Abstract : A smoke marker for indicating the location of a target drone is described. An aluminum tube with one open end and one closed end contains a polyethylene bottle filled with titanium tetrachloride, a smoke chemical. The bottle is held in place within the tube by means of set screws adjacent the bottle's neck. A nylon washer containing an explosive primer and a metallic disc are disposed between the bottle and the closed end of the tube. The open end of the tube is potted closed with styrofoam potting. Upon ignition, the explosive primer forces the copper disc to collapse the bottom of the bottle. The neck of the bottle shears and the titanium tetrachloride is expelled from the aluminum tube and the bottle, creating a 25 to 30 foot cloud of smoke.
