Streamlining reduces the amount of resistance experienced
by an airfoil.
Streamlining is the shaping of an object, such as an aircraft body or
wing, to reduce the amount of drag or resistance to motion through a stream
of air. A curved shape allows air to flow smoothly around it. A flat shape
fights air flow and causes more drag or resistance. Streamlining reduces
the amount of resistance and increases lift.
To produce less resistance, the front of the object should be well rounded
and the body should gradually curve back from the midsection to a tapered
