ICED-CRM Testing Successfully Completed Through International Collaboration

Wind tunnel tests led by Cranfield University as part of the ICED-CRM project have been completed, examining the aerodynamic effects of leading edge and runback ice shapes on the NASA CRM high-lift model.

The project brought together Airbus, Boeing, NASA, Cranfield University, and the European Transonic Wind Tunnel (ETW), with testing showing excellent agreement with NASA NTF baseline data.

Tests of Boeing (Appendix C) and Cranfield/Airbus (Appendix O) ice shapes were successful. The project provides the first high Reynolds number dataset for simulated Appendix O icing effects. It also represents a unique collaboration between Boeing, Airbus, and UK academic researchers.

Data will be made available via NASA’s CRM data portal and the NWTF Experimental Database.

Two groups of NWTF-sponsored academics visited during testing to learn more about cryogenic testing, aircraft icing and the NASA CRM ecosystem.

Thank you to Prof Simon Prince, Cranfield University, ETW, and the wider ICED-CRM team for their support.
