The A06 test facility designed for combustor testing in altitude has been modified to be converted in an icing facility for probe testing. The objective was to be able to simulate ice crystals conditions at high altitude, high Mach number and low temperature. This facility has been upgraded in several steps extending the median size of the ice crystals produced and the ice water content range. The aero-thermal and icing capabilities have been assessed during commissioning tests. Finally, in order to prepare the calibration of the facility, some measurement techniques for cloud characterization have been selected or developed, especially for cloud uniformity measurement.

This paper deals with the development and the validation of a SLD capability in the DGA Aero-engine Testing icing altitude test facility S1 and with the results of the EXTICE 2D SLD icing tests campaign on a NACA 0012 airfoil. A new kind of SLD atomizer has been developed and characterized prior to being installed on the S1 sprays bars for freezing drizzle calibration tests. For 2D icing tests, a specific set-up has been designed and validated. Some results of the SLD atomizer characterization, calibration tests, 2D test methodology validation and EXTICE SLD 2D icing tests are presented.
