Abstract
A blade locking device, for locking radially projecting blades on a rotor includes a pair of retaining pins having enlarged forward and aft end portions or lugs. The retaining pins are inserted into a radial space between the blade tang and the bottom of the rotor slot. Spacer means maintain the retaining pins circumferentially spaced apart and further maintain the end lugs in confronting and overlapping relationship with forward and aft abutment surfaces on the sides of the rotor and with forward and aft end faces on each end of the blade tang. The spacer means are fixed against axial movement relative to said retaining members. Resilient biasing means can be provided to bias the rotor blade radially outward.
