What is "engine icing" in the context of turbine engines?

In the context of turbine engines, "engine icing" specifically refers to the formation of ice on engine components. This phenomenon can occur during flight when moist air passes through the engine, particularly under conditions of high humidity and cold temperatures. When this moist air comes into contact with the cold surfaces of engine components such as the compressor and turbine blades, it can lead to ice accumulation. This ice can disrupt airflow, reduce engine performance, and pose serious safety risks, as it affects the aerodynamic properties of the engine parts.

The focus on engine components is crucial because ice can lead to several problems, such as reduced thrust and potential engine stalls. Therefore, understanding and mitigating the effects of engine icing is vital for ensuring the reliable operation of turbine engines, particularly in adverse weather conditions.
