Abstract

Una tobera (14) para sistemas de propulsión que comprende: un bastidor (32) que comprende una pluralidad de elementos deflectores (40) dispuestos en una matriz (42), extendiéndose dicha matriz alrededor de un eje longitudinal (L); un conjunto de accionamiento (36) conectado de forma operativa a dicho bastidor para suministrar una fuerza de deflexión a dicho bastidor, en la que dicho conjunto de accionamiento comprende un anillo desplazable (64) y una pluralidad de conectores (66), en el que cada conector de dicha pluralidad de conectores se extiende desde dicho anillo desplazable a un elemento deflector asociado de dicha pluralidad de elementos deflectores, y en el que cada elemento deflector de dicha pluralidad de elementos deflectores produce un desplazamiento lateral en respuesta a una fuerza de deflexión aplicada en una dirección sustancialmente paralela a dicho eje longitudinal; y un revestimiento (34) colocado sobre dicho bastidor; caracterizada por que dicho conjunto de accionamiento comprende además un anillo estacionario (62), en la que dicho anillo desplazable es desplazable con respecto a dicho anillo estacionario.
