Airfoil Aspect Ratio Formula
The following formula is used to calculate the aspect ratio of an airfoil.
AR = \frac{b^2}{A}Variables:
- AR is the aspect ratio
- b is the wingspan
- A is the wing area
To calculate the aspect ratio, square the wingspan and divide it by the wing area.
What is an Airfoil Aspect Ratio?
The aspect ratio of an airfoil is a measure of how long and slender the wing is. It is defined as the ratio of the wingspan to the average chord (the width of the wing). A higher aspect ratio indicates a longer, narrower wing, which is typically more efficient for producing lift and reducing drag. Conversely, a lower aspect ratio indicates a shorter, wider wing, which can provide better maneuverability and structural strength. The aspect ratio is an important parameter in the design and performance of aircraft and other aerodynamic structures.
How to Calculate Airfoil Aspect Ratio?
The following steps outline how to calculate the Airfoil Aspect Ratio.
- First, determine the wingspan (b).
- Next, determine the wing area (A).
- Next, calculate the aspect ratio using the formula AR = b² / A.
- Finally, calculate the Airfoil Aspect Ratio.
- After inserting the values and calculating the result, check your answer with the calculator above.
