Abstract
Propellant compositions are coated with an energetic deterrent coating which reduces the burning rate at the surface of the propellant grain and causes the propellant to burn progressively. The use of energetic materials, that are slightly soluble in the coating solvent, improve the burning properties of the propellant without decreasing the chemical energy.
Claims17
A gun propellant composition comprising:
- a propellant grain component;
- and,
- an energetic deterrent coating composed of at least one slow burning energetic coated onto the propellant grain component, wherein the at least one slow burning energetic material reduces he burn rate at the surface of the propellant grain and causes the propellant to burn progressively and the energetic deterrent coating comprises a compound selected from the group consisting of TATB, HZTZ, PITNE, PINANE, LLM-105, FOX-7 and combinations thereof.
A method of manufacturing a gun propellant composition having an energetic deterrent coating, comprising the steps of:
- forming a propellant grain component;
- dissolving an energetic deterrent coating into a solvent wherein the energetic deterrent coating comprises a compound selected from the group consisting, of TATB, HZTZ, PITNE, PINANE, LLM-105, FOX-7 and combinations thereof;
- and,
- applying the dissolved energetic deterrent onto the formed propellant grain component.
