FIELD: transport.
SUBSTANCE: rotorcraft screw blade comprises stiff jointing insert 1 and spar running from blade root to blade free tip. Jointing inset 1 has top, bottom, front, rear left and right side surfaces 2, 3, 4, 5, 6, and 7. Aforesaid spar comprises succession of fiber layers that retain said insert 1 jointed to blade root. Spar is jointed to top, bottom, front, rear and left side surfaces 2, 3, 4, 5, and 7. Proposed method consists in forming blade spar. First support shaft 8 is jointed to stiff jointing insert 1 reversible jointed to holder 20. Fibers are arranged around assembly comprising jointing inserts 1 and holder 20 to make blade spar. First shaft 8 is removed after spar polymerisation.
EFFECT: simplified production.
