Directional fin a hydrodynamic lift wireless weather by setting rotating blade leading to a trailing edge flap

摘要

The present invention relates to a directional fin (1) to hydrodynamic lift adjustable, mounted on a pivot (2) fixed to a boat, the control surface or stabilizes. A rotor (4), on the axis of rotation (5) perpendicular to the axis (2) carries a radial or of the profiled blades (6) to the pitch angle which is adjustable, which collect a hydrodynamic torque of the direction and intensity adjustable. This setting is regulated by a primary mechanism driven by an actuator or manually controlled by computer. The rotor drives by a mechanism of the orientation of a secondary flap (3) articulated at the trailing edge of the fin (1), which it causes the orientation. In the case of an obstacle, the blades are retracted. Actuator and mechanisms are housed in socket of the fin or of the flap. The energy consumption is low and the short response time. The removable version, standardizable, is mounted on existing rudders rapidly by adapter.
