OKO-NDT SMARTSCAN Aircraft Wheel Inspection System (with Eddycon D)

The OKO-NDT SMARTSCAN Aircraft Wheel Inspection System is a comprehensive, automated or semi-automated Eddy Current (EC) solution tailored for the rigorous inspection demands of aircraft main and nose wheels. Developed by OKO-NDT (OKOndt GROUP), this system combines a precision mechanical scanning unit with the advanced capabilities of the Eddycon D multi-channel flaw detector, ensuring highly accurate and repeatable detection of fatigue cracks, corrosion, heat damage, and other critical defects that can compromise aviation safety.

Key Features & Benefits:

• Dedicated Aircraft Wheel Inspection: Specifically engineered for the geometry and materials of aircraft wheels, ensuring thorough coverage of critical areas such as the tubewell, bead seat, and flange. Compatible with a wide range of wheel manufacturers (e.g., Messier-Bugatti, Goodrich, Honeywell, Meggitt).

• Automated/Semi-Automated Operation (SMARTSCAN): The system automates the scanning process, drastically reducing inspection time, minimizing human error, and ensuring 100% inspection coverage. It features mechanisms for:

  • Wheel Hub Grip: Automatically centers and securely grips wheels weighing up to 330 lbs (150 kg).

  • Lifting/Lowering & Rotation: Precisely positions and rotates wheels at adjustable speeds (10-120 rpm).

  • ECP Movement: Automatically moves the Eddy Current Probe (ECP) in horizontal and vertical planes, adapting to the wheel's profile with high precision.

  • Adjustable Inspection Helix: Allows adjustment from 0.1 to 2 mm (0.004 to 0.08 in.) for optimized defect resolution.

• High-Performance Eddycon D Flaw Detector: The integrated Eddycon D is a universal multi-channel eddy current flaw detector, providing:

  • Wide Frequency Range: Operates from 10 Hz to 16 MHz, suitable for diverse materials and defect types. Standard probes typically use 100 kHz, 200 kHz, 500 kHz.

  • Multi-channel Capability: Can manage multiple EC probes for comprehensive and rapid data acquisition.

  • Advanced Signal Processing: Features digital filtering (Low-pass, High-pass, Bandpass), adjustable gain, and various ECP connection capabilities (differential, absolute, transformer type).

  • High Sensitivity: Capable of detecting artificial defects as small as 1.5 mm length, 0.1 mm width, and 0.76 mm depth.

• Intuitive Control & Analysis Software:

  • User-Friendly Interface: Special purpose software for controlling the mechanical parts, setting up EC parameters, real-time data display (time charts, complex plane, 2D display), and results review.

  • Automated Calibration: Performs automated ECP performance validation by scanning a reference block before and after inspection.

  • Data Recording & Reporting: Records all inspection results to a PC hard drive/database, allows for archiving, retrieval, and automated generation of inspection protocols/reports.

  • Defect Management: Features automatic stop-on-defect mode, visual and acoustic alarms, and a "return to defect" function for manual confirmation.

• Safety Features: Includes lockups to prevent excessive force, remote "Pause" button, and ergonomic design for operator safety.

• Compliance: Meets stringent industry standards such as ISO 15548-1, crucial for aviation applications.

• Modular & Robust Construction: Built with high-quality components, ensuring reliability, low maintenance, and ease of serviceability.
