Appreciate the Significance of Single-Crystal Turbine Blades 5 engine platforms; 7.2M+ flight hours in operation (as of Jan 2021) 920+ aircraft in service (as of Jan 2021) Pratt & Whitney is committing to invest at least $650 million through 2027 to build an investment-casting plant in Asheville, N.C., described as a 1 million sq.ft. The two spools are counter-rotating, which results in weight savings due to the elimination of a row of stators. The first commercial aviation use of the new single crystal airfoils began in 1980 in the JT9D-7R4 jet engine powering the Boeing 747, McDonnell-Douglas DC-10 and Airbus A300 aircraft. One-dimensional crystals. EAST HARTFORD, Conn., February 21, 2018: The American Society of Mechanical Engineers (ASME) has designated Pratt & Whitney’s Single Crystal Turbine Blade as a historic mechanical engineering landmark, recognized for its progression in mechanical engineering and aviation. The engine has turbine blades made of a special single-crystal alloy, making them more resistant to corrosion and metal fatigue. “Having this technology recognized by ASME is a testament to its impact on the aerospace industry.”. Certified at 40,400 pounds of thrust, Pratt & Whitney’s F117 is the exclusive power for the U.S. Air Force’s advanced transport, the C-17 Globemaster III, developed by The Boeing Company. However, in the early 1960s, researchers at Pratt & Whitney Aircraft (now Pratt & Whitney, P&W, owned by United Technologies Corp) set out to deal with the problem through elimination of grain boundaries from turbine airfoils, by inventing techniques to cast single-crystal (SX) turbine blades and vanes. Through its History and Heritage program, the ASME encourages public understanding of mechanical engineering, fosters the preservation of this heritage and helps engineers become more involved in all aspects of history. Such a single crystal turbine blade for a Pratt and Whitney PW2037 turbofan engine is shown in Fig. Pratt & Whitney engineers have determined that high power and high temperature operations can cause the CT blades to crack or break due to “blade creep”. Might have missed it but why no acknowledgement that directionally solidified and single crystal nickel alloy gas turbine blade technology was invented and developed to bill of material status under the guidance of Frank Versnyder at Pratt & Whitney’s Advanced Materials R & D Laboratory in Connecticut in the 1960s? 36 Perimeter Road Windsor Once again, casting technology advancement spurred alloy development to optimize capability fro m the new technology and was pioneered by Pratt & Whitney.
