This study discussed the preliminary design of marine propeller
through defining its geometries. Basic propeller geometries are being described
initially with parameters such as rake angle, skew angle and pitch to diameter
ratio. Changes of geometries were implemented on chords profile for the Wageningen-B
or Troost series of marine propeller. The CAD tool was successfully utilized
to develop the marine propellers profiles for a whole range of possible parameters
in the Troost series propeller.
