A model rocket is a miniature rocket patterned after military or space rockets.
Model rockets usually eight less than 4.5 kilograms. Many of them measure
between 20 and 61 centimeters long. Model rockets can elevate as high as 480
kilometers an hour.(Rocket,Model World Book Encyclopedia 1992)
Rocketry is dated back to 1048 AD were the Chinese knew them as “Fire
Arrows.” Rockets first came to the new world during the war of 1812. Rockets are

There are seven basic parts to a model rocket. The body tube is the part
which all other parts are attached to. The launch lug is a narrow paper or plastic

rocket vertical. The next part is the fins. The fins help the rocket travel straight
during flight. The engine holder is a ring cemented inside the bottom of the body
tube. The rockets engine fits in the holder. The engine of most rockets consists of
a thick cardboard tube that contains the solid fuel. The nose cone forms the top

engine ignition system. A typical launch pad is made up of a three-legged base
and a deflector. The ignition system includes the launch controller pad and a
battery.(Rocket,Model World Book Encyclopedia 1992)

rockets. Aerodynamics is a branch of fluid mechanics that deals with motion of air
