Talk:Kaplan turbine
From Wikipedia, the free encyclopedia
[edit] Images
A characteristic and necessary feature of a Kaplan turbine is a pivoting hub to allow the blade angles to be tilted. The Bonneville powerhouse is said to have Kaplan turbines, but the picture now here is not a Kaplan as far as I can tell - no blade pivot! I removed the reference to my picture of a propeller blade runner and corrected the description on the Commons, though I found a lot of errors on the other pictures there. There is one actual (small) Kaplan turbine runner picture on the Commons but most of what's there are fixed pitch propeller runners or impossible to distinguish. --Wtshymanski 15:14, 10 August 2007 (UTC)
- I think it's a Kaplan turbine, just covered with a lot of scale and rust - and the nose cone has been removed. Look at the root connection between the blades and the hub. --Duk 15:50, 10 August 2007 (UTC)
- Yes, the structure at the bottom could be part of the servo for the blade angle - but it's a very rusty turbine indeed. (It may have been standing for months before they pulled it? I wonder why they took the head cover out with the runner?) I wish the picture showed the blade pivots more clearly but even blowing up the image didn't convince me. I'll leave it in till we get a better one and I'll put the best one off Commons in the article, too. --Wtshymanski 17:45, 10 August 2007 (UTC)
- Yeh - I bet we can find a better one. --Duk 19:08, 10 August 2007 (UTC)
