Skydiving is popular in the modern world. Some people are professionally involved in this sport, for others a parachute jump is a way to tickle your nerves and get a dose of adrenaline. Has anyone wondered how many lines parachutes have?
What is a parachute?
A parachute is a brilliant and simple invention of an engineer from St. Petersburg Gleb Evgenyevich Kotelnikov. He was the first to create a knapsack device, received a patent for his invention in nineteen hundred and twelve.
A parachute is a hemisphere made of fabric, to which a load or suspension system is attached by means of slings. It is intended to slow down and mitigate a fall from a height. It is used for safe landing of a person or cargo, has several varieties.
How many lines do parachutes have?
This, of course, is a very interesting question. There are several types of parachutes, all of them with different numbers of lines. There is a main parachute and a spare, landing, army and cargo. Slings are basic and optional, they are all made of high quality durable fiber, withstand a load (each) of up to two hundred kilograms. To answer the question of how many lines the parachutes have, you need to consider each instance individually.
Army parachute
The armed forces have been using parachutes of the same series for many years. From the sixties to the present day these are D-5 and D-6 parachutes. They differ in size, weight and number of lines.
How many lines does the D-5 army parachute have? There are twenty eight, nine meters each. The parachute itself has the shape of a dome; there is no way to control it. Land with him how and where you are lucky. This is the only, but serious minus of this series.
Following released the parachute D-6. He has thirty slings. Twenty-eight are conventional, and two are for controlling the dome. They are located in the side sections of the parachute. If you pull these slings, you can turn and unfold the dome in the right direction. This is a very useful quality if the landing is not at the training ground, but in the mountains, forests or in a place where there are water bodies.
Paratrooper parachute
In order for the paratroopers to feel calm during the jump, they are provided with D-10 series parachutes. This is an improved version of the D-6. It has the shape of a squash, the size of the dome is one hundred square meters! This parachute can be easily controlled even by a novice parachutist. The ease of control depends on how many lines in the landing parachute: the more there are, the easier the control.
D-10 has twenty-six main slings: twenty-two four-meter slings and two seven-meter slings attached to the loops in the crevices of the dome. There are also twenty-two additional slings located on the outside, their length is three meters, made of durable ShKP-150 cord.
There are twenty-four additional inner slings. They are attached to additional slings. Two additional ones are attached to the second and fourteenth at once. This is the answer to the question of how many lines in an airborne parachute. The D-10 is considered one of the safest parachutes in history.
Why do I need a backup parachute?
A reserve parachute must be with the paratrooper when jumping. It is intended for emergency disclosure when the main one does not open or if it is twisted. In such a situation, it doesn’t matter whether the canopy is controlled or not, how many lines the parachutes have - none of the additional ones will help. Of course, an experienced skydiver will first try to straighten out the main one, which will lose extra time. If it was not possible to straighten, the emergency parachute will save the situation. It opens quickly and easily.
In order to learn how to use the reserve, you do not need to go through many trainings, even a child will cope with this task.
How many lines does a reserve parachute have? Typically, such parachutes are the same for all major species. These are series 3 and 4. Slings in the spare are arranged in four groups. Each has six lines. In total, we get twenty-four. Of course, the reserve parachute is not designed for control, its main task is to quickly open up and save a person’s life.
What you need to know when you parachute for the first time?
If you are not a soldier of military service in the Airborne Forces and a parachute jump is just a dream, not a military duty, then it’s worth starting with training courses. Even if it is decided to jump with the instructor in tandem, training is necessary in order not to harm either himself or the instructor. He is already scared to jump with a person, and even answer for someone's life. Such courses cost from three thousand rubles - it depends on the company providing these services.
Before you go to the club, take care of getting a medical certificate: a heart attack during a jump is a serious and dangerous thing. And it can happen, because when you jump into the abyss so much adrenaline spills out that enough for a year. And the fear of a jump can also lead to sad consequences if a heart is naughty. Pressure should also be the same as when entering the space forces. If there is excess weight, then it is also worth consulting with a doctor whether or not to jump.
If you have not reached the age of eighteen, a written permission to take the jump from your parents will come in handy. Do not forget to warn them what you are going to do, without their written consent, the instructor will not let a parachute per kilometer. People with mental disorders, after recently undergone operations, with diseases of the musculoskeletal system, with respiratory tract disease are not allowed to jump.
If your weight is more than one hundred and twenty kilograms, then you will be denied a tandem jump. Weight less than forty-five kilograms is a contraindication for a single jump. Pregnant women are also not allowed. First, calmly take out the child, do not hide your position from the instructor in order to make the jump.
Skydiving is the dream of many. In no case before him do not drink alcohol. It is clear that the joy goes through the roof, but it is better to mark this event after the commission, especially since you will not be allowed to jump with the smell of alcohol. And if you decide to drink so that it is not scary, then it is better to refrain from this undertaking altogether. And everyone who underwent a physical examination - good luck!
