Abstract
A rotor () for a gas turbine engine () has a low emissivity surface finish, or high emissivity surface finish (), on at least a portion of its surface () to reduce temperature differentials between an upper portion and a lower portion of the rotor (). This reduces bowing of the rotor () to allow the gas turbine engine () to be started without harmful vibrations of the rotor ().
