| Résumé | Small borescope cameras made it possible to observe ice accretion within the tight geometric confines in the ICE-MACR (Ice Crystal Environment Modular Axial Compressor Rig). Previous review of the videos classified accretion behavior qualitatively according to a severity scale, where severity 3 indicates maximum threat to an engine. This paper describes methods used to analyze the digital video recordings. The technique provided quantitative data such as tracking the occurrence, extent and frequency of leading edge ice shedding. A method of summarizing accretion for quick reference is presented, without superseding the value of watching the videos for severity classification. This work allows direct comparison of time-series analog data with the video recordings, and should prove a useful tool to researchers analyzing accretion video. |
