Gen 0-S

The Gen 0-S parachute systems were simple models constructed with household items such as jars and left over springs. These models were used to determine the feasibility of a spring powered parachute system.

  • Time in service: September 2018
  • Tests performed: 1
  • Problems: no release mechanism, small size
  • Status: retired

Gen 1-S

Constructed with cardboard and sprinkler parts, the Gen 1-S parachute system was a simple proof of concept model used early in the development process. The Gen 1-S was in use for a few days and during that time performed only a couple of tests. These tests revealed the need for a better release mechanism. Most of the Gen 1-S was repurposed into the Gen 2-S.

  • Time in service: September 2018
  • Tests performed: 1
  • Problems: under powered springs, no release mechanism
  • Status: parts used to build Gen 2-S

Gen 2-S

The Gen 2-S improved on the Gen 1-S by adding a simple, 3D printed, release mechanism. This mechanism, made the system easier to use and helped guide the design for future generations of this system. After a few tests it was replaced by the Gen 3-S.

  • Time in service: November 2018
  • Tests performed: 1
  • Problems: under powered springs
  • Status: retired

Gen 3-S

The Gen 3-S marked many firsts for the parachute system. It was the first to be made of fully 3D printed parts and to utilize purpose bought springs. The Gen 3-S also used a servo powered release mechanism. If it were not for the numerous problems that were mostly fixed in the Gen 4-S, the Gen 3-S would have been the first parachute system to fly.

  • Time in service: November 2018
  • Tests performed: ~4
  • Problems: short springs, week hinges, faulty release mechanism, hard to pack chute
  • Status: parts reused

Gen 4-S

The Gen 4-S was similar in many ways to the Gen 3-S, it was simply a more refined version. The Gen 4-S solved most of the Gen 3-S’s issues such as week hinges and bad servo placement. Unfortunately, the Gen-4-S did not fix the issues with release mechanism power, which lead to this method of parachute deployment being retired entirely.

  • Time in service: March-May 2019
  • Tests performed: ~3
  • Problems: faulty release mechanism, hard to pack chute
  • Status: retired
