In our first installment of “Two Minute Tuesday” we have a two-minute video description of a humidity chamber and the role it plays in aircraft wire evaluation. We also take a look at testing one aspect of an aircraft wire – its ability to withstand variations in humidity and temperature.
The long-term reliability of aircraft components is critical to airworthiness and the ability to maintain component reliability in various aircraft environments is key to achieving this goal. Different parts of the aircraft are subjected to different temperature variations and humidity conditions. The wire and connectors in the wheel well or leading/trailing edges of the wings are subjected to the weather. The video shows a humidity chamber, what wire/cable properties are stressed, how they are assessed, and what that might mean for the reliability of the component over 20-30 years.
By evaluating how these wires perform when placed under thermal and moisture stresses, we can identify the best product for the application.
