Secondly, because they conform to the terrain and do not sink as much as rigid wheels, they can carry heavier payloads for the same given mass and volume. AKRON, OHIO, August 3, 2009 – The National Aeronautics and Space Administration (NASA) and The Goodyear Tire & Rubber Company have developed an airless tire to transport large, long-range vehicles across the surface of the moon.
NASA Glenn engineers rebuilt Apollo era tires and developed new designs using newer materials and technology to better function on a lunar surface. Usually, reinventing the wheel is used as a metaphor for wasting time and resources to create something that already exists. New NASA Tires Never Get Flat and Are Almost Indestructible. NASA’s new contracts will omit astronauts, but set up the first American landing on the moon in nearly 50 years. Materials engineers at NASA have just created an exciting new tire that could help to improve transport over rough, extraterrestrial terrain.
A lunar roving vehicle, left on the moon during the Apollo 15 mission in 1971. First, they would allow rovers to explore greater regions of the surface than currently possible. But in the case of these tires, progress dictates that we re-imagine the possibilities of this simple invention.I understand and agree that registration on or use of this site constitutes agreement to its User Agreement and Privacy Policy When the new alloy is stressed, it can snap back into its original configuration, which is why it is known as a “memory alloy.” This new wheel is not meant for use on Earth but in the future, there could be terrestrial applications with the help of friction causing coatings.Along with potential, future Earth applications for the technology, there may also be new alloys that could give these wheels new properties. It has to do with the atomic structure. And whether youâre on Earth or as far away as the Moon or Mars, you need good tires to get your vehicle from one place to another. The last NASA vehicle to visit the Moon was the Lunar Roving Vehicle. Evolving since the days of Apollo, NASA engineers started examining tire designs back in the 1960's for use on the surface of the Moon.The American Modularized Equipment Transporter (MET): a two-wheeled unpowered cart used smooth rubber tires supported by nitrogen filled inner-tubes and manufactured by Goodyear to make it easier to pull the cart through soft lunar soil and over rocks. NASA Glenn engineers rebuilt Apollo era tires and developed new designs using newer materials and technology to better function on a lunar surface.A little over a year after the Mars Curiosity Rover landed on Mars, engineers began to notice NASA Glenn engineers thought their work on Spring Tires might be a new and better solution for exploration rovers on Mars. From the Moon to Mars. It performed impressively on the punishing track.So, why are shape memory alloys the key to success for this new generation of spring tires? Please refer to the following Exploration requires mobility. This site requires that JavaScript be enabled in your browser. There are three major benefits to developing high performing compliant tires that are capable of performing in a Martian or Lunar environment. Lastly, because the compliant tires can absorb energy from impacts at moderate to high speeds, they can be used on crewed exploration vehicles which are expected to move at speeds significantly higher than the current Mars rovers. NASA Reinvents the Wheel With Magic Chainmail Tires For the Moon, Mars, and Beyond The new material is capable of deforming all the way down … Thin tread strips were attached to the carcass to enhance flotation in soft lunar soil.While NASA was developing rovers to send to Mars, there was also interest in taking a new look at returning to the Moon. While NASA was developing rovers to send to Mars, there was also interest in taking a new look at returning to the Moon.
The result is a new type of metal spring tire made of a nickel-titanium alloy instead of steel.This alloy allows the material to rearrange on an atomic level as opposed to deforming. This manned vehicle used four large flexible wire mesh wheels with stiff inner frames to prevent over-deflection. Jumping off of the original concept that helped the moon buggy zip around on the surface of the Moon, metal wheels with steel springs, the team is applying new advances in materials science. Tire development for space exploration has been a focus of research at NASA Glenn for a decade.
