Cost Effective Growth of High Temperature Piezoelectrics for Adaptive Flow Control Actuators, Phase I

Completed Technology Project

Project Introduction

Cost Effective Growth of High Temperature Piezoelectrics for Adaptive Flow Control Actuators, Phase I
TRS Technologies, Inc. in collaboration with The Pennsylvania State University propose to develop new families of high temperature piezoelectric materials for adaptive engine control. The identification, synthesis and characterization of these new materials will enable the design of new high temperature piezoelectric active flow control actuators that may enable dramatic increases in the efficiency of revolutionary alternative propulsion system concepts or the concept designs themselves. Specifically, the objective of the program is to identify materials for high authority (d33 ? 400 pC/N) piezoelectric actuators for fuel flow control in gas turbine engines. The high strain, high force actuators will be operational in the range of 600?1200oF with 1 to 10 kHz capabilities. This will be achieved by synthesizing new piezoelectric in both textured ceramic and single crystal form. The focus will be to use cost effectives methods to produce either textured microstructures or single crystal materials that lend themselves to domain engineering for enhanced piezoelectric performance at elevated temperatures.
