Scope[edit]

Turbine blades exist in turbines other than jet engines, yet this article seems to limit the term. Would it not be more accurate to refer to a fluid rather than a gas, and accommodate further expansion to encompass all turbine blades? Or if the article is limited to its current subject, perhaps the title should be changed to reflect that narrower scope. Kablammo (talk) 05:00, 23 June 2010 (UTC)[reply]

Honestly, the inspiration of the article came from my unhappiness with the quality of the Turbine article and the desire to have a decent article to link to in jet engine articles. Personally, I'm a gas turbine guy so that's the lens that I tend to look through. As you point out, there are many other types of turbine blade (steam, wind, etc.) and this article could feasibly include them. I'm not sure how different steam and gas turbine blades are, but they might be grouped together. I think wind turbine blades are probably sufficiently different that they could be discussed in another article.

Ultimately, however, I don't know how much more expansion I'm going to do here (particularly outside the scope of gas turbine blades. So there needs to be an editor willing to expand the article. I think we can leave the article at its current name until it is either expanded or a second article (e.g., Turbine blade (wind turbine)) is written. Thoughts? -SidewinderX (talk) 11:46, 23 June 2010 (UTC)[reply]

Your article is excellent. There seem to be some common characteristics between gas turbines and other types (and I agree that wind turbines could be handled separately). Ideally the new material would be contributed by someone with knowledge and interest comparable to yours. But that may be unlikely, at least in the short term, and the present piece could suffer if we simply appended onto it a more elementary mention of blades in turbines driven by other fluids.

My interest here arises out of a project to write on the importance of TS King Edward in the development of the marine steam turbine. That development had a few hitches due to problems with turbine blades. Of course, to link that term to this article would be a little misleading.

My own preference is to change the title to reflect the article's focus, rather than add on material which would not be written with the same degree of expertise. It is not however a strong preference; a change in the lede to make the focus more general, and addition of a properly-reference section on other types (even if not as comprehensive as the treatment of gas turbines) would work. But we are all volunteers, and I do not propose to state what you or any other editor should do (especially where I do not have the facility with the material to do it myself).

Well, as a matter of fact, the name for the article was briefly discussed as I was starting the article over at the Aero-Engine Task Force. The thought there (not enough discussion to really call it "consensus") was to just call it Turbine blade and that other stuff could be added later or split out as needed. I agree that there could feasibly be several articles (steam, gas, and wind) written here, or that this article could be expanded to cover those. This article could easily and reasonably be moved to Turbine blade (gas turbine), although that would leave Turbine blade as a redirect (to somewhere) at best, which seems a little silly to me if we have at least one decent article on the topic.

I do you think you make a good point that the lead could be rewritten in more general terms. I'm not sure if I have the time to really do it right now (I'm in the middle of a drawn out process to get CFM International CFM56 through FAC), but if you want to take a crack at it, go for it! And if you want to play around with no risk, feel free to use the sandbox I made for the article here- User:SidewinderX/Sandbox/Turbine_blade

Finally, in terms of your article, there might be some useful information here- Steam_turbine#Principle_of_Operation_and_Design

In reference to user Kabblamo's initial statement, a gas is a fluid. The definition of a fluid is a substance that has the properties to flow easily, has no fixed shape and reacts easily to an outside force. Therefore a gas is a fluid as is a liquid. The properties of a gas are the same in a turbine as for a liquid except a liquid is incompressible. There are two types of turbine setups that are/have been used in gas turbine engines and these are Impulse and Impulse/Reaction. I believe that liquid turbine systems only use Reaction since they are incompressible; compression and diffusion is found in the turbine section of a gas turbine engine.

[edit]

I question whether this is a Turbine blade. Looks more like a compressor blade to me.Petebutt (talk) 15:15, 1 August 2012 (UTC)[reply]

I thought the same thing, but to verify that it IS a turbine blade. http://www.dvidshub.net/image/830936/burner-rig-showing-specimens-rotating-and-not-rotating-utility-turbine-blade-with-thermal-barrier-coating-j-brown-coating-utility-turbine#.UqBZKcRDtEx image from nasa (C) free, perhaps a clearer and more dramatic image for the site? 173.180.199.140 (talk) 10:51, 5 December 2013 (UTC)[reply]

What are the modifications can be made to turbine blades to increase it's productivity??? Sarathnair333 (talk) 01:37, 29 January 2019 (UTC)[reply]

I think this is a super secret corporate research and development type question, so I don't think you'll get an answer?Smellyshirt5 (talk) 01:45, 30 January 2019 (UTC)[reply]
