Abstract:
There is disclosed an auxiliary rotation device  28  for a gas turbine engine  10 . The auxiliary rotation device  28  comprises: an electric machine  30  configured to be coupled to a rotor of the gas turbine engine  10 ; and a dedicated electrical storage device  32  coupled to the electric machine  30 . During a period of powered operation of the gas turbine engine  10  the electric machine  30  is configured to act as a generator so as to charge the dedicated electrical storage device  32 . Following the period of powered operation of the gas turbine engine  10  the electric machine  30  is configured to act as a motor by discharging the dedicated electrical storage device  32  so as to cause the rotor to rotate for a period of time to provide even cooling of the rotor around its circumference. There is also disclosed a method of cooling a rotor of a gas turbine engine  10  using an auxiliary rotation device  28.

Claim (Index 12):
A method as claimed in  claim 11 , wherein the electric machine automatically begins rotating the rotor following the period of powered operation of the gas turbine engine.
