... Recent research in the possible applications of the vortex propulsor – Vor-Prop - have included open cylinder model, a shafted coaming contained compact model and a double counter rotational internal turbine model. CFD analysis indicates efficiencies in applications including ship propulsion...

... Since 1869 the main goal of whirling vibration calculations of rotating machinery was to determine critical speeds. Currently, all Classification Societies require a propulsion shafting whirling vibration calculation (also named bending or lateral vibration calculation) in the scope...

... obtained on the base of widely used approaches implemented by the authors in propulsion shaft calculation software. Practical recommendations for setting of propeller hydrodynamic loads in the case of lack of data for full calculation are proposed. The procedure for the propeller load validation...

... Results are presented from captive model tests on the effect of waterjet propulsion flows on the static maneuvering coefficients for sway force and yaw moment for a model of a large waterjet-propelled sealift ship configuration. Towing basin tests were conducted for the measurement of hull surge...

...Note: Scanned pages 15-23 from the printed version has been added at the end due to some formatting issues and missing pictures in the original PDF. Experience with carbon fiber tubes in ship propulsion Dipl.-Ing. Gerhard Kirschey ABSTRACT Carbon Fiber Tubes have been used as propulsion shafts...

... There are three main problems for engineers specializing in propulsion train calculation. The first problem is a lack of a single shaft model to perform all types of shaft related calculations, the second is the inability to analyze different operation states of propulsion shafting in one click...

...Detecting and Correcting Propulsion Shafting Misalignment Andrew A. Donaghy1, (M) The intent of this paper is to place in the hands of owners and ship repairers, phrased in simple terms, a guide to recognize problems caused by propulsion shafting misalignment and provide well tested methods...
