Abstract
Turbine and other bladed disc assemblies and associated methods are disclosed. In an embodiment, a turbine assembly includes a rotor and a turbine disc secured to the rotor via a nut and a deformable retainer. The nut is threadably engaged with the rotor to secure the turbine disc to the rotor. The retainer is deformed to co-operatingly engage with a periphery of the nut and configured to hinder rotation of the nut relative to the rotor.
