Great guidance for the safe enjoyment of model
rockets. We strongly suggest you read and heed.
1. Materials. My model rocket will be made of lightweight materials, such as paper,
wood, rubber, and plastic suitable for the power used and the performance of my model
rocket. I will not use any metal for the nose cone, body, or fins of a model rocket.
2.
Motors / Engines I will use only commercial made NAR certified model rocket engines in the
manner recommended by the manufacturer. I will not alter the model rocket engine, its
parts, or its ingredients.
3. Recovery. I will always use a recovery system in my model rocket that will return it
safely to the ground so it may be flown again. I will use only flame resistant recovery
wadding if required.
4. Weight and Power Limits. My model rocket will weigh no more that 1,500 grams (53 oz)
at lift-off, and its rocket engines will produce no more than 320 Newton-seconds (4.45
Newtons equals 1.0 pound) of total impulse. My model rocket will weight no more than the
engine manufacturer's recommended maximum lift-off weight for the engine used, or I will
use an engine recommended by the manufacture for my model rocket.
5. Stability. I will check the stability of my model rocket before its first flight,
except when launching a model rocket of already proven stability.
6. Payloads. Except for insects, my model rocket will never carry live animals or a
payload that's intended to be flammable, explosive, or harmful.
7. Launch site. I will launch my model rocket outdoors in a cleared area, free of tall
trees, power lines, buildings, and dry brush and grass. My launch site will be at least as
large as that recommend in the following table: |
Installed
Total impulse
(Newton-seconds) |
Equivalent
Engine Type |
Minimum
Site Dimension
Feet / Meters |
|
0.00 - 1.25 |

10.01 - 20.00 |
D |
500 / 150 |
|
20.01 - 40.00 |
E |

8. Launcher. I will launch my model rocket from a stable launching device that
provides rigid guidance until the model rocket has reached a speed adequate to ensure a
safe flight. To prevent accidental eye injury, I will always place the launcher so that
the end of the rod is above eye level or I will cap the end of the launch rod when
approaching it. I will cap or disassemble my launch rod when not in use and I will never
store it in an upright position. My launcher will have a jet deflector device to prevent
the engine exhaust from hitting the ground directly. I will always clear the area around
my launch device of brown grass, dry weeds and other east-to-burn materials.
9. Ignition
System. The system I use to launch my model rocket will be remote controlled and
electronically operated. It will contain a launching switch that will return to
"off" when released. The system will contain a removable safety interlock in
series with the launch switch. All persons will remain at least 15 feet (5 meters) from
the model rocket when I am igniting model rocket engines totaling 30 Newton-seconds or
less of total impulse and at least 30 feet (8 meters) from the model rocket when I am
igniting model rocket engines totaling more than 30 Newton seconds of total impels. I will
use only electrical Igniters recommended by the engine manufacturer that will ignite model
rocket engines within one second of actuation of the launching switch.
10. Launch Safety. I will ensure that people in the launch area are aware of the
pending model rocket launch and can see the model rocket's liftoff before I begin my
audible five second countdown. I will not launch a model rocket using it as a weapon. If
my model rocket suffers a misfire, I will not allow anyone to approach it or the launcher
until I have made certain that the safety interlock has been removed or that the battery
has been disconnected from the ignition system. I will wait one minute after a misfire
before allowing anyone to approach the launcher.
11. Flying conditions. I will launch my model rocket only when the wind is less than 20
miles (30 kilometers) an hour. I will not launch my model rocket so it flies into clouds,
near aircraft in flight, or in a manner that is hazardous to people or property.
12. Pre-Launch Test. When conducting research activities with unproved model rocket
designs or methods, I will, when possible, determine the reliability of my model rocket by
pre launch tests. I will conduct the launching of an unproved design in complete isolation
from persons not participating in the actual launching.
13. Launch Angle. My launch device will be pointed within 30 degrees of vertical. I
will never use model rocket engines to propel any device horizontally.
14. Recovery Hazards. If a model rocket becomes entangled in a power line or other
dangerous place, I will not attempt to retrieve it. |
