- 23.1 Scope
-
Cluster Altitude (CA) is comprised of six events open to single staged model rockets.
- 23.2 Purpose
-
The purpose of this event is to foster the understanding and execution of a fundamental model rocket skill: clustering. The
purpose of the competition is to achieve the highest altitude.
- 23.3 Retained Motors
-
All motor cases are to be retained in the model. Following an official flight, a contestant must present his/her model as
recovered to a contest official for verification of motor casing retention or the flight will be disqualified.
- 23.4 Winner
-
The person achieving the highest altitude is the winner.
- 23.5 Classes
-
The following five classes of Cluster Altitude are established:
-
| Class Name | Weighting Factor |
|---|
| 1/8A x 2 Motor CA | 12 |
| 1/4A x 2 Motor CA | 12 |
| 1/2A x 3 Motor CA | 14 |
| A x 4 Motor CA | 16 |
| B x 5 Motor CA | 18 |
| C x 6 Motor CA | 20 |
- 23.6 Simultaneous Ignition
-
All motors of Cluster Altitude event models shall be ignited on or instantaneously after the model's first motion (i.e.,
"Simultaneous Ignition").
-
Partial cluster ignition shall be deemed a qualified flight unless disqualified for other safety reasons by the RSO. Unignited
motors carried aloft shall be retained within the model.
- 23.7 Partial Ignition
-
Models that do not ignite all motors in flight will be considered official flights. An entry which fails to ignite all of its
motors is considered a qualified flight unless it is unsafe (Rule
11.1), experiences a catastrophic failure (Rule
11.5), or the
track is lost (Rule 14.9).
- 24 Reserved for future events
