Abstract : Aircraft tires were constructed using radial steel plies constrained with circumferentially wound breakers and utilizing silicone as the elastomer. The tires were capable of performing at 200 mph after undergoing soaks at 350 F. Dynamic tests were conducted after soaks up to 450 F. Static hydroburst testing was conducted up to 513 F. The current limiting factor in the tire design is adhesion of the silicone to the wire cables of the breaker. Liner extrusion, sidewall cracking, and bead chafing which had been deficiencies of the silicone-steel tire in the past were resolved. Although the primary elastomers studied were the high temperature Siloxane polymers, a cursory investigation of other polymers with attractive high temperature characteristics was conducted. A high temperature characteristics was conducted. A high temperature test wheel suitable for brake testing was supplied to ASD. (Author)
