Egg Lofting Duration rules
Egg Lofting Duration Competition comprises six events open to single-staged model rockets that carry, as a totally enclosed payload, one raw USDA Large hen’s egg, with a mass of no less than 57 grams and no more than 63 grams; and measuring no more than 45 millimeters in diameter. The purpose of this competition is to carry an exceedingly fragile payload for as long a time as possible and to recover the payload without damage. The egg is intended to simulate (in miniature) an astronaut, 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 egg (e.g., glue or tape).
The Safety Check Officer or other official shall provide the egg to each contestant presenting his/her entry for pre-launch safety check. Each egg shall be numbered, and that number shall be recorded on the contestant’s flight card. A contestant shall not be required to use an egg that has been previously flown by another contestant.
Following the flight, the contestant shall present his/her entry as recovered and, in the presence of an official, shall remove the egg. The official shall determine the extent of damage to the egg. If the official cannot examine the egg, the entry will be disqualified. If the contestant removes the egg in the absence of officials, or breaks the egg in the process of removing it from the model, the entry shall be disqualified. If the shell of the egg is broken or cracked, the entry shall be disqualified. Any model that cannot be returned to the officials shall be disqualified. Rule 10.4 does not apply. All entries must comply with Rule 16.7 (no catching of models is allowed for official flights).
This competition is divided into classes based on the permissible total impulse of the motor(s). The following classes of Egg Lofting Duration Competition are established:
|Motor Class||Weighting Factor|
Egg Lofting Duration shall be scored as follows: The contestant whose model achieves the longest duration for a single flight is the winner.
