Dynamisk stabiliseringsinnretning for et undervannsfartøy

摘要

The method involves mounting a wing (7-c) and/or a control surface freely rotating around an axle transversal to a roll axis (5a) of a submarine engine. Archimedes thrust torque on the wing is utilized such that volume of the wing or the control surface respectively, is arranged behind or front of a rotation axis. A ballast (90) is mounted on the roll axis, and a hydrodynamic force is generated to bring the wing and or the control surface towards a reference angular position of the engine corresponding to a reduced roll. Independent claims are also included for the following: (1) a sub marine engine comprising a body (2) a utilization of a wing or a control surface on a submarine engine.
