Research and Test Apparatus

A new installation at the Akron, Ohio, U.S.A. plant of the Goodyear Tire and Rubber Co. enables tests to be carried out on tyres for aircraft and high‐performance automobiles. The dynamometer system provides the designer with the opportunity to duplicate the tyre life for all conditions of aircraft operation including: taxiing, take‐off, landing and also cross‐wind effects. The stimulation of surface speeds up to 320 m.p.h. can be effected and hence, because of the physical dangers involved in a tyre failure at this high running speed, actual test runs are viewed on a closed circuit television screen.
