Abstract
A steerable nozzle for a reaction engine comprises a fixed portion (1) for fixing to the engine, a moving portion (2) hinged to the fixed portion, control means (3) for controlling the moving portion, and one or more resilient assemblies (4) disposed between the fixed portion and the moving portion. The nozzle is characterized in that each resilient assembly comprises at least one fixed resilient stud (40) having a first end secured to the fixed portion and a second end, opposite from the first end, secured to a rigid piece (42); and at least one moving resilient stud (41) having a first end secured to the moving portion and a second end, opposite from the first end, secured to said rigid piece (42). In addition, each moving resilient stud (41) is offset relative to each fixed resilient stud (40) in a circumferential direction of the nozzle.
