<p>The blade (P) has a radial segment (1) and a swept segment (2) successively provided along a pitch axis (A) from a root (20) towards a free end (21) of the blade. The segments have leading edges (3, 4) and trailing edges (6, 5), respectively. A single spar is extended from the root and made of unidirectional inorganic fibers. The single spar has a radial spar (10) in the radial segment, and is divided into primary and secondary spars (11, 12) where the radial segment becomes the swept segment.</p> |
