Centre of Gravity--The centre of weight.
Cabane--A combination of two pylons, situated over the fuselage,
and from which anti-lift wires are suspended.
Cloche--Literally ``bell.'' Is applied to the bell-shaped construction
which forms the lower part of the pilot's control lever in
a Bleriot monoplane, and to which the control cables are
attached.
Centrifugal Force--Every body which moves in a curved path is
urged outwards from the centre of the curve by a force termed
``centrifugal.''
Control Lever--A lever by means of which the controlling surfaces
are operated. It usually operates the ailerons and elevator. The
``joy-stick".
Cavitation, Propeller--The tendency to produce a cavity in the air.
Distance Piece--A long, thin piece of wood (sometimes tape) passing
through and attached to all the ribs in order to prevent them from
rolling over sideways.
Displacement--Change of position.
Drift (of an aeroplane as distinct from the propeller)--The horizontal
component of the reaction produced by the action of driving
through the air a surface inclined upwards and towards its direction
of motion PLUS the horizontal component of the reaction produced
by the ``detrimental'' surface PLUS resistance due to
``skin-friction.'' Sometimes termed ``head-resistance.''
Drift, Active--Drift produced by the lifting surface.
Drift, Passive--Drift produced by the detrimental surface.
Drift (of a propeller)--Analogous to the drift of an aeroplane.
