- 21.1 Scope
- Super-Roc Altitude Competition comprises nine 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 altitude possible with the longest rocket possible without impairing the
structural integrity of the rocket.
-
- 21.2 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.
-
- 21.3 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. The recovery system shall be enclosed totally within the model
until ejection.
-
- 21.4 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.
-
- 21.5 Scoring
- Super-Roc Altitude Competition shall be scored as follows: the length in centimeters of the model, as
measured from the tip of the nose cone to the aftmost end of the motor nozzle, up to the maximum length
for that category, shall be awarded as static points. No additional points are awarded for any length
beyond the maximum. The altitude of the model in meters, as tracked and reduced, shall be awarded as
flight points. The static points and flight points thus obtained shall be multiplied to determine the score.
The contestant achieving the highest score shall be declared the winner.
-
- 21.6 Classes
- This competition is divided into classes based on the permissible total impulse of the motor(s). The
following classes of Super-Roc Altitude competition are established:
-
-
| Motor Class | Minimum Length
(centimeters) | Maximum Length
(centimeters) | Weighting Factor |
| 1/8A | 12.5 | 25 | 13 |
| 1/4A | 25 | 50 | 14 |
| 1/2A | 50 | 100 | 14 |
| A | 75 | 150 | 14 |
| B | 100 | 200 | 15 |
| C | 125 | 250 | 16 |
| D | 150 | 300 | 17 |
| E | 175 | 350 | 18 |
| F | 200 | 400 | 19 |
| G | 225 | 450 | 20
