The Shape Memory Alloy (SMA) Spring Tire is a non-pneumatic compliant tire developed by NASA Glenn Research Center, along with Goodyear Tire & Rubber Company, to meet the needs of planetary rover missions on the Moon and Mars. This technology consists of SMA springs, which exhibit the “pseudoelastic” phenomena and can withstand approximately 30 times more reversible strain than steel springs. In 2014, the SMA Spring Tire was adapted for Martian rover applications with a focus on durability. Extensive work was performed to mature the SMA Spring Tire to a Technology Readiness Level (TRL) of 6 for the Martian environment. This paper summarizes the developmental work completed to date and presents key characterization data on two SMA Spring Tire point-designs.
