ROCKET LAUNCH BLOCK Russian patent published in 2023 - IPC F42B10/66 

FIELD: rocket technology.

SUBSTANCE: invention relates namely to a rocket launch block. The rocket launch block contains an annular housing, a starting engine with an igniter, including a solid fuel charge with a central channel, a jet nozzle and an enclosing tubular asymmetrical nozzle, a thrust vector deflection device, a mounting unit for the rocket, and a correction system. In the front part of the solid fuel charge with a central channel perpendicular to its longitudinal axis, there are 2 or 3 groups of radial channels identical in geometric parameters and equal in number in each group, each of which is located in a plane passing through their longitudinal axes, with a total area S₁ of the lateral surfaces of the radial channels of all groups, equal to (0.4…1.0) area S₂ of the lateral surface of the central channel. The distance ₃ between the axes of the radial channels of two adjacent groups is within (0.5…1.0) diameter d₂ of the central solid fuel charge channel. The number of radial channels in each group is selected within the range of 4…8. The igniter is mounted in front of the starting engine, where S₁ = πd₁L₁n - the total area of the lateral surfaces of the radial channels of all groups, d₁ - the diameter of the radial channel, L₁ - the length of the radial channel, n - the total number of radial channels in all groups; S ₁ = (0.4…1.0) S₂, S₂ = πd₂L₂ - area of the lateral surface of the central channel, d₂ - diameter of the central channel, L₂ - length of the central channel, L₃ = (0.5…1.0) d₂ - the distance between the axes of the radial channels of two adjacent groups.

EFFECT: increase in the reliability of the rocket launch by increasing the thrust at the initial moment of time.
