Mr.AircraftEngineer on Instagram: "This is the definitive visual representation of aeroelasticity enabled by Carbon Fiber Reinforced Polymer (CFRP) construction. The Boeing 787’s wing structure isn't just flexing; it’s actively redistributing load. Unlike traditional aluminum spars (7000-series alloys) which have a lower fatigue limit and stiffness-to-weight ratio, the composite matrix allows for a significantly higher Aspect Ratio (AR) and extreme flexibility without plastic deformation.
