Dragslows
the forward movement of an aircraft.
Liftis
produced by air flowing over the wings.
Gravity is the force that pulls an aircraft down.

Educational Wind Tunnel
Science Club- Class 6The Basic Principles of Flight
A wind tunnel is used by scientists to
test model airplanes which have the same shape as actual airplanes. Using
the wind tunnel gives the scientists information about how a certain plane
would respond in flight.
The educational wind tunnel allows
students to explore the basic principles of flight using model airplanes
made from balsa wood.
Jetfire Glider
Skyray Radio Controlled Rudder
and Elevator
The
Jetfire glider is restrained by a line to move only in the vertical
direction. The concept of lift can be demonstrated by adding weight to the
glider in the form of washers. The Jetfire glider can lift4 washers.
The
Skyray is one of the most popular balsa wood model airplane of all time.
This particular airplane has had its wings remove and is outfitted with a
radio controlled rudder and elevator. It is mounted on a two axis base which
allows it to pitch and yaw when in the wind tunnel. Students can observe
firsthand the use of control surfaces to effect the airplanes flight.
