hinged movable surface used for roll control on an
airplane. Found near the tips of the wing.
shape that a wing has when you look at it from the end.
There are many kinds of airfoils, from very simple flat plates,
like our gliders, to graceful teardrop curves to sharp edged
difference between the direction the airplane is pointing
and the direction it is going.
The angle of attack is what flight is all about.
At a large angle of attack, an airplane can fly more slowly.
Too large an angle of attack, and the wings stall, or lose
lift. This can happen no matter which way the plane is
pointing, because it also matters which way the plane is going.
attitude of an airplane is which side up it is. It
consists of three parts: Pitch, Yaw, and Roll.
small wing in front of the large wing on an airplane.
Sometimes called a stabilizer - but here's the secret - in this
case the wing
is really the stabilizer. Canards usually have a movable
part for control, called the elevator. The word "Canard"
comes from the French word for "duck". Perhaps the wing in
the back looks like a long-necked duck in flight.
is the place where something balances. It exists even if
there is no gravity - in fact, its real name is "Center of
Mass", but for practical purposes they are the same thing.
hinged, movable surface used for pitch control on an
airplane. Usually found on the stabilizer at the the tail
of the airplane, but may also be on the canard, or on a flying
wing it may be on the wing itself.
an airplane, the fin is in the back. Sometimes called the
'rudder', the rudder is actually the movable part attached to
angle the fuselage makes to the ground. When the nose is
pointed up, it is said to be pitched up. Not to be
confused with Angle of Attack
angle the wings make to the ground. When the wings are
level, the roll is zero.
hinged, movable surface used for yaw control on an
airplane. Found on the vertical fin.
small wing behind the large wing on an airplane. Wings
don't like to fly on their own and must either be shaped
carefully or be given help. A very simple stabilizer is
the feathers on an arrow.
usually have a movable part for control, called the elevator.
stall occurs when a lifting surface (wing, fin, stabilizer,
canard) has too large an angle of attack. The air can't
follow the shape of the wing anymore, so the lift is
of the airplane's nose left or right.
