FIELD: transport.SUBSTANCE: invention relates to ship building, particularly, to experimental determination of unsteady forces originating at ship propulsion elements. Proposed device comprises annular adapter, screw propeller, shaft, drive shafting, propulsion complex, recording hardware and dynamometer. Said adapter is secured at ship stern. Screw propeller is fitted in adapter in shaft. Said shaft runs in bearings and is coupled with drive shafting. Drive shafting is located closer to stern compared with propulsion complex. Dynamometer is connected with recording hardware. Dynamometer main elements represent accelerometers. The latter are arranged at propulsion complex fixed parts. Besides, proposed device is furnished with bellow. The latter is arranged between screw propeller shaft, drive shafting and damping assembly. The latter is arranged between propulsion complex and ship model hull.EFFECT: higher accuracy of determination, particularly, in high-frequency band.1 dwg |
