Improvement of Overload Capability of Air Carrier Aircraft Tires.

摘要

Statistical and analytical data are used to develop Transport Aircraft Ground Operations scenarios describing tire loads, deflections, temperatures, and distance traveled. These scenarios are used to aid in defining the critical conditions causing tire overload. Reasons for failure of overloaded tires are developed and used to identify potential improvements for overload capability for tires currently in use. Cost tradeoff studies are made to indicate which of the improvements appear promising for further development. Concepts for new designs capable of overload are discussed along with 'runflat-ideas.' Using information developed in the program, tire maintenance practices that may improve the overload performance of current tires are presented.
