Abstract
Ce moteur contrarotatif à stator tournant notamment pour un engin sous-marin, est caractérisé en ce que le stator (2) est associé à un cylindre périphérique (6) en regard de l'enveloppe (7) du moteur et dont la face externe tournée vers cette enveloppe, comporte au moins une rainure hélicoïdale (8) de mise en circulation d'un fluide de refroidissement du moteur entre au moins une entrée (9) et au moins une sortie (10) de fluide ménagées dans l'enveloppe (7) du moteur (1).This contra-rotating motor with a stator rotating, in particular for an underwater vehicle, is characterized in that the stator (2) is associated with a peripheral cylinder (6) facing the casing (7) of the engine and whose external face is turned. towards this envelope, comprises at least one helical groove (8) for circulating an engine cooling fluid between at least one inlet (9) and at least one outlet (10) of fluid formed in the enclosure (7 ) of the engine (1).
