AIRCRAFT PITCH ANGLE BANK ANGULAR SPEED LIMITING AUTOMATIC CONTROL SYSTEM Russian patent published in 2011 - IPC B64C13/18 

FIELD: transport.

SUBSTANCE: invention relates to ACS for control over aircraft pitch angle. Pitch angle and angle of attach limitation ACS comprises setter of pitch angle and computer of pitch angle autopilot, servo drive its output signal defining the angle of aircraft elevator deflection, aircraft pitch transducer, setter of maximum angle of attack, computer of angle of attack limitation and algebraic selector of maximum signal, and transducer of aircraft angular speed. Aircraft pitch angle transducer output is connected to second input of pitch angle autopilot computer. Maximum signal selector output is connected to servo drive input. Aircraft bank angle transducer output is connected to third input of bank angle autopilot computer. Bank angle autopilot computer output is connected with second input of algebraic selector of maximum signal.

EFFECT: accurate limitation of angle of attack and smooth transition processes in ACS.
