If you manage to make a successful, retrievable egg deployment, bonus points are awarded, so in order to keep up with the competition, it is almost a must. This event is very similar to Ping Pong Parachute, use some of the ideas gathered on it's wiki page. Another idea is to place the egg in a padded capsule.īacksliders are another idea for a deployment system, but a well built parachute will almost always beat a backslider.
The egg could be suspended by using strings or bungee cords (the strings would have to be pretty tight).
Cushioning can also prevent it from breaking upon impulse or upon hitting the ground.įor cushioning around the egg, suggested materials are:Īdd your suggested materials to this list!
a thin plastic, such as thin drop clothīy attaching the parachute to the egg but not the rocket itself, when it deploys it should separate the egg from the bottle, which the current scoring gives several bonus points for.Ĭushioning around the egg is a good idea in case the parachute fails to deploy. The rocket must have a cone and parachute for the eggs safe landing. Suggested materials for building a parachute are: DESIGN BRIEF: The rocket must have between two and five fins. A 2 to 4 foot diameter should be large enough, although the biggest parachute that will fit in the nose cone is always optimal. A larger parachute is usually better, unless, of course, it is too large. Parachutes work very well as safety devices. It also awards extra points if a module of the launched rocket returns to the ground separate from the main vehicle. This would help reduce the risk of breaking the egg. 3 points if the egg or egg capsule Completely detaches from the rocket.Ī commonly used, but not required device, is a recovery system. 15 points for the recovery of the egg in an intact state. 1 point for every second that the egg is airborne. The recovery system was extremely important because with these rules, a well-built rocket with a broken egg will almost definitely be beaten by a poorly-built rocket with an intact egg. The scoring system for 2010 puts great emphasis on the condition of the egg. 3 fins is a good idea, since it is just as stable as 4 fins but lighter. The bottle must be from a carbonated drink, and if you remove the label(s), you must have them present at checking.įins on the rocket is a commonly used method of maximizing the height the rocket climbs to initially. Depending on the rules, either 1 liter and/or 2 liter bottles may be used.
