ABSTRACT
Aluminum aircraft wheels experience harsh and demanding operating conditions during service, including heat, carbon dust, runway and aircraft fluids, and high-energy braking events. Wheel alloy property design drivers include strength at ambient and elevated temperature, corrosion resistance, density, fatigue behavior, and fracture resistance. The combination of these material properties present in conventional wheel alloys such as 2014 and 7050 naturally drives the structural design of the wheel. A new wrought aluminum alloy, 2040, possesses an enhanced combination of these properties relative to 2014 and 7050 which results in reduced weight wheel designs. Alloy 2040 is targeted for its first commercial aircraft use in the near future. This presentation will review and compare the material property drivers of 2040 with both 2014 and 7050, including wheel roll-on-rim performance.
SPEAKER BIO
Dr. Steele is the Lead Materials Engineer at Goodrich Aircraft Wheels & Brakes located in Troy Ohio. She is responsible for the application development of new materials and or processes for aircraft wheels and brakes. In addition, she manages the fatigue, coatings, and electron microscopy labs. She received her Ph.D. in Materials Engineering from the University of Dayton in 1995 and B.S. in Material Science and Engineering from Wright State University. For the past 10 years she has been working on wheel alloy development focusing on bringing aboard aluminum alloy 2040 as a replacement for 2014, which has been the work-horse aircraft wheel alloy since the 70's.
