear bombs of 1,000 to 5,000 tons.

It is not easy to increase the efficiency of nuclear bombs, but under the same configuration, lightening itself will increase the proportion of chain reactions, which is conducive to improving the utilization of nuclear materials and increasing the sustainability of the nuclear industry chain. In addition, there are some other new issues, which will be raised during actual combat.

In the extraterrestrial science and technology part, of course, country C has gone the farthest, and other countries are not idle.

It is estimated that by the end of XX24, there will be at least twenty research results of extraterrestrial technology and in-game reverse engineering that will be put into practical application.

On the whole, the human experience in XX23 was relatively bad, but it was not so bad as to lose hope.
