Title: Innovations by Thomas A. Dwenger in Aircraft Tire Technology
Introduction
Thomas A. Dwenger is a notable inventor based in Uniontown, OH (US), recognized for his contributions to aircraft tire technology. He holds a total of 4 patents, showcasing his innovative approach to enhancing the performance and safety of aircraft tires.
Latest Patents
Dwenger's latest patents include a groundbreaking design for a pneumatic aircraft tire. This tire features carcass plies and/or breaker plies reinforced by high modulus reinforcement cords embedded in a rubber composition that contains no free amines. The rubber composition has a 300% modulus of 12-18 MPa and a minimum tensile strength of 23 MPa, as tested per ASTM D412. Additionally, the tire has a T90 of between 30 and 40 minutes at a reference temperature of 135 degrees C, as tested per ASTM D2084. The cords in the carcass plies and/or breaker plies exhibit a tenacity of 6.6 to 8.2 g/denier, an initial modulus of 120 to 280 g/denier, an elongation at break of 8 to 18%, and a shrinkage of not greater than 3%, with polyester reinforcement cords being preferred.
Another significant patent by Dwenger is for an aircraft tire with a reinforcement insert. This design includes at least one circumferentially extending reinforcement insert located on one side of the tire. Each insert comprises two cord reinforced members with bias angled cords, which are equal but opposite in orientation relative to the cords of the adjacent member. The pairs of reinforced members extend from the bead portion and terminate in a radially upper portion of the sidewall. In a preferred embodiment, the inserts are located on only one side of the tire, although they can also be symmetrically added to each side.
