Cortland turbine

Post by stevenm »

Bought this a while ago because I think it's a cool idea, but My thoughts here are as follows:
Regarding the turbine drag system....
You would need more room and fluid in front of and behind the turbine for this to work. With the small front/rear turbine area, my thoughts are that it quickly cavitates and makes no diff past a certain point?

None of the fishing reel Engineering experts out there have any thoughts on this? It's a drag, that has a turbine submerged in oil.......
Perhaps back burner it for 50 years and repost :-P

Well the turbine impeller is immersed in a special multi-viscosity oil that supposedly produces no inertial friction at start up and increases drag as the fish runs.

Similar designs have been around for quite a few years, since the '80s. I don't think it was overly popular or well received. It may have been more of a "new innovation" sales gimmick than anything else.
Love those Open Face Spinning Reels! (Especially ABU & ABU/Zebco)

Those were made by STH in Argentina. I have a nice one that was given to a guy named Brock Apfel as a field test. There is some connection between STH and Cortland since you see Cortland sells their cassette spool reels too.

Very cool. Have any pics? Are they identical or subtle diffs?

I've seen a couple variations where the turbine is enclosed in a raised portion of the body. Here's the one I have.

The turbine is dead center on your model, a direct drive vs geared I presume?

Yes, but with a one way clutch disk so there is no drag when taking line out.
