Goodyear And NASA Successfully Recreate Original Moon Tire
Akron OH (SPX) Dec 05, 2008 Goodyear Tire and Rubber and NASA have taken one small step backward to make one giant leap forward and help prepare for future missions to the moon and to Mars. Goodyear and the NASA Glenn Research Center (GRC) recently completed a jointly-funded project for the development and production of twelve replicates of the original wire-mesh moon tire used on the Apollo Lunar Roving Vehicle in the early 1970s. This was the first step toward understanding this unique non-pneumatic tire technology, and its applications on both the moon and Earth. "Although there was some reference material for designing the replicate tire, there was little detail about the manufacturing process," said Goodyear Project Leader Rick Laske, noting how the team had to reinvent techniques to recreate the wire mesh tire. The team examined one of the moon tires on display at the National Air and Space Museum in Washington, D.C., and corresponded with two retired members of the Apollo Lunar Roving Vehicle team, who each had a tire that had been given to them as a souvenir for their work. Examination of the original moon tires provided the primary reference information for judging the quality of the replicates, according to Vivake Asnani, NASA's principal investigator. Four major components comprise the tire and wheel design: mesh, tread, inner-frame, and hub. The mesh is woven from piano wire and the tread is a series of metal strips intended to protect the mesh from impact while providing increased contact area for floatation in soft soil. An inner-frame, comprised of a relatively rigid metal structure, prevents the mesh from over- deforming during impact, while the hub holds the mesh and inner-frame together and connects the assembly to the vehicle. |
