Precision Ultrasonic Inspection for Flight-Critical Structures
Modern aerospace structures rely heavily on composite materials and high-performance alloys that demand rigorous non-destructive evaluation throughout manufacturing and service life. Ultrasonic C-scan and phased array inspection are the industry-standard methods for detecting internal defects in CFRP/GFRP laminates, bonded joints, engine components, and airframe structures. CCNDT provides automated C-scan systems and phased array instruments tailored to aerospace quality requirements, ensuring reliable defect detection from raw material verification to in-service maintenance.
Composite Material Inspection
Carbon fiber and glass fiber reinforced polymer composites are widely used in wings, fuselage panels, tail assemblies, and radomes. These multi-layered structures are susceptible to delamination, porosity, fiber waviness, and impact damage that are invisible on the surface. Automated ultrasonic C-scan with immersion or squirter coupling provides full-area coverage and produces intuitive plan-view images that map defect location, size, and depth within the laminate.
- Detects delamination, porosity, disbonds, fiber waviness, and foreign object inclusions
- Automated C-scan systems with contour-following capability for curved airframe parts
- Compliant with ASTM E2580, GB/T 44525, and aerospace OEM specifications
- High-resolution imaging enables ply-level defect characterization
Engine Component & Turbine Blade Testing
Turbine blades, discs, and compressor components operate under extreme thermal and mechanical loads, making internal flaw detection critical to flight safety. Ultrasonic testing identifies subsurface cracks, voids, and inclusions in nickel-based superalloys and titanium forgings before they propagate under cyclic loading. Phased array inspection provides cross-sectional imaging of complex blade geometries without destructive sectioning.
- Inspection of turbine blade roots, fir-tree attachments, and cooling channels
- Detection of fatigue cracks, creep voids, and casting defects in superalloy components
- Phased array sector scanning for complex-profile turbine parts
- Supports both manufacturing QA and MRO (maintenance, repair, overhaul) workflows
Airframe Structure & Fastener Hole Inspection
Metallic and hybrid airframe structures require periodic inspection of fuselage skins, wing spars, bulkheads, and thousands of fastener holes for fatigue cracking and corrosion. Ultrasonic pulse-echo and through-transmission techniques detect cracks initiating at bolt holes, rivet lines, and structural joints. Automated scanning systems significantly reduce inspection time while improving repeatability compared to manual methods.
- Fastener hole crack detection using bolt-hole eddy current and ultrasonic combined approaches
- Fuselage skin lap-joint and bond-line integrity assessment
- Corrosion mapping in multi-layer metallic structures
- Traceable digital records supporting airworthiness compliance and fleet management
