Abstract
A gas generator comprises a propellant container having an igniter at one end thereof for igniting a propellant, a secondary propellant charge comprising a plurality of circular grains having a diameter to thickness ratio greater than 2.5, and a primary propellant charge disposed between said igniter and said secondary propellant charge comprising a plurality of circular grains having a diameter to thickness ratio less than 2.
Claims3
In a gas generator comprising a propellant tube having a plurality of apertures therein, an igniter at one end thereof for igniting a propellant, and a secondary propellant charge in the propellant tube comprising a plurality of right circular cylindrical propellant grains having a diameter to thickness ratio greater than 2, the improvement comprising;
- a primary propellant charge disposed in the first 25 to 75 mm of the propellant tube between said igniter and said secondary propellant charge comprising a plurality of right circular cylindrical propellant grains having a diameter to thickness ratio less than 2 to minimize propellant grain crushing in said primary charge by a shock wave from said igniter.
