Abstract
A primary ignition system for large caliber ammunition which ignition system is less sensitive to unwanted ignition by conventional temperatures or conventional electrical signals or by stray electrostatic voltage electrical signals, or stray RF frequency signals. This ignition primer device begins the ignition sequence with applying a high voltage electrical pulse to a non-energetic element, specially coated with nano sized aluminum particles, to release and ionized discharge that generate a plasma in order to ignite an environmentally friendly ignition composition mix. The ignition composition is also comprised of aluminum water based nano material combined with oxidizer and binder. In the device's primer head assembly is a brass ignition pin pressed into a (non-electrically conductive) Torlon® material cup. The non-conductive Torlon® material acts as an insulator for the entire system.
