A Flayer about ISU-IRT

ISU Usage rate (updated on 06/01/2024)

 

Icing Research Tunnel of Iowa State University (ISU-IRT), which was donated by UTC Aerospace System (former Goodrich Inc.) to ISU in 2010, is a newly refurnished, research-grade icing wind tunnel. ISU-IRT is a multi-functional icing research tunnel. It can be run over a range of test conditions from rime ice to extremely wet glaze ice, which can be used to duplicate/simulate icing phenomena over a range of conditions for icing physics studies pertinent to aircraft/aero-engine/power transmission line/wind turbine icing and various anti-/de-icing applications. 

 

The working parameters of ISU-IRT are:

  • Test section size:                 W X H X L = 400mm (height) by 400mm(width) by 2,000mm (length);

  • Airflow speed:                     Vair = 5 to 60 m/s;

  • Airflow temperature:         Tair = -25oC to 20oC;

  • Water Droplet Size:            d = 10 ~ 100 micrometers;

  • Liquid Water Content:        LWC = 0.1 to 5.0 grams/cubic meter.
