Hello,
This is my very first post on this Web site !
I wonder why a mechanism similar to a collective pitch control found in helicopter swash plates
https://en.wikipedia.org/wiki/Swashplate_(aeronautics)#Collective_blade_control
(and in automotive and other clutch (dis)engagement mechanisms as well) is not used in constant speed propellers (at least, I was unable to google anything like that). From the common sense point of view, such a mechanism would be simpler, cheaper and more reliable than a typical hydraulic pitch control mechanism found in piston engines. Plus, it could be used on any engine (even those not provisioned for hydraulic constant speed propellers),and could be driven by a hydraulic cylinder, an electric motor or even purely mechanically (by a cable or a control rod). It could be used together with any kind of an RPM control unit - a mechanical or electronic one. I am just curious.
Thanks in advance!
