Wikipedia Xenophobia at Work
[edit]So this is how it works? Undo and lock? Even if it would be idiocy to do so? "Welcome to Wikipedia, the free encyclopedia that anyone can edit" my ass. --91.55.228.111 (talk) —Preceding undated comment added 05:09, 18 August 2009 (UTC).
Bypass Ratio?
[edit]I think bypass ratio needs to be added to the template. It is an important specification for turbofan engines. For turbojets/turboshafts/etc, it can just be left blank. -SidewinderX (talk) 14:46, 24 September 2009 (UTC)
- Yes, it was added but forgot to say so! Nimbus (Cumulus nimbus floats by) 15:43, 1 January 2010 (UTC)
Mass flow and pressure ratio
[edit]Is there any chance that someone knowledgable can change the Compression to Pressure ratio and the aircon (meaningless) to Massflow? And add an entry for E.P.R.Petebutt (talk) 05:24, 20 December 2011 (UTC)
- OK, I have incorporated what I have suggested in a test template at User:Petebutt/aero-engine manuf template how do I incorporate the changes in the mainpage template without causing widespread upset?Petebutt (talk) 05:53, 20 December 2011 (UTC)
Turbine inlet temperature
[edit]The template is misleading (IMHO)
It should be understood that the numbers in type certificates record the temperature AFTER the [compressor/gas generator/HP] turbine, at which point it is low enough to be measured by thermocouples.
See, for example, the PWC 306B
where the temperature, described as 'Measured Interturbine Temperature', is given as 920C.
This has been copied into the 'Specifications' of the article
https://wiki.riteme.site/wiki/Pratt_%26_Whitney_Canada_PW300
However, 920C is hundreds of degrees less than the temperature at inlet to the HP turbine: it is this temperature that is (very commonly) 'above the melting point of the blade material'
