  • SHAPE MORPHING FINS FOR FROST REMOVAL
    Publication number: 20240102751
    Abstract: A shape-morphing fin includes a fixed portion, a multistable portion, a coupling portion, and a vibration source. The multistable portion functions as a negative stiffness element. The multistable portion is selectively movable between a first position and a second position. The movement between first position and the second position is configured to remove the ice formation from the structure. The coupling portion couples the fixed portion to the multistable portion. The vibration source is configured to produce a resonant vibration to engage the movement of the multistable portion from the first position to the second position.
