THE MAKING PROCESS

Parachutes

The process of making the parachutes is described in the following steps:

• testing the optimal material and shape of parachutes (plastic trash bag, cotton, sewed plastic),
• calculate and estimate the weight of the load,
• making an appropriate stencil for the parachute gores,
• the calculations from the following web pages can be used:

• the plastic trash bag parachute with the diameter 1,5 m:
  • 8 large trash bags (one for each gore),
  • making a stencil,
  • binding gores together by using the stencil, a sewing machine or duct tape,
  • attaching 8 strings, each 2,5 m long, on each gore,
  • making a hole at the top of the parachute (it helps open the parachute faster and stabilize the parachute during the fall).
