Aircraft Tire Footprint Forces

Source

The National Tire Modeling Program is a joint National Aeronautics and Space Administration (NASA) - industry effort to improve the understanding of tire mechanics and develop accurate analytical design tools. This effort includes fundamental analytical and experimental research on the structural mechanics of tires. As an integral part of this program, local footprint forces in the normal, lateral, and longitudinal directions were measured with the use of a footprint force transducer. Measurements of forces in the footprint were obtained by positioning the transducer at specified locations within the footprint and externally loading the tire. Data obtained for various inflation pressures and external loads are presented for an aircraft tire. The tire that was tested is representative of those used on the main landing gear of B-737 and DC-9 commercial transport airplanes.
