In operation since 1944, the Icing Research Tunnel is the oldest and largest refrigerated icing wind tunnel in the world. Technology developed there enables aircraft to fly safely through icing clouds. Two firsts include the unique heat exchanger and the spray system that simulates a natural icing cloud of tiny droplets.
