Wing area is the total surface area of an aircraft’s wings that is exposed to the oncoming air during flight. It is a critical parameter in determining the aerodynamic characteristics and performance of an aircraft. Wing area is typically measured in square units, such as square feet or square meters, and it plays a key role in the generation of lift, the production of drag, and the overall maneuverability of the aircraft. The formula to calculate Wing area as follows:
Where:
- S is the wing area in m2.
- Qw is the Wing dynamic pressure in Pa.
- Cn is the Yawing moment coefficient.
- lv is the Vertical tail moment arm in m.
- Sv is the Vertical tail area in m2.
- Cv is the Vertical tail Lift curve slope in 1/rad.
- β is the Sideslip angle in radian.
- σ is the Sidewash angle in radian.
- Qv is the Tail Dynamic pressure in Pa.
- b is the wingspan in m.
