Abstract
A locking device (36) for use in retaining an assembly of rotor blades against movement around a rotor disc on which they are mounted comprises a body member having first and second portions interconnected by a weakened region (66) whereby a force applied to turn the first portion (38) relative to the second portion (40) can cause them to shear apart at said weakened region (66) thereby facilitating release of seized devices to enable blade removal.
Claims20
A locking assembly comprising a locking device comprising a weakened region;
- a first article;
- a second article comprising a recess;
- the locking device being securable in a secured condition in the recess to lock the first article to the second article, wherein a force can be applied to the locking device to break the device at the weakened region to release the locking device from the secured condition thereby allowing the first article to be removed from the second article, said locking device including a body member and securing means to secure the locking device to the second article, wherein the weakened region extends across at least one of the body member and the securing means between a portion of the securing means and a portion of the body member and a force applied to effect relative turning movement of the first portion relative to the second portion will cause the first portion to shear relative to the second portion at the weakened region and to separate therefrom.
