HIGH-SPEED VESSEL Russian patent published in 2001 - IPC

FIELD: shipbuilding; designing high-speed vessels suitable for transient mode of motion (at displacement-Frounde number between 1.0 and 3.0). SUBSTANCE: vessel has hull with deadrise bottom and extensible active lift force control members. Vessel is provided with load-bearing appendages having blunt trailing edge whose thickness decreases from stern to bow. Lower surface of each load-bearing part is located in one plane with adjacent surface of bottom forming deadrise angle of up to 15 deg. Active lift force control members are located immediately after trailing edge of appendages. Length of load-bearing parts may range from 0.1 to 0.5 of hull length. Ratio of vessel breadth with appendages to hull breadth ranges from 1.2 to 1.2. Vessel may be provided with hydrofoils with controllable flaps. It is good practice to mount one to three pairs of hydrofoils; each hydrofoil may be provided with one to three flaps. Hydrofoils shall be secured to hull directly or by means of one or several struts. Vessel may be provided with water-jet propulsor. It is good practice to provided water scoop of propulsor in bottom before active members. EFFECT: improved service characteristics of high-speed vessel. 6 cl, 3 dwg
