Skydiving is popular in today's world. Some people are professionally involved in this sport, for others, skydiving 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 Kotelnikov Gleb Evgenievich. He was the first to create a backpack device, received a patent for his invention in 1912.
A parachute is a hemisphere constructed of fabric, to which a load or suspension system is attached due to straps. It is designed to slow down and mitigate falls from a height. Used for safe landing of a person or cargo, has several varieties.
How many lines do parachutes have?
This is certainly a very interesting question. There are several types of parachutes, all of them with a different number of lines. There is a main parachute and a spare, landing, army and cargo. Slings are basic andadditional, they are all made of high quality durable fiber, withstand a load (each) up to two hundred kilograms. To answer the question of how many lines parachutes have, you need to consider each instance separately.
Army parachute
The military has been using the same series of parachutes 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 a D-5 military parachute have? There are twenty-eight of them, nine meters each. The parachute itself has the shape of a dome, it is not possible to control it. Land with him how and where you're lucky. This is the only but serious minus of this series.
The D-6 parachute was fired next. It has thirty lines. Twenty-eight are normal, and two are for dome control. They are located in the side sections of the parachute. If you pull these lines, you can turn and deploy the dome in the desired direction. This is a very useful quality if the landing takes place not on a training ground, but in mountainous conditions, forests or in a place where there are water bodies.
Paratrooper parachute
In order for the paratroopers to feel comfortable 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 skydiver. Ease of controldepends on how many lines are in the parachute: the more of them, the easier it is to control.
D-10 has twenty-six main lines: twenty-two four-meter lines and two seven-meter lines, attached to loops in the slots of the dome. There are also twenty-two additional slings located on the outside, their length is three meters, made of a durable cord ShKP-150.
There are also twenty-four additional internal lines. They are attached to additional straps. Two additional ones are attached to the second and fourteenth at once. This is the answer to the question of how many lines are in the airborne parachute. The D-10 is considered one of the safest parachutes in history.
Why do you need a reserve parachute?
A reserve parachute must be kept by a skydiver when jumping. It is designed for emergency deployment 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 the main skydiver, which will lose additional time. If it was not possible to straighten, then the reserve parachute will save the situation. It opens quickly and easily.
To learn how to use a spare tire, you don’t need to go through a lot of training, even a child can handle this task.
How many lines does a reserve parachute have? Usually such parachutes are the same for all major types. These are series 3 and 4. The lines in the spare are arranged in four groups. In eachthere are six lines. We get twenty-four in total. Of course, a reserve parachute is not designed for control, its main task is to open quickly and save a person's life.
What you need to know when skydiving for the first time?
If you are not a conscript soldier in the Airborne Forces and a parachute jump is just a dream, not a military duty, then you should start like training courses. Even if it is decided to jump with an instructor in tandem, training is necessary in order not to harm either yourself or the instructor. He is already so afraid 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 obtaining a medical certificate: a heart attack during a jump is a serious and dangerous thing. But it can happen, because when you jump into the abyss, so much adrenaline splashes out that it will last for a year. Yes, and the fear of jumping can also lead to sad consequences if the heart is naughty. The pressure should also be the same as when entering the space forces. If you are overweight, then you should also consult a doctor whether or not to jump.
If you are under the age of eighteen, written permission to 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 you go to the parachute for a kilometer. People with mental disorders are not allowed to jump, after recent surgeries, withdiseases of the musculoskeletal system, with a disease of the respiratory tract.
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. Do not drink alcohol beforehand. It is clear that the joy rolls over, but it is better to celebrate this event after the event, 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 idea altogether. And good luck to everyone who passed the medical examination!
