Abstract
The force feedback device includes a stationary housing intended to be secured to an understructure of an aircraft, at least one spring opposing movement of a side-stick of the aircraft relative to the housing, and a transmission mechanism, which is supported by the housing movably and which is suitable for transmitting a rotational movement, around a first rotation axis, between the side-stick and said at least one spring, by applying a force law according to which a resistive force, opposed by said at least one spring, via the transmission mechanism, against the rotational movement of the side-stick around the first rotation axis, depends on an angular position of the side-stick around the first rotation axis. In order for this force feedback device to be more precise, compact and reliable, the transmission mechanism comprises a cam, which is suitable for being connected to the side-stick in rotation around the first rotation axis and which is provided with at least one profiled surface that is shaped so as to define at least one part of the force law, said at least one part of the force law including at least one force jump that corresponds to a discontinuity in intensity of the resistive force without changing the direction of the latter.
