Title:R-64 Tire Properties for Radial Aircraft Tires
Issuing Committee:A-5 Aerospace Landing Gear Systems Committee
Scope: Develop a database which will be used to generate a set of predictive equations for a wide range of tire properties for modern (radial) aircraft tires. Methods and parameters to follow the tradition of NASA TR-R64, modified as appropriate/necessary. The application of the resulting paper will facilitate the estimation of radial tire mechanical properties for use in landing gear system models, thereby enhancing aircraft safety.
