AIRCRAFT FLIGHT AUTOMATIC CONTROL SYSTEM Russian patent published in 2005 - IPC

FIELD: aircraft flight control systems at spatial maneuverability.

SUBSTANCE: proposed system includes control circuit for control of flying speed by means of thrust controller and trajectory angle control circuit which are interconnected by means of trajectory angle correction unit. Correction unit generates trajectory angle correction signal Θ_cor whose magnitude shows that part of energy which shall be transferred from one circuit to other and sign shows the circuit to which energy is transferred. Conditions for switching-on the preset trajectory angle correction signal assume: excess of error modulus |V-V₃|≥δ_ex; operation at engine "idling", "maximal" or "boost" control stick set at stop, i.e. R(t)=R_idle or R(t)=R_boost; agreement of error signal V-V₃ and longitudinal acceleration of flying vehicle sign [(V-V₃)xn_x=1. These conditions are realized by logic unit.

EFFECT: extended functional capabilities; enhanced safety of flight within allowed range of flying speeds.
