JET Engine Storage

Impact of Uncontrolled Humidity

The storage of jet engines in standby for emergency replacements is a common practice among airline companies. However, the susceptibility of these engines to corrosion while in storage poses a significant operational risk. Uncontrolled humidity in storage rooms is identified as the primary cause of corrosion, leading to potential engine damage and failure.

Consequences of High Humidity

Corrosion of jet engines due to uncontrolled humidity compromises their structural integrity and operational reliability. Ferrous materials, such as iron and steel, are particularly vulnerable to corrosion in the presence of moisture, leading to degradation and potential malfunctions. Additionally, electronic components are susceptible to micro-corrosion, further exacerbating the risk of engine failure.

Additional Effects

The onset of corrosion occurs when relative humidity levels exceed 45%, particularly in polluted air environments. Sudden fluctuations in temperature within storage rooms contribute to condensation on surfaces, accelerating the corrosion process. Without adequate humidity control measures, the cost of maintenance and corrosion mitigation significantly impacts operational expenses.

Causes of Uncontrolled Humidity

Uncontrolled humidity in storage rooms results from the constant presence of water vapor in the air, leading to condensation on metal surfaces. Changes in temperature exacerbate this phenomenon, creating favorable conditions for corrosion initiation and propagation.

Recommendation

Josem advocates for the implementation of humidity control measures to mitigate the risk of corrosion in jet engine storage areas. By maintaining relative humidity levels below 45%, the likelihood of corrosion-induced engine damage can be substantially reduced. This proactive approach not only enhances operational reliability but also minimizes maintenance costs associated with corrosion mitigation.

Solution

Josem advocates for the implementation of desiccant dehumidification solutions to address the challenges posed by uncontrolled humidity. By installing Josem Desiccant Dehumidifiers, airports can maintain precise humidity levels irrespective of external conditions, ensuring uninterrupted signal transmission and operational integrity. This solution, when combined with air conditioning, establishes the requisite humidity and temperature parameters essential for Instrument Landing Systems, thereby enhancing safety and efficiency.
