"This result may be different from the theoretical data. This is mainly because we cannot accurately predict the normal physiological state of people underwater, so naturally we cannot predict their oxygen consumption underwater."
"Because people's emotions will change when they are underwater for a long time, their heart rate and breathing rhythm will also change. Therefore, the demand for oxygen will also change at any time.
When resting, our breathing rhythm can slow down to about twelve times per minute. While exercising slowly, it can be maintained at sixteen times per minute.
The longer you stay underwater, the faster your breathing rate becomes, and the more oxygen is consumed. How long you can stay underwater depends on the user's usage habits and the environment.
Already."
At this point, Zhang Xiaolei glanced at the officer, and then continued: "In addition, to determine how long this underwater special warfare mechanical exoskeleton protective armor can stay underwater, in addition to oxygen, it also depends on the
Its battery life is up.
We have also equipped this underwater special operations mechanical exoskeleton protective armor with two of the latest super solid-state batteries, which enables its underwater and surface endurance to reach about eight to ten hours. Of course, we also provide it with
It involves a special underwater hot-swappable function. If necessary, the battery can be replaced at any time underwater, so that it can last longer.
Of course, this means that you need to carry additional replacement batteries and increase the weight."
After listening to Zhang Xiaolei's introduction, Lieutenant Colonel Zhao Chenggang and others in the Marine Corps also nodded. They naturally understood what Zhang Xiaolei said, and how long the battery life of this equipment depends on how they use it.
Zhang Xiaolei looked around the crowd, then continued with a smile: "In addition, we have also equipped this underwater special operations mechanical exoskeleton protective armor with a micro-sonar sound collection array for collecting and detecting underwater
The weak voice.
We know that visibility underwater is limited, often only a few meters or twenty meters, so there may often be brutal battles involving hand-to-hand combat.
With this set of miniature sonar sound collection arrays, we can sense the smiling sound in the water in advance, and then accurately locate the approaching target and respond calmly.
In addition, there are also electronic submersibles. We can use this electronic submersible to reach out of the water surface at a position of two meters underwater and observe the movement of the water surface.
It can also be extended into some small spaces for investigation. When not in use, it can be put away for easy portability."
After introducing these, Zhang Xiaolei took a breath, then led everyone to an adjacent booth, and then continued the introduction to everyone present.
“After introducing the basic performance of this underwater special warfare mechanical exoskeleton protective armor, the next thing I will introduce to you is the weapon system of this underwater special warfare mechanical exoskeleton protective armor.
First of all, like an ordinary mechanical exoskeleton, it has its own fire control system. This fire control system can not only control automatic weapons to attack, but also assist conventional weapons in attacking.
This underwater special warfare mechanical exoskeleton protective armor, like conventional mechanical exoskeleton protective armor, can also use a series of conventional weapons and equipment.
What's more special is that it can also use underwater weapons and equipment. Moreover, our engineers and weapons and equipment experts have also designed and developed a special underwater fire control system for the special environment of underwater combat.
Relying on this underwater fire control system and micro sonar array, we can achieve underwater beyond-visual-range positioning and beyond-visual-range attacks. The visibility our human eyes can observe underwater is about 20 meters, which is still in hydrology.
In very good circumstances.
Under normal circumstances, the bottom of the water is relatively turbid, and visibility is naturally greatly reduced. It is only about ten meters or even only a few meters away.
The situation on the ocean bottom is more complex, and visibility will vary from different areas. Even with the depth of the water, the water bottom gradually becomes darker, and the visibility chance will be equal to zero.
As for our fire control system, the micro-sonar sound collection array can accurately locate objects that emit weak sounds from tens of meters or even hundreds of meters away, and determine their type based on underwater soundprint information.
Once the identity of the target is confirmed, you can choose to launch an attack."
At this point, Zhang Xiaolei paused and looked at everyone's reactions before continuing: "We know that underwater individual combat mainly relies on underwater rifles, harpoons, daggers, hunting crossbows, and various other weapons.
Explosives.
As for these weapons, they can only be used for close combat. Even the underwater rifle with the longest range has an effective range of only twenty or thirty meters. The power of the bullet is greatly reduced at any further distance, and it is also a blind fire.
.
Underwater submarine operations rely on torpedoes and underwater submarine-launched missiles. However, submarine-launched missiles are generally used to attack surface ships and land targets.
As for underwater warfare, submarines mainly rely on torpedoes.
So can we equip this underwater special warfare mechanical exoskeleton protective armor with a miniature torpedo, so that it can also have a beyond-visual-range attack of 100 meters."
Based on this idea, we started the development of miniature individual torpedoes.
We all know that torpedoes are the most complex weapons in the world. There are only a handful of countries in the world that can independently produce torpedoes, which shows how technically difficult it is.
What we want to challenge is a miniature individual torpedo that has never been seen before, which also means that we have to solve a series of technical problems.
First of all, the size of this miniature individual torpedo must be small enough. The length must be controlled at about forty or fifty centimeters, the diameter must not exceed six or seven centimeters, which is the diameter of a thermos cup, and the weight must be controlled at ten kilograms.
one time.
Only in this way can it be easily carried and equipped on this underwater special warfare mechanical exoskeleton protective armor.
After solving the problem of weight and volume, we have to solve its most critical guidance method. There are many guidance methods for torpedoes. There is only one guidance method suitable for this miniature individual torpedo, active sonar guidance and passive sonar
Guidance.
Using active sonar guidance technology, we can allow micro individual torpedoes to attack targets positioned by micro sonar collection arrays. Of course, this method has a disadvantage, that is, a long optical fiber must be connected behind the torpedo for guidance.
data transmission.
This is the same as most anti-tank missiles, which have a long tail line.
