Abstract
A system and method is provided for igniting a propellant with an electrically conductive chemically insensitive polymer. The polymer is an electrical resistance heater to heat the propellant to its ignition temperature. Preferably, the polymer is an organic polymer. Surfaces of the propellant can be coated with the polymer. In the alternative, the polymer can be applied to a hollow bore in the propellant to form a self-pressurizing charge. Advantageously, the present invention controls ignition and prevents unintended ignition of the propellant.
