Hi yall,
Could anyone explain about PW127F, I mean "P", "W", "1", "2", "7", "F' stands for?
Thanks in advance.:rolleyes:
Lets see if i can get this right
PW for Pratt and Whitney
1 Because its a PW100 series engine
27 for the approx thousand horse power produced (2780shp, at least I think thats what the 27 is for)
Not sure about the F. I thinks it to do with the engine model for the specific aircraft it is being used for.
The PW127F was used on the ATR72-500, the PW127E was used on the ATR42-500. But I believe all new ATR's being produced now have the PW127M
Hope that helps
Quazz :ok:

:ok: TQ again, the aircraft fits with PW127F, but the gnss system uses PW127M, did the french and italian engineers did something wrong or what?
Still need to know "F" stands for....... anyone else....

As said the F probably just refers to the engine's mounting type. An F will fit in to the ATR 72, where as the E varient is designed to fit the ATR 42. It'll be differences to the attachment points, intake/exhast fittings and possibly the control system eg FADEC/non FADEC.

PW127E, PW127F and PW127M are belong to the same family build.. They are almost 100% similar except to the few minor electronics differences. Were in fact a PW127E engine can be converted to PW127F by only changing the resistor of the EEC characterization plug for the purpose of increasing the power rating... If additional electronic device called DCU (data collector unit) will be attach to PW127F, then it will become PW127M model.
Hope Its help

In a prior millenium, what P&W called a Wasp received the US Military designation R-1340 (although its real displacement was 1344 cubic inches). More at http://www.enginehistory.org/P&W/PWdesignations.pdf
GE's T58 military turboshaft became a CT58 (surprise, surprise) in civil service. But the J79 was rebranded CJ805 for the Convair jets, the J85 became CJ610 for early bizjets, and the TF39 with revised fan became the CF6. The CF6-50 received a military F103 nameplate for the E-4B and KC-10. But when slung under a C-5M wing it's a F138 IIRC.
Oh, the foot bone's connected to the ankle bone...
