737 Max wingtips kept under wraps
Boeing is yet to settle on a wingtip configuration for the 737 Max despite having last week firmed up several key design attributes of its revamped narrowbody twinjet family.
Current 737s are offered with Aviation Partners Boeing (APB)-supplied blended winglets, while the US Navy's 737-based P-8 features 777-style raked wingtips. Boeing's 737 Max chief project engineer and deputy programme manager Michael Teal says the manufacturer is "testing a possible revision to the wing tips on the Max" in the wind tunnel to "see if this new technology could further benefit the airplane".
Boeing says it will continue with aerodynamic, engine and airframe trade studies to optimise the design of the 737 Max by mid-2013.
