FIELD: machine building.

SUBSTANCE: proposed invention relates to powder pressure accumulators and can be used in aviation, automotive (rescue vehicle) and other industries. Powder pressure accumulator comprises housing with front and rear bottoms accommodating powder cartridges, igniter, primer and pressure transducer mounted on housing front bottom, outlet device with bursting membrane on housing rear bottom. Powder pressure accumulator housing comprises central perforated cup with igniter arranged therein. Powder pellets are tightly arranged between cup and housing. Cup housing surface is shaped with recesses for powder pellets. Perforated cup comprises vertical rows with equal number of holes and number of such rows corresponding to the number of powder pellets. Outlet device has tangential holes of equal diameter placed in two terminal zones of the outlet device with the same number in each of the zones and opposite arrangement. Outlet device is equipped with two flaps with protrusion in each of end zones of at least two diameters of tangential holes relative to their axes. Radial clearance between outlet device and flaps makes 2 to 15 diameters of tangential holes. Distance between the ends of the flaps is not less than 2 diameters of the tangential holes. Flaps are equipped with an external mesh filter with a hermetically installed bursting membrane.
