Blade steering apparatus
View Patent ↗A steering element for a blade which is preferably mounted with respect to or part of an arrowhead or broadhead. During flight, a leading surface of the steering element contacts with airflow. One or more force components act in a direction generally perpendicular to a flat surface of the blade, to impart rotation or spin of a body of the arrowhead about a longitudinal axis of the arrowhead.
1. An arrowhead comprising;
at least two blades attached with respect to a body of the arrowhead, each of said blades having a flat surface on at least one face of one of said blade and an insert mounted within a cutout of said blade, and a steering element extending outward from said flat surface.
2. An arrowhead according to claim 1 , wherein said steering element has a leading surface, and a distance between said leading surface and said flat surface of said blade increases in a direction from a front of said leading surface to a rear of said leading surface.
3. An arrowhead according to claim 2 , wherein said leading surface is flat.
4. An arrowhead according to claim 2 , wherein said leading surface is curved.
5. An arrowhead according to claim 2 , wherein at least a portion of said leading surface is concave.
6. An arrowhead according to claim 1 , wherein said steering element is integrated with said blade.
7. An arrowhead according to claim 1 , wherein said steering element is connected to said blade.
8. An arrowhead according to claim 1 , wherein said flat surface is planar.
9. An arrowhead according to claim 1 , wherein each said blade is removably attached to said body.
10. An arrowhead according to claim 1 wherein each said blade is pivotably mounted with respect to said body.
11. A blade for an arrowhead, the blade comprising:
a flat surface on at least one face of one of said blade and an insert mounted within a cutout of said blade, and a steering element extending outward from said flat surface.
12. A blade according to claim 11 , wherein said steering element has a leading surface, and a distance between said leading surface and said flat surface of said blade increases in a direction from a front of said leading surface to a rear of said leading surface.
13. A blade according to claim 12 , wherein said leading surface is flat.
14. A blade according to claim 12 , wherein said leading surface is curved.
15. A blade according to claim 12 , wherein at least a portion of said leading surface is concave.
16. A blade according to claim 11 , wherein said steering element is integrated with said blade.
17. A blade according to claim 11 , wherein said steering element is connected to said blade.
18. A blade according to claim; 11 , wherein said flat surface is planar.
19. A blade according to claim 11 , wherein a layer of adhesive is positioned between said flat surface and a bottom surface of said steering element.
20. A blade according to claim 11 , wherein said blade is pivotally attached with respect to a body of an arrowhead.
