摘要: A stabilising vane for arrows is described, which comprises:
a base shaped to be connected at a tail of a shaft of an arrow, wherein the base extends along a first direction between a first and a second end; where the first direction coincides with the flight direction of the vane when the arrow is in flight;
a body connected to the base and extending away from the base substantially along a second direction starting from a first point positioned at a marginal position of a first side positioned at the first end and from a second point positioned at a marginal position of a second side positioned at the second end of the base; wherein the body further extends between a third side and a fourth side of the base; the first point and the second point facing the fourth side, the body has an airfoil having a convex upper surface and a concave lower surface; the body has a variable thickness.-
