Disclosed is a deploying device that can be installed on a watercraft, particularly a submarine, is used for veering a tubular underwater trailing antenna (10), and comprises a storage drum (11) which receives the trailing antenna (10) and is driven by a motor so as to wind and unwind the trailing antenna (10), and a propulsion unit which grips the trailing antenna (10) and generates a tractive force (F<SB>A</SB>) on the trailing antenna (10) in the direction of deployment. In order to veer said trailing antenna (10) in a disturbance-free and unrestrained manner while keeping the mechanical wear thereof to a minimum, the trailing antenna (10) is directed via a motor-driven guide wheel (14) while a regulating device (20) is provided for synchronizing the driving motors (111, 141) of the storage drum (11) and the guide wheel (14) in a manner that is adapted to the tractive force (F<SB>A</SB>) acting on the trailing antenna (10) such that the section of the trailing antenna, which is located between the storage drum (11) and the guide wheel (14), is essentially stretched.

L'invention concerne un dispositif de largage installé sur un bateau, notamment un sous-marin, pour larguer une antenne remorquée (10) sous-marine de type boyau. Ce dispositif comprend un tambour d'enroulement (11), recevant l'antenne remorquée (10) et entraîné par un moteur pour enrouler et dérouler ladite antenne remorquée (10), et une unité de traction, en prise avec l'antenne remorquée (10) et générant une force de traction (F<SB>A</SB>) agissant sur l'antenne remorquée (10) dans le sens du largage. L'invention vise à réaliser un largage sans gêne ni perturbation de l'antenne remorquée (10), avec un minimum de sollicitations mécaniques exercées sur ladite antenne remorquée (10). A cet effet, l'antenne remorquée (10) est guidée par une roue d'entraînement (14) motorisée et un dispositif de réglage (20) synchronise les moteurs d'entraînement (111, 141) du tambour d'enroulement (11) et de la roue d'entraînement (14) en fonction de la force de traction (F<SB>A</SB>) agissant sur l'antenne remorquée (10), de manière telle que la partie d'antenne remorquée se trouvant entre le tambour d'enroulement (11) et la roue d'entraînement (14) est sensiblement tendue.
