A number of recent turbofan failures during aircraft transit through apparently benign regions of storm clouds at high altitude have been attributed to a previously unrecognised form of icing. In this new form of icing, water in the solid phase enters the engine and builds up on the early stages of the compressor. A small wind tunnel has been developed to investigate the physics of solid phase ice accretion at thermal conditions relevant to turbofan operation during transit through high altitude clouds. The design and operation of the wind tunnel facility is described and thermodynamic and aerodynamic performance of the facility is characterized through temperature, pressure, and flow rate measurements. Operational characteristics and limitations of the wind tunnel facility are discussed. Preliminary ice accretion results indicate that configuration changes are necessary to ensure that all of the water impacting on the model surface is ice.
