AMES, Iowa – In Hui Hu’s Iowa State University office, you can feel exactly what ice does to an airfoil. As he recently rolled through the slides describing his research using Iowa State University’s ...

Though they share similar airfoil shapes, Hu said icing on aircraft wings and wind turbine blades can be quite different. That’s because wings are typically made of metal, have very smooth surfaces ...

These are the angle of attack (AOA) of the airfoil and the airspeed. ... It is time for a simple “Approach In Icing Conditions” procedure, we argue in Part 2 of this article.

In the Icing Research Tunnel of NASA’s Glenn Research Center in Ohio, granular “rime ice” chunks obliterate an airfoil’s smooth surface.

As some scientists search for new anti-icing methods, ... surface dielectric barrier discharge plasma actuators and mounted them on a 3D-printed plastic NACA 0012 airfoil.

The de-icing system works on the basis of allowing ice to form before being broken off ... The amount of lift a wing creates depends on the relative angle that the airstream has to the airfoil.

Environmental factors such as heavy rain, Mach waves, crosswinds, anti-icing fluids, decayed aerodynamic seals and icing induce significant changes on an airfoil’s and/or wing’s stall behavior.
