Composite fan blades? I guess that means carbon-carbon. Is that a wise idea after RCC failed so tragically on STS Columbia? 195.70.32.136 10:44, 14 February 2006 (UTC)[reply]
No they are made from carbon fibers in an epoxy matrix. This is a good reference for technical data: [1]
Hello all! The unit of jet thrust is kilonewtons (kN). Wikipedia looks retro with all of its museum units like "lbf", which 97% of the world population has no clue about.
The weirdest thing is anglo-saxon units are just unofficial variants of the SI system. All pound, feet, etc. are actually derived from the Paris SI measurements, because no comparable precision etalons exist in the anglosaxon world. 91.83.16.172 (talk) 12:12, 10 May 2008 (UTC)[reply]
Wikipedia looks retro because that is the unit that is used in industry. I worked at GE on the GEnx project for three years and I never heard anyone say "kilonewton" once. The problem is that you have this huge company that has (literally) millions of legacy drawings and specifications that are in the "old" system of units. Changing them all over to the "new" system would cost a fortune. So they stick with what they've got. I'm sure the marketing brochures that they distribute in Europe say kN, but all of the engineers say lbf. Sorry. Kiracofe8 (talk) 14:47, 19 March 2009 (UTC)[reply]
Dead Link, and more on units
Actually, in my experience, engineers from most parts of the world use metric units or even better the exact SI units, I've never heard an engineer use an imperial unit, but then again I've never spoken to an american or British engineer.

It's used in the industry in the USA. Aerospace/gas turbine manufacturers based in the UK and other countries (Rolls Royce, Airbus etc.), NASA, the USAF, and US Space Force all use metric. Providing it in both systems here is correct though, since both are in use in industry. 90.241.10.18 (talk) 17:44, 9 October 2021 (UTC)[reply]

Links tend to be blacklisted because they have a history of being spammed, or are highly innappropriate for Wikipedia.
This, however, doesn't necessarily mean it's spam, or not a good link.
If the link is a good link, you may wish to request whitelisting by going to the request page for whitelisting.
If you feel the link being caught by the blacklist is a false positive, or no longer needed on the blacklist, you may request the regex be removed or altered at the blacklist request page.
If the link is blacklisted globally and you feel the above applies you may request to whitelist it using the before mentioned request page, or request its removal, or alteration, at the request page on meta.
When requesting whitelisting, be sure to supply the link to be whitelisted and wrap the link in nowiki tags.
The whitelisting process can take its time so once a request has been filled out, you may set the invisible parameter on the tag to true.
Please be aware that the bot will replace removed tags, and will remove misplaced tags regularly.[reply]

Can anyone provide any details on the industrial risk sharing partners for the GEnx? — Preceding unsigned comment added by 143.115.159.58 (talk) 15:32, 2 November 2017 (UTC)[reply]
Hello fellow Wikipedians,
I have just modified one external link on General Electric GEnx. Please take a moment to review my edit. If you have any questions, or need the bot to ignore the links, or the page altogether, please visit this simple FaQ for additional information. I made the following changes:

Look, I get it, there is a sourced comment that correctly says the 787 was originally designed to have interchangable engines, but that hasn't actually been true for 15 years. So why revert the edit to retain this amazingly out-of-date (and now incorrect) information?
Since you didn't like my edit that corrected this to say it was originally true, I'll just delete it entirely. It's not actually relevant to an article about the engine, anyway. — Preceding unsigned comment added by 130.76.24.19 (talk) 00:18, 18 December 2018 (UTC)[reply]
I have used the web archive link as the original page isn't there any more. Please replace if you can find a link to the NTSB notice. Gusfriend (talk) 05:16, 25 January 2022 (UTC)[reply]
