AUTOMATIC FLIGHT CONTROL METHOD OF HIGH-PERFORMANCE AIRCRAFT Russian patent published in 2010 - IPC B64C13/00 

FIELD: transport.

SUBSTANCE: invention refers to automatic flight control method of high-performance aircraft, which involves static longitudinal control automat with limit attack (overload) angle limiter. For forming the signal of allowable attack angle within its limit values, there additionally formed is limit attack angle signal on the basis of the signal corresponding to actual attack angle value and on the basis of the signal corresponding to the specified limit attack angle value. Amplification coefficient of the signal corresponding to actual attack angle value is decreased by means of functional block from 1 when actual attack angle value reaches the value corresponding to the first specified limit attack angle value to the value close to zero when actual attack angle value reaches the value corresponding to the second specified limit attack angle value. The received signal is restored by means of aperiodic link to limit values and supplied to computer input of longitudinal control automat with limit attack (overload) angle limiter.

EFFECT: decreasing overcontrol in the system for attack (overload) angle almost to zero, which allows sufficiently improving characteristics of longitudinal stability and controllability during aircraft operation at limit attack angles and overloads.
