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 parachutes symbolize in The Hunger Games?

In the Hunger Games (the games not the book) parachutes symbolize gifts. If you were a tribute in the Games and were sent a parachute, you would get a gift.

In the books however, the parachutes could symbolize many things. But at the end of the series, it would be safe to say that whenever Katniss thinks of the silver parachutes, she will think of her sister Prim (Read book 3 and you will see why).

Why do paratrooper's parachutes have holes in them?

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.

What color were World War 2 parachutes?

White for Allies and yellow for Germans

Some were colored to identify cargo container contents or camoflaged to hide.

Why are there flotation devices under plane seats instead of parachutes?

AnswerCommercial aircraft are not well designed for skydiving. Their normal flight altitude is far too high and engine placement would suck any would-be skydiver right in. Therefore, your best chance or survival would be to assume the crash position and let the pilots land the aircraft on a large body of water. Then, you can escape using your seat cushion (full of beer farts) as a flotation device until help (or sharks) arrive.

What properties of silk that make them suitable material for parachutes?

silk is no longer used for making parachutes. It was a good material before nylon came along, but no parachutes are made from silk anymore. Not for decades.

<><><><>

When it WAS used, it was because it was very light, extremely strong, was not bulky, and could be woven in a very tight weave.

When was the first parachute made?

A parachcute is what you use in the millartary and people use them to go skydiving. And the first parachute made in 1783 by Sebastien Lenormand. And kids can play with parachutes as well.

How do parachutes help skydivers land safely?

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 does the quote 'Minds are like parachutes They only function when open' mean?

An open mind is a mind that is non-judging, open to new thoughts, ways of doing things. That does not see obstacles but opportunities. Before you think about the meaning of this quote, you need to be clear of some terms that seem to be quite obvious, but they aren't:

* What is a parachute? * What is mind? * What is the difference between a closed and an open parachute This brings us to the question: What is an open mind?

A parachute is usually a soft fabric device used to slow the motion of an object through an atmosphere by creating drag.

Mind collectively refers to the aspects of intellect and consciousness manifested as combinations of thought, perception, memory, emotion, will and imagination An open parachute is obviously "in action" or "used" and function, while a parachute is closed when not in use.

The quote "Minds are like parachutes[...]" means that there can be a functional and disfunctional mind (compared to a closed and open parachute). Tommy Deware, who is the author of this quote, states that only an open mind is a mind that is really functioning.

You can make your own sense to what an open mind is (see also previous answer).

Why are there flotation devices under airline seats instead of parachutes?

Most commercial airliners would be so hard to exit with a parachute safely that there is little benefit in providing them. The most likely situation from which escape is feasible is if the plane lands in water. After a water landing (since it is somewhat cushioned) there is a higher potential for survivors that, without life vests, might drown before they could be rescued.

Why don't airplanes themsif not have parachutes on them to help out the emergency landing?

Airplanes do have parachutes to stop a deadly spin. Some light aircraft have them as a safety feature. I can't remember who it was but there was a famous person who died in a plane crash and one of the discussions was why this a/c didn't have a parachute. Parachutes are mainly used when a plan goes into a spin. When the plane stalls, it enters a spin and sometimes it is hard to come out of it. Each type of airplane is different and their propensity to spin is different as well as the ease to recover from it. Some aircraft can enter an inverted spin. Many test aircraft have a parachute installed for this purpose. During Flight Test, the pilot flies the aircraft at extreme speeds and angle of attacks. But the parachute is only used for the experimental flights and then removed. This includes fighter jets.

Is jumping from a plane risky enough without using a chute riddled with holes assuming parachutists dont have holes in their heads whats the reason for the holes in the chutes?

It would seem sensible that parachutes shouldn't even leak air-- but then the air will spill out of one side or another and the parachute will oscillate wildly and be uncontollable. This is what happens. In fact the parachute will fall at a faster rate with NO HOLES. It was found that letting the air out of a center hole "California Blow-hole" improved the performance and handling, and soon it was discovered that letting some air spill out the rear gave the parachutist some directional control. The Russian "Paracommanders" employed a variety of slots and openings to give far greater forward speeds in the 1960's. Followed Rogallo Parawings and then by early "ram-inflated wings" which operate like gliders. None of these were linear developments, many people contributed to the art and science over many years.

Why commercial planes don't have parachute to save life of passengers in case of emergency?

One simple reason: practicability. First of all parachutes are expensive. And having 200 or more parachutes on a fleet of 150+ airplanes would blow airlines' budgets to pieces. Another reason: weight. The weight of all the parachutes would severly limit the capacity of an aircraft. And finally, parachutes are sometimes difficult to operate and would not work with children or people with special needs.

Also, many aircraft accidents happen either immediately after takeoff or just before landing, and there is no time to get all the passengers to put on parachutes (almost all of whom would never have had done so before), get them to the exits and get them out of the airplane, which would also need to be at a sufficient altitude for the parachutes to open safely (before the person wearing the parachute hits the ground). Another consideration is weight and balance. Having all the passengers run to the back of the airplane so they can jump out, when the airplane is already in trouble, may not be the best thing to do (can't jump from the front doors; too many things to hit (i.e., wings, tail, antennas, landing gear, flaps, etc.), and the possibility of ingestion into the engines!) The January 2008 accident involving a British Airways 777 at London-Heathrow is a perfect example of an incident where there was absolutely no time to respond. The flight crew didn't even have time for a 'Mayday' call on the radio, or to tell the passengers and cabin crew to brace for impact. Things can sometimes happen very, very quickly, and in this case the flight crew did an excellent job in getting the airplane on the ground in as few pieces as possible.
