ABSTRACT:
A new capability was developed for indoor simulation of snow and mixed-phase icing conditions. This capability is useful for year-round testing in the Cox closed-loop Icing Wind Tunnel. Certification of aircraft for flight into these types of icing conditions is only required by the JAA in Europe. In an effort to harmonize certification requirements, the FAA in the U.S. sponsored a preliminary program to study the effects of mixed-phase and fully glaciated icing conditions on the performance requirements of thermal ice protection systems. This paper describes the test program and the associated results.

SUBJECT TERMS:
Supercooled large droplets (SLD) icing conditions; ATR-72 accident; Mixed-phase; Glaciated icing conditions; Alliance icing research study (AIRS); Canadian freezing drizzle experiment (CFDE)
