Static Pressure : Pressure which exertx a force on all bodies, acts equally in all directions.
Dynamic Pressure : The pressure on the surface of the body which causes the moving air to stop
Streamline : a path traced out by a single particle of airflow such that this particle does not cross the path of any other
Stagnation : At the leading edge of the wing, the air is brought completely rest.
Airspeed : the principle of the stagnation point is used in the measurement of airspeed
Equivalent Air Speed : The airspeed indicator reading when corrected for compressibility at all speed
Indicator Air Speed : The Dynamic Pressure of air against a vehicle
True Air Speed: The equivalent airspeed corrected for density
Mach number : The ratio of TAS to the local speed of sound(LSS)
Mean Chamber Line : a line which joins the leading edge to the trailing edge .
Angle of attack: angle between the chord line of the wing and the direction of the relative airflow
Wash out : Decrease in wing angle of incidence from root to tip,
Wash in : An increase in angle of incidence from root to tip
Mean Chord : wing area divided by span
Taper Ratio : ratio of the root chord to tip chord
Aspect Ratio : The Ratio of the wing span to the mean chord, or alternatively span to wing area
Sweep Angle : The angle between the lateral axis and the Y. chord line.
Dihedral : The upward inclination of wing to the plane through the lateral axis
Anhedral : The downward inclination of wing to the plane through the lateral axis
