Tower Defense Strategy - Chapter 320

Everything went well. On October 20th, the first moon baby Xihe was born.

　　 The official name is Xihe directly. On the monthly table, the couple did not give her a new name, just an extra surname.

The smooth birth of 　　 Xihe is not only a major achievement in the aerospace system of country C, but also has a bearing on the future of all mankind.

　　Modern medicine has guaranteed the safety of the mother and child when Xihe was born. Then, as long as the health of the bones and blood circulatory system in the low-gravity environment is solved in the infant and toddler period, the continuation of self-reproduction of astronauts can already be seen.

　　 For these follow-up tasks, there is no need for new equipment, and they mainly rely on remote support from surface nutritionists and medical experts.

　　 So even if mankind loses all surface launch capabilities now, the remaining mankind can still look forward to the future.

　　 Once the news was made public, it caused a global sensation… but it was only a slight sensation.

As the overall industrial power on the ground continues to weaken, it is impossible to launch a new space permanent residence system during this period. At the same time, in order to ensure the living space of new humans in space, a small amount of expansion work cannot provide more access tickets to the surface. .

　　 So the news is good news, but it has no direct relationship with the people on the surface who can also watch TV online.

　　 In addition, the old problems of country A have been committed again. Seeing country C showing the limelight, some people who were affected by the demonization spread in the past can’t hold back, and they start to work together.

　　 A few mouth-mouthers appeared first. At the end of October, the spokesperson of the General Commander’s Office suddenly announced that the Doomsday Space Station would increase 150 places, and the hot spots would naturally shift over.

　　 Previously introduced the per capita material conditions for permanent residence in space and the launch capabilities of various regions.

　　 150 places, corresponding to nearly 10,000 tons of materials and buildings, can not come out by blowing a bubble, where does the extra launch ability come from?

　　The answer is…the big country A has also used electromagnetic orbital launchers.

　　 Country A had the ability to produce black and white magic guides as early as last year, but due to the impact of scale, fluctuations in the cost of silver raw materials, and the depreciation of A currency, it has been unable to enter large projects.

　　 The scale and quality of the Doomsday Space Station are related to the continuation of the offspring of the chaebol. The funding guarantee is sufficient. The problem is that under the environment of rapid currency depreciation, there will be fewer things that can be done only with funds.

　　 Another problem is the deep-rooted dilemma of high-tech cooperation between A and C. This is a question left over from history, and the dominance of the space level is superimposed on it.

　　 Country A cannot obtain the full set of technical data of the electromagnetic orbital launcher directly from Country C. It relies on the Xizhongzhou launcher and construction data for reverse engineering, supplemented by local research, and it takes time to master and learn to build.

　　 Until this time, their electromagnetic orbital launcher has only started construction.

　　 Most critics believe that the transmitter is too late to be fully loaded.

　　 It seems that the development of the transmitter in country C is smooth and smooth, but there are many problems that need to be solved.

　　 The instantaneous load of the 3.6-meter caliber transmitter is more than that of an industrial city with a population of 500,000. At the same time, to ensure the safety of the transmitter itself, it is necessary to power up some time before launch.

　　 In addition to cooperating with the logistics of the launcher, it does not mean that once the launcher is on the ground, everyone will be able to order it. It will take at least a few months to coordinate the production and logistics of various manufacturers.

　　 Excluding country C, ARE is the fastest-improving efficiency of electromagnetic orbital launchers in the world.

　　 According to the calculation standard of the average daily delivery volume in low-Earth orbit, the ARE launcher still had a 15% increase in capacity last month compared to the previous month. According to the analysis of relevant agencies, it will take at least a year for the average daily capacity to approach its peak.

　　 Even if country A is stronger, it is always necessary for eight to ten months.

　　 Based on the changes in the supply of industrial products in recent months, there will be problems with the procurement of rocket parts.

　　 Related dilemmas, the launchers of country A do not understand, but there is no way.

　　 The capital drive needs to see profit before action can be taken. In the early stage of the monster crisis, when the outcome of the monster crisis is uncertain, superconductors, electromagnetic rockets/silos are not sufficiently funded to advance, and they will definitely be a step slower.

　　 On the other side of the planet, country C is preparing for the final big move of the astronaut system, the future space station upgrade.

　　 The future space station is now about 600 kilometers above the surface. The original plan did not intend to orbit before the collapse of the surface production system.

　　 But the plan can’t keep up with the changes.

　　 After the accident in the Great River Delta, the space three-station system began a rehearsal of autonomous operation. Astronauts commanded the three stations and required the use of as little reserve materials as possible.

