A project log for Fluid Displacement Thermal Actuators

Actuators that use a hydraulic medium to transfer material phase displacement as a thermally reactive mechanical force

For the next iteration of the design, I decided to machine a basic FDTA out of Aluminum. Previous versions of the device have been made out of glass or acrylic to allow visual inspection of the PCM. Now that I have experience with machining Aluminum, I can explore higher pressures than were possible with glass. I designed this actuator around some scraps I had in my shop, with a usable stroke of approximately 40mm.
