Ice Crystal and Mixed Phase Icing Tunnel Testing of Air Data Probes
AIR6974
This document provides information on current practices for testing air data probes to 14 CFR Part 33 Appendix D ice crystal and mixed phase icing conditions. This AIR is primarily concerned with techniques for measuring the flow and icing environment in the test facility. While the focus of this report is the testing of air data probes, techniques described may be applicable to Appendix D tests of other aerospace equipment as well.
Rationale: This SAE Aerospace Information Report provides in one location, comprehensive information on current practices in testing air data probes to 14 CFD Part 33 Appendix D ice crystal and mixed phase icing conditions. The practices outlined in this document are current state-of-the-art for conducting qualification testing of air data probes in the relevant environments.
