SYSTEM FOR ACTIVATING A STEERABLE THRUST-VECTORING NOZZLE FOR A JET PROPULSION SYSTEM USING SEVERAL CIRCUMFERENTIALLY DISTRIBUTED ELASTIC ASSEMBLIES

摘要

The invention concerns a thrust-vectoring nozzle for a jet propulsion system comprising a fixed part (1) designed to be fixed to the booster motor, a mobile part (2) articulated on the fixed part, control means (3) for operating the mobile part, and one or several elastic assemblies (4) arranged between the fixed part and the mobile part. Said nozzle is characterised in that each elastic assembly comprises at least a fixed elast ic block (40} whereof one first end is integral with the fixed part and a second end opposite the first one, is integral with a rigid part (42), and at least a mobile elastic block (41), whereof one first end is integral with the mobile pan and a second end opposite the first end is integral with said rigid part (42}. Each mobile elastic block (41) is further offset relatively to each fixed elastic block (40) in a circumferential direction of the nozzle.
