Title: Reliable Actuator for Cryo Propellant Fluid Control
Agency: NASA
Contract: NNX12CE83P
Award Amount: $124,995.00


Cryogenic fluid handling applications require a reliable actuation technology that can handle very low temperatures. 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, reduction of heat load, and lower cost as compared to traditional electromagnetic actuators. Dynamic Structures and Materials (DSM) proposes to focus the Phase I 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 already demonstrated 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 outgassing 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.
