Abstract
An ignition system for energetics including artillery charges includes a radio frequency transmitter and a radio frequency igniter. The radio frequency igniter receives and converts radio frequency energy into heat or electrical energy for the purpose of igniting energetics, such as propellants or pyrotechnics. The radio frequency igniter may be applied to the exterior of the energetic container or may be integral to the container.
Claims6
A charge ignition system comprising:
- a radio frequency emitter producing a burst of electromagnetic energy into a resonant cavity;
- an energetic charge assembly located within the resonant cavity and further comprising
- a case formed from a consumable material and defining an interior cavity;
- one or more propellant charges located within the interior cavity of the case;
- and
- one or more radio frequency igniters located within the case on a surface of the interior cavity, each of the one or more radio frequency igniters further comprising a radio frequency absorption material for converting the burst of electromagnetic energy into a stimulus for igniting an initiating charge and the initiating charge for initiating one or more of the propellant charges.
