The present invention is a self-propelled arrow, consisting of an otherwise conventional hunting or target practice arrow that is propelled by CO.sub.2 and water, thus providing additional thrust to the arrow when shot from a bow. String inertia causes a CO.sub.2 filled cartridge to strike the point of a puncture means which punctures the cartridge and releases charged CO.sub.2 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 arrowand decreases the arrow drop, thereby increasing the range and speed of the arrow immensely. The CO.sub.2 cartridges may be replaceable.

[ What is claimed is:] [1.]1. A self-propelled arrow comprising:an otherwise conventional, linearly elongated, cylindrical arrow shaft with an interior volume having a forward end opposite a rear end;an arrow tip terminating said forward end of said arrow shaft;propellant discharge orifice formed at said rear end of said arrow shaft;a water storage chamber for holding water and located inside said interior volume at said forward end;a replaceable cartridge containing a pressurized gas, said replaceable cartridge slidably inserted and positioned inside said interior volume forward said water storage chamber immediately adjacent to said arrow tip;a first spherical, pliable closure membrane located on an upper end of said water storage chamber;a second spherical, pliable closure membrane located on a lower end of said water storage chamber, anda spring safety means affixed along a perimeter of an upper end of the first pliable closure member for preventing said cartridge from striking said water storage chamber except during firing of said arrow, wherein said spring safety means has a pointed, puncture means resting inside said spring safety means directed at said first pliable closure membrane.
