Abstract

A material for generating hot nitrogen gas comprising sodium azide and sulfur in the presence of a conventional solid propellant ignitor.

Claims

2. The composition of claim 1 wherein said azide is sodium azide.

3. The composition of claim 1 which additionally contains a substance or mixture of substances which can produce CO2.

4. The composition of claim 3 wherein said substance is a carbonate.

5. The composition of claim 1 wherein said azide and said sulfur are present in about stoichiometric quantities.

6. The composition of claim 3 wherein said azide and said sulfur are present in about stoichiometric quantities.

7. The composition of claim 1 wherein the quantity of either said azide or said sulfur is not less than about 20 percent of the stoichiometric quantity.

8. The composition of claim 3 wherein the quantity of either said azide or said sulfur is not less than about 20 percent of the stoichiometric quantity.

9. The composition of claim 1 wherein the quantity of said azide or said sulfur is not less than about 75 percent of the stoichiometric quantity.

10. The composition of claim 3 wherein the quantity of either side sulfur or said azide is not less than about 75 percent of the stoichiometric quantity.
