Abstract

A system for modulating turbine blade tip clearance (201) is provided. The system may comprise an actuation control system (200; 300) having at least one actuator (210) configured to modulate turbine blade tip clearance (201) between a turbine blade tip (192) and a blade outer air seal (BOAS). Each actuator (210) may be coupled to the BOAS. Each actuator (210) may comprise a solid-state motion amplification device such as a flextensional actuator. The actuators may be configured to move the BOAS in a radial direction from a first position to a second position to control tip clearance (201).
