The design window “is closing” on the final configuration of the re-engined Boeing 737 Max narrowbody airliner.
In the past several weeks, Boeing has announced a series of design updates to the 737 Max, including most recently a new “dual feather” winglet concept aimed at further improving the fuel efficiency of the new airliner. The manufacturer has said it expects to finalize the aircraft’s design by the middle of next year. In a May 2 briefing, Michael Teal, 737 Max chief project engineer, said Boeing has finished aerodynamic trade studies of the aircraft, and the new winglet accounts for the final major design update. “As we are closing in on finalizing the configuration of the airplane to ensure that we meet our commitment on schedule, the window is closing fast, so this is pretty much it,” Teal said of the winglet. “As we firm up to final configuration, we’ll continue to optimize these concepts to maximize the performance benefits.”
