One could believe that the innovative staff at NASA’s Glenn Research Center is watching a little too much “Game of Thrones” based on its new tire that more closely resembles a knight’s meshy armor than that of a tire.
The latest tire — the Superelastic Tire — represents an evolution of the U.S. space agency’s spring tire that was originally invented back in 2009 through a collaboration between NASA and Goodyear inspired by the Apollo mission’s lunar tires.
The new Superelastic Tire was developed with future Mars missions in mind, but NASA says in a news release that it could serve as a potential alternative to pneumatic tires in use here on Earth.
“The novel use of shape memory alloys capable of undergoing high strain as load bearing components, instead of typical elastic materials, results in a tire that can withstand excessive deformation without permanent damage,” NASA writes in a release. “Using shape memory alloy as radial stiffening elements can also increase the load carrying capacity of the tire.
“The Superelastic Tire offers traction equal or superior to conventional pneumatic tires and eliminates the possibility of puncture failures, thereby improving automobile safety. This tire design also eliminates the need for an inner frame which both simplifies and lightens the tire/wheel assembly.”
