Airfoil Aspect Ratio Calculator - Calculator Wow (2024)

The Airfoil Aspect Ratio Calculator is an essential tool for aircraft designers and aerodynamics enthusiasts. The aspect ratio of an airfoil plays a crucial role in determining its aerodynamic efficiency and performance. By calculating the aspect ratio, you can assess the potential lift and drag characteristics of the wing, which is vital for designing efficient and high-performance aircraft. This calculator simplifies the process of determining the aspect ratio based on wingspan and wing area.

Formula

The formula for calculating the airfoil aspect ratio is:

AR = (b²) / A

Where:

• AR is the airfoil aspect ratio.
• b is the wingspan in meters.
• A is the wing area in square meters.

This formula provides a measure of the efficiency of a wing, with higher aspect ratios generally indicating better aerodynamic performance.

How to Use

1. Enter Wingspan: Input the wingspan of the airfoil in meters.
2. Enter Wing Area: Input the wing area in square meters.
3. Click Calculate: Press the “Calculate” button to compute the aspect ratio.
4. View the Result: The calculated aspect ratio will be displayed.

Example

Consider an airfoil with a wingspan of 10 meters and a wing area of 50 square meters. To find the aspect ratio:

1. Enter 10 for the wingspan.
2. Enter 50 for the wing area.
3. Click “Calculate.”
4. The result will be (10 * 10) / 50 = 2.00, indicating an aspect ratio of 2.00.
