A ducted fan gas turbine engine (10) is provided with an electric motor starter unit (16). The oil lubrication system of the engine (10) is so arranged that during engine starting, the heat generated by the starter unit (16) is used to heat up the oil in the system. This reduces the viscosity of the oil, thereby facilitating easy engine starting under very cold conditions.
A gas turbine engine provided with an electric starter unit, said starter unit being adapted to provide rotation by direct drive of at least one of the rotatable parts of said gas turbine engine to facilitate engine starting, said gas turbine engine having an oil-based lubrication system, means being provided to place the oil in said lubrication system in heat exchange relationship with said electric motor starter unit, at least during engine starting, to provide an increase in temperature, end consequent decrease in viscosity, of said lubrication system...
