Abstract

Projectile sous-marin, ensemble et procédé de lancement associés La présente invention concerne un projectile (12) comportant : une coque (16) ; un arbre rotatif (26) ; et une hélice (30, 50) apte à être entraînée en rotation par ledit arbre rotatif. L’hélice et la coque comprennent respectivement une butée (56) et une contre-butée (58) en vis-à-vis l’une de l’autre. L’hélice est apte à coulisser axialement entre une première position, dans laquelle un jeu (62) non nul est ménagé entre les butée et contre-butée, et une deuxième position, dans laquelle les butée et contre-butée sont en contact. Un élément de rappel élastique (33) est réversiblement déformable entre un premier et un deuxième états de contrainte, correspondant respectivement à la première et à la deuxième positions de l’hélice, la contrainte du premier état étant inférieure à la contrainte du deuxième état. Figure pour l'abrégé : Figure 2
