Device for operating a controlled member on a rotary-wing aircraft, particularly a helicopter

An apparatus for operating a controlled member (2) on a rotary-wing aircraft, said apparatus (1) comprising:

• at least one control (3) intended to be subject to the action of a pilot of said rotary-wing aircraft and capable of moving a linkage (4);
• means (5) connected to said linkage (4) for operating said controlled member (2) as a function of movement of said linkage (4);
• a first control device of a first type, said first control device comprising a ram (7) incorporated into the linkage (4) which is capable of influencing the movement of said linkage (4) as a function of control commands received;
• a second control device of a second type different than said first type, said second control device comprising a trim means (13) capable of acting on the control (3) and on the linkage (4) as a function of control commands received;
• a computer (9) determining said control commands which are transmitted to said ram (7) and to said trim means (13);
• and
• at least one sensor (10) which is capable of measuring the values of a parameter that represents an action exerted by a pilot of the rotary-wing aircraft on an auxiliary control (3, 18),
• wherein said computer (9) uses the values measured by said sensor (10) to determine said control commands to create control objectives, and
• wherein said control (3) and said auxiliary control (18) are set out on the rotary-wing aircraft in such a way as to be accessible and operable by one and the same pilot of said aircraft,
• wherein the parameter measured by said sensor (10) is relative movement of said auxiliary control (3, 18) with respect to the position of the trim means (13).

• wherein, for a rotary-wing aircraft flown by two pilots, said control (3) is subject to the action of one of said pilots, and
• wherein said auxiliary control (18) is subject to the action of the other pilot,
• wherein the parameter measured by said sensor (10) is relative movement of said auxiliary control (3, 18) with respect to the position of the trim means (13).
