Flexible Phased Array Scanning Tool

WrapIt is a flexible ultrasonic phased array probe that conforms to the shape of the component.

A flexible array transducer is housed in a rubber enclosure that both protects and pre-forms the array, allowing adaptability to scan parts with changing curvature.

Typical applications for WrapIt include curved composite laminates found in:

  • Aerospace: wing spars, aerofoils, stringers, leading-edge
  • Marine: mast, hull, rigging, rudders
  • Wind Energy: blade spar, leading-edge
  • Motor Racing: aerodynamic components

The array can be easily interchanged between rubber housings to scan different radii. Every housing is suitable for inspecting a range of radii without any mechanical adjustment required.

Attached to the WrapIt is a wheel encoder positioned to run on the radius so it is clear of the panel cutouts and gaps. The high-resolution encoder is waterproof and sprung loaded onto the part giving a stable and reliable operation.

WrapIt incorporates low friction plastic skids to provide stability and a smooth scanning motion.

Within WrapIt, between the array transducer and the component is a flexible rubber delay line. This is accompanied by coupling irrigation channels that feed water to the front face of the probe providing consistent continuous coupling of the ultrasound.

Phoenix ISL WrapIt - Ultrasonic Flexible Array Tool


  • Flexible array transducer for use on concave or convex radii
  • Rubber housing set to nominal geometry limits the variation for protection against accidental damage
  • Spring-loaded waterproof wheel encoder. IP68 rated
  • Encoder Resolution: 65.6 steps/mm
  • Frequency 1—10MHz
  • Number of elements 8, 16, 32, 64, 128
  • Element pitch 0.3—2mm
  • Minimum bend radius is dependent upon the frequency and size (e.g. 5MHz; 1mm pitch achieves ±R15mm; 10MHz, 0.3mm pitch achieves ±R3mm)


  • Conforms to the shape of the component or inspection surface
  • Simple inspection setup as the probe is always normal to the surface
  • No adjustment is needed when scanning a changing radius
  • Cost-effective for multiple geometries as a single transducer can be used in several housings
  • Compatible with standard phased array instruments
