Composite rotor blade attachment in a gas turbine

摘要

A rotor blade (24) for a gas turbine engine (10) includes an airfoil (28) that extends in span between a tip (30) and a root (32) opposite from the tip (30). The root (32) includes a plug (34), a looped portion (36) that surrounds the plug (34) and a clamp (38). The clamp (38) contacts only a portion of the looped portion (36) on an opposite side of the looped portion (36) from the plug (34).
