How does an aircraft hangar deal with aircraft corrosion prevention? - Blog

As a reputable supplier of Aircraft Hangar, I understand the critical importance of aircraft corrosion prevention. Corrosion is a major concern in the aviation industry, as it can compromise the structural integrity of aircraft, reduce their lifespan, and pose significant safety risks. In this blog post, I will discuss how an aircraft hangar can effectively deal with aircraft corrosion prevention.

Understanding the Causes of Aircraft Corrosion

Before delving into the prevention methods, it's essential to understand what causes aircraft corrosion. Corrosion is a natural electrochemical process where metals react with their environment, leading to the deterioration of the metal. For aircraft, several factors contribute to this process:

Moisture: Water is a primary catalyst for corrosion. When aircraft are exposed to high humidity, rain, snow, or condensation, the water can react with the metal surfaces, initiating the corrosion process.
Salt Air: Aircraft operating in coastal areas are particularly vulnerable to corrosion due to the presence of salt in the air. Salt accelerates the corrosion process by increasing the conductivity of the water film on the metal surface.
Chemicals: Exposure to chemicals such as de - icing fluids, hydraulic fluids, and cleaning agents can also cause corrosion if not properly managed. These chemicals can react with the metal and break down its protective coatings.
Galvanic Corrosion: When two different metals are in contact in the presence of an electrolyte (usually water), galvanic corrosion can occur. This is common in aircraft where various metals are used in the construction.

Designing an Aircraft Hangar for Corrosion Prevention

The design of an aircraft hangar plays a crucial role in preventing aircraft corrosion. Here are some key design considerations:

Ventilation: Proper ventilation is essential to control humidity levels inside the hangar. A well - ventilated hangar allows for the exchange of air, reducing the buildup of moisture. Natural ventilation systems, such as ridge vents and gable vents, can be combined with mechanical ventilation, like exhaust fans, to ensure continuous air circulation.
Insulation: Insulating the hangar helps prevent condensation. When warm, moist air comes into contact with a cold surface, condensation occurs. By insulating the walls and roof of the hangar, the temperature difference between the inside and outside air is reduced, minimizing the chances of condensation forming on the aircraft.
Flooring: The hangar floor should be designed to drain water quickly. A sloped floor with a proper drainage system ensures that any spilled water, such as from cleaning or de - icing operations, is removed promptly. This prevents water from pooling around the aircraft, which could lead to corrosion.
Material Selection: The materials used in the construction of the hangar should be corrosion - resistant. For example, steel structures can be coated with anti - corrosion paints or galvanized to protect them from rust. Using non - metallic materials in areas where possible can also reduce the risk of galvanic corrosion.

Maintenance and Monitoring

Regular maintenance and monitoring are vital for effective corrosion prevention in an aircraft hangar.

Cleaning: Regularly cleaning the aircraft and the hangar is essential. Aircraft should be washed to remove dirt, salt, and chemicals that can cause corrosion. The hangar itself should also be cleaned, including the floors, walls, and ceilings, to prevent the buildup of contaminants.
Inspections: Frequent inspections of the aircraft and the hangar are necessary to detect early signs of corrosion. Visual inspections can identify surface corrosion, while non - destructive testing methods, such as ultrasonic testing and eddy - current testing, can be used to detect internal corrosion in critical components.
Coating Maintenance: The protective coatings on the aircraft are crucial for preventing corrosion. These coatings should be inspected regularly and reapplied as needed. Any damage to the coatings, such as scratches or chips, should be repaired immediately to prevent corrosion from starting.
Humidity and Temperature Monitoring: Installing sensors inside the hangar to monitor humidity and temperature levels is a good practice. Maintaining the humidity below a certain level (usually around 50 - 60%) can significantly reduce the risk of corrosion. If the humidity levels rise above the recommended range, dehumidifiers can be used to lower them.

Use of Corrosion - Preventive Products

There are several products available that can help prevent corrosion in an aircraft hangar.

Base Garage

Corrosion Inhibitors: These are chemicals that can be applied to the metal surfaces of the aircraft to slow down the corrosion process. Corrosion inhibitors work by forming a protective layer on the metal, preventing the access of water and oxygen.
Desiccants: Desiccants are substances that absorb moisture from the air. Placing desiccants in the hangar can help reduce humidity levels, especially in areas where ventilation is limited.
Protective Covers: Using protective covers for aircraft when they are not in use can shield them from the elements. These covers can be made of materials that are resistant to water, UV rays, and other environmental factors.

Training and Education

Proper training and education of hangar staff are essential for effective corrosion prevention. Staff should be trained on the causes and effects of corrosion, as well as the proper procedures for cleaning, inspecting, and maintaining the aircraft and the hangar. They should also be aware of the importance of following safety protocols when using corrosion - preventive products.
