After completely leaving the submarine and at a safe distance, the rescue team held the rudder tightly and controlled the shuttle-like No. 901 'Pufferfish' thruster to turn to the right, aiming at the red buoy area, and the thruster power system was operating at full power. , with a maximum speed of 30 knots per hour, quickly heading towards the Zhouhai Sea more than 200 meters away.
"Buzz!"
The subtle motor sound in the annular pump push tube comes out, melts into the sea water, and is transmitted around.
The high-performance fuel cell stack continues to provide abundant energy support. The high-performance integrated motor located inside the annular pumping guide tube operates at full load, driving the pumping tube equipped with propeller blades to rotate, generating thrust, and countless tiny microscopic particles emerge from the end of the tube. The dense bubbles leave a white trail.
Extremely quiet!
The No. 901 'Blowfish' propeller, which operates at full power and has a noise of only 95 decibels, was controlled by the rescue team. After sailing for about 190 meters, it reduced its power output, slowly decelerated, and gradually approached the red buoy, preparing to attack the predetermined area. Zhou Hai, who was waiting inside, launched an underwater rescue.
Countless tiny and dense white bubbles gradually floated up and condensed into one, forming a distinct white navigation track, which appeared in the eyes of everyone on the shore.
Watching the white sailing track heading towards the Zhouhai Sea in the red buoy area, everyone on the shore had their eyes solemn, holding their breath, not daring to take a breath, and watched the situation in the water closely.
At this moment, the most critical part of the simulated boat boarding training has arrived, underwater docking!
In the water, Zhou Hai, who had been waiting for a long time and had already noticed the movement, looked at the tens of thousands of white bubbles on the water. He calmed down and responded immediately. He took a deep breath and dived again while holding his breath. His limbs moved slowly and he was suspended in the water at a depth of three meters. , waiting quietly in the blue water, strictly following the standard procedures for docking operations.
As a carrier-based aircraft pilot who crashed and fell into the water, during the underwater docking process, he only needed to dive and hide and wait, without requiring too many operations.
The whole person stepped gently on the sea water, staring at the shuttle-like appearance of the No. 901 'Pufferfish' propeller dozens of meters away.
"Buzz!"
As the operating power of the propeller power system gradually decreases, the sound of work becomes smaller and weaker.
The annular pump retreat guide tube rotates counterclockwise and reverses to slow down.
The driver of the rescue team held the steering wheel tightly with both hands and stared at Zhou Hai, who was already in sight. He steadily controlled the No. 901 "Puffer" that had been reduced to a safe speed, crossed the last distance, and accurately sailed into the red buoy area. , arrived at a position about five meters away from Zhou Hai and stopped smoothly, maintaining a hovering state.
Then, the pilot quickly signaled to Zhou Hai to indicate that he was close to docking and ready for underwater rescue procedures.
Seeing the special sign language from the driver, Zhou Hai, who was waiting for the dive, immediately responded, typing the standard special sign language, indicating that he had received it and executed it immediately. He immediately swung his legs and swam towards the No. 901 'Pufferfish' propeller, quickly Get close, ready to dock.
At the same moment, the second rescue team member who was in the co-pilot position immediately stood up and left his seat. His legs were covered with flippers shaped like frog toes, and he stepped on the seawater to meet Zhou Hai, who was swimming from the right.
"Wow..."
As the second rescue team member paddled the water with his fins, a subtle but noisy sound of water came out and surged around.
The two of them swam towards each other, covering a distance of just a few meters.
Soon, after Zhou Hai came into close contact with the heavily armed rescue team, the other party immediately took out a special oxygen tube about 1.5 meters long from his diving equipment and handed it to Zhou Hai.
Zhou Hai did not hesitate, took the oxygen tube with his hand, put it in his mouth, took a breath of fresh air, exhaled the carbon dioxide through his nose, re-established the oxygen supply and circulation system in the body, and no longer held his breath.
In the underwater docking process, the first thing that needs to be docked is oxygen. ——
In this afternoon's single-person diving equipment wearing training session, all participants used breath-holding behavior to complete the wearing. The purpose was to improve the training effect.
This would not be done in a real battlefield environment. The first thing the rescue team does during underwater rescue is to supply oxygen to the diving carrier-based aircraft pilot and re-establish the oxygen supply cycle.
