THE AEROPLANE SHED.--This should be kept as clean and
orderly as possible. A clean, smart shed produces briskness,
energy, and pride of work. A dirty, disorderly shed nearly
always produces slackness and poor quality of work, lost
tools and mislaid material.
GLOSSARY
Aeronautics--The science of aerial navigation.
Aerofoil--A rigid structure, of large superficial area relative to its
thickness, designed to obtain, when driven through the air at an
angle inclined to the direction of motion, a reaction from the air
approximately at right angles to its surface. Always cambered
when intended to secure a reaction in one direction only. As the
term ``aerofoil'' is hardly ever used in practical aeronautics,
I have, throughout this book, used the term SURFACE, which,
while academically incorrect, since it does not indicate thickness,
is a term usually used to describe the cambered lifting surfaces,
i.e., the ``planes'' or ``wings,'' and the stabilizers and the
controlling aerofoils.
Aerodrome--The name usually applied to a ground used for the
practice of aviation. It really means ``flying machine,'' but is
never used in that sense nowadays.
Aeroplane--A power-driven aerofoil with stabilizing and controlling
surfaces.
Acceleration--The rate of change of velocity.
Angle of Incidence--The angle at which the ``neutral lift line'' of
a surface attacks the air.
Angle of Incidence, Rigger's--The angle the chord of a surface makes
with a line parallel to the axis of the propeller.
