    摘要: A rotor blade has a chord and a span length perpendicular to the chord. The rotor blade includes a first skin having an inner surface and a first plurality of elements extending from the inner surface. The first plurality of elements are distributed along at least a portion of the span length and inclined with respect to the chord of the rotor blade. A second skin is attached to the first skin so as to form an outer surface of the rotor blade. The second skin has a second plurality of elements extending towards the inner surface of the first skin and engaging with the first plurality of elements to form a plurality of ribs within the rotor blade.

    摘要: A blade-profile blank for a propeller comprises a first elongate, non-twisted part (1) of streamlined cross-section and of constant cross-sectional area and constant shape from one end of said part to its other, and a second, planar part (2) which connects with one longitudinally extending edge of the first part and which is of constant thickness and breadth. The second part (2) has a surface (5) which merges at least substantially tangentially with one, convex single-curve surface (3) of the first part, and a surface (6) which merges smoothly with the other surface (4) of the first part (1).
