System activation swiveling nozzle for propellant reaction using multiple sets distributed circumferentially elastic.

A steerable nozzle for propellant reaction, comprising a fixed part (1) intended to be fixed to the propeller, a movable part (2) articulated on the fixed part, a control means (3) for controlling the moving portion, and one or several spring assemblies (4) arranged between the fixed part and the movable part, each comprising spring assembly: at least one fixed resilient stud (40), of which a first end is integral with the fixed part and a second end, opposite the first end, is secured to the rigid part (42), and at least one moving resilient stud (41), of which a first end is integral with the movable part and a second end, opposite the first end, it is integral with said rigid part, characterized in that: said at least one fixed resilient stud and said at least one moving resilient stud are offset relative to each other in a circumferential direction (400) of the nozzle.
