초록

System for control of an aerodynamic surface (1) of an aircraft, comprising an intentional actuation member (5) and a hydraulic jack (2) intended to deflect said aerodynamic surface (1). According to the invention, the system comprises means (14) for detecting the difference in pressures prevailing in said jack (2), on either side of the piston (2C) of the latter, and calculation means (11) comprising: a computer delivering values of a coefficient which is a decreasing function of said difference in pressures; and a multiplier receiving an electrical sig...
