Why does a parachute allow a paratrooper to land accurately

After reaching the ground from a height of several thousand meters, there is no straight channel. However, a good paratrooper can maneuver a parachute, one moment to the left, another to the right, and land accurately on the predetermined place. Is there a steering wheel installed on the parachute?

This problem was taken into account when parachutes were made, so each line was numbered. And a short rope is sewn at the lower end of the first to the last paracord, and a control rod is tied to the short rope. When the paratrooper needs to turn to the left, he pulls down the left control stick; And when turning to the right, pull down the right stick.

Why does the parachute turn when you pull the control stick? In fact, there is a special exhaust port on the canopy, and the two sides of the exhaust port are connected to the first and last lines. When the canopy is opened, the air density inside will be greater than the air density outside, creating a pressure difference between the inside and outside.

When the paratrooper needs to turn to the left, he only needs to pull down the left control stick to drive the parachute rope to move downward, so that the parachute on the left side of the exhaust port is recessed inward, and the parachute on the right side of the exhaust port is relatively convex, and the air in the parachute will also be discharged to the left rear through the exhaust port, and at the same time produce a force in the opposite direction to push the parachute to the right front, so that the parachute can turn to the left. In the same way, pull down the right lever so that the air in the parachute is discharged to the right rear of the exhaust port, and then push the parachute to the left front, and the parachute will drive the paratrooper to the right.

A ( ) parachute:

One parachute.

In the process of falling at a uniform speed in the air, the mass remains the same, the speed does not change, and the kinetic energy does not change; As the height decreases, the gravitational potential energy decreases.

As the area of the parachute increases, the drag on the parachute descent increases, the descent speed decreases, and the flight duration is extended; As the area of the parachute decreases, the drag experienced by the parachute during descent decreases, the descent speed increases, and the flight time is shortened.

The spacecraft parachute opens sequentially from the guide parachute, the parachute, and the main parachute.

1. The guide umbrella is the smallest and the first one is opened.

The conical strip parachute is a guide parachute, the first to open, mainly to pull the parachute out of the canopy cabin barrel, so it bears a lot of force. Its material texture is also very strong and stable.

2. After the parachute is opened, the speed can be reduced to 90 meters per second.

The parachute, also known as the conical strip parachute, is the second to open. Its main function is to decelerate, that is, from 200 meters per second to about 90 meters per second, to ensure that the main wing is open.

3. The main umbrella has 1200 square meters and the speed drops to 7 8 meters per second.

The scientific name of the main umbrella is Huanfan Parachute, and the whole umbrella has 1,200 square meters, which is the largest parachute among all spacecraft in China.

The parachute is a kind of aerodynamic reducer that uses air resistance, it relies on the movement relative to the air to inflate, and in the early days, some people grabbed the umbrella with their hands and jumped from the house, which is the original face of the rain umbrella. A modern parachute is an aviation tool that allows a person or object to safely land from the air to the ground. Mainly made of soft fabrics.

It is used for airborne combat training, life-saving training of aerospace personnel, training and competitions and performances of parachutists, airdrop materials, and aircraft, which are suitable for aviation, aerospace and other fields. After the parachute reaches the ground from a height of several thousand meters, there is no straight channel, which is why the paratroopers are able to land accurately. However, a good parachute stool soldier in a town can maneuver a parachute to land accurately on a predetermined spot for a while, left and right.

Is the steering wheel mounted on a parachute? This problem was already taken into account when creating parachutes. A short rope is sewn to the bottom of the first to the last paracord, and the rope is tied to the rope with a handle, so that a rope can be pulled off the top.

The air inside the canopy will be denser than the outside, so the air pressure difference between the inside and outside will form. Push the parachute to the left front, and the parachute will drive the paratrooper to the right.

A parachute is a kind of pneumatic reducer that uses air resistance to inflate air by relative air movement. The reserved airway of the parachute In the early days, someone jumped out of the house with an umbrella, which was the prototype of the reserved airway of the parachute. Modern parachutes are aviation tools for the safe landing of people or objects from the air to the ground.

It is mainly made of flexible fabrics. It is airborne combat training, life-saving training for astronauts, training for parachutists, competitions and performances, airdrop materials, first-class aircraft and other equipment and equipment. The paratroopers were able to land accurately because there was no direct channel after reaching the ground from a height of several thousand meters.

