Invention and Early Development[edit]

Some early history is reported in Giri L. Agrawal, "Foil Air/Gas Bearing Technology -- An Overview," American Society for Mechanical Engineers, Publication 97-GT-347 (1997) and Giri L. Agrawal, "Foil Bearings Cleared to Land," Mechanical Engineering 120 (July 1998): 1978-80.Mack2 05:19, 26 June 2006 (UTC)[reply]

Another early source: M. A. Barnett and A. Silver, "Application of Air Bearings to High-Speed Turbomachinery," Society of Automotive Engineers International, Technical Paper No. 700720 (September 1970), available at http://www.sae.org/servlets/productDetail?PROD_TYP=PAPER&PROD_CD=700720 . This article has a picture of one of AiResearch's foil bearings and discusses the advances owing to this development.Mack2 08:24, 2 July 2006 (UTC)[reply]

Merger?[edit]

Regarding the suggestion of a merger of varied articles on bearings, bear in mind that the terms referred to in that suggestion (air bearings, hydraulic bearings, dynamic air bearings) are not synonymous. Foil bearings are a very distinct type of air bearing (and share the feature that air is the main lubricant) but in terms of design and function are well defined by the current article on foil bearings, IMO.Mack2 16:21, 29 June 2006 (UTC)[reply]

agree, i've removed the merge note. --Duk 16:58, 29 June 2006 (UTC)[reply]

So why has the suggestion reappeared? I thought this was settled. The tag should be removed. It makes sense to have a "Category" called bearings, of which foil bearings are one type. But they are very distinct from other bearings, even from other hydraulic bearings. Why submerge this distinct invention? It wasn't "air bearings" but rather specifically "foil bearings" that were widely adoped in environmental control systems and certain other high speed and sometimes relatively inaccessible (from a service standpoint) turbomachinery. --Mack2 17:04, 6 August 2006 (UTC)[reply]

Literature[edit]

Added citation to a recent paper presented to Society of Automotive Engineers (SAE) by Klaass and Dellacorte, which provides overview of development and uses foil/fluid bearings from the inception to today. May extract some more "facts" from this to put into the article when I get time.--Mack2 20:39, 19 August 2007 (UTC)[reply]

Compliance?[edit]

In the second sentence of this article, the word "compliant" is used. This is somewhat ambiguous as "compliant" generally refers to an external object. For example, "she is compliant": she complies with other people. "The engine is compliant with 2007 department of transportation mandates": engine complies with mandates from the DoT.

Is the word supposed to be "pliant" or "pliable"? If not, could someone please make explicit reference to that thing to which the lining complies. Idprism 18:06, 11 October 2007 (UTC)[reply]

Mechanical things can be said to be compliant. For example a 'compliant bush'. It means it adapts to circumstances, very typically by flexure. It's a technical use of the word.WolfKeeper 21:17, 11 October 2007 (UTC)[reply]

Agreed, this term is used in the industry.--Mack2 21:24, 13 October 2007 (UTC)[reply]

See, for example: http://www.miti.cc/foil-bearings.html --Mack2 14:37, 16 October 2007 (UTC)[reply]

Advertising[edit]

I'm still adamant that the companies name shouldn't be included on the image's caption. I can't read the company name from the etching on the bearing, even on the full screen version. The name does nothing more than advertise for the company; it adds no encyclopedic value and last I checked we are here to create a an encyclopedic not a manufacturers' directory. Wizard191 (talk) 12:37, 20 July 2010 (UTC)[reply]

As User:Wizard191: doesn't carry forward the encyclopaedic content in any way. --Old Moonraker (talk) 13:11, 20 July 2010 (UTC)[reply]

I completely agree in regards to advertising. Especially from the particular company in question (Mohawk industries). They seem to be working really really hard to get their name and their founder's name Hooshang Heshmat out on wikipedia. This effort seems to be primarily done by relatives to the man in question, and seems like questionable practice. Gregzore (talk) 13:55, 30 July 2010 (UTC)[reply]
