Abstract
A linear fire extinguisher includes a high strength elongated tube containing a pressurized fire extinguishant such as HALON 1301. A pair of opposed shaped charges is placed along the exterior or interior of the tube and when actuated provides cutting lines which cause a directed distribution of the fire extinguishant along the lines in an opposed manner to provide a net reaction force of substantially zero on the tube. A helical geometry is also provided which provides a substantial reduction in reactive forces.
