A locking device (120) for use in a rotor blade, said locking device (120) comprising: a locking member (126) that is arranged to be movable from an unlocked position to a locking position upon experiencing sufficiently fast rotation; and a selectively engagable retaining device (122) arranged when engaged to retain the locking member (126) in the unlocked position. The locking device (120) will typically default to an unlocked position during normal rotation and will only be locked so as to prevent movement when the retaining device (122) is de-activated. A method of locking an actuator (102) is also disclosed. The locking device (120) has applications in helicopter rotor blades and wind turbine blades amongst others. |
