An Overview of NASA Engine Ice-Crystal Icing Research

Ice accretions that have formed inside gas turbine engines as a result of flight in clouds of high concentrations of ice crystals in the atmosphere have recently been identified as an aviation safety hazard. NASA’s Aviation Safety Program (AvSP) has made plans to conduct research in this area to address the hazard. This paper gives an overview of NASA’s engine ice-crystal icing research project plans. Included are the rationale, approach, and details of various aspects of NASA’s research.
