Abstract
A composite propellant composition and process are disclosed for reducing e reactive violence during cook-off and to improve the performance of a potassium perchlorate/ammonium perchlorate propellant composition wherein 0.25-2.0% by weight, of iron oxide replaces 0.25-2.0% by weight, of potassium perchlorate in the composition.
Claims10
An improved composite propellant composition containing 30-55%, by weight, of an oxidizer;
- 15-40%, by weight, of a thermal trigger;
- 0.25-2.0% by weight, of a desensitizing agent, and the remainder of the composition comprising a quantity of one or more of, a binder;
- a curing agent;
- a fuel;
- a plasticizer;
- a bonding agent;
- a stabilizer;
- an anti-ozonant;
- and, a cure catalyst.
A process of reducing the reaction violence of a composite propellant composition during cook-off comprising the steps of decreasing the weight percent of the oxidizer or polymer in the composition and adding an equal weight percent of a desensitizing agent.
A method of reducing the cook-off reaction violence, while simultaneously improving the performance, of a composite propellant containing 30-55% by weight, of potassium perchlorate;
- 15-40%, by weight, of an ammonium perchlorate thermal trigger;
- and a quantity of one or more of, a binder;
- a curing agent;
- a fuel;
- a plasticizer;
- a bonding agent;
- a stabilizer;
- an anti-ozonant;
- and a cure catalyst;
- comprising the steps of reducing the weight percentage of the potassium perchlorate by 0.25-2.0% by weight, and replacing it with 0.25.varies.2.0%, by weight, of a desensitizing agent.
