Wang Qi had never considered working on an ultra-low-temperature alien planet before, but now that he thought about it, it would be quite difficult to make a space suit.
Without atmosphere, it is actually just the point with the least difficulty.
As long as the clothing can pass the watertight test, the airtightness verification is very simple. Just build a spherical cabin, inflate the garment and then vacuum the cabin.
A weak temporary leakage is not a big problem, because the life-sustaining module will definitely be carried by then.
The reason why it is called a life-sustaining module rather than an oxygen cylinder is that there are too many unknown situations to deal with, and if a simple oxygen cylinder is used in a closed environment, it will accumulate carbon dioxide, which is a fatal factor.
With Solaris opening the door, the round-trip cycle will not be too long, so the life support module does not need to consider such technically difficult things as high-proportion water circulation.
There are three main functions: oxygen supply, carbon dioxide recovery, and energy group.
The oxygen and carbon dioxide can be added in the form of medicated powder in a small cylinder. The medicament is sodium peroxide, which can absorb carbon dioxide and release oxygen. The cylinder mainly prevents accidental leakage and maintains internal air pressure.
In the past, the shelter also had a special carbon dioxide recovery device. If it could be integrated into the backpack, the powder would not be needed, but only if the new magic could be used in that place.
The real difficulty is ultra-low temperature, which is an area that even Wang Qi's world space suit did not touch upon in his previous life.
The spacesuit is said to be able to withstand minus 150 degrees to plus 120 degrees, but the actual low temperatures it needs to deal with are not that serious, but more high-temperature conditions.
In a near-vacuum environment, heat will not be taken away by the gas because there are few gas particles. The situation in the movie that freezes immediately upon exposure to space is not scientific at all.
The loss of infrared thermal radiation can be completely ignored with the help of the spacesuit insulation layer and constant temperature system.
The so-called low temperature that the spacesuit copes with comes from the heat exchange at the gripping and stepping areas on the dark side of the space station.
The space station orbits the earth every ninety minutes, and the sunny side will be heated to between 100 and 200 degrees. Sometimes, due to factors such as stellar activity or cooling device maintenance, it needs to be exposed to the sun more evenly, and the temperature on the negative side will not drop. to too low.
What Wang Qi will face next is likely to be an ultra-low temperature environment with a temperature below minus two hundred degrees, and there is still some gravity.
There is also a huge hidden danger in the ultra-low temperature non-artificial environment. A large amount of solid gas looks like stones. Once these stones are heated, they will liquefy or even explode directly.
This explosion is naturally not a chemical reaction caused by mixing with oxygen. It is simply a lot of gases in a pressure-free environment. There is no intermediate state of liquid, and the temperature rises and it directly becomes a gas.
Solaris made it clear that you might not be able to fall back after jumping, so you should try to avoid such an explosion no matter how slight it is.
A lot of work goes into the soles of your feet, and the same goes for your gloves.
In the atmosphere, it is no problem to say that still air hardly transfers heat. Most of the so-called double-layer insulated containers take advantage of the low thermal conductivity of air. Compared with vacuum double-layers, air insulation can make the material thinner and save money. some costs.
But there is a characteristic of heat conduction. The greater the temperature difference between inside and outside, the higher the conduction power.
For a good thermos cup, if the lid is not opened at all, the boiling water will drop to the body temperature range in 12 to 16 hours. The vacuum type can extend the time by more than half. The reason why there is still a change is because the inner and outer layers cannot be completely separated. There must be supporting structures and connection transitions.
If the temperature difference between the inside and outside is increased from 70 degrees to 230 degrees, due to the increase in heat conduction power of the same material, the time for the internal liquid to return to the body temperature range will probably be less than doubled, not twice.
The difficulty with the gloves and shoes of the space suit is that they have to be mobile, which is much more difficult than getting a vacuum steel frame.
Similarly, leaving relics there will inevitably involve a lot of work, which will lead to changes in the temperature of local materials, and there are a huge number of uncontrollable factors.
Unless it is a high-purity iron celestial body, without magic, many problems will be difficult to solve in a short period of time, and it will be impossible to wait until the door is opened to make on-site adjustments.
Magic is a crucial factor.
Solaris said that many magics cannot be used, but there must be some that can be used.
Which ones can be used and how the effects are attenuated. This set of results must be obtained in order to make a spacesuit that can complete the mission.
Let Solaris open the door in advance to test it out?
Putting aside whether he will be obedient or not, he must at least have the conditions to complete the test in a short time.
After sorting out the difficulties, Wang Qi began to arrange projects.
The main work is divided among three units.
Blue Sky Heavy Industries is responsible for the basic spacesuit.
Because there was a previous expectation of a decrease in atmospheric pressure, in addition to respiratory masks for 400 to 600 Pascals, the pre-research work on breathing tools for lower pressure environments fell to Blue Sky Heavy Industry. In order to test the new generation of turbojet aircraft, they have also established a flight life support research group. A series of life support-related things including load-resistant flight suits, oxygen/temperature support, etc. are studied here. Pre-research is equivalent to this group's Leisure work, no time pressure, just make progress every year.
Now we need to transfer some people and formalize the work into a small group. The changes will not be too big. The two support systems including sample production and testing will basically not be touched. It will just increase the number of researchers and engineers.
The second unit is the basic magic research project of the original Magic Weapon Research Institute. They are currently recruiting personnel and will be separated into a new magic research institute after a while, responsible for the basic theoretical research of magic.
Their task is to analyze the magic required for the task, and then make some testers based on different principles and frameworks.
For example, magic electricity conversion can be done with old-fashioned magic, but the current is difficult to control. In addition to the old and new theoretical systems, if there are certain family secrets in the database, you can also try them out.
Magic electricity conversion is not irreplaceable, but in terms of batteries, the Phoenix Kingdom only develops lead-acid batteries, which have a particularly low energy-to-weight ratio, and magic power storage based on artificial gemstones. The electricity converted is not of the same order of magnitude. If there can be a solution here, The task will be much simpler.
There are also requirements for testers.
First, the impact of the magic released must be small, and it is best not to affect things other than the tester; second, whether the magic is effective or not, it is best to directly display it to the task personnel by turning on a light, and do not make artificial judgments.
The third unit is the manufacturing bureau under the former research institute. It is now renamed Cliff Industry. This brand was given to them for temporary use when they were building the power mecha for Cliff Mine. Now the name has been changed and it belongs to the same company as Blue Sky Heavy Industry. , belongs to both the National Academy of Sciences and the National Defense System.
Their job is to cooperate with the basic magic research team to make testers, and also to cooperate with Blue Sky Heavy Industry to prepare some modules required for the mission.
Wang Qi still didn't want to ask Solaris to open the door once, twice or three times. He was not a subordinate and was uncontrollable, so he acted as if he only had one chance to open the door.
The magic modules that Cliff Industries will prepare serve this purpose.
Cliff Industry itself is a mass-production factory for magic equipment. It is used to make many types of magic equipment. Each type only requires a few sets. Without a production line, there are not enough people, so it is subcontracted to private magic workshops.
As for the execution of the mission, it is naturally the job of the military. Considering that the sharp tail and elbow bone blade cannot be used as a space suit, we can only choose a few people from the Night Clan, and Wang Qi will add some attributes.
Physical and mental attributes may be useless in an ultra-low gravity environment, but a few extra seconds of survival in the event of an accident will give you a greater chance of recovery, and it can also shorten the time for ground training.
