Existing designs? PropCad Premium may be what you need!

Increase productivity with PropCad…

As a user, you will be able to rapidly construct propeller CAD models and 2D drawings. For your designs, you will be able to:

  • Fully define 2D geometry for a completely custom propeller.
  • Use PropCad’s design library to build a “standard” propeller .
  • Build design variants with your own distributions or templates.
  • Rebuild a propeller scan using the PropCad ScanConverter.
  • Import data from data files, including IDF or PFF.

Ensure strength and quality…

You can analyze the strength and materials of your designs using the Classification Society rules. PropCad can automate thickness calculations for fixed pitch, controllable pitch, and nozzle propellers – as well as highly skewed and ice-class propellers! Supported classification societies include:

  • ABS – American Bearuea of Shipping
  • BV – Bureau Veritas
  • RINA – Registro Italiano Navale
  • LR – Llyod’s Register (UK)
  • KR – Korean Register
  • CCS – Chinese Classification Society
  • NK – Nippon Kaiji Kyokai (Japan)
  • Baltic – Sweedish/Finish Rules

Additionally, Ice class designations are available for ABS Steel (A0,B0,C0,D0), BV/RINA (1D), and LR Ship rules (1D/1E), LR Naval rules (1AA, 1A, 1B, 1C) and Swedish/Finnish rules (1AA, 1A, 1B, 1C).

Utilize existing library designs for any geometry…

You can specify your propeller parameters and select the distributions from common library propellers to generate a complete set of propeller geometry data. The design library includes:

  • AU (MAU)
  • B-Series
  • BB-Series
  • Gawn and SK
  • Kaplan types A and C
  • Cleaver and Wedge
  • Symmetric thruster

Communicate designs quickly and clearly…

Once your design is complete, you can automatically prepare and format 2D CAD drawings. PropCad allows users to easily format their CAD views, dimensions, title block, and reported parameters. Drawings can be saved as Adobe PDF, Microsoft Word RTF, or AutoCAD DXF. Additionally, you can supplement 2D CAD drawings with offset reports for 2D and 3D sections.

Transfer data for manufacture…

A propeller design from PropCad is suitable for further development, such as creating FEA, CFD, or CAD/CAM models. Once your design is finalized, PropCad supports data transfer to the most popular CAD packages. Supported packages include:

  • Rhinoceros
  • Solidworks
  • Creo and Pro/Engineer
  • Unigraphics NX
  • SurfCAM
  • MasterCAM
  • DELCAM and PowerShape
  • and more!
