- 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.
- Motors. I will use only commercially-made,
NAR-certified model rocket motors in the manner
recommended by the manufacturer. I will not alter the
model rocket motor, its parts, or its ingredients in any
way.
- 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 wadding is required by the design of
my model rocket.
- Weight and Power Limits. My model rocket will
weigh no more than 1,500 grams (53 ounces) at lift-off
and its rocket motors will produce no more than 320
Newton-seconds (71.9 pound-seconds) of total impulse. My
model rocket will weigh no more than the motor
manufacturerÕs recommended maximum lift-off weight for
the motors used, or I will use motors recommended by the
manufacturer for my model rocket.
- Stability. I will check the stability of my model
rocket before its first flight, except when launching a
model rocket of already proven stability.
- Payloads. My model rocket will never carry live
animals (except insects) or a payload that is intended to
be flammable, explosive, or harmful.
- 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 area
will be at least as large as that recommended in the
accompanying table.
- Launcher. I will launch my model rocket from a
stable launch device that provides rigid guidance until
the model rocket has reached a speed adequate to ensure a
safe flight path. To prevent accidental eye injury, I
will always place the launcher so the end of the rod is
above eye level or I will cap the end of the 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 motor exhaust from hitting the ground
directly. I will always clear the area around my launch
device of brown grass, dry weeds, or other easy-to-burn
materials.
- Ignition System. The system I use to launch my
model rocket will be remotely controlled and electrically
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
from the model rocket when I am igniting model rocket
motors totalling 30 Newton-seconds or less of total
impulse and at least 20 feet from the model rocket when I
am igniting model rocket motors totalling more than 30
Newton-seconds of total impulse. I will use only
electrical igniters recommended by the motor manufacturer
that will ignite model rocket motors within one second of
actuation of the launching switch.
- 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 lift-off before I begin my
audible five-second countdown. I will not launch my model
rocket so its flight path will carry it against a target.
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.
- Flying Conditions. I will launch my model rocket
only when the wind is less than 20 miles per 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.
- Pre-Launch Test. When conducting research
activities with unproven 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 unproven design in complete isolation
from persons not participating in the actual launching.
- Launch Angle. My launch device will be pointed
within 30 degrees of vertical. I will never use model
rocket motors to propel any device horizontally.
- Recovery Hazards. If a model rocket becomes
entangled in a power line or other dangerous place, I
will not attempt to retrieve it.
