METHOD ROCKET LAUNCHING Russian patent published in 2012 - IPC B64G1/24 B64G1/52 

FIELD: transport.

SUBSTANCE: invention relates to operation of rockets with the first stage multi-engine pack. Said pack may consist of central engine and two lateral engines arranged in common plane, e.g. in rocket yaw plane. In case one of said lateral engines fails in launching, less the explosion, remaining engines or their part are switched over into thrust augmentation. Rocket is stabilised in vertical position to preset lift altitude. Then, rocket is turned down bank unless engine location plane is aligned with that of rocket safe zone plane. Note here that faulty engine is directed toward ram airflow. Angular parameters of rocket deviation in direction of launch path end are kept within tolerances to allow rocket further stabilisation. To ensure shock-less release of chambers from launch table recesses, lateral engines are mounted with equal angular inclination from rocket lengthwise axis. Chambers are registered in zero position relative to said axis while registration is cancelled at rocket motion start. Note that lateral axes of lateral chambers are aligned, after their release from recesses, with those of lateral engines.

EFFECT: higher safety.
