Abstract
The patent is about an integrated automatic control system for controlling ship potions (ride control system) mainly at high speeds, using air-fed foils of complex construction as a means for generating the required control forces.The currently avialable ride control systems are based on hydrofoils appropriately mounted on the ship's hull that can be rotted round their lonnngiitudinal axis, varying the andgle of attack and therefore controlling the lift force generated on their surface.Thesesystems, although effective in common navigaaation seeds, are ineffective in high speeds for two reasons : (a) the mechanical system that is used to constantly alter the foil position must be operate in conditionnns of ever increasing frequencies as thw navigation speed increases and the preiod of encounter decreases and therefore is subjected to high cycle-high stress loading, develoring fatiguw problems (b) at high speeds (over 30 knots) the foils operate in severe cavitation conditions resulting in materila wearing and decreased effectiveness in generating lift forces.In order to face these problems the present invention is introduced which is an automatic ride control system based on foils appropriately mounted on a ship's hull, thatare capable of generatinng lift forces on command by controlling the quantity of mixture of air and water vapro injected on their surface (1) through network of small ducts (3) and nozzles (2) positioned on the surface. The foils are constructed using both metallic and composite materialw for high strength, low structural weight and effective and low cost surface treatment for achieving hydrodynamic surfece of high accuracy. The foils consists of the metal supporting structure made of steel, aluminum, titanium etc., the small ducts network and nozzles for the injection of air and water vapro mixture, and the hydrodynamic surface made of composite materials such as fiberglass, resins, Kevlar etc.The automatic intefrated ride control syste
