Definitions

  • the control electronics 130 and therefore the operation of the motor 110, is preferably controllable from a remote control.
  • This remote control enables a single operator to control the rotation of the rotor and, simultaneously, to carry out the inspection of the parts of the turbojet engine, for example using an endoscope. It is for example equipped with an on/off button, a potentiometer for adjusting the speed and/or the direction of rotation of the motor, a button for memorizing the position of the rotor (reference point) and an "emergency stop" button.
  • the drive system according to the invention is particularly easy to use. Its installation on a turbomachine rotor does not require any prior dismantling, since the rotor blades are accessible to the operator. For the same reasons, removing it from the rotor is just as quick and easy. It is also light and compact, which makes it easy to handle by one person.
  • its maximum dimension here the length
  • the wheel 120 has for example a diameter of 9 cm for an outer casing of 195 cm in diameter.
  • the tread 121 measures for example 3.5 cm in width.
