Super-Roc Duration rules
Super-Roc Duration Competition comprises ten events open to single-staged model rockets whose body length is no less than the minimum allowed for the classes of the event. The purpose of this competition is to achieve the greatest duration possible with the longest rocket possible without impairing the structural integrity of the rocket.
33.2 Structural Failure
An entry that comes apart, bends so as to crimp the body, or has a similar structural failure prior to ejection shall be disqualified.
Entries with bodies or significant structural parts made from hard or potentially unsafe material (e.g., hardwood doweling or fiberglass shaft) shall not be allowed, under the provisions of Rule 1.1.
Super-Roc Duration Competition shall be scored as follows: the length in centimeters of the model, as measured from the tip of the nose cone to the end of the motor nozzle, up to the maximum length for that category, shall be awarded as static points. If the model has more than one motor, the length shall be measured to the motor nozzle closest to the tip of the nose cone. No additional points are awarded for any length beyond the maximum. The achieved duration of the model in seconds shall be awarded as flight points. The static points and flight points thus obtained shall be multiplied to determine the total points for each flight. The contestant achieving the highest score is the winner. When posting, printing, or maintaining contest results or performance records, the model’s time in seconds must be shown with its composite score.
This competition is divided into classes based on the permissible total impulse of the motor(s). The following classes of Super-Roc Duration Competition are established:
|Motor Class||Minimum Length
