B63H5/10 - CPC Classification

Classification description:

Arrangements on vessels of propulsion elements directly acting on water of propellers of more than one propeller of coaxial type, e.g. of counter-rotative type

Sub-classes:

B63H2005/103 » {of co-rotative type, i.e. rotating in the same direction, e.g. twin propellers} 8
B63H2005/106 » {with drive shafts of second or further propellers co-axially passing through hub of first propeller, e.g. counter-rotating tandem propellers with co-axial drive shafts} 21
