1. An aircraft propulsion assembly, comprising:
a fixed structure,
a movable thrust reversing structure, and
a linear actuator connected to the movable structure so as to be able to translationally move the movable structure relative to the fixed structure along a longitudinal axis,
the fixed structure comprising an outer casing extending about the longitudinal axis, a hub, a structural arm connecting the outer casing to the hub, a connecting structure connecting the actuator to the outer casing, and fastening devices for fastening the connecting structure to the outer casing,
the movable structure comprising deflection cascades,
wherein the fastening devices are positioned axially between a leading edge and a trailing edge of a head of the structural arm,
wherein the connecting structure comprises a support element integral with the outer casing and a fitting fastened to the support element,
wherein the fitting includes first and second fitting arms extending circumferentially on either side of the actuator, and a rear lug extending circumferentially and connecting rear ends of the first and second fitting arms, and
wherein front ends of the first and second fitting arms are hinged to a gimbal on which the actuator is mounted.
