Webb16 nov. 2024 · While standard wingtips can reduce drag by as much as 4.5%, the raked wing design can reduce it by 5.5%. Despite the one percent increase, raked wingtips only work on larger aircraft and are much less economical on smaller planes like the Boeing 737 or Airbus A320. 787 wings are incredibly flexible Webb25 aug. 2024 · This is not necessarily a bad thing, as it dampens gusts and other turbulence. In fact, raked wings actually reduce the total bending moment, and bending fatigue at the root of the wing. This is because the higher sweep reduces the lift curve at the wingtip at high angles of attack. casestudy stuvia https://casadepalomas.com
