EloWheel – RPT16 Aircraft Wheel Inspection System

EloWheel – RPT16 Aircraft Wheel Inspection System

Manufactured in the US in cooperation with our branch office Rohmann LP, we offer the EloWheel – RPT 16 aircraft wheel inspection system. 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:

Performing Complex Inspections Inspection Tasks:

  • automated detection of surface cracks
  • automated inspection for hidden cracks
  • operation optional from the right, from the left or on the front side

Inspection of Surface Defects
  • 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
  • reference defect: approx. 25 % reduction of wall thickness (from the inside)
