Abstract (en)
[origin: FR2791773A1] A vane (1) has a plate (15) of aerofoil section and a leading edge (16). Orifices (I1,I2) on either side of the plate lead to separate air chambers whose pressures are delivered to a processor (9) by a pneumatic joint (8) mounted on the vane axis and shaft (2,3). The processor compares the pressures and sends a signal (C) to a motor (6) on the same shaft such that it rotates the vane until the two chamber pressures are the same.
