What impacts does moisture have not just on performance but also on engine components?

Moisture can cause erosive damage to engine components, particularly in turbine engines. When water is present, especially in the form of liquid droplets or vapor, it can lead to several detrimental effects.

First, moisture can contribute to the formation of corrosion on metal surfaces. This corrosion occurs when water reacts with the metal, accelerating degradation and potentially leading to structural failures over time. The presence of moisture can also create an environment conducive to pitting corrosion, where small pits develop on the surface of components, which can eventually compromise their integrity.

Furthermore, moisture can contribute to the erosion of blades and other critical components. As water droplets collide with the high-velocity surfaces of turbine blades, they can wear away material, leading to loss of aerodynamic efficiency and increasing maintenance requirements. This erosion can significantly impact the performance and longevity of engine parts, ultimately affecting the overall functioning of the engine.

In the context of turbine engines, understanding the consequences of moisture is vital, as it informs maintenance practices and operational limits to minimize potential damage and ensure reliable performance.
