FIELD: rocket engineering.
SUBSTANCE: intended for use in missiles. The rocket part contains a body, a bottom, a tail block, a nozzle, including inlet and outlet cones with liners, and the inlet cone liner is made with a cone angle equal to (7… 18°), and is equipped with a cylindrical section with a diameter of (0.71… 1.6) Dedge and length (0.11… 0.72) Dcr, and the output cone liner is made, accordingly, with a cone angle equal to (11… 24°), and is equipped with a cylindrical section with a diameter of (0.7… 1.8) Dedge and length (0.3… 1.1) Dcr. In a particular case, the inlet and outlet cones are equipped with liners made of a material with a low thermal conductivity temperature.
EFFECT: improving the reliability of the functioning of a rocket unit using high-energy fuels by maintaining energy characteristics, as well as reducing the degree of entrainment of material from the blades.
