Patent ID: 8607702

Claim:
A low energy ignition primer device for a large caliber ammunition projectile canister which canister further includes a propellant bed and a projectile, said device comprising: a metallic primer head assembly which is electrically grounded; an electrically insulating Torlon® cup pressed into an indented area of said primer head assembly; a firing pin located in a cavity in said Torlon® cup to which firing pin an electrical pulse may be applied; a first chamber in said primer head assembly comprising non-electrically conductive ignition composition made up of aluminum based nano material combined with oxidizer and binder, and; a metallic coated non energetic element also in said first chamber, said non energetic element electrically connected to said firing pin, and said non energetic element also electrically grounded to said primer head assembly through aid of slip-in connection clips further located in said firing pin cavity, and; wherein application of an electrical pulse to said firing pin causes activation of said non energetic element to generate ionized plasma which plasma in turn will ignite said non-electrically conductive ignition composition in said first chamber, and; said device also including a venting orifice disc and pin retainer which can vent composition from said first chamber into a closing plug, said closing plug having a closing plug chamber with aluminum based nano material combined with oxidizer and binder, said closing plug chamber also leading to a vent, and said vent further leading to a venting tube chamber of said projectile canister, said venting tube chamber further containing said propellant bed, and; whereby ignition of such propellant bed leads to launch of said projectile from said canister.
