FIELD: military equipment.

SUBSTANCE: invention relates to jet engines for ammunition intended for firing from anti-sabotage grenade launcher systems, arranged on floating warships, stationary or mobile objects on shore. Jet propellant engine comprises combustion chamber 2 with tubular powder charge 3 of "brush" structure arranged therein, separated from igniter 5 by diaphragm 4, having through holes and nozzle. Separating diaphragm in the chamber is installed movably, and on its external contour there are evenly located holes, which form along the perimeter of the diaphragm projections in the form of teeth 10, wherein the ratio of the total area of the holes to the area of the circle described by the teeth ranges from 0.279 to 0.339, and the ratio of the outer diameter of the diaphragm to the inner diameter of the combustion chamber ranges from 0.997 to 1.028. Separation diaphragm is made from non-metallic material with thickness of at least 1 mm, for example, cardboard.

EFFECT: invention ensures preservation of igniter at transport loads and simplifies diaphragm design.
