EditBy FREE!ship Plus is further development of the program with free source code FREE!ship v2.6 under license GNU GPL. FREE!ship Plus it intended for the full parametric Analysis of resistance and power prediction for a ship and other calculations of hydrodynamics of vessels and underwater vehicles. FREE!ship Plus allows the designer to simulate and analyze condition of Balance of a complex completely hull - rudders - keels - engine - propellers in different regimes and of service conditions of a ship. The analyzable system includes a hull, appendages, a propeller and the engine (i.e. resistance, power, a thrust and a torque moment), and also various service conditions (heaving, a wind, a shallow-water effect, a regime of tow / pushing, etc.). Calculations in FREE!ship Plus are based on the systematic serial tests of models of the ships and boats, inclusive more then 31 published methods and series for calculation of resistance of a hull and 17 screw Diagrams of 5 types of propellers and waterjet. As is known, one of the most basic errors at calculations of resistance and power prediction under serial diagrams, is that the designer uses not that serial diagram, or Combination of the incompatible data and formulas. In order to prevent it, the program analyses input data and, if they true or insignificantly leave from allowable ranges, uses extrapolation for calculations with the indication of parameters, published allowable ranges. New Features: * Added calculation power and resistance of small ships by van Oortmerssen's * Added nonsymmetrical layers * Added half Entrance angle by Holtrop-84 formulae calculation in van * Added influence shaft of propeller data for planing ships in Savitsky method calcs * Added calculation power and resistance of semiplaning ships by Mercier-Savitsky method * method (1971) * Oortmerssen's method * Added into Mercier-Savitsky method graphics output 15 points * Added leak points under DWL model test in hydrostatics calcs
