Improving Aerospace Safety with PAUT Probes

Posted by VERMON NDT on Mar 5th 2024

Precision and reliability are crucial in aerospace engineering

To ensure the structural integrity of aerospace components, advanced Non-Destructive Testing (NDT) techniques are applied. Phased Array Ultrasonic Testing (PAUT) has emerged as a major contributor to this quest.

In the aerospace sector, Phased Array Ultrasonic Inspection has become widely utilized due to its ability to deliver high-resolution imaging with precise defect characterization, enhancing safety and reliability.


Key Applications of PAUT in the Aerospace Industry

╰┈➤ Composites : PAUT plays a crucial role in inspecting composite materials used in aerospace components, detecting impact damage, delaminations, voids, and disbonds.

╰┈➤ Bolt Holes: Precision is paramount in inspecting fastener holes in aerospace components for detects such as fatigue and stress corrosion cracking, fretting, and corrosion in and around bolt holes. PAUT allows for streamlining inspections compared to traditional methods while offering enhanced precision.

╰┈➤ Turbine Blades : Ensuring the integrity of gas turbine compressors and blades is critical. PAUT accurately assesses turbine blade condition, detecting fatigue cracks and erosion, and can be operated remotely in restricted or hazardous conditions.

╰┈➤ Welds: Critical weld joints undergo thorough inspection with PAUT. It identifies defects such as cracks, porosity, and lack of fusion across the toe, root, and fusion zones using varying beam angles in each of two single-sided scans, negating the need for multiple single-element transducers.

╰┈➤ Aircraft Skin : Aircraft skin undergoes various stresses during flight. PAUT identifies fatigue cracking, corrosion, and hidden defects in the skin, safeguarding structural integrity, even in areas with sealant/interfaces, with fewer scans compared to conventional methods.


Why use PAUT in Aerospace Inspection ?

→ Precision: High-resolution imaging allows for precise identification of defects.

→ Efficiency: Streamlined inspections reduce downtime and enhance operational efficiency.

→ Safety: Early detection of flaws ensures the safety of aerospace components and, by extension, the passengers and crew.
