Chapter 2607: New technology that allows frogmen to dive for a long time?
"Although the mechanical exoskeleton on this set of underwater special warfare mechanical exoskeleton protective armor is mostly made of lightweight polymer composite materials and carbon fiber materials, with a small amount of metal materials, it does not affect its strength and load-bearing capacity at all.
The power of the assist system of the entire mechanical exoskeleton system can reach 90% of the special mechanical exoskeleton protective armor introduced earlier, and the support system can bear about 80% of the special mechanical exoskeleton protective armor.
This also means that it can carry more supplies and more weapons and equipment. For example, conventional diving equipment can only carry two gas bottles, but our system, with its super load-bearing capacity,
You can carry more and more gas bottles as long as you can carry them on your back."
At this point, Zhang Xiaolei paused for a moment, then changed his tone and said with a smile: "Of course, we think it is stupid to carry more gas cylinders to extend the underwater combat time.
An ordinary cylinder can probably supply our divers with underwater activities for about an hour. If the dive is deeper, the consumption of air will be greater. So usually, in order to ensure that our special forces and frogmen
If they stay underwater for a longer time, generally we will equip them with two gas bottles, and some may also add a small emergency gas bottle in addition to the two gas bottles. This is basically the case. Even if these are counted
According to the activity depth of ten meters underwater, it can only be used underwater for about two to two and a half hours.
This time is too short, which greatly limits the underwater combat effectiveness of the special operations team members and frogmen.
So, can we use new technologies to allow our special forces and frogmen to stay underwater longer?”
Hearing Zhang Xiaolei raise such a question, everyone present couldn't help but start talking, but the navy personnel generally shook their heads. If so, why are they still carrying oxygen bottles? Obviously
No.
Zhang Xiaolei stopped and gave everyone present time to react, communicate and discuss. By the way, she also took a sip of water handed over by the staff and breathed a long sigh of relief. After talking for so long, her voice was already a little hoarse.
.
However, such an opportunity today is very rare. No matter how hard she works, she still has to sell these products one by one and strive to get more orders.
Except for the last time she went to the Bear Country in the north, this should be regarded as the first project that she was officially responsible for after taking over Haoyu Industry. Naturally, she wanted to make achievements and prove her ability to Wu Hao, and also to go down.
Convince the public.
She knew very well that there were still many people in the company's entire military industry system who had strong objections to her being the general manager. So she also wanted to achieve results as soon as possible and shut up all those who doubted her.
Seeing that everyone was almost communicating, Zhang Xiaolei said with a confident smile to everyone.
"Of course, our technical team has made a breakthrough in this technology through hard public relations."
Hearing Zhang Xiaolei's affirmative and confident answer, the people present started to make noise again, obviously not believing Zhang Xiaolei's answer.
Zhang Xiaolei, who once again gave everyone a little time to react, slowly introduced them with a smile on her face.
We all know that 78% of the air we breathe is nitrogen, only 21% is oxygen, and 1% is carbon dioxide and other gas impurities.
Among them, only oxygen is needed for our heart, lungs, and blood oxygen circulation. The other components are useless and do not participate in our human body's respiratory, blood and oxygen circulation activities.
In this case, do we only need oxygen and no other gases? Oxygen can be liquefied, making it easier to store.
Obviously this is not the case. The oxygen concentration we need is about 21%. Anything higher than this is called nutrient-rich. People will become very energetic, but living in a nutrient-rich environment for a long time will damage the human heart and lungs.
function, which accelerates the decline of the human body.
If the oxygen content further increases, people may suffer from oxygen poisoning, and inhaling high concentrations of oxygen for a long time may even lead to death.
So this is why diving tanks contain air instead of oxygen.
Of course, if the oxygen concentration drops below 21%, hypoxia may occur, which may damage the functions of various organs of the human body, lead to behavioral confusion, or endanger life in severe cases.
So can we only give people 21% of the oxygen in the air every time they breathe? Isn't that okay?
Deliberately raising such a question, Zhang Xiaolei glanced at everyone, and then shook his head, saying no: "This is also not possible. Although the 78% of nitrogen does not participate in blood oxygen circulation, it does participate in breathing.
Among them, it can make our lungs fuller when breathing, so as to inhale more air, so as to obtain more oxygen. When exhaling, these waste gases can also be discharged as much as possible.
Therefore, although 78% of the nitrogen is useless to the human body, it is essential for breathing.
So is there a way to directly allow the human body to absorb an appropriate amount of oxygen without using this nitrogen? The answer is yes.
This is an artificial lung, which can directly connect oxygen to blood proteins in red blood cells without passing through the lungs. In this way, we only need a small amount of oxygen to maintain people's blood oxygen needs for a long time."
Hearing Zhang Xiaolei's bold idea, everyone present shook their heads. Obviously, everyone still couldn't accept this idea or this idea.
Moreover, a set of artificial lungs is too expensive and is not suitable for equipping individual soldiers. Moreover, this kind of artificial lung is also traumatic for personnel, which is obviously not suitable for combat.
"Of course, this technology is theoretically possible, but it can only be used to save patients and is definitely not suitable for military operations. On the one hand, of course, the artificial lung, that is, ECMO, is too expensive; on the other hand,
Because this method is invasive to the human body. It also requires stopping lung activity and changing breathing habits, which is also detrimental to the human body. It is obviously not suitable for equipment use unless absolutely necessary."
Hearing what Zhang Xiaolei said, everyone looked a little better, and then became more and more excited about what technology she was going to introduce. It can actually allow people to live underwater for a long time. This is incredible. Could it be that artificial gills have been developed?
.
This is impossible. Countries around the world have been developing it for such a long time without making any progress. Can Wu Hao and the others really do it alone? Everyone can't help but question it.
