●● Planform
Answer: the shape of the wing viewed from above


●● Chord Line
Answer: An imaginary straight line from the leading edge to the trailing
edge of an airfoil.


●● Leading Edge
Answer: The part of the airfoil that meets the airflow first.


●● Trailing Edge
Answer: The last point on an airfoil that interacts with the airflow
around the wing.


●● Mean Camber Line
Answer: An imaginary line between the leading and trailing edges and
halfway between the airfoil's upper (curved) and lower (flat) surfaces

, ●● Maximum Camber
Answer: the maximum distance of the mean camber line from the chord
line


●● Symmetrical Airfoil
Answer: An airfoil having the same shape on the top and bottom.


●● Cambered Airfoil
Answer: an airfoil that has a curved upper surface and a flat lower
surface


●● Adverse Pressure Gradient
Answer: A pressure gradient of increasing static pressure in the direction
of airflow.
