Ultrasonic testing utilizes high-frequency sound waves to inspect materials for flaws. This method is particularly effective for detecting subsurface cracks, voids, and bonding inconsistencies in aerospace materials, including metals and composites.
- Turbine Blades & Rotors: Jet engines rely on precision-engineered turbine blades that must endure extreme heat and centrifugal forces. Ultrasonic inspections help detect stress fractures, voids, and thermal degradation, ensuring optimal performance and safety.
- Composite Structures: Modern aircraft are increasingly constructed using lightweight composite materials. UT helps detect delamination, water ingress, and fiber breakage that could compromise structural integrity.
- Welded & Bonded Joints: Aircraft structures often include welded and bonded components that must withstand immense pressure and vibration. Ultrasonic inspections assess these joints for defects such as lack of fusion, porosity, or inclusions.
X-Ray (Radiographic) Inspections in Aerospace
Radiographic testing (RT) uses X-ray or gamma radiation to capture internal images of aerospace components, allowing inspectors to identify hidden defects without disassembly. This method is crucial for analyzing high-density materials and complex assemblies.
- Aircraft Fuselage & Wings: X-ray inspections reveal hidden corrosion, cracks, and foreign object debris (FOD) trapped within structural cavities.
- Hydraulic Systems & Piping: Aerospace hydraulic systems must maintain leak-free operation under high pressures. Radiographic testing detects blockages, cracks, and wall thickness variations in pipes and pressure vessels.
- Electronic & Avionic Components: X-ray technology is also used to inspect circuit boards, wiring harnesses, and avionics for soldering defects, broken connections, or internal fractures.
