- P41.1 Scope
-
Super-Roc XL Duration Competition comprises nine events open to single staged model rockets whose length and circumference are 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 largest rocket possible without impairing the structural integrity of the rocket.
- P41.2 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.
- P41.3 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.
- P41.4 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 be meet or exceed the minimum values for the event
categories. No additional length or circumference points are awarded for values exceeding the maximum values.
- P41.5 Scoring
-
Super-Roc XL Duration Competition shall be scored as follows: the static points shall be multiplied by the duration (in seconds) to determine
the score. The contestant achieving the highest score shall be declared the winner.
- P41.6 Classes
-
This competition is divided into classes based on the permissible total impulse of the motor(s). The following classes of Super-Roc XL Duration
competition are established:
-
| Motor Class | Length
Minimum (cm) | Length
Maximum (cm) | Circumference
Minimum (mm) | Circumference
Maximum (mm) | Weighting Factor |
