Dual Egg Lofting Altitude
Dual Egg Lofting Altitude Competition comprises five events open to model rockets that carry, as a totally enclosed payload, two raw USDA Large hen’s eggs, each with a mass of no less than 57 grams and no more than 63 grams, and measuring no more than 45 millimeters in diameter. If the model is staged, the eggs must be enclosed in the uppermost stage of the model. The purpose of this competition is to carry an exceedingly fragile payload to as high an altitude as possible and to recover the payload without damage. The eggs are intended to simulate (in miniature) astronauts, who must be properly cushioned and restrained to withstand the forces of acceleration and the shock of landing. No material may be affixed to the eggs (e.g., glue or tape).
The Safety Check Officer or other official shall provide the eggs to each contestant presenting his/her entry for pre-launch safety check. Each egg shall be numbered, and the numbers shall be recorded on the contestant’s flight card. A contestant shall not be required to use an egg that has been previously lofted by another contestant. The Safety Check Officer shall also perform an inspection of the recovery system to insure that it is sufficient to safely recover the model, and will perform properly.
Following the flight, the contestant shall present his/her entry as recovered and, in the presence of an official, shall remove the eggs. The official shall determine the extent of damage to the eggs. If the official cannot examine the eggs, the entry shall be disqualified. If the contestant removes the eggs in the absence of officials, or breaks either egg in the process of removing them from the model, the entry shall be disqualified. If the shell of any egg is broken or cracked upon removal of the egg, the entry shall be disqualified. All entries must comply with the provisions of Rule 16.7.
This competition is divided into classes based on the permissible total impulse of the motor(s). The following classes of Dual Egg Lofting Altitude Competition are established:
|Motor Class||Weighting Factor|
If the portion of the model containing the eggs cannot be returned to the officials, the entry shall be disqualified. Rule 10.4 does not apply.
