This patent describes an attachment structure for attaching a turbine blade to a rotor of a gas turbine engine. It comprises first and second male members spaced axially along and extending circumferentially about each respective rotor blade, means attached to a rotor spool defining first and second grooves spaced axially along and extending circumferentially about the rotor spool and opening in a common axial direction; and means for removably locking the second portions of the male members in mated relation with the grooves to thereby restrain the turbine blade against radial and axial movements relative to the rotor spool.
