  • Pyrophoric arrows
    Patent number: 8635957
    Abstract: An arrow-type warhead (100,200,300,400,500,600,700) comprises an envelope (102,202), a filling (108), a hardened head section (104) to promote penetration of the target and a stabilizing mechanism (106,210,302,402,502,602) to stabilize the warhead in flight, hi some embodiments the filling (108) is pyrophoric and undergoes an exothermic reaction with the envelope upon impact. In other embodiments the filling is incendiary and undergoes reaction with the envelope upon impact in an oxygen rich-environment. In yet other embodiments, the filling is explosive. In all embodiments, the warhead may be equipped with a mini-rocket propulsion mechanism (802) for propelling the warhead to the target.