　　 Three months have passed, and all the information that should be counted has been obtained.

The overall construction basically meets the needs of life and production. According to the collected information, Yuegong needs to provide Kunpeng and the next two stations with a total weight of about 120 tons every six months, and at the same time recover about 60 tons of non-renewable garbage on the space station. .

　　 is slightly different from the garbage classification on the surface. The space station is non-renewable, but there is no equipment for disposal in the space station, but there is in the moon palace. The real non-renewable garbage only accounts for less than 10% of this part.

　　 The space station system meets the self-sustaining requirements. The surface and the Moon Palace commander negotiated and decided to upgrade the future space station in advance.

　　 Low orbit is affected by scarce atmospheric particles, and a lot of maintenance work is required every year. After the orbit is upgraded, the situation will improve a lot.

　　 But at the same time, the material transfer station of the future space station and the outer space vehicle assembly station are lost in low-Earth orbit, and the replenishment efficiency of the surface to the space system will be reduced.

　　 After the birth of Xihe, the future space station will once again enter the stage of major engineering.

　　 Its newly-built circular residential area and the original construction area need to be adjusted relatively to meet the requirements of the promotion of the rail.

　　 Its annular area adopts different design concepts, it is very small, with a total diameter of 60 meters, less than half of Kunpeng.

　　 In appearance, Kunpeng’s annular area looks like several concentric circles, while the future annular area will be skewed towards a roller type, which means that the width of the first floor is much larger.

　　 The rotation structure is also completely different. Kunpeng will provide the rotation power for the shaft. In the future, there will be an outer frame outside the drum, and more small motors will provide the drum rotation power.

　　 Both have their own advantages and disadvantages.

The structure of 　　Kunpeng is more convenient for equipment monitoring and management, but the parking of the spacecraft has become a problem, and it can only be parked on the stationary column or stopped in the ring area.

In the future, the outer frame drum will not stop if several motors are broken. The frame provides a space for the spacecraft and does not affect the internal rolling (like a washing machine). At the same time, the outer frame, solar energy, and heat dissipation equipment can also provide extra for the living area. Protection.

The disadvantage is that gravity is not good and is limited by the diameter. When the roller simulates gravity above 0.15g during rotation, the human body will feel obvious lateral force, and it will be crooked when standing. As a result, the daily gravity is only 0.085g. Floating in the suborbital makes no difference.

　　 But even if it is less than 0.1g, at least it is more suitable for humans than zero gravity.

　　Before the orbit upgrade, the future space station needs to send the original working platform to the drum for internal testing and park, and a lot of fixed work will be carried out to achieve an integrated orbit upgrade.

　　 The time soon came to December, and after the fuel reserve reached 1,600 tons, the future space station would perform an orbit upgrade.

　　 The total weight of the current future space station is about eight times that of the asteroid mined at the beginning ~ www.mtlnovel.com ~ tons of fuel, which is only enough to reach an altitude of 2,100 kilometers, and even new engines are used.

　　 Dan bird, this is probably the last legacy left by the surface in terms of engines.

　　Dan Bird is a proven atmospheric shuttle engine, which descends to a height of 30,000 meters, can open the external air intake, and switch to the super combustion ramming mode.

　　 However, it is still ostentatious. The specific impulse, thrust, and reliability in the atmosphere are not well done. The only thing that can be seen is that the specific impulse can reach 480 in the outer space, which is close to the limit of the hydrogen-oxygen engine.

The specific impulse of 480 is really not low. In order to pursue the reliability under high thrust, the specific impulse of the conventional rocket’s first stage is often not reached by 300%. Under the function of atmospheric reciprocation and partial deformation, Danbird can make the vacuum impulse. By 480 seconds, almost all the achievements of country C in the hydrogen-oxygen engine have been integrated.

　　 It is a pity that nuclear power and plasma are more promising in outer space.

　　The nuclear power ratio of the drought has exceeded 1,000. Although the thrust of the plasma thruster is small, it can be considered as tens of thousands of energy.

　　 Therefore, Dan Bird is more practical than practical, and it is more coordinated with related materials to provide astronauts with a reference for development.

　　After the space station is upgraded in the future, the surface will no longer provide resource-based and equipment-based supplies for the three-station system. It will only supply the mechanical hard disk database, as well as canned meat and dried meat reserves that are still insufficient in space self-sufficiency.

　　 The newly released database is no longer the seeds of human civilization in the past. It is sorted by pure knowledge, knowledge with explanations, video lectures, etc. I don’t know how much it can be sent. Anyway, collect it and ship it up.
