Phoenix WrapIt Flexible PA Scanning Tool
The Phoenix WrapIt is a flexible ultrasonic phased array tool that can be wrapped around a curved surface to quickly inspect along a 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.

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
WrapIt is a conformable probe designed for the inspection of radii and curved surfaces. At the centre is a truly flexible ultrasonic phased array transducer that operates on both concave and convex surfaces.
Surrounding the array is a two-part rubber enclosure that is set to a nominal curvature. The rubber housing is adaptable and functionally it confines the flexibility in order to protect the array from potential damage of being over-flexed.
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 panel cut outs 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 couplant irrigation channels that feed water to the front face of the probe providing consistent continuous coupling of the ultrasound.
