Ae

Aeolipile
A round vessel caused to rotate by the force of tangentially escaping steam: an early example of jet propulsion.
Aeolotropy
Aeolotropy is the antithesis of isotropy.
Aeon
In astronomical terms, 1,000 million years.
Aeration
Preparation of a saturated solution of air gases by either spraying the solution in air or by bubbling air through it.
Aeration Tank
A chamber used to inject air into water.
Aerial
Another name for an antenna.
Aerial Acid
An old name for carbon dioxide.
Aero Metal
A metal used in casting made from aluminium, zinc and copper.
Aerobatics
Voluntary manoeuvres, initiated by a pilot, other than those for conventional flight.
Aerobe
An organism that uses oxygen as the terminal electron acceptor in respiration.
Aerobic
Requiring or occurring in the presence of oxygen.
Aerobiology
The study of the distribution of living organisms freely suspended in the atmosphere.
Aerodontalgia
A toothache brought on by a change in ambient pressure.
Aerodrome
Alternative name for Airfield.
Aerodynamic Diameter
The diameter of a sphere with unit density that has aerodynamic behavior identical to that of the particle in question.
Aerodynamic Drag
Resistance of a vehicle body to motion through the air. A smooth surface has less drag than a rough one.
Aerodynamic Force
The force exerted by a moving gaseous fluid upon a body completely immersed in it.
Aerodynamic Heating
The heating of a body produced by passage of air or other gases over the body.
Aerodynamic Noise
Sound generated by turbulent flow is just as if the field were generated by a distribution of quadrupole sources.
Aerodynamic Trail
A condensation trail formed by adiabatic cooling to saturation of air passing over the surfaces of high-speed aircraft.
Aerodynamic Vehicle
A device, such as an airplane, glider, etc., capable of flight only within a sensible atmosphere and relying on aerodynamic forces to maintain flight.

Aeroelasticity
Any phenomenon which includes the mutual interaction between aerodynamic loads and structural deformation.
Aeroemphysema
A swelling condition caused by the formation of gas in the tissues of the body
Aerofoil
An aerofoil is shaped so that air flows faster over the top than under the bottom. There is, therefore, a greater pressure below the aerofoil than above it. This difference in pressure produces the lift.
Aerolite
A stony meteorite, composed primarily of silicates.
Aerolithology
The science of aerolites - stony meteorites.
Aerology
The study of atmospheric conditions away from ground level.
Aerometer
An instrument for determining the weight, density and other properties of air or other gases.
Aerometry
The science of measuring the air, including the doctrine of its pressure, elasticity, rarefaction, and condensation.
Aeronautics
The term "aeronautics" originated in France, and was derived from the Greek words for "air" and "to sail".
Aeronomy
The study of the upper regions of the atmosphere where ionization, dissociation, and chemical reactions take place.
Aero-Otitis Media
An inflammatory reaction of the middle ear resulting from a difference in pressure between the gas in the middle ear and the surrounding atmosphere.
Aeropause
A region of indeterminate limits in the upper atmosphere, considered as a boundary or transition region between the denser portion of the atmosphere and space.
Aerosol
A colloid in which solid particles or liquid droplets are suspended in a gas.
Aerostat
Denotes a lighter than air craft.
Aerothermodynamic
A branch of thermodynamics relating to the heating effects associated with the dynamics of a gas.
Aerothermodynamic Border
An altitude at about 100 miles, above which the atmosphere is so rarefied that the skin of an object moving through it at high speeds generates no significant heat.
Aerothermoelasticity
The study of the response of elastic structures to the combined effect of aerodynamic heating and loading.
Aether
An invisible medium that was thought to suffuse all space.
