- In-flight ice affects jet engines differently than reciprocating engines. For the most part, the problems involve damage to rotating components or disruption of the airflow through the engine and accompanying engine stalls or stagnations. Structural ice which forms ahead of or in the inlets can be shed in slabs which, if they enter the engine, can cause damage to the engine and loss of thrust. In addition, if the slabs disrupt the airflow across the compressor face, compressor stall, which results in engine flameouts or stagnation, can also occur. The formation of ice on inlet guide vanes, stators, and compressor blades can result in reduced clearance and interference damage. Post-crash evidence may include FOD-type damage. Engine stagnation can lead to excessive temperatures in the engine’s turbine section and associated heat damage. Finally, modern jet engines rely on pitot-static pressure information from the engine inlet. If the sources of this pitot-static pressure information are iced over, engine operation and thrust output can be affected. Evaluation of FDR and CVR data may provide clues concerning engine RPM, thrust produced and operation of de-ice or anti-ice systems.
