- 25.1 Scope
- Superroc Altitude comprises ten events open to single-stage model rockets whose body length is no less than the minimum specified in Rule 25.6 – Classes for the motor class of the event. The purpose of this competition is to achieve the highest altitude with the longest possible rocket, while avoiding structural failure of the airframe.
- 25.2 Structural Failure
- An entry that separates, folds, or has a structural failure prior to ejection must be disqualified.
- 25.3 Separation
- An entry is allowed to separate into two or more unattached parts after ejection, provided that each part satisfies the provisions of Rule 3.5 – Reusability.
- 25.4 Safety
- Entries must satisfy the provisions of Rule 1.2 – Model Rocket.
- 25.5 Scoring
- Superroc Altitude must be scored as follows: the length of an entry to the nearest centimeter, as measured from the tip of the nose cone to the end of the motor nozzle, up to the maximum length for that category, must be awarded as static points. If an entry has more than one motor, the length must 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 altitude of the model measured in meters, must be awarded as flight points. The static points and flight points obtained must be multiplied to determine the score. The competitor achieving the highest score must be declared the winner. When posting, printing, or maintaining contest results or performance records, an entry’s altitude in meters must be shown with its composite score.
- 25.6 Classes
- This event is divided into classes based on the permissible total impulse of the motor(s). The following classes of Superroc Altitude are established:
Motor Class Minium Length (cm) Maximum Length (cm) 1/8A 12 25 1/4A 25 50 1/2A 50 100 A 75 150 B 100 200 C 125 250 D 150 300 E 175 350 F 200 400 G 225 450
