Abstract

A shaped gas-generating charge comprising a solid, substantially oxidizer self-sufficient, gas-generating grain and a combustion-restricting polymeric inhibitor containing a woven reinforcement and a vaporizable material to cool the polymeric inhibitor and to retard the decomposition of the inhibitor polymer to prevent the introduction of inhibitor decomposition products into the generated gas stream. Vaporizable material is present in the inhibitor in a concentration of from about 10 to about 50 percent by weight based on the total weight of the polymer and vaporizable material in the inhibitor.

Claims

2. The article of claim 1 further characterized by said coolant being a particulate solid.

3. The article of claim 2 further characterized by said particulate solid being ammonium phosphate.

4. The article of claim 1 further characterized by said woven inorganic reinforcement being woven asbestos fabric.
