![]() Most ice protection technologies in use today were largely developed at this facility. NASA began icing testing in 1944 with the completion of its Icing Research Tunnel – the longest running and second largest icing facility in the world. Ice on aircraft from 1945 in the Icing Research Tunnel We are challenged to look forward to new technologies being developed and consider what potential issues may arise related to flight into icing. The icing research conducted at NASA leads to developed and validated simulation methods, both computational and experimental, suitable for use as both certification and design tools when evaluating aircraft systems for operation in icing conditions. They have also developed software tools to help predict ice growth and the effects of ice contamination on aircraft or inside of engines. 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.
