Difference between Aerofoil and Airfoil

AEROFOIL vs AIRFOIL: NOUN

A wing of an aircraft.
A structure shaped to produce lift when moving in air.
A plane or arched surface for sustaining bodies by its movement through the air; a spread wing, as of a bird.
A device that provides reactive force when in motion relative to the surrounding air; can lift or control a plane in flight

A wing of an aircraft.
A structure shaped to produce lift when moving in air.
A surface such as the wing of an airplane designed to provide reactive force when in motion relative to the surrounding air.
A part or surface, such as a wing, propeller blade, or rudder, that interacts with a flow of air to provide stability, rotation, lift, or thrust.
A device that provides reactive force when in motion relative to the surrounding air; can lift or control a plane in flight

You will see that the new fan has nice straight blades and in picture 1. you can see the aerofoil shape I mentioned before.
As soon as the aerofoil was brought into wind it would race up the wire from bottom to top.

For aerofoil surfaces the measurement should be taken in the direction of the gas flow.
The theoretical inviscid flow condition is such that no force on the aerofoil exists at all.
Perhaps the Whirlwind needed a more aggressive aerofoil given less horses under the bonnet?
High lift is obtained by double aerofoil elements mainly used in aeroplane wing design.
