A rotor assembly, particularly for a gas turbine engine, comprising a torsionally stiff drive shaft 16 mounted at two spaced locations in first and second bearings 22,23 which are substantially immovable bodily in radial directions. The drive shaft 16 has a flexible end portion 15 constituted by a shaft 25, projecting beyond the first bearing 23 which is more flexible in bending than the span of the drive shaft 16 between the first and second bearings 22,23. A support means 27 is mounted for rotation in a third bearing 28. The rotor 11 is mounted on the ...
