Borescope Inspection Management for Engine

Visuohaptic borescope inspection simulation training: modeling multi-point collision detection/response and evaluating skills transfer

Results are presented from a transfer effects study of a visuohaptic borescope simulator developed for non-destructive aircraft inspection training. The borescope simulator supports multi-point collision detection to effect haptic feedback as the virtual probe slides along and collides with rigid surfaces. Such probe maneuvering is shown to be a significant aspect of the inspection task that be...

Automatic Deformation Detection for Aircraft Engine Disk Inspection

Computer vision algorithms are seeing increased use in industrial inspection applications. Here, we present an “Aid to Visual” system that can detect post deformations of less than 0.005 inches in jet engine high pressure turbine disks. We create a gold-standard reference post from the posts of sample turbine disks and then use registration, edge detection, and curve-similarity algorithms to id...

Electronic engine management: Key technology for intelligent engine control

Engine control center Legislators all over the world are specifying in­ creasingly tougher emissions limits for diesel engines. To comply with the requirements, emis­ sions from the drive system are constantly being reduced. As the engine’s brain, the engine man­ agement system (see Figure 1) controls key sys­ tems such as fuel injection, turbocharging and exhaust gas recirculation (EGR) that a...

Real time tracking of borescope tip pose

In this paper we present a technique for tracking borescope tip pose in real-time. While borescopes are used regularly to inspect machinery for wear or damage, knowing the exact location of a borescope is difficult due to its flexibility. We present a technique for incremental borescope pose determination consisting of off-line feature extraction and on-line pose determination. The offline feat...