"Gulu..."
White bubbles enveloping the seawater emerged, rolling up and down like boiling, and rising toward the surface of the water.
These are all carbon dioxide that is useless to the human body.
Breathing the fresh air from the oxygen tanks of the rescue team members, Zhou Hai and the second rescue team member came to the side of "Pufferfish" No. 901. Immediately afterwards, the other party took out a brand new oxygen tube from the fourth seat of the thruster. tube, and handed it to Zhou Hai again, signaling for replacement.
Zhou Hai nodded, indicating that he understood, took out the oxygen tube in his mouth, and replaced it with the oxygen tube supplied by the propeller.
After doing all this and completing the oxygen replacement, the second rescue team member went to the storage compartment behind the thruster, took out the heavy single-person diving equipment, and then handed it to Zhou Hai, raising his right hand and holding up three fingers.
three minutes!
Carrier-based aircraft pilots must complete the donning of single-person diving equipment in the underwater environment with complete equipment and no assistance for three minutes.
This is the qualifying line for simulated boat boarding training and donning training.
Looking at the three fingers raised on the rescue team's right hand, Zhou Hai nodded in response. Without delay, he immediately took over the 40-kilogram Type 19 high-performance single diving equipment, stepped on the propeller, used it as a support point, and then put it on. .
The Type 19 single-person diving equipment was developed in 2019. It is a wet type and belongs to the sixth generation of military single-person diving equipment. It is the latest individual diving equipment developed by the Navy for the frogman troops. It is complex and advanced.
The complete set of diving equipment consists of a series of components such as a diving mask made of bulletproof glass, the latest military high-performance carbon fiber diving suit, lead weights, frog fins, diving watches, diving gloves, diving knives, diving instruments and diving tablets.
Warm and cold-proof, the difficulty of wearing is greatly reduced, it is convenient and simple, and the comprehensive performance is comprehensively improved. It supports diving depths from 0 meters to 100 meters. It is extremely versatile and applicable, whether it is the cold sea in the north or the warm sweat of the equator. .
Well, to be precise, it can be called globally applicable.
After Zhou Hai started wearing the equipment in the underwater environment, the second rescue team member simultaneously pressed the timer button held tightly in his right hand to start timing.
"call……"
A series of white bubbles came out of his nose, and Zhou Hai took a breath of fresh air. He held the equipment bag in one hand and took out a high-performance carbon fiber wetsuit with excellent elasticity and tightness in the other hand.
The wetsuit is painted black and gray. Open the backup zipper. From top to bottom, the legs go in first, then the hands and torso, and finally emerge from the top. The process is a bit laborious, mainly because it must resist the elasticity and elasticity of the suit itself. tension.
After putting on the main carbon fiber diving suit, Zhou Hai took out a series of diving parts one by one from the equipment bag, put on the frog fins, put on the bulletproof mask, then installed the scuba connection to the oxygen bottle, and adjusted the breathing switch. .
Everything, methodical, intense and fast.
Although, the whole wearing process seems extremely cumbersome.
Not long after, Zhou Hai stuffed the diving knife into the equipment belt around his waist, adjusted the breathing switch to turn on the oxygen bottle, spit out the oxygen tube supplied by the propeller, and took a breath of oxygen from his own oxygen bottle. The entire wearing process came to an end. .
After doing all this, Zhou Hai raised his right hand to indicate that he was finished wearing it.
"Ding!"
The second rescue team member pressed the button on the waterproof timer at the same time to pause the timer.
The time is frozen at 2:25 seconds.
Looking at the number displayed in the timer, the second rescue team member was startled for a moment, with a look of surprise in his eyes. As a frogman on the 093G nuclear attack submarine Jinling, this was his first time participating in the rescue of a carrier-based aircraft pilot. Training, but he already understood the weight of the number in the timer.
A new wear time record!
Raising his right hand, the second rescue team member immediately gave Zhou Hai a thumbs up, expressing his inner admiration, and then used sign language to give the next step of instructions——
The docking is completed, fasten your seat belts, prepare to depart, ah no, prepare to return.
PS: Yesterday was the birthday of the J-10, so here’s a belated birthday update.
