A stub shaft (101) for a turbine engine is described in which respective masses (104, 105, 106) are positioned along the stub shaft (101) in a balanced rotation relationship for normal rotation. One mass (104, 106) is positioned at the periphery of a shaft end rim (107) such that upon failure of the stub shaft (101) this mass (104, 106) is detached. Such displacement or detachment of the mass (104, 106) causes imbalance which creates vibration which in turn causes surge within a compressor associated with the stub shaft (101) as well as possibly interference engagement with stable structure elements in order to limit turbine and/or compressor over speed. |
