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.

Fluidic logical pyrotechnic initiator

A programmable fluid logic module is disclosed which provides an interface etween a plurality of fluid input signals in a pressure-to-electric transducer. The module is arranged so that a plurality of valves may be used to provide a particular combination of signals which result in the transmission of a desired signal from the module to a pressure-to-electric transducer.
