Abstract

A system for modulating turbine blade tip clearance (201) is provided. The system may comprise an actuation control system (200; 300; 500) having at least one actuator (210) configured to modulate turbine blade tip clearance (201). Each actuator (210) may comprise a solid-state motion amplification device such as a flextensional actuator. Each actuator (210) may be in operable communication with a blade outer air seal (BOAS) segment or a BOAS mounting block. The actuators (210) may be configured to move the BOAS segment and/or the BOAS mounting block in a radial direction from a first position to a second position to control tip clearance (201).
