Super-Roc XL Altitude

« Provisional Events

P24.1 Scope

Super-Roc XL Altitude Competition comprises nine events open to single staged model rockets whose length and circumference are no less than the minimum values allowed for the classes of the event. The purpose of this competition is to achieve the greatest altitude possible with the largest rocket possible without impairing the structural integrity of the rocket.

P24.2 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.

P24.3 Separation

The model is allowed to separate into two or more unattached parts after ejection, provided that each part conforms to the provisions of Rule 3.5.

P24.4 Construction

Entries with bodies or significant structural parts made from hard or potentially unsafe material (e.g., hardwood doweling or fiberglass shafts) shall not be allowed, under the provisions of Rule 1.1.

P24.5 Static Points

Static points shall be calculated as length (in centimeters) multiplied by circumference (in millimeters). Length and circumference will be measured for the longest constant diameter section of cylindrical tubing used in the vehicle. Multiple adjacent tubes of the same diameter joined with coupler(s) shall count as a single section. Length and circumference must meet or exceed the minimum values for the event categories. No additional length or circumference points are awarded for values exceeding the maximum values.

P24.6 Scoring

Super-Roc XL Altitude Competition shall be scored as follows: the static points shall be multiplied by the altitude (in meters) to determine the score. The contestant achieving the highest score shall be declared the winner.

P24.7 Classes

This competition is divided into classes based on the permissible total impulse of the motor(s). The following classes of Super-Roc XL Altitude Competition are established:
