Shape Memory Alloy Tubular Structure

Innovators at NASA’s Glenn Research Center have developed a next-generation, non-pneumatic, compliant tire structure based on shape memory alloy (SMA) elements. This new structure builds upon previous work related to airless tires that were designed for rovers used in planetary exploration. The use of SMAs capable of undergoing high strain as load bearing components results in a tubular structure that can withstand excessive deformation without permanent damage. These structures are capable of performing similarly to traditional pneumatic tires but with no risk of puncture or loss of tire pressure.
