RotoArray Immersion C-Scan System

The RotoArray is a portable, manually operated, phased array, ultrasonic inspection device which can be connected to any suitable phased array flaw detection instrument to allow rapid scanning of a wide variety of materials and components.

Well suited for scanning composite and aluminum aerospace components, the RotoArray can provide A, B & C-scan images that are achieved with the simplicity of a handheld probe and with performance rivaling that of a full immersion C-scan system.

The RotoArray can complement or replace immersion scanning systems in a manufacturing environment, while being equally functional inspecting in the field or laboratory. It is ideal for scanning aircraft on the ground for collision damage, post-repair and other inspections.

The compact and lightweight RotoArray can be configured for left or right hand operators. The RotoArray consists of a linear, 64 element ultrasonic array contained within a tire, which is inflated with a fluid to create a flexible coupling chamber between the array and the test piece. The tire is fitted within a scanning cart and the complete assembly is rolled along the surface to be inspected to scan for flaws, delaminations, or other discontinuities. An innovative direct-drive magnetic encoder, which operates without belts, pulleys or gears, provides positional data and is connected to a phased array flaw detector, such as GE’s Phasor XS, which displays and stores the results. A panel of three switches with associated cables is available to remotely operate features such as “scan-start”, ”scan- stop”, “scan-clear”, and “scan-index” on suitably equipped instruments.
