Propellers, e.g. of "ducted type"; features common to propellers and rotors for rotorcraft.[1][2]
The phrase "ducted propeller" means is a propeller whose nozzle does not rotate; another name is Kort nozzle.[3]
This class covers:
- Propeller hubs, blades and pitch-changing mechanisms[2]
- Propeller vibration absorbing or balancing means; Arrangements of multiple propellers (e.g. coaxial propellers).[2]
- Active or passive propeller measures for noise reduction (only such disclosures are attributed the symbol CPC B64C11/00).[2]
