2. EARLY RENAISSANCE
PARACHUTES
BY 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.

3. 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.
4. 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
5. 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

6. 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.
7. • 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.

8. 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).
9. 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.
10. 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.
11. 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.

12. 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.

13. 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.
14. • 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.
15. They slow down
They are
vehicles such as
things
dragsters and
that stop
more moving
or slow
objects.
