EARLY RENAISSANCE PARACHUTESBY KAYLA AND CAPPY

The oldest parachute design was from the 1470’s. The picture shows a free-hanging man clutching a cross bar frame attached to a conical canopy. As a safety measure, four straps run from the ends of rods to a waist-belt. It is not known whether the Italian inventor was influenced by an earlier design but he may have learnt about the idea through the intensive oral communication. Here, the scale of the parachute is in a more favorable proportion to the weight of the jumper.

BY KAYLA AND CAPPY

On 1st of march USA army captain Albert Leo Stevens made the first parachute jump in 1911.

During the war they Jumped out of planes with parachutes to get a better location.

1927 people use to parachute to land behind the enemies line and attack the enemies from the behind

and the front.And the word parachute come from the French.

They also can do a surprise attack at night.

Parachutes

The general characteristic of the ram-air is the lift and airflow of a

parachute ,it creates the lift with a pocket of air

rogallo wind and other types

•Sky diving has experimented with the Rogallo wing These were nearly always an attempt to increase the forward speed and reduce the landing speed

General Charactaristics!

Parachutes are made to open softly. Fast opening or deployment was an early problem

with ram-air designs. The first change that slows the deployment of a ram-air is a slider, a small rectangle of fabric with a metal ring near each corner. Four collections of lines go through the

metal rings to the risers (risers are strips of webbing joining the harness and the rigging

lines of a parachute). This reduces the speed at which the fabric can open and inflate.

At the same time, the overall design of a parachute still has control over speed. Modern

parachutes' deployment speeds vary considerably. Most modern parachutes open

comfortably, but individual skydivers may prefer harsher deployment.

On rare occasions deployment can even be so rapid that the sky diver suffers bruising, injury

or death.

• The Safety!!

• A parachute can malfunction in several different ways. It has to be safe for people to use, or it can cause serious injury. The parachute is packed carefully and in a certain way, to make sure it comes out the right way without breaking or ripping. Sometimes the parachute does not come out of the baggage, making it hard to land softly, causing major injury and sometimes even death.

Round and Cruciform

Round parachutes are purely a drag device and are used in military, emergency and cargo applications. These are large

dome-shaped canopies made from a single layer of triangular cloth gores. Some skydivers call them jellyfish chutes because of the resemblance. Modern sports parachutists rarely use this type.

The round parachute were simple flat circulars. These early parachutes suffered from stability caused by oscillations.

Cruciform

The unique design characteristics of cruciform parachutes decreases oscillation and violent turns during decent. This

technology will be used by the US army as it replaces its current T-10 parachutes under a program called ATPS (Advanced Tactical

Parachute System).

The history of skydiving starts with Andre Jacques Garnerin who made successful parachute jumps from hot air balloons in 1797. The Military developed parachuting technology as a way to save aircrews from emergencies. You can go skydiving in Auckland, Taupo and Rotorua.

The modern parachute was inverted in the 18th century by Louis Sebastren Lenornand in France. Who made the first recorded public jump in 1783. Lenornand also sketched his device beforehand. Two years later in 1785 Lenornand invented the word parachute.

Different types of parachutes

• A drogue parachute is a parachute designed to slow down a rapidly moving object.

• The hot air balloon is the oldest successful human carrying device.

Deployment

Reserve parachute usually have a ripcord deployment system which was first designed by Theodore Moscicki, but first most modern main parachute used by sports parachute use a form of hand deployment pilot chute. Only the hand-deployed pilot chute maybe collapsed automatically after deployment by-a kill line reducing the in-flight drag of the pilot chute on the main canopy.

Parachute records By: Jordy & Shareece

On 16th august 1960 Joseph Kittinger has a world record for doing the biggest parachute jump. He jumped from 102,800 feet from a balloon and was falling for 4 minutes and 36 seconds. After that he was put in the world records book.

• The first parachute was made out of strong cloth then they made them out of silk now days they make them out of nylon. The rope is nylon Kern mantle rope.

Drogue parachutes

They are things that

stop or slow down

the vehicle.

They slow down vehicles such as dragsters and more moving objects.

It was invented by Giovanni Agusta in 1911.They are needed on any vehicles that reach up to 240 kilometers an hour(150 miles an hour)
