Pulsed fluid jet apparatus and munition system incorporating same

摘要

A fluid jet apparatus (101) includes a housing (103,105) defining a propellant cavity (207), a fluid cavity (213), and a passage (107) through the housing in fluid communication with the fluid cavity (213). The apparatus further includes a membrane (221) separating the propellant cavity (207) and the fluid cavity (213), a propellant (209) disposed in the propellant cavity (207), and a fluid (215) retained in the fluid cavity (213). The propellant (209) urges the fluid (215) from the fluid cavity (213) through the passage (107) upon initiation of the propellant (209). A munition system includes a munition and at least one fluid jet apparatus (101) adapted to vent the munition. A method includes initiating a propellant (209) to produce a rapidly expanding gas and urging a fluid (213) through a passageway (107) with the gas to produce a fluid jet.
