This SAE Aerospace Information Report (AIR) describes the current process for performing comparative wear testing on aircraft tires in a laboratory environment. This technique is applicable to both radial and bias tires, and is pertinent for all aircraft tire sizes.<\/div>\n
This AIR describes a technique based upon \u201cwear\u201d energy. In this technique, side wear energy and drag wear energy are computed as the tire is run through a prescribed test program. The specifics that drive the test setup conditions are discussed in Sections 4<\/span> through 7<\/span>. In general, the technique follows this process:<\/div>\n
    \n
  • \n
    A test profile is developed from measured mechanical property data of the tires under study.<\/div>\n<\/li>\n
  • \n
    Each tire is repeatedly run to the test profile until it is worn to the maximum wear limit (MWL). Several tires, typically 5 to 10, of each tire design are tested.<\/div>\n<\/li>\n
  • \n
    Wear energy is computed for each test cycle and then summed to determine total absorbed wear energy.<\/div>\n<\/li>\n
  • \n
    An index is calculated for each tire design. This is accomplished by dividing the total linear inches of wear at the most worn point into the total wear energy.<\/div>\n<\/li>\n
  • \n
    The indexes are then normalized to provide a comparative wear rate.<\/div>\n<\/li>\n<\/ul>\n
    The described technique is not meant to provide an absolute wear rate or wear index because the technique does not produce results that allow the user to say a tire will last for a specific number of landings. However, it does provide a comparative index. It will make a distinction from one tire design to another by indicating a percentage difference in abrasive wear rate under representative operational conditions. The technique has been demonstrated in a number of test programs and is shown to have an extremely high correlation to field data. Supporting data is included in Section 9<\/span>.<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
