Active Shock Damper Actuator

This was a technology demonstrator that flew on a university Cubesat satellite. The technology was used to damp motion of the spacecraft after momentum events such as solar array deployment. Active dampers are used in tall buildings to lessen the effects of building sway. This was a unique test on a small satellite.

Side Flex Latch Nitinol Actuator

This prototype actuator provided actuation along the narrow axis of the actuator. The idea was to use the music wire flexures as biasing springs and to make it as thin as possible. It is capable of developing roughly 1 pound of force without exceeding a design limit of 25 ksi for high cycle capability. Dynalloy recommends 25 ksi as their “million cycle” force for Flexinol.
