摘要
A composite material blade is provided having a twin longeron and twin box structure with laminated honeycomb sandwich coverings, including a front leading edge longeron of a C shaped section, a central longeron with two sole pieces at the ends of a transverse web with honeycomb filling sandwiched between lateral sheets, and laminated coverings made from honeycomb panels sandwiched between external and internal sheets formed by stacking layers of fiber fabric, so as to define two boxes filled with very light foam cores, the sole pieces being integrated in the coverings which are joined at the level of the trailing edge by a rider in the form of a foam wedge.
