HYDROFOILS FOR SHIPS AND LIKE VESSELS

摘要

A control-surface device for use as a rudder or stabilizer fin. The devices described are of hydrofoil shape with jet discharge slots to either side of the device adjacent its distal portion. When used as a jet flap rudder, a jet of fluid is discharged from the advanced face of the rudder to assist steering. When used to provide a pair of stabilizer fins, jets of fluid are discharged from the leading faces of the fins as these are moved through the supporting fluid by a rolling motion of the ship.
