Digitize Airfoil Shapes with Ice Accretion for Aerodynamics and Simulation

Digitizing Iced Airfoils with Airfoil Digitizer ❄️✈️

Accurately modeling the effects of ice accretion on airfoils is essential for understanding performance degradation in real-world flight conditions. At Hanley Innovations, we make this possible with Airfoil Digitizer — a powerful and easy-to-use tool that lets you convert complex airfoil images, including those with icing, into precise coordinate files.

The image demonstrates a real-world use case: a NACA 0012 airfoil with upper-surface ice accretion digitized using Airfoil Digitizer. The original airfoil and the iced version are both captured from the image and converted into coordinate data for use in aerodynamic analysis tools such as VisualFoil, Stallion 3D, or even your own custom CFD code.

Why Use Airfoil Digitizer for Iced Airfoils?

• Handles Irregular Shapes: Ice accretion rarely forms smooth contours — our tool adapts to jagged and asymmetric formations.
• Adjustable Tolerance: Capture just the right amount of detail using the built-in tolerance slider.
• Output in Analysis-Ready Format: Export coordinates directly to VisualFoil, UIUC, or DXF format for quick analysis.
• No Need for Manual Tracing: Save time and reduce error when extracting data from icing simulation or wind tunnel images.

Whether you're working on aircraft certification, research, or student projects, Airfoil Digitizer makes it easy to extract the effects of ice accretion for aerodynamic simulation and performance prediction.

Which Software is Used for Aerodynamics and Airfoil Testing

 

3 Classical Aerodynamics Methods in VisualFoi 5

The Three Solvers Behind VisualFoil 5: Powering Accurate Airfoil Analysis

VisualFoil 5 by Hanley Innovations is a powerful software tool for airfoil performance analysis, widely used by aerospace engineers, students, and designers. At the core of VisualFoil 5 are three distinct solvers, each offering a unique balance of speed, accuracy, and physics fidelity.  They are 1. Thin airfoil theory (the blue solution); 2. Inviscid panel method (the green solution); 3. Viscous panel method (the red solution).

1. Thin Airfoil Theory

This is the fastest method in VisualFoil 5, based on classical aerodynamic theory. It assumes an infinitely thin cambered airfoil and linear flow, making it ideal for quick estimates of lift characteristics such as:

• Lift curve slope
• Zero-lift angle of attack
• Center of pressure location

While it doesn't account for viscosity or airfoil thickness, it’s perfect for educational use and early-stage conceptual design.

2. Inviscid Panel Method

The panel method in VisualFoil 5 models the airfoil surface with discrete panels and solves for the velocity potential flow around it. This inviscid (non-viscous) approach captures:

• Pressure distribution
• Streamlines
• Lift and moment coefficients
• Enable contour plots of the flow field

It includes thickness effects and provides higher fidelity than thin airfoil theory. However, it does not predict flow separation or stall, as viscosity is not modeled.

3. Viscous Panel Method (Boundary Layer-Coupled)

The most advanced solver in VisualFoil 5 couples the panel method with a boundary layer model to include viscous effects. This hybrid approach predicts:

• Stall onset
• Drag due to skin friction and separation
• More accurate lift and moment at higher angles of attack

It is ideal for analyzing real-world airfoils where flow separation and drag matter, including thick airfoils like the NACA 0018.

---

In summary, VisualFoil 5 gives users the flexibility to choose the right solver for their analysis—from quick theoretical estimates to high-fidelity, viscous simulations. This versatility makes it a powerful tool for aerodynamic design and education alike.

Aerodynamics simulation software for airfoil and wing

 

3DFoil results compares well with experiments from 

N.A.C.A Report No. 647, 1938, Figure.[1].

We used 3DFoil to perform aerodynamic simulations for a rectangular wing based on a NACA 0012 airfoil. Results were compared with a NACA experiment performed in 1938, Ref. [1]. NACA tested a full sized wing with a span dimension of 36 feet and chord of 6 feet. The tests were performed in a full scale wind tunnel. We compared the results of 3DFoil, our vortex lattice package, against the experiments conducted on the NACA 0012 version of the wing. The results show excellent agreement between 3DFoil and the experiments for the lift and drag coefficients.
