International ClassF01D 005/08Foreign Application Priority Data1999-03-27 GBAbstractA rotor (38) for a gas turbine engine (10) has a low emissivity surface finish, or high emissivity surface finish (44), on at least a portion of its surface (42) to reduce temperature differentials between an upper portion and a lower portion of the rotor (38). This reduces bowing of the rotor (38) to allow the gas turbine engine (10) to be started without harmful vibrations of the rotor (38).Field of SearchSpecific casing or vane materialMeans subjected to or is working fluid INCLUDING HEAT INSULATION OR EXCHANGE MEANS (E.G., FINS, LAGGING, ETC.)
