Parachutes
Parachutes are devices most commonly used in skydiving. They are sections of fabric, usually made from nylon, that helps to slow a person or object when dropped form a high open location.

What do the military use parachutes for?
Asked by Wiki User
to travel downwards beneath the gravity of the atmosphere and break a persons immediate fall.
How do parachutes work for a water rocket?
Asked by Wiki User
the parachutes slow down the rocket so it doesnt smash into peices when it hits the ground
Do you get wet when you parachute?
Asked by Wiki User
if you pee your pants: yes if your bladder can control itself: no
Did Japanese Kamikaze pilots wear parachutes?
Asked by Wiki User
Most did not. Some were sealed in their planes and only had enough fuel for their one-way trip to the US fleet. They were suicide pilots, and their only means of attack was to crash their aircraft into US ships.
Why were parachutes made from silk?
Asked by Wiki User
Silk is very strong and resistant to tearing. Lightweight, silk is not a significant burden on aircraft, and can be carried, for example, on jumper's backs. It is resistant to moths, mildew and mold.
How do parachutes help skydivers land safely?
Asked by Wiki User
The large area of a parachute canopy increases wind resistance greatly, slowing the fall, and permitting the skydiver to steer towards a landing spot.
when the skydiver jumps out of the plane his weight makes him accelerate, soon the air resistance balances out the forces, but his terminal velocity is too great for him to land safely, son he opens a parachute, the parachute makes the air resistance greater, as it has a larger surface area. soon the air resistance, and the weight are balanced, but now the parachutist is going slowly enough to land safely, and not kill himself.
air resistance increases greatly when the parachute is opened and that results in the deceleration of the skydiver; As a result, The skydiver will reach a speed appropriate for landing safely.
The canopy (parachute) has multiple cells. The nose (front) of the canopy is open but the back is closed which pressurises the canopy during forward flight and thus maintains the aerodynamic shape of the canopy which generates lift.
The slider, a square shaped fabric with four round gommits in the corners separates the lines, the lines from the nose to the front and those from the steering brake line to the rear. The slider slows the opening down so that the deceleration is controlled.
The canopy is controlled by pulling on the toggles, the left toggle for a left turn and visa versa.
A final turn is made relatively close to the ground so that the landing is into wind, thus reducing the ground speed and just prior to landing, the skydiver pulls down on both toggles to induce a flare which slows and stalls the canopy for a generally soft stand up landing.
By creating a large surface that has a high wind resistance, a parachute slows the fall of a sky diver- and permits them to guide the direction of their descent. Falling slower = good.
i think that it balances out the force of gravity pulling you down with air resistance so you reach the ground at a sensible speed hence not getting hurt.
What are parachutes made out of?
Asked by Wiki User
There are a range of parachute manufacturers based around the world. It is common for manufacturers to be separated into parachutes and containers. The container is the 'ruck-sack harness' which holds the folded parachute.
Once you have placed an order, the parachute will be cut to size of a big laser cutting table. Then the pieces are assembled and checked by riggers.
Who used parachutes?
Asked by Wiki User
Anyone who goes Sky Diving or any activity that requires you to jump out of anything that is too high to jump off without one.
Why ropes made of nylon used in elevators and cranes?
Asked by Wiki User
Nylon fibre was strong, elastic and light. It was lustrous and easy to wash. So the ropes are made up of nylon. Parachutes also made up of nylon.
Why was the parachute created?
Asked by Wiki User
Initially skydiving was invented out of parachuting as a means to save an aeronauts life in case their balloon failed at altitude. The idea was not to freefall, but simply to return back to terra firma without injury.
It was thought that the human body could not survive freefall and that you would simply blackout. In the early 20th century, some brave souls invented skydiving with a parachute that could be packed into a harness and container. Over a short period of time, this myth was busted and in fact 'skydivers' realised that skydiving was actually fun, thus the sport was born.
What is the importance of parachutes?
Asked by Wiki User
because they slow down the momentum of stuff
What material do they use in parachutes?
Asked by Wiki User
Parachutes are most commonly made of nylon. The term "ripstop nylon" used to be applied to the construction materials, but any more, it is "nylon" from which almost all chutes are made. During WWII parachutes were made of silk as nylon wasn't around yet.
Why do people use parachute?
Asked by Wiki User
Friction. Same reason why a bowling ball falls faster than a feather. It's not about weight, it's about surface area as compared to weight. A fat skydiver will fall faster than a 110 lb girl in freefall for the same reason.
Who invented the parachute?
Asked by Wiki User
Leonardo da Vinci created designs of a very complicated parachute in 1485. This is only slightly later than the earliest mention or depiction of one, an anonymous design involving a long piece of cloth with handholds at each end, where extra security was provided by four ropes or cords attached to the parachute and to the user's belt.
French inventor Louis-Sébastien Lenormand was the first to jump using a parachute in 1783.
Stefan Banic, a Slovak inventor, constructed a prototype of a modern parachute in 1913
Why do paratrooper's parachutes have holes in them?
Asked by Wiki User
A parachute works by trapping air underneath, but when the air is trapped the pressure increases and some of the air has to escape. If there were no hole in the center of a round parachute, such as the military 'chutes used in WW2, the excess air would have nowhere to escape except under the edges of the 'chute, which would cause increasingly violent oscillation and quickly the collapse of the 'chute, which would drop the parachutist to the ground at high speed and kill him. The central hole allows a controlled release of the air pressure in the 'chute, preventing oscillation and the collapse of the 'chute.
