Abstract

Gas turbine blades (14) are slid axially into disc (12) with a retention tang (22) on each blade abutting the disc. An axially extending space (18) between blade platforms (26) and the disc receives elongated strip (30). With prebent end (34) resiliently held against the disc the opposite end (36) is bent radially outward against the roots of adjacent blades. A bow (38) biases the blades outwardly, deterring vibration.
