B63H3/00 - CPC Classification

Classification description:

Propeller-blade pitch changing

Sub-classes:

B63H2003/004 » {comprising means for locking blades in position} 5
B63H2003/006 » {Detecting or transmitting propeller-blade pitch angle} 10
B63H3/002 » {with individually adjustable blades} 12
B63H3/008 » {characterised by self-adjusting pitch, e.g. by means of springs, centrifugal forces, hydrodynamic forces} 29
B63H3/02 » actuated by control element coaxial with propeller shaft, e.g. the control element being rotary 11
B63H3/06 » characterised by use of non-mechanical actuating means, e.g. electrical 14
B63H3/10 » characterised by having pitch control conjoint with propulsion plant control 28
B63H3/12 » the pitch being adjustable only when propeller is stationary 1
