Abstract
A bird-wing broadhead blade is a blade that has a free end that is positioned in a back or downstream position from a fixed end. The free end of the bird-wing blade extends out, like a bird opens its wings to fly. A bird-wing broadhead blade may incorporate a shape memory alloy material that has a set shape, such as by thermal setting. A shape memory alloy bird-wing broadhead blade may be deformed into a strained shape and retained until hitting an object. When the shape memory blade is released, it will move into the set shape automatically. A shape memory alloy is a metal alloy that 'remembers' its set shape and has superelastic properties. A spring deployment system may also be used to deploy one or more bird-wing blades. A spring may be configured upstream or downstream of the fixed end of the blades.
