Yacht Research Unit Kiel - Velocity prediction program

Sailing Yacht Velocity and Performance Prediction

Several VPPs and Performance prediction Tools are in daily use at YRU-Kiel

  • AVPP is a classical VPP with a full featured user Interface. It focusses on classical monohulls. The aerodynamic and hydrodynamic models to predict flow Forces can either be based on generic empirical estimates or on wind tunnel-, towing tank- or CFD-results. As such AVPP serves as a´n experimental post processor to asses sailing yacht Performance, for which hydro- and aerodynamic experiments have been carried out by YRU-Kiel
  • XVPP is an Excel-based VPP featuring the same aero- and hydrodynamic models as AVPP. It can easily be employed for variational studies of design alternatives or to assess changes the sail set, to the rig and to the main dimensions. XVPP is Freeware.
  • RVPP is a dynamic top-Level VPP embedded into a RANSE flow solver. It calculates flow Forces from solving the RANS equations and is coupled with a Motion solver to predict the bahavior of the yacht in six degrees of freedom.
  • Research VPPs and Performance prediction Tools: YRU-Kiel has developed some r&d-VPPs dedicated to multihulls, canting keel yachts and other unconventional yachts.
