EloWheel – RPT17 Aircraft Wheel Inspection System

EloWheel – RPT17 Aircraft Wheel Inspection System

Our new RPT17 Aircraft Wheel Inspection System is developed and manufactured in Germany. The system is the successor of the RPT16 – which is fabricated in the US and still placed on the market – and provides numerous innovations. Aircraft rims are are exposed to high mechanical loads, especially during take-off and landing. Additionally enormous thermal stresses occur while applying the brakes after touching down. Thus rims of both, civil aircrafts as well as military aircrafts, have to be inspected for any damages according to the regular maintenance intervals. Regions of maximum stresses, e.g. the bead seat radius and the bore holes, are of special interest. Using a modern eddy current testing instrument, the surface as well as the volume of the wheel rims is inspected by both, a high frequency and a low frequency probe simultaneously.

Features:

3 Versions available
  • stand alone (basic version) with flat turn table
  • version with conveyor rollers on the turntable, for easy integration into an existing conveyor line (with manual feeding of the wheel rims)
  • version with automized conveyor rollers on the turn table, for easy integration
    into an automatic conveyor line (automatic feeding and unloading of the wheels)
  • robust welded steel section frame with four solid screw-in feet (to be used to adapt the system to the height of the existing conveyor belt)
  • removeable side panels
Inspection of Surface Cracks
  • sliding differential aircraft wheel probe featuring approx. 10 mm (0.39″) active area
  • area of inspection: all the way up to the end of the bead seat radius
  • reference defect: depth 0.76 mm (0.03″) x length 1.52 mm (0.06″) x width 0.1 mm (0.004″);
    EDM notches, tangentially and axially oriented
Inspection of Hidden Cracks
  • sliding absolute aircraft wheel probe (combined with the surface probe)
  • area of inspection: up to the beginning of bead seat radius
  • inspection of “break key” section
  • reference defect: approx. 25 % reduction of wall thickness (from the inside)
Use of Latest Software Components
