Vocabulary : Aerophone to Aerostat
Aerophone : A form of combined speaking and ear trumpet. ;; An instrument, proposed by Edison, for greatly intensifying speech. It consists of a phonograph diaphragm so arranged that its action opens and closes valves, producing synchronous air blasts sufficient to operate a larger diaphragm with greater amplitude of vibration.Aerophyte : A plant growing entirely in the air, and receiving its nourishment from it; an air plant or epiphyte.
aeroplane : A flying machine, or a small plane for experiments on flying, which floats in the air only when propelled through it. ;; A light rigid plane used in aerial 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. ;; One unprovided with motive power.
Aeroplanist : One who flies in an aeroplane.
