GEMeasurement & Control

RotoArrayTM

The RotoArray is a portable, manually

operated, phased array, ultrasonic

inspection device which can be

connected to any suitable phased

array aw detection instrument to

allow rapid scanning o a wide variety

o materials and components.

Well suited or scanning composite and

aluminum aerospace components, the

RotoArray can provide A, B & C-scan

images that are achieved with thesimplicity o a handheld probe and with

perormance rivaling that o a ull

immersion C-scan system.

The RotoArray can complement or

replace immersion scanning systems

in a manuacturing environment, while

being equally unctional inspecting in

the eld or laboratory. It is ideal or

scanning aircrat on the ground or

collision damage, post-repair andother inspections.

System Description

The compact and lightweight RotoArray can be conguredor let or right hand operators. The RotoArray consists o alinear, 64 element ultrasonic array contained within a tire,which is infated with a fuid to create a fexible couplingchamber between the array and the test piece. The tire istted within a scanning cart and the complete assembly isrolled along the surace to be inspected to scan or faws,delaminations, or other discontinuities. An innovativedirect-drive magnetic encoder, which operates without belts,pulleys or gears, provides positional data and is connected toa phased array faw detector, such as GE’s Phasor XS, whichdisplays and stores the results. A panel o three switches

with associated cables is available to remotely operateeatures such as “scan-start”, ”scan- stop”, “scan-clear”,and “scan-index” on suitably equipped instruments.

Key Benefts

• Is so portable that it puts the power o an immersionC-san system in the palm o your hand

• Is quick and simple, with minimal setup

• Replaces or compliments ull immersion tank andsquirter system scanning

• Provides ast and reliable portable scanning, withA, B and C-scan data

• Is light weight and ergonomically designed, withtorque resistant grips which can be adjusted orlet-hand and right hand operation

• Standard models are available with 3 connectors: Tyco (Phasor XS™), Ipex (Omniscan™) andHypertronics™ (Tomoscan ™, UTXX ™, etc) andother connectors can be custom ordered

• Is supplied with a Service Station to allow usersto carry out simple repairs and congurationadjustments, such as tire replacement and airpurging without actory assistance

• Features easy coupling with no need or complicatedirrigation systems

• Is supplied with a comprehensive digital guide

• Features a unique, direct-drive encoder with no belts,pulleys or gears assuring backlash-ree reliability

• Platorm is designed to be scalable and arrays can becustomized to solve new applications.

RotoArray is supplied with a comprehensive digital guide,that careully and simply explains the system’s capabilities,operation and maintenance using tailored video tutorialsand pictures.

In addition, the RotoArray Service Station allows users

to maximize system up-time by providing a customizedworkbench and the relevant tools to carry out routinemaintenance and repair.

The rst standard versions o the RotoArray scanningplatorm are designed primarily or the inspection o aerospace materials such as composite and aluminum,although the platorm can be used or faw detection andthickness measurement in a wide range o materials.GE will continue to support and nurture urther potentialapplications as they are identied.

Composite and aluminum materials nd their majorapplication in the aerospace sector, where strength-weightratios are o great importance. The automotive sector isalso making increasing use o composite structures andassemblies.

The RotoArray can be used or inspection during

manuacturing as well as or the inspection o damage o aircrat in service.

In manuacturing, the RotoArray can be used as analternative to existing immersion inspection systems.Examples include inspection o smaller parts and specialparts, or to quickly re-scan areas o interest, which wouldnormally require extensive set-up in an immersion system.Also, it can be used on the fight-line to inspect aircratwhich have been damaged in slight collisions, or examplewith baggage carts. In either case, the inspector canobtain reliable and meaningul inspection data to allow the

correct decisions to be made regarding the disposition o the part or aircrat.

Rapid Scanning o Composite Suraces

and Structures

Typical RotoArray Applications

• Inspection o composite plates, stieners and cylinders tocheck or delaminations, porosity, disbonds, etc.

• Providing complementary inspection or composite panels

that have holes through which bubbler or squirter watercan leak causing couplant problems

• Providing enhanced capabilities to scan rom the “rougherside” o composites

• Inspection o composite wind turbine blades

• Inspection o composite aerospace structures, both duringmanuacture and in service

• Inspection o some components which are conventionallyinspected by immersion/bubbler systems

• Inspection o aluminium aircrat skins and other metalstructures or corrosion

• Inspection or faws and corrosion in various metals• Utilizing the fexible rolling core o the RotoArray as the

scanning head in automatic and semi-automaticscanning systems.
