Madhatter Posted Thursday at 03:48 PM Report Share Posted Thursday at 03:48 PM Aromatic props were used in th 40's and 50's. Self adjusting with aerodynamic forces at different rpm's. Quote Link to comment Share on other sites More sharing options...

Self adjusting with aerodynamic forces at different rpm's. From what I recall they were essentially a two speed propeller. Growing up there was one hanging on the wall in the garage at home. I think it had some damage to the tips of the blades. I'm not sure what happened to it, but I bet dad still has it somewhere. Quote Link to comment Share on other sites More sharing options...
Madhatter Posted Thursday at 04:27 PM Report Share Posted Thursday at 04:27 PM They are heavy and could not be used on many small engines due to moment of inertia limitations. Quote Link to comment Share on other sites More sharing options...

That is what a constant speed prop does. The prop shown here is used primary for sailboats, so when under sail (engine not running), there is less drag by going into the "feather" position.
