FIELD: rocket manufacture. SUBSTANCE: engine has powder charge 7, igniter 6, nozzle unit 2 in whose bell mouth graphite inter is fitted and diaphragm 5 mounted in supercritical zone. Graphite insert 5 is located in steel thin-walled cylindrical holder. Diaphragm is made in form of unit consisting of thin-walled aluminium disk with circular bore and ring equidistant relative to it. On side of disk, ring is provided with concentric projections; rings is flared out by peripheral portion of disk over outer diameter. On side of nozzle insert, disk has circular groove of triangular section. EFFECT: enhanced operational reliability of engine due to avoidance of break of graphite insert at stable pressures of burst of nozzle diaphragms. 2 dwg
