Abstract
Dynamic Structures and Materials, LLC (DSM), the NAWC Chinalake, and ATK share the vision of a Solid Divert and Attitude Control System (SDACS) with the stability and long storage capabilities of a solid fuel system and the versatility of a liquid fuel system. DSM proposes the development of a high specific power (HSP) piezoelectric motorized actuator to command the valves for this system. The proposed actuator makes use of novel gripping concepts and high speed power electronics to enable a 600 Watt PZT-motor actuator. DSM uses the high power capabilities of a PZT stack vibrating at over 10 kHz to produce a macro-continuous motion at lower frequency, yet much greater stroke than possible with direct drive PZTs. The proposed PZT-motor actuator is being designed to produce a 500 lbf stallforce, over 12 in/s speed, no power hold, low EMI interference, increased reliability, and potentially lower cost than current electromagnetic actuators. DSM will develop the motorized actuator and efficient driving electronics for the SDACS and related applications in the Phase II effort. The actuator system will be targeted at driving the valves for a modified 600 lbf sea level divert system, with scheduled cold gas testing on ATK's testbed.
