A"ër*o*plane` (&?;), n. [Aëro-
+ plane.] A flying machine, or a small plane for
experiments on flying, which floats in the air only when propelled through
it.
A"ër*o*plane` (?), n.
[Aëro- + plane.] (Aëronautics) A
light rigid plane used in aërial navigation to oppose sudden
upward or downward movement in the air, as in gliding machines;
specif., such a plane slightly inclined and driven forward as a
lifting device in some flying machines; hence, a flying machine using
such a device. These machines are called monoplanes, biplanes,
triplanes, or quadruplanes, according to the number of main supporting
planes used in their constraction. Being heavier than air they depend
for their levitation on motion imparted by one or more propellers
actuated by a gasoline engine. They start from the ground by a run on
small wheels or runners, and are guided by a steering apparatus
consisting of horizontal and vertical movable planes. There are many
varieties of form and construction, which in some cases are known by
the names of their inventors.
{ Pas"sive bal*loon" or a"ër*o*plane }.
One unprovided with motive power.
