METHOD TO CONTROL AIRCRAFT WITH SELF-OSCILLATING DEVICE OF AERODYNAMIC CONTROL SURFACES Russian patent published in 2011 - IPC F42B15/01 

FIELD: weapons and ammunition.

SUBSTANCE: in the method to control an aircraft with a self-oscillating drive of aerodynamic control surfaces with vibration linearisation of the control system, a control signal is generated by a control system of an aircraft using a self-oscillating drive of aerodynamic control surfaces, and the control surfaces are deflected with the drive. Prior to start of the aircraft the aerodynamic load onto control surfaces of the self-oscillating drive is simulated, and the function of drive self-oscillations amplitude sensitivity is determined to the value of the aerodynamic load of control surfaces, as well as the function of the expected displacement of the coordinate of the aerodynamic control surfaces pressure centre relative to the coordinate of position of their rotation axis depending on the time of aircraft flight. Amplitude and frequency of a linearising signal are identified. In process of aircraft control the amplitude of the linearising signal is modified in a program manner with account of the function of drive self-oscillations amplitude sensitivity to the value of the aerodynamic load of control surfaces relative to the function of the expected displacement of the coordinate of aerodynamic control surfaces pressure centre relative to the coordinate of position of their rotation axis.

EFFECT: increased dynamic characteristics of an aircraft and expanded conditions of its application.
