METHOD OF SAFE LAUNCHING OF ROCKET WITH MULTIENGINE FIRST STAGE Russian patent published in 2013 - IPC B64G1/26 

FIELD: transport.

SUBSTANCE: invention relates to aerospace engineering and may be used in clustered rocket bodies. In nonexplosive failure of one of the engines, crash rocket is withdrawn by turning it from pad structures through pitch and hunt angles preloaded in control program and by emergency programs through said angles per the number engines and two fields of drop in the area of space center. In flight, control system is used to computer coordinates of instantaneous fault point, to define failure of engine not accelerated to full thrust by integral criterion and characteristic parameters of rocket motion irrespective of engine onboard diagnostics transducer readings. Given the failure, drop field is selected depending upon failure detection time as well as appropriate emergency program of pitch and hunt angles to withdraw rocket from pad structures. Then, failed engine is cut off along with running engines provided coordinates of instantaneous drop point belong in aforesaid selected field of rocket drop. In the case of normal operation of the engines, flight is controlled in compliance with standard program pf pitch and hunt angles.

EFFECT: simplified pad design, higher safety, longer life.
