HIGH-SPEED VESSEL Russian patent published in 2001 - IPC

FIELD: shipbuilding; designing high-speed vessels for running in transient and gliding modes. SUBSTANCE: high- speed vessel has hull with bilge-like lines and keel bottom with force and/or aft planing steps. Mounted after planing steps are controllable interceptors which may be extended from under break of bottom for turning relative to supports by means of rods. Supports are secured on bottom of hull in after-planing-step space by means of shoes. One bearing part of each shoe is welded to bottom. Other bearing part is provided with bearing surface which is parallel to edge of respective planing step and is perpendicular to hull CL. Supports of interceptors are secured on above-mentioned bearing surfaces of shoes by means of detachable joints. Interceptor may be electrically insulated from shoes. It is good practice to make working surfaces of interceptors of cylindrical or convex form. EFFECT: facilitated shipbuilding procedure; simplified control of interceptors in mounting; enhanced reliability of ship's hull equipped with complex of controllable interceptors. 3 cl, 4 dwg
