ROCKET MISSILE Russian patent published in 2017 - IPC F42B15/00 

FIELD: weapon and ammunition.

SUBSTANCE: rocket part contains a body with a thermal protective coating and a block of stabilisers. Sleeve of elastic material with low ablation temperature in ring groove is arranged in front of block of stabilisers ahead at a distance of 0.025…0.25 of gauge from the butt of body and block of stabilisers at the inner surface of the body. At the butting position between heat insulation and sleeve, said insulation has inner circular ledge abutting on sleeve. The end surface of the sleeve facing the block of stabilisers is made with an internal circular ledge with an internal diameter equal to the inner diameter of sleeve and an outer diameter not exceeding the inner diameter of block of stabiliser. In the threaded connection between the missile body and the block of stabilisers body, a ring of material with low thermal conductivity is installed.

EFFECT: increasing the reliability of rocket part by reducing heating in the area of threaded connection of the body and the block of stabilisers, and damping of the acoustic vibrations.
