Detecting Clouds Associated with Jet Engine Ice Crystal Icing [PDF]

open access: yesBulletin of the American Meteorological Society, 2019
AbstractIn the past two decades, more than 150 jet engine power-loss and damage events have been attributed to a phenomenon known as ice crystal icing (ICI). Ingestion of large numbers of ice particles into the engine core are thought to be responsible for these events, which typically occur at high altitudes near large convective systems in tropical ...
