The IRT is a closed-return, atmospheric-type wind tunnel that is refrigerated for all-year operation. It is 6 ft. x 9 ft. x 20 ft.

The Icing Research Tunnel may be an historic landmark, but it’s on the cutting-edge of research.

Quick Facts

The IRT has played a substantial role in developing, testing, and certifying methods to prevent ice buildup on aircraft.