But a good paratrooper can maneuver a parachute, turn left and right in a flash, and land accurately at the specified place. Is there a steering wheel on an umbrella? When making parachutes, this problem was already taken into account, so a short rope was sewn at the lower end of each parachute line, and there was also a control rod on it.

and tie the short rope to the lower end of the first to the last paracord. At the lower end of the first to the last paracord, a lever is attached. When the paratrooper needs to turn left, pull down the left control stick; And when turning right, pull down the right lever

In fact, the canopy has a special exhaust port, and the two sides of the exhaust port are connected with the first and last parachute lines, forming a density of air inside and outside that is lower than that of the outside, thus forming a pressure difference between the inside and outside air. And when the paratrooper needs to turn to the left, he only needs to pull down the left control stick to drive the parachute line down. This thus tilts the canopy on the left side of the exhaust port downward.

The air inside the umbrella is also expelled to the left rear through the air outlet, creating a reverse force that pushes the suit to the left front, so the parachute can be turned to the left. In the same way, pull down the right control button to let the air in the umbrella suit escape from the right rear of the exhaust port in the umbrella, and then push the umbrella suit to the left front, and the umbrella will drive the paratrooper to turn right.

Umbrellas cannot be used as parachutes because they are designed and used in different scenarios. Umbrellas are designed to provide shelter and rain protection for the user. They are usually made of lightweight materials, such as plastic or light metal, and are supplied with a thin, soft umbrella cloth.

When umbrellas are used for shelter from the rain, the user simply holds them and opens them gently. They don't need to bear extra weight or force. Similarly, on rainy days, the wind is usually not very strong, so a regular umbrella is sufficient at that time.

In contrast, parachutes are designed to support the safe landing of the human body from high altitudes. Parachutes need to withstand more weight and pressure, so they are often made of stronger and more durable materials such as nylon and steel wire. The parachute is also more complex in structure and is equipped with multiple ropes, straps, and air vents to control the speed of the descent.

The use of parachutes also requires professional training to ensure that the user is properly donned and used.

In addition, due to the different sizes and shapes of umbrellas, even if they are used as temporary parachutes, they do not provide a suitable support area. This can cause the user to descend at high speeds, resulting in serious injury or death. In addition, the umbrella is designed to open and close in such a way as a parachute control and braking requirement that it lacks the necessary landing equipment for agitation, such as a subparachute, backpack, helmet, protective clothing, etc.

All in all, umbrellas and parachutes are two different pieces of equipment, each with its own purpose. Umbrellas can be used to protect against the rain when it rains, but don't try to use them as temporary parachutes, which can have serious consequences. <>

Summary. Hello, dear, the parachute is made in the shape of an umbrella because the parachute uses the resistance of the air to reduce the descent speed. Use a relatively large umbrella surface to increase the resistance when the free fall is descending, reduce the speed when descending, and make the speed of the person descending to the ground become the speed that the human body can bear, that is, the speed of the human body falling and the momentum formed by the body weight is what the human body, especially the legs, can withstand and overcome, so as to avoid being disabled due to excessive speed, and even endangering life!

Hello, dear, the parachute is made into a parachute type because the parachute uses the resistance of the air to reduce the descent speed. Use a relatively large umbrella surface to increase the resistance of the free fall body, reduce the speed of the fall, so that the speed of the human body can bear the speed of the human body, that is, the speed of the human body descending and the momentum formed by the weight is the human body, especially the legs, can withstand and overcome, to avoid falling and disabling due to too high speed, and even endangering life!

The main components of the parachute are the parachute, the guide parachute, the parachute line, the harness system, the parachute opening parts and the Sun Chiyou parachute bag. It is composed of parachute silk (silk, cotton, and nylon fabrics were used in the early days), textile materials such as parachute ropes, parachute belts and parachute threads, as well as some metal parts and rubber and plastic parts

In layman's terms, it's the one that slows down as the sky falls! For example, a hole in the top of an umbrella in life is equivalent to a small parachute!

It is mainly made of breathable flexible fabric and can be folded and packaged in an umbrella bag or umbrella box, and is a kind of pneumatic reducer that moves relative to the air when working, inflats, and slows down and stabilizes people or objects. Usually put the landing.

A parachute is an aviation tool that uses air resistance to make people or things safely land from the air to the ground by relying on an deployable aerodynamic reducer that is inflated relative to air movement. It is mainly made of flexible fabrics. It is the combat and training of the Airborne Forces, the life-saving and training of aerospace personnel, the training, competition and performance of parachutists, the airdrop of materials, and the equipment and equipment of the first aircraft.
