Abstract

A compact, light weight gas generator employing the reaction of a solid grain mixture initiated by a primer. Gases evolved are cooled and filtered through a series of filter disks.

Claims

1. A COMPACT, LIGHT WEIGHT GAS GENERATOR COMPRISING:

A CONTAINER, A COMPOSITION WITHIN SAID CONTAINER CAPABLE OF PRODUCING A GAS IN THE PRESENCE OF HEAT, MEANS ADJACENT ONE END OF SAID CONTAINER FOR FILTERING AND COOLING THE GAS PRODUCED, EXIT MEANS ADJACENT SAID FILTERING AND COOLING MEANS FOR EXHAUSTING THE GAS FROM SAID CONTAINER, AND MEANS FOR PRODUCING AND MAINTAINING THE HEAT FOR SAID GAS-PRODUCING COMPOSITION, INCLUDING;

2. The gas generator of claim 1 wherein said composition comprises a plurality of disks of solid grains of said composition, each disk having a central perforation forming a bore in said composition.

3. The gas generator of claim 2 further comprising:

centrally-perforated disks of heat producing material between said disks of gas-producing composition; and

a perforated cylinder within the bore of said composition to contain said fuze and said quantity of heat producing material.

4. The gas generator of claim 3 wherein said filter means includes:

a plurality of filter discs which permit the flow of gas to cool the gas and preclude the flow of entrained debris; and

a plurality of mesh screens interleaved with said filter discs

5. The gas generator of claim 4 further comprising a membrane sealing said exit means unTil sufficient pressure of the gas produced ruptures the membrane.

6. The gas generator of claim 5 wherein said flammable material comprises heat paper.

7. The gas generator of claim 6 wherein said composition produces hydrogen gas in an exothermic reaction.

8. The gas generator of claim 7 wherein said composition is composed of an ammonium salt and a complex hydride.

9. The gas generator of claim 8 wherein said salt is ammonium chloride and said hydride is lithium aluminum hydride.
