In a locking arrangement for the rotor blades of a gas turbine, a plate 15 extends circumferentially over the roots 3 of several blades. The plates 15 are trapped, in the assembled position, between retaining hooks 13 and 9 respectively integral with the rotor disc 7 and the blade roots 3. The plates 15 each have a resiliently mounted dog 21 which, when in position, prevents rotation of the plate 15. The plate 15 is inserted in one rotational position, by deflection of the dog 21, and then moved rotationally to engage the plate with both sets of hooks and, at the same time to allow the dog 21 to snap into its locking position. The plate covers and seals the gaps between blade roots and rotor disc, the locking is positive and at the same time can be released by depression of the dog. <IMAGE> |
