Decoy rounds and their method of fabrication

A method for producing a line type charge adapted for dispersing energy generating material in an effective pattern for confusing energy sensing devices comprising the steps of:

• mixing potassium perchlorate of particle size capable of passing through a screen of about a number twenty size with black aluminum in the ratio of about five parts by weight of the screened perchlorate to about two parts by weight of the aluminum;
• passing the mixture a predetermined number of times through a separating means capable of passing material up to about the size which can be passed through about a number twenty screen;
• containing the mixture;
• and positioning a fusing member therein.

A method for assembling decoy rounds adapted for confusing energy sensing devices comprising the steps of:

• positioning a plug-like means in one end of an internal cavity extending through a load of energy generating material;
• securing the plug-like member with the cavity;
• wrapping at least one layer of suitable material around the load with sufficient material extending beyond the load to cover the ends thereof;
• securing the material;
• locating a burst charge within the load cavity and in abutment with the plug-like member;
• covering the ends of the load with suitable members;
• folding the extending material over the members;
• positioning additional members over the folded material;
• lacing the thus assembled unit with suitable material;
• applying at least one layer of suitable material around the laced unit and securing the same thereto;
• positioning ignitor means along side the thus assembled unit;
• wrapping suitable material around a portion of the unit and ignitor means which contains the plug-like member with the material extending past the end thereof;
• supplying a lift charge to within the area defined by the extending material;
• closing the extending material so as to contain the lift charge;
• operatively connecting a time fuse means with the ignitor means and the burst charge;
• covering the other portion of the unit and ignitor means and the time fuse means with suitable material;
• securing the covering material close to the end of load;
• operatively connecting a firing means with the ignitor means within an open end of the covering material;
• and securing the covering material over the firing means;
• wherein the burst charge is properly contained with respect to the load of energy generating material for effectively dispersing the load, and is isolated from the lift charge, while each of the ignitor means, fusing means and firing means is protected and thereby assured of proper operation.
