det farlig å drive med modellraketter?
Det er ikke farlig å drive med modellraketter
om man er fornuftig, og følger visse sikkerhetsprosedyrer.
Den amerikanse organisasjonen NAR (National Association of Rocketry)
har utarbeidet følgende retningslinjer for sikkerhet. Følger
man dem og samtidig sper på med litt sunn fornuft burde
det ligge vel til rette for en trygg men spennende hobby.
NARs Model Rocket Safety Code
I will use only lightweight, non-metal parts for the nose,
body, and fins of my rocket.
I will use only certified, commercially-made model rocket
motors, and will not tamper with these motors or use them
for any purposes except those recommended by the manufacturer.
- Ignition System.
I will launch my rockets with an electrical launch system
and electrical motor igniters. My launch system will have
a safety interlock in series with the launch switch, and will
use a launch switch that returns to the "off" position when
If my rocket does not launch when I press the button of my
electrical launch system, I will remove the launcher's safety
interlock or disconnect its battery, and will wait 60 seconds
after the last launch attempt before allowing anyone to approach
- Launch Safety.
I will use a countdown before launch, and will ensure that
everyone is paying attention and is a safe distance of at
least 15 feet away when I launch rockets with D motors or
smaller, and 30 feet when I launch larger rockets. If I am
uncertain about the safety or stability of an untested rocket,
I will check the stability before flight and will fly it only
after warning spectators and clearing them away to a safe
I will launch my rocket from a launch rod, tower, or rail
that is pointed to within 30 degrees of the vertical to ensure
that the rocket flies nearly straight up, and I will use a
blast deflector to prevent the motor's exhaust from hitting
the ground. To prevent accidental eye injury, I will place
launchers so that the end of the launch rod is above eye level
or will cap the end of the rod when it is not in use.
My model rocket will not weigh more than 1,500 grams (53 ounces)
at liftoff and will not contain more than 125 grams (4.4 ounces)
of propellant or 320 N-sec (71.9 pound-seconds) of total impulse.
If my model rocket weighs more than one pound (453 grams)
at liftoff or has more than four ounces (113 grams) of propellant,
I will check and comply with Federal Aviation Administration
regulations before flying.
- Flight Safety.
I will not launch my rocket at targets, into clouds, or near
airplanes, and will not put any flammable or explosive payload
in my rocket.
- Launch Site.
I will launch my rocket outdoors, in an open area at least
as large as shown in the accompanying
table, and in safe weather conditions with wind speeds
no greater than 20 miles per hour. I will ensure that there
is no dry grass close to the launch pad, and that the launch
site does not present risk of grass fires.
- Recovery System.
I will use a recovery system such as a streamer or parachute
in my rocket so that it returns safely and undamaged and can
be flown again, and I will use only flame-resistant or fireproof
recovery system wadding in my rocket.
- Recovery Safety.
I will not attempt to recover my rocket from power lines,
tall trees, or other dangerous places.
