Parachute class research

  1. 1. Parachute Week• Partner - Student research using Wikipedia
  2. 2. EARLY RENAISSANCE PARACHUTES BY KAYLA AND CAPPYThe oldest parachute design was from the 1470’s. The pictureshows a free-hanging man clutching a cross bar frame attachedto a conical canopy. As a safety measure, four straps run fromthe ends of rods to a waist-belt. It is not known whether theItalian inventor was influenced by an earlier design but he mayhave learnt about the idea through the intensive oralcommunication. Here, the scale of the parachute is in a morefavorable proportion to the weight of the jumper.BY KAYLA AND CAPPY
  3. 3. On 1st of march USA army captain Albert LeoStevens 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. 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. 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 B y C a ll u m a n d D e n z e l
  6. 6. General Charactaristics! Parachutes are made to open softly. Fast opening or deployment was an early problem with ram-air designs. The firstchange 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 ofwebbing 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 speedsvary considerably. Most modern parachutes open comfortably, but individual skydivers may prefer harsher deployment.On rare occasions deployment can even beso rapid that the sky diver suffers bruising, injury or death.
  7. 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.• By Selena and Madison!!
  8. 8. Round and Cruciform Round parachutes are purely a drag device and are used inmilitary, 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 sportsparachutists rarely use this type. The round parachute weresimple flat circulars. These early parachutes suffered from stability caused by oscillations. CruciformThe unique design characteristics of cruciform parachutesdecreases 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. 9. The history of skydiving starts with Andre Jacques Garnerin who madesuccessful parachute jumps from hot air balloons in 1797. The Militarydeveloped parachuting technology as a way to save aircrews fromemergencies. You can go skydiving in Auckland, Taupo and Rotorua.
  10. 10. The modern parachute was inverted in the 18th century by LouisSebastren Lenornand in France. Who made the first recordedpublic jump in 1783. Lenornand also sketched his devicebeforehand. Two years later in 1785 Lenornand invented the wordparachute.
  11. 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.By Khayla and Mya;)
  12. 12. DeploymentReserve 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.Done by: Illandra & Britney
  13. 13. Parachute records By: Jordy & ShareeceOn 16th august 1960 Joseph Kittinger has a worldrecord for doing the biggest parachute jump. Hejumped from 102,800 feet from a balloon and wasfalling for 4 minutes and 36 seconds. After that hewas put in the world records book.
  14. 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.
