SAFETY AND ARMING UNIT

FIELD: military equipment.SUBSTANCE: invention relates to military equipment. Safety and arming unit for the combat part of a guided munition with a marching engine and with an onboard power supply connected to the safety and arming unit after the launch of the ammunition, includes located in the body of an electric detonator, a spring-loaded movable flap with a central hole located in the cocked position of the flap coaxially with the electric detonator, a fuse, an inertial locking mechanism in the form of a spring loaded load, as well as a shunt of the electric detonator interacting with the shutter, the shutter being made of an electrically insulating material with a metal insert pressed into it in the central part, the shunt of the electric detonator is made in the form of a strung string rigidly connected by ends to the terminals of the electric detonator and installed perpendicular to the path of the flap, the inertial locking mechanism is located at the side of the flap, and the flap has a restrictive protrusion, the length of which is longer than the distance from the side of the flap to the cargo in its extended position. Front end of the flap, directed towards the string, can be made oblique at an angle with the formation of a sharp edge. Metal insert can be made of at least one steel disc having a diameter larger than the diameter of the flap opening. Flap can be made predominantly of a thermoplastic. Load of the inertial locking mechanism can have a bonnet, and the restrictive projection of the shutter is made in the form of a shelf located below the load cap in its extended position.EFFECT: invention makes it possible to increase the reliability of the operation of ammunition in the regular mode and ensures an increase in security in official circulation.5 cl, 8 dwg Изобретение относится к военной технике.
