FIELD: rocket equipment.
SUBSTANCE: invention relates to rocket engineering and can be used in sub-caliber small-sized rocket projectiles fired from launch tubes with a device for centering and guiding. Detachable sub-caliber missile master device consists of several sectors that are spring-loaded in the radial direction relative to the longitudinal axis of the projectile. Radial protrusions and counter grooves with equidistant protrusions surfaces are made on the lateral surfaces of the sectors in contact with each other. Front ends of the sectors are made flat and provided with protrusions in contact with the inner surface of the launch tube, the height of which is not less than half the difference between the internal diameter of the tube and the caliber of the projectile.
EFFECT: invention allows to increase the reliability of the device operation while increasing the safety of its use and reducing its resistance when moving and exiting the launch tube.
