Abstract: The present invention is a self-propelled arrow, consisting of an otherwise conventional hunting or target practice arrow that is propelled by CO2 and water, thus providing additional thrust to the arrow when shot from a bow. String inertia causes a CO2 filled cartridge to strike the point of a puncture means which punctures the cartridge and releases charged CO2 into a water storage chamber which charges the water inside. The charged water becomes pressurized and actuates a pliable closure membrane to an open position in check valve fashion, thus releasing the pressurized water from the water storage chamber through the propellant jets in the rear of the arrow. This system accelerates the arrow and decreases the arrow drop, thereby increasing the range and speed of the arrow immensely. The CO2 cartridges may be replaceable.

Abstract: A hunting arrow having an elastomeric device attached to the inside of the hollow shaft of the hunting arrow is used for the tracking of game animals that have been struck with the hunting arrow.

Abstract: A hollow shaft hunting arrow carries a small volume of liquified carbon dioxide which is released by flash expansion upon penetration into the thorax of a game animal. The thorax is pressurized with carbon dioxide gas at sub-zero temperature to cause collapse of the lungs and fibrillation of the heart, so that the animal can be harvested on the spot, thus avoiding escape and uncertain recovery. The liquified carbon dioxide is carried in an internal reservoir and is released by flash expansion upon opening actuation of a valve closure member. The arrowhead includes a freely movable center core which is attached to an actuator shaft that is engagable with a release valve. The release valve is actuated by either piercing a metallic membrane, fracturing a glass or ceramic lens or unseating the ball closure of a ball valve assembly.
