Abstract
A high performance propellant having greatly reduced hydrogen chloride emission is disclosed comprising a minor amount of hydrocarbon binder (10-15%) and at least 85% solids including ammonium nitrate as the primary oxidizer (about 40% to 70%), a significant amount (5-25%) powdered metal fuel, such as aluminum, a small amount (5-25%) of ammonium perchlorate as a supplementary oxidizer and optionally a small amount (0-20%) of a nitramine such as HMX.

A solid rocket propellant having greatly reduced hydrogen chloride emission comprising:
- about 10-15% of an elastomeric butadiene polymer binder containing over 85% by weight solids;
- the solids including 40% to 70% ammonium nitrate as a primary oxidizer, 5% to 20% powdered metal fuel and 5% to 35% of a secondary oxidizer including 5% to 25% ammonium perchlorate and 10% to 20% of an organic nitramine oxidizer.
