Revised Low Cost Actuators

The program aims to develop a new compact, high temperature (150░C withstand) operational solid-state actuator technology aimed at hypersonic missile and munition applications that will decrease cost and improve existing actuator performance. These new actuators will meet stall loads of 5000 N, provide an actuation speed of 100 mm/s, and enabling stroke of up to 5 cm. The design will incorporate QorTek advanced TX101 textured ceramic actuation elements delivering strain (displacement) approximately 2 times greater than conventional piezo ceramics. Importantly, TX101 shows no reduction in performance up to 150░C. Further available is our HT301 piezoceramic with even higher operational temperature of 300░C (3 times that of conventional piezoceramics). QorTek will develop an innovative large force/stroke piezoelectric linear motor/actuator incorporating this high temperature material as their active elements. Phase I will focus on simulation and testing of critical subsystems, with a phase I exit of a down selected design, which will be prototyped in Phase II.
