Icing Research

At NASA Glenn Research Center, “We Freeze to Please”. Our icing research teams utilize a refrigerated wind tunnel, an engine test cell, and small scale laboratories to create icing conditions for models and airfoils on the ground, as well as flying laboratories to study aircraft icing in the sky. They have also developed software tools … Continued
