The Airfoil Surface Area Calculator is a useful tool for engineers, aviation enthusiasts, and students to determine the surface area of an airfoil. By using the chord and span dimensions, this calculator provides a straightforward way to calculate the total surface area, which is essential for aerodynamic analysis and design.
Formula
The formula to calculate the surface area of an airfoil is:
A = c × s
Where:
- A is the surface area in square meters.
- c is the chord length in meters.
- s is the span length in meters.
How to Use
- Input the chord length (c) in meters.
- Enter the span length (s) in meters.
- Click the "Calculate" button.
- The calculator will display the surface area (A) in square meters.
Example
If an airfoil has a chord length of 2 meters and a span length of 10 meters, the calculated surface area will be:
A = 2 × 10 = 20 square meters
FAQs
- What is the chord length?
The chord length is the distance from the leading edge to the trailing edge of the airfoil. - What is the span length?
The span length is the distance between the tips of the airfoil. - Why is surface area important in aerodynamics?
Surface area impacts lift, drag, and overall aerodynamic performance of an airfoil. - Can this calculator be used for non-standard airfoils?
