HYDROFOIL SHIP FAULTLESS CAREEN ABATEMENT Russian patent published in 2014 - IPC B63H25/04 

FIELD: transport.

SUBSTANCE: invention relates to ship building, particularly, to careen automatic damping devices. For faultless hydrofoil ship careen abatement measurement the following gadgets are used: flap turn angle transducer unit, careen angle transducer, differentiation angle, flap drive unit, controllers unit, the following signals being fed to inputs of the latter: flap angle deflection and derivative of careen angle evaluation. Besides, this method exploits the ship speed transducer, careen angle transducer, two careen angle evaluation diagnostics units and two careen angle evaluation filters, the following signals being fed to first inputs of the latter: flap deflection angles and ship speed.

EFFECT: higher precision of stabilisation, faultless operation of this system, careen transducer and ship ACS.
