CONTROL ACTUATOR OF ALL-MOVING AERODYNAMIC SURFACE Russian patent published in 1997 - IPC

FIELD: deflection of all-moving aerodynamic surfaces (control surfaces, outer panels of tiltable wings, etc). SUBSTANCE: additional control aerodynamic surface is rotatably mounted on trailing edge of all-moving aerodynamic surface which is mechanically linked with output shaft of servo unit mounted in fuselage of flying vehicle. input of first attitude sensor is mechanically connected with axle of all moving aerodynamic surface and its output is electrically connected with first input of summing amplifier; input of second attitude sensor is mechanically linked with axle of additional control aerodynamic surface; output of second attitude sensor is electrically connected with second input of summing amplifier and with of first differentiating amplifier whose output is electrically connected with input of inventor and with input of second attitude sensor. Outputs of inverter and second attitude sensor are electrically connected with third and fourth inputs of summing amplifier respectively to whose fifth input drive input signal is furnished which is proportional to present angle of deflection of additional control aerodynamic surface. Output of summing amplifier is electrically connected with input of control member os servo unit. EFFECT: low cost of manufacture; high response in wide range of loads of servo unit. 1 dwg
