Features :

  • Outer shaft with face plate and slip ring stack
  • Central shaft with central plates and slip ring stack
  • Inner shaft for stationary operations, allowing central plate extension during flight
  • Rigid base frame with rotating head, allowing drum to rotate from axis horizontal position to axis vertical position during flight
  • Clutch operations allow central plate to be de-coupled from face plate. Once stationary, extension to drum contaminant lid allows introduction of stationary components to central plate. When again rotating these components can interact with rotating face plate.
