- Aeration
-
- Act of combining substance with air
- A foaming of a liquid because air has been introduced into the fluid.
- When it occurs in certain liquids, it decreases the efficiency of the liquid.
- Aeration test burner
- (ATB) A burner for measuring the features of the combustion of commercial gases
- Aerial
- British term for Antenna.

- Aerial bunched conductors
- (ABC) Method of power transmission where the three conductors are twisted into a
thicker insulated cable.
- More expensive but better at surviving blizzard conditions than normal separate conductors.
- Aerobar
-
An extension to bicycle handlebars which project forward to give the rider an alternate riding position and a lower, more aerodynamic position.
Aerobar
- His elbows rest in the pads while he grabs the upright ends of the bars.
- Aerobars were popularized by triathletes and Greg LeMond.
- Aerobars
- Sometimes referred to as Tri bars.
- Aerobars popularized by triathletes and Greg LeMond, are attached to handlebars in order to provide a rider with a lower, more aerodynamic position.
- Aerobic sealer
- A substance, such as room temperature vulcanizing
(RTV), a common silicone
rubber sealing compound) that requires the presence of oxygen to hold parts
together.

- Aerodynamic balance
- A balance, usually but not necessarily in a wind tunnel, designed for measuring aerodynamic forces or moments.
- Aerodynamic center
- The point about which the pitching moment coefficient is constant for a range of airfoil incidence.
- Aerodynamic drag
- The Resistance of the air to forward movement,
sometimes called Air resistance.
- This is a factor of
- the shape of the vehicle (drag coefficient and frontal area)
- the objects which stick out (i.e., mirrors, mufflers, bumpers)
- the amount of turbulence at the rear of the vehicle
- the nature of the vehicle's skin surface
- the amount of air going through the vehicle for cooling and ventilation.
- The faster you go, the greater the air friction (air friction = velocity x velocity).
- The faster you go, the greater the amount of power needed to overcome this drag (power = velocity x velocity x velocity).
- This is a factor of
- Aerodynamic heating
- The heating of a vehicle passing through the atmosphere, caused by friction and compression of air (or other gas).
- Aerodynamics
- The study of the flow of air as it passes over and around a moving object as well
as the forces which the air makes on the object.
- An airplane, for instance, needs positive lift to get it airborne and negative lift to help it land.
- Thus the shape of a land vehicle (car, bicycle, etc.) either promotes positive or negative lift.
- Race cars may use spoilers and wings (Air foils) to control lift.
- In vehicle design, the airflow is monitored in a wind tunnel.
- As well, aerodynamics also studies the most efficient shapes for increased speed and fuel economy.
- Aerodynamic stance
- In order to create less Drag, the vehicle is lowered
closer to the ground.
- This improves the flow of air over the vehicle.
- A better aerodynamic stance helps the vehicle to go faster when it is going in a straight line as well as give better Fuel economy.
- Also, when a vehicle sits lower to the ground, it has a low center of gravity which makes it more stable when going through turns and enables the driver to maintain a higher speed.
- Aerofoil
- British spelling for airfoil a body or body panel shaped like a wing so as to
produce an aerodynamic reaction (lift) normal to its direction of motion, for a
small resistance (drag), in that plane; e.g., a wing, plane, aileron, tailplane,
rudder, or elevator.

- One of a pair of road bike brake levers employing hidden cables that travel out the back of the level body and under the handlebar tape.
- Aero system
- A roof rack designed for cars without external rain gutters. The rack is held on by clips that extend down into the door.
- AEV
- Acronym for Automatic expansion valve.
