Due to exposure to extreme temperatures, especially near turbines or during sudden lightning strikes, the material composition can deteriorate. This exposure can result in changes to the material's properties, such as its electrical conductivity. The SIGMATEST device helps measure the conductivity in specific locations or parts, allowing for the identification and replacement of deteriorated components.

Challenges in aviation: Extreme temperatures and structural integrity

In the dynamic world of aviation, ensuring that aircraft are not only efficient but also safe is essential. However, this safety is often threatened by a persistent challenge: extreme temperatures. Particularly near turbines or during sudden lightning strikes, temperatures can often exceed tolerable limits. These extreme heat conditions can have devastating effects on the structural integrity of aircraft, especially on the aluminum components that form the mainstay of the aircraft structure.

The consequences are serious: prolonged exposure to extreme temperatures can cause aluminum to lose its structural strength, endangering the safety of the aircraft. Therefore, addressing these temperature fluctuations is an urgent challenge to ensure the safety of passengers and crew.

Only through a robust and resilient structure can aircraft withstand the rigors of flight operations and ensure the protection of their occupants. It is of utmost importance to address the problem of extreme temperatures and their impact on structural safety with an appropriate approach.

Material properties and their changes at high temperatures

When considering the effects of extreme temperatures on the structural safety of aircraft, it is essential to understand the changes in material properties that can occur at high temperatures. Heat can induce various physical changes in materials, including a significant change in their electrical conductivity. These changes not only indicate the thermal stress to which the material has been exposed but can also serve as precursors to structural damage that could compromise the aircraft's safety.

To effectively assess the structural integrity of aircraft and ensure that they can withstand the rigors of flight operations, strict test specifications are crucial. These specifications are defined by aircraft manufacturers and include precise test points distributed along the aircraft structure, as well as predefined electrical conductivity values that serve as references.

By systematically checking the electrical conductivity at these predefined test points, maintenance teams can identify potential structural issues early and take appropriate measures to ensure the safety of the aircraft. If the measured conductivity is outside the defined tolerance limits, immediate actions such as repair or replacement are required to restore and ensure the structural integrity of the aircraft.
