Airfoil Surface Area Calculator















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

  1. Input the chord length (c) in meters.
  2. Enter the span length (s) in meters.
  3. Click the "Calculate" button.
  4. 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

  1. What is the chord length?
    The chord length is the distance from the leading edge to the trailing edge of the airfoil.
  2. What is the span length?
    The span length is the distance between the tips of the airfoil.
  3. Why is surface area important in aerodynamics?
    Surface area impacts lift, drag, and overall aerodynamic performance of an airfoil.
  4. Can this calculator be used for non-standard airfoils?
    Yes, as long as the chord and span are accurately measured.
  5. What units does this calculator use?
    The calculator uses meters for both chord and span, and the result is in square meters.
  6. Can I input dimensions in feet?
