More About Rocket Motors
How rocket motor classification works
Model rocket motors are classified by letters (A to O) and numbers. The letter indicates the total impulse range, and the number represents the average thrust in newtons. For example, a C6-3 motor has a total impulse range of 5.01 to 10 N·s, produces 6 N of average thrust, and has a delay of 3 seconds before firing the ejection charge.
Motor sizes and power levels
- Low Power Motors (A to E): Suitable for beginners and small rockets.
- Mid Power Motors (F to G): Require some experience and can lift larger rockets.
- High Power Motors (H and above): Used for larger, more advanced rockets and
require certification.
Motor Codes
- A motor code like C6-3 breaks down as follows:
- C: Total impulse range.
- 6: Average thrust in newtons.
- 3: Delay in seconds before the ejection charge.
Storage and handling
- Store motors in a cool, dry place away from heat sources and direct sunlight.
- Handle motors with care, avoiding rough handling or dropping.
Safety and certification
- High power motors (H and above) require certification from organizations like the
National Association of Rocketry (NAR) or Tripoli Rocketry Association (TRA). - Always use safety glasses and follow launch safety guidelines.
