Abstract

Flow modifying devices are simultaneously operative on the upper and lower surfaces of a fixed stabilizer foil on the submerged pod or hull of an ocean vessel to modify the lift hydrodynamically induced under control of pivotal flaps during propulsion of the vessel. The lift otherwise induced by the pivotal flaps is directionally reversed for all angular positions thereof by the spoiler devices.
