METHOD OF AUTOMATIC FLIGHT CONTROL OF HIGHLY-MANEUVERABLE AIRCRAFT Russian patent published in 2009 - IPC B64C13/18 

FIELD: transportation.

SUBSTANCE: in order to ensure aircraft speed stability, in addition to control signal component formed in computer of static automation of longitudinal control on basis of signals of stick pickoff, normal g-load and angular pitching velocity and provided to first input of aerial rudder, signal is formed corresponding to arithmetic mean value of aircraft balancing calculated for limit values of aircraft center-of-gravity position and weight and provided to second drive input. Signal corresponding to aircraft unbalancing caused by change in aircraft center-of-gravity position and weight during flight is formed and supplied to third drive input, signal of desired balancing movement of control stick is formed. Signal of aircraft unbalancing is formed on the basis of signal of normal g-load and signal of difference between signals of stick pickoff and desired balancing movement of control stick taking into consideration mode of control or stabilisation performed by pilot. Signal corresponding to aircraft unbalancing caused by change in aircraft center-of-gravity position and weight is reset at TAKE-OFF mode and the last value upon engagement of LANDING mode is memorised.

EFFECT: speed stability.
