aero-, aer-, aeri-

(Greek: air, mist, wind)


The wings and bodies of airplanes have an aerodynamic shape.

aerodynamic drag
The opposing force encountered by a body moving relative to a fluid; for example, an aircraft in flight displacing the air in its path.

The two primary forces in aerodynamics are lift and drag.




Any aircraft that is heavier than air and derives its lift chiefly from aerodynamic forces.
aeroelastic, aeroelasticity
1. Pertaining to, or resulting from aerodynamic forces; such as, tests to determine the aeroelastic stress on a building.
2. Deformable by aerodynamic forces; such as, distortion (as from bending) in a structure (as an airplane wing or a building) caused by aerodynamic forces.
Nitrogen bubbles formed in the blood or tissues during decompression sickness; also known as decompression sickness.
Pulmonary emphysema and edema with collection of nitrogen bubbles in the tissues of the lung; due to excessively rapid atmospheric decompression.
aerogastria (s) (noun), aerogastrias (pl)
1. The presence of gas in the stomach; stomach bubbles: Also known as "blocked aerogastria which is caused when the lower esophagu, the canal that connects the throat to the stomach, prevents belching.
2. Distention of the stomach with gas.
2. A highly porous solid formed by replacement of liquid in a gel with a gas so that there is little shrinkage.
3. A gel formed by the dispersion of air in a solidified matrix; a solid foam, as Styrofoam.
4. A porous solid formed by replacing the liquid of a gel with a gas; such as, rigid plastic foam.
A gas-forming microorganism.
Production of gas, as with microorganisms.
aerogenic, aerogenous
Producing gas; said of bacteria that liberate free gaseous products.
