A round vessel caused to rotate by the force of tangentially escaping steam: an early example of jet propulsion.
Aeolotropy is the antithesis of isotropy.
In astronomical terms, 1,000 million years.
Aerated Conrete
Concrete formed using gas-forming admixtures such as powdered zinc or aluminum combined with calcium hydroxide or hydrogen peroxide that form hydrogen or oxygen bubbles in the cement mix.
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.
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.
The study of the interaction of projectiles or high speed vehicles with the atmosphere.
Voluntary manoeuvres, initiated by a pilot, other than those for conventional flight.
An organism that uses oxygen as the terminal electron acceptor in respiration.
Requiring or occurring in the presence of oxygen.
The study of the distribution of living organisms freely suspended in the atmosphere.
A toothache brought on by a change in ambient pressure.
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.

Any phenomenon which includes the mutual interaction between aerodynamic loads and structural deformation.
A swelling condition caused by the formation of gas in the tissues of the body
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.
A stony meteorite, composed primarily of silicates.
The science of aerolites - stony meteorites.
The study of atmospheric conditions away from ground level.
An instrument for determining the weight, density and other properties of air or other gases.
The science of measuring the air, including the doctrine of its pressure, elasticity, rarefaction, and condensation.
The term "aeronautics" originated in France, and was derived from the Greek words for "air" and "to sail".
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.
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.
A colloid in which solid particles or liquid droplets are suspended in a gas.

Denotes a lighter than air craft.
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.
The study of the response of elastic structures to the combined effect of aerodynamic heating and loading.
An invisible medium that was thought to suffuse all space.
