Abstract

The invention relates to a force application device for a control stick of an aircraft, said stick comprising a control lever that is connected to a motor comprising a drive shaft, said device having: a first pin connected to the drive shaft, a housing, a second pin secured to the housing, an electromagnet secured in relation to the housing, a movable actuator which comprises a magnetic material such that said actuator can be displaced depending on a supply of current of the electromagnet, and means for clamping the first pin and the second pin which comprise a first tooth and a second tooth, said device having an operating configuration in which the electromagnet is active and the actuator separates the teeth away from the first pin and the second pin, and a blocking configuration in which the electromagnet is inactive, with the first tooth and the second tooth coming into contact with the first pin and the second pin.

Dependent claims

A force application device for a control stick of an aircraft, wherein the control stick comprises a control lever connected to at least one motor comprising a drive shaft, the drive shaft being rotationally movable about an axis, the force application device comprising:

a first pin, configured to be connected to the drive shaft,
a casing, configured to be fixed with respect to the aircraft,
a second pin, attached to the casing,
an electromagnet, fixed with respect to the casing,
an actuator that is movable with respect to the casing, said actuator comprising a magnetic material, such that said actuator is displaceable as a function of a supply of current to the electromagnet,
means for clamping the first pin and the second pin, comprising a first tooth and a second tooth, the first tooth and the second tooth being movable with respect to the first pin and the second pin,
the force application device having an operational configuration wherein the electromagnet is active and the actuator is positioned between the first tooth and the second tooth such that the first tooth and the second tooth are separated at a distance from the first pin and the second pin, and a locking configuration wherein the electromagnet is inactive and the actuator is retracted such that the first tooth and the second tooth are in contact with the first pin and the second pin.
