Rotor Overspeed Test Set

ROTOR OVERSPEED TEST SET SEA KING HELICOPTER

rotoroverspeedtest

The Overspeed Test Generator (OTG) is designed for use with the two overspeed trip units on the Rolls Royce Gnome engine Sea King helicopter to enable a pre-flight on-ground check of the engine governor system.

The OTG generates a fault in the overspeed governers thus forcing the governors to trip and ensuring the system is fully functional prior to flight. This minimises the risk of over-stressing the rotor hub pitch bearings that could, if severe enough, cause rotor separation from the aircraft.


FEATURES

  • The unit is supplied with inter connecting cables and has an internal battery fitted.
  • Operation of the test set is by means of four toggle switches and two indicator lamps, 6-way socket and a milliammeter. The socket enables the test point outlets to be monitored on the engine.
  • Approved by the UK MOD & Westland Helicopters (UK).
