Patent ID: 6877435

Claim:
A gas generator comprising at least first and second adjacent gas generation compartments, each being capable of discharging gas therefrom at a different time and different volumetric rate, wherein each compartment contains the same propellant and initiator, further wherein the propellant has a different geometry in each compartment which results in different rates of gas evolution from each compartment upon initiation such that the ratio of gas generation in the first compartment to that in the second compartment is greater than one; and also wherein said propellant consists essentially of on a weight basis approximately (a) 84-95% of phase-stabilized ammonium nitrate as an oxidizer, (b) 3.4-13.4% of a fuel selected from the group consisting of CL-20, RDX, HMX, TATB, LLM-105, EDNA, and mixtures thereof, and (c) 1.5-2.6% of a binder selected from the group consisting of PCL, PIB, and polyvinylpyrrolidone, and mixtures thereof, the products of combustion of said propellant being non-toxic gases.
