Democratic Schools meeting at Arad:
Apr. 13-15, 2005 |
| |
The event was divided into 3 parts:
|
| 1. |
Rocket party - every participant gets to build and launch a Skewer Design.
|
| 2. |
Setting a Target - Teams and individuals attempt to build a recovery system that will keep the rocket in the air as long as possible.
|
| 3. |
Measuring results - Rockets from part 2 are tested and improved.
|
|
|

As expected, all teams used a garbage bag parachute hidden under a cover that was designed to fall off at apogee. Some covers got stuck on the rocket during launch and never fell off, others fell during ascend and the parachute separated from the rocket.
Due to the robustness of the "Skewer Design" rocket, all teams got a chance to improve the design based on the failed attempts.
The launches were done at 6 ATM (87 psi), the best time was 11.8 seconds from launch back to ground. The pictures on this page show some of the designs and pictures taken during descent.
