The next day.
In the early morning, the morning sun rises, and a soft and weak ray of sunshine emerges, illuminating the entire world.
Training base, venue three, is full of various training facilities and equipment.
"Unity is strength, unity is strength, this strength is iron, this strength is steel, harder than iron, stronger than steel, towards the Dharma..."
There was a faint sound of singing coming from Field No. 2 in the distance. The third-year flight cadets were doing exercises, singing loudly as they ran.
The song is the most classic "Unity is Strength", which has been sung countless times.
"Pfft!"
At the top of the poplar tree at the edge of the field, a sparrow stood on a slender branch. It seemed to be disturbed, and it flapped its wings and flew away quickly.
"Zhou Hai, first of all, you must understand the meaning and concept of skydiving. Parachuting refers to the act of using resistance after jumping from a high altitude, using a parachute to slow down the descent, and finally landing safely. This is an important thing that every student pilot must master. One of the techniques, skydiving is centered on the parachute.”
Wearing a blue short shirt, Tan Gang looked serious and explained the knowledge and skills about skydiving to Zhou Hai in front of him: "The parachute is an aviation tool that uses the principles of air resistance and wind. Regarding the principles of air resistance and wind, You should understand..."
"Understood." Zhou Hai was wearing training clothes. After hearing Tan Gang's detailed explanation, his inner understanding of skydiving became more thorough and clear.
Tan Gang nodded and continued to explain every step and detail about skydiving, what actions to take before landing to avoid injury, folding and opening of parachutes, etc.
Time passed slowly, and Tan Gang taught important knowledge about skydiving one after another.
"Have you remembered everything I said?" After about thirty minutes of theoretical class, Tan Gang said seriously with a slight sweat on his forehead.
Zhou Hai nodded: "I remember, do you need me to repeat it again?"
"Please memorize the key points of knowledge about roll landing." Tan Gang said with a calm expression, staring at Zhou Hai with sharp eyes.
"Tumbling skydiving landing refers to the landing posture after a set of standard skydiving movements." Zhou Hai, doing a straddle movement, held out his chest and slowly recited the key points of knowledge:
“When a skydiver lands at high speed, the skydiver must coordinate his or her posture and, through body joint flexion and rolling, disperse the impact energy with the ground to as many parts of the body as possible and to parts that are insensitive to impact, and at the same time prolong the duration of the impact. time to avoid excessive instantaneous force on parts of the body, thereby reducing the probability of injury. A simple summary is - rolling on the ground, releasing force to reduce injuries."
"That's a good summary. Come here and show you the parachute."
Tan Gang nodded with satisfaction, turned around and motioned for Zhou Hai to come over, squatted down, and opened the yellow-green military parachute bag on the ground: "This is our army's new generation parachute. It is a round parachute, made of ultra-high-strength polyethylene fiber and composite materials. It is also equipped with a three-ring release device. Generally speaking, a parachute is divided into a main parachute and an auxiliary parachute. The main parachute is opened first. If the main parachute fails, the auxiliary parachute is opened."
The yellow-green military parachute bag is open, with complex internal deconstruction, and contains a white soft and tough round main parachute and auxiliary parachute.
"What if the parachute also malfunctions?" Zhou Hai stared at the yellow-green painted parachute bag, thought for a while, and pondered.
"There are two options. First, stay calm before landing and manually repair the faulty main or auxiliary parachute. The landing will be rewarded with third-class merit."
Tan Gang smiled lightly, with a free and easy expression on his face, and his words were relaxed and indifferent: "Second, he fell vertically to the ground and was shattered into pieces. He was posthumously awarded the title of second-class meritorious service and martyr. Of course, personally, I hope this happens. , you can get third-class merit instead of second-class merit."
"..."
Zhou Hai fell into silence.
“There are many types of main parachute failures. The main parachute cannot be pulled out from the packing bag, the main parachute does not expand, the parachute rope is knotted, part of the parachute rope breaks and fails when opening the parachute, the canopy is damaged and torn, the main parachute is partially inflated, etc. wait."
Tan Gang's expression did not change and he continued to explain: "Under the three-ring release device of the parachute bag, if the main parachute fails, you can cut the parachute rope and abandon the main parachute, but you have to hope that the auxiliary parachute opens normally."
Every failure is a lesson learned with life and blood.
Various accidents and tragic accidents occur every year in the airborne troops and the civilian parachute community. It is not uncommon for the main and secondary parachutes to malfunction at the same time.
The sport of skydiving follows exactly the same rules as the aviation industry.
Rigorous and demanding, absolutely no sand is allowed to be mixed in.
When skydiving, the only thing you can rely on is the parachute bag behind you.
The parachute bag you carry must be folded and packed by yourself. Others are strictly prohibited from interfering. Finally, it must be inspected and reviewed by experienced instructors before it can pass.
If an accident occurs while skydiving, there is a 99% chance that you will be shattered to pieces, a 0.9% chance that your body will remain intact, and a 0.1% chance that you will survive.
"clear."
Zhou Hai looked serious, stared at the yellow-green umbrella bag, and wrote down everything Tan Gang said.
"Let me tell you how to deal with the failure of the main and secondary parachutes. The first one is that when the main parachute fails and the secondary parachute fails, first you need to determine the cause of the failure as soon as possible. For example, the secondary parachute fails to expand. You can directly use a paratrooper's knife to cut open the parachute compartment of the backpack and open the parachute."
Tan Gang looked at Zhou Hai who was studying seriously, nodded, and explained in detail word by word: "Although it is possible that the parachute resistance is too small, which will cause you to fall faster and increase the chance of fracture after landing, but it is better than It’s good to be shattered to pieces, but the second option…”
Tan Gang will list every fault situation that has occurred in detail, give the cause and details of each fault, and inform the solution.
Generally speaking, main parachute failure is a very common problem, and simultaneous failure of the main and secondary parachutes is relatively rare.
The former has a normal level of difficulty and a higher chance of survival. You only need to open a normally functioning parachute to survive.
However, the latter dealt with the hell level of difficulty. When encountering a situation where the main and secondary parachutes failed at the same time, they stayed calm and prayed that the cause of the failure was the simplest, and then successfully repaired the secondary parachute.
If you encounter an irreversible failure - congratulations, you have obtained a ticket for reincarnation. You will die miserably, and your choice of heaven and hell will depend on you.
Soldiers enjoy the title of martyr and are awarded posthumous meritorious service based on their merits and performance during their lifetime.
Private skydivers can receive high compensation from insurance companies.
Of course, the premise is that you have to purchase high-value insurance.
Listening quietly to Tan Gang's detailed list of various faults and solutions, Zhou Hai said nothing, absorbing the recorded knowledge like a dry sea.
The sun is shining brightly, and the sun is getting hot and dazzling.
