Model rocketry is a safe educational activity
that teaches students about aerodynamics and physics in a real world hands on
activity. It also is a great way for students to use their own hands to
create the model rocket and then experience of a successful flight and recovery.
The parts of a model rocket
include a nose cone, body tube, fins, engine mount, launch lug & recovery system such as a
parachute or streamer.
A model rocket motor is inserted and when ignited, creates
thrust that propels the rocket forward. A small charge in the forward end of the
model rocket motor pushes the nose cone & recovery system out of the front of
the rocket at the top of it's flight to bring the model rocket gently back down
to earth.
The fins of a model rocket creates a guiding force by moving the center of
drag (center of pressure) behind the center of the the weight (center of
gravity) of the rocket. When the center of pressure is behind the center of
gravity on the model rocket, the model rocket will point straight into the
direction it is being pushed by the model rocket motor.
A model rocket is guided to a straight flight by a launch rod mounted to a
launch pad. The model rocket is slid onto a launch rod & then electrically
ignited from a safe distance
