MULTI-STAGE ROCKET AND HEAD METHOD OF USED PARTS SEPARATION Russian patent published in 2019 - IPC F42B15/12 

FIELD: astronautics.

SUBSTANCE: invention relates to rocket engineering, particularly, to multistage rockets. Multistage rocket comprises body with head fairing, behind which there is an additional fuel compartment arranged along longitudinal axis of rocket with possibility of its separation from rocket, equipped with additional fuel tanks, compartment for payload, fuel tanks connected with rocket engines. Additional fuel compartment is divided into segments with possibility of separation of each segment from rocket, with rotation to design angle relative to rocket axis and with speed excluding damage to rocket. Segments are arranged one above another along the rocket longitudinal axis. In each of the segments there are fuel tanks and a fairing with the device providing the possibility of the fuel pipeline killing and its disconnection. To the rocket engines along the longitudinal and / or transverse axis of the rocket there adjoins at least one accelerating separated stage. It contains fuel tanks and rocket engines with possibility to consume fuel from certain fuel tanks along fuel pipeline by opening and closing corresponding valves.

EFFECT: technical result is higher efficiency of device due to replacement of operating rocket engines during flight with separation of spent fuel tanks without separation of rocket engines.
