Wing Aspect Ratio (AR) is a fundamental parameter in aircraft design that describes the ratio of a wing’s wingspan to its mean chord (average width). It is an important factor in determining an aircraft’s aerodynamic performance, particularly its lift and induced drag characteristics.
Formula: The formula for calculating Wing Aspect Ratio (AR) is straightforward:
- AR is the Wing Aspect Ratio (dimensionless).
- Wingspan is the total length of the wing from tip to tip (in meters or feet).
- Mean Chord is the average width of the wing from the leading edge to the trailing edge (in meters or feet).
