Abstract
Fluid handling applications in cryogenic and extreme environments require reliable actuation technology that can handle extreme temperatures, mechanical bind-up from ice and foreign contaminants, and operation in poor conditions. A novel EM hammer drive technology is proposed for use in cryo-propellant fuel storage and regulation valves/devices. In addition to high force, the new drive technology offers potential advantages for miniaturization, heat load reduction, and lower cost than traditional electromagnetic and piezoelectric actuators. Dynamic Structures and Materials (DSM) proposes to focus the Phase II innovation on the development of a hammer drive actuation mechanism that will take the EM oscillatory power and produce continuous linear motion for operation at cryogenic and extreme environments. DSM has demonstrated expertise in the operation of its high force linear motor actuators at temperatures down to 77 K. The proposed actuator should operate from approximately 4 K to 400 K and should provide very low or no out gassing as well as operational capabilities in hard vacuum. The technology is proposed for applications in the cryo fluid management, pressure and flow control, and driving operational equipment and instruments. This proposal addresses DSM's approach to the development of flight-scalable demonstration components for the EM hammer drive technology.
