ABSTRACT:
A fluidic pyrotechnic initiator capable of initiating a fluid resonator cridge initiator upon receipt of a low pressure input signal. A monostable supersonic wall-attachment fluidic amplifier is used with a control channel to detach the supersonic jet, causing it to impact the resonator tube of the initiator. A vent is provided to keep an over pressure in the control channel from initiating the cartridge.
