FRONT SECTION BODY OF SUPERSONIC REACTIVE PACKET Russian patent published in 2019 - IPC F42B12/32 F42B12/58 

FIELD: rocket equipment.

SUBSTANCE: invention relates to rocket technology and can be used in the development of front sections bodies of supersonic packets and rockets. According to the invention, the thickness of the ogival nose of the outer shell is made variable with increase as it approaches front section thereof. Maximum thickness of the shell is 1.5…3.0 times the thickness of the cylindrical part of the outer shell. Unit of preformed fragments is located on the inner surface of the cylindrical part of the shell and is made in the form of an inner shell with an annular shoulder in front section thereof. It is equipped with preformed fragments. These fragments are interconnected by an elastic non-metallic bonding material with a melting point exceeding at least 1.5 times the maximum temperature of the inner surface of the outer shell in flight. Size of the gap between the inner surface of the outer shell and the inner shell of the preformed fragments unit in 1.10…1.30 times the size of the preformed fragments in the direction radial from the body axis. Preformed fragments are made in the form of metal solid cylindrical bodies with a length of 0.9…1.5 of their diameter. Diameter of the damaging elements of 1.3…3.0 times the thickness of the cylindrical part of the outer shell.

EFFECT: technical result is an increase in the combat effectiveness of the packet due to an increase in the fragmentation and high-explosive destruction effect, ensuring the specified aeroballistic characteristics of the preformed fragments in the target area, increase the reliability of operation by reducing the impact of aerodynamic heating on structural elements.
