How does ice accumulate inside hot turbofan jet engines during flight? NASA scientists, working with engine manufacturers, are closer to answering that question
thanks to the only test facility in the world capable of creating a high altitude ice crystal cloud during a full-scale engine test at the Glenn Research Center.
Over the last 20 years, more than 200 incidents have been documented of turbofan jet engines losing power during high-altitude flights, even though pilots observed little to no inclement weather. For many of these incidents, the aircraft were flying in the
vicinity of deep convective storm clouds with only light rain on the windshield. Due to the lack of liquid water content at these high altitudes, it was thought that ice
crystals were hitting and melting on the heated windshields of the aircraft...
