1. A blade for a gas turbine engine comprising
a body including a root configured to engage a turbine rotor, an airfoil extending from the root, and a receiver positioned distally from the root, and a floating blade seal received in the receiver such that centrifugal force applied to the floating blade seal during rotation of the blade about an axis of rotation causes the floating blade seal to move relative to the body and seat against the receiver to extend a radial height of the blade. |
