moveable part of the wings on an airplane that control
pitching and banking movements.
shape of a wing, propeller blade, vertical and horizontal
fins, etc., whose shape and orientation controls stability,
direction, lift, thrust or propulsion.
downward inclination of an aircraft wing from true horizontal.
Most airplanes have "dihedral".
Ratio - The
ratio of the wing chord to the wing span.
of gravity - The point at which an item balances.
upward inclination of an aircraft wing from true horizontal.
Dihedral is designed into an airplane's wings to give
it more stability.
moveable part of the wing that is dropped into the airstream
to increase lift and/or drag.
Edge - The
very front, running along the length of the wing, of
the airplane's wing.
Coefficient - The
measure of lift efficiency for an airfoil. This is usually
determined by wind tunnel testing.
Arm - The distance from a point of torque or
- The first of it's kind that is built. In
our case, it would be the first airplane built from
ribs are placed along the wing's axis and determine
the airfoil of the wing. They also transfer the airplane's
load to the wing spar.
innermost edge of the wing parallel with the fuselage.
Speed - The
speed at which an aircraft will stall or stop flying
in the landing congifuration.
furthest edge of a wing parallel with the fuselage.
Edge - The
rearmost edge of a wing, running along the length of
the wing, in front of the any flaps or ailerons.
top of the fuselage behind the cockpit area of the airplane.
The turtledeck does not normally carry any flight loads
of the airplane and is mainly meant to steamline the
Coefficients - The
size of the vertical and horizontal tails in correlation
to the wing. These coefficients determine the amount
of control and stability the airplane will have.
called "Wing Twist". The term applied to the
trailing edge of a wingtip being twisted up more than
the shape of the wing at the root. This allows the airplane's
wing to stall at the root and the tips to remain in
the flying condition as the airplane nears stall speed.
Chord - The
dimension of the wing from the leading edge to the trailing
Loading - The
ratio of weight of the aircraft to the area of the wing.
Planform - The
shape of the wings on an aircraft as viewed from directly
above or below the aircraft.
Spar - A rigid or semi-rigid structure that
runs through the wing of an aircraft and carries the
loads of the airplane.
Twist - See
