Aspect Ratio (AR) vs Wingspan (b)
Wing Aspect Ratio
Aspect ratio (AR) measures how slender a wing is. It is defined as the square of the wingspan divided by the wing planform area, or equivalently, the wingspan divided by the mean chord.
Formula
AR = b² / S
High aspect ratio wings (like gliders, AR > 15) have low induced drag and are efficient for slow, soaring flight. Low aspect ratio wings (like fighters, AR < 5) are better for high-speed maneuverability and structural strength.
Example Calculation
A transport aircraft with a 35 m wingspan and 120 m² wing area.
- 01AR = 35² / 120 = 1225 / 120
- 02AR = 10.208
- 03Mean chord = 120 / 35 = 3.429 m
