METHOD OF ONBOARD CONTROL IN ROCKET FLIGHT EMERGENT TERMINATION Russian patent published in 2013 - IPC B64G1/00 

FIELD: transport.

SUBSTANCE: invention relates to space engineering, particularly, to space rockets. Proposed method consists in intermittent computation by onboard automatic control system of three components of earth velocity vectors (V_XHCCK, Y_YHCCR, V_ZHCCK) and three coordinates of space rocket (X_HCCK Y_HCCK, Z_HCCK) PKH in initial start system of coordinates, membership of every state vector components in lengthwise motion (V_XHCCK, Y_HCCK, X_HCCK, Y_HCCK) sets allowable for given time motion for top and bottom boundaries, and membership for state vector components in lateral motion (V_ZHCCK, Z_HCCK) for sets allowable for given time moment for left right boundaries of sets. In case conditions of membership of controlled parameters are violated in four components of lengthwise motion (V_XHCCK, V_YHCCK, X_HCCK, Y_HCCK) or in two components (V_ZHCCK, Z_HCCK) of lateral motion, geographical coordinates of instantaneous rocker drop onto earth are computed to switch off rocket engine given calculated drop point coordinates are located in one of safe zones.

EFFECT: higher flight reliability of space rocket.
